Number of steps per day needed to prevent death in diabetes
Walking 10,000 steps per day may reduce the risk of death for those who have trouble regulating their blood sugar, according to the findings from a study of almost 1,700 American adults with prediabetes or diabetes.
Researchers from the University of Seville, Spain, evaluated U.S. adults with prediabetes and diabetes using data from the Centers for Disease Control and Prevention’s National Health and Nutrition Examination Survey, collected between 2005 and 2006.
The findings were published this month in Diabetes Care.
Of the total, 1,194 adults had prediabetes, and 493 had diabetes. People with diabetes in the study were diagnosed by a doctor or had a fasting blood glucose level higher than 126 mg/dL. People with prediabetes in the study were also diagnosed by a doctor or had a fasting glucose level from 100 to 125 mg/dL.
Over half (56%) of prediabetic adults were male (average age 55 years), and they took an average of 8,500 steps per day. Half (51%) of the diabetic adults were also male (average age 61 years), and they took fewer steps per day – about 6,300.
The people in the study wore an accelerometer on their waist to count their steps for 7 consecutive days. The researchers adjusted for age, sex, ethnicity, smoking, alcohol use, diet, and use of diabetes medications.
Over 9 years, 200 people with prediabetes and 138 with diabetes died. Based on those who survived after follow-up, walking nearly 10,000 steps per day was best for reducing the risk of death from any cause for people with prediabetes and diabetes.
But about 20% of people in the study were removed from the analysis because they had invalid accelerometry data. Adults who are healthy enough to walk 10,000 steps may have different rates of death from those who aren’t, according to the study authors, who called for more research to compare these two groups.
If 10,000 steps seem like a daunting task, talking to a doctor about finding a routine that works for your physical ability could be helpful, the study authors suggest.

Marital status plays modest role in gastric cancer overall survival
, according to research published in the Journal of Investigative Medicine.
Tumor size remained the largest contributor to overall survival, but marital status was among several other significant factors, such as age, race, gender, treatment style, and pathologic stage, that can provide insight into a patient’s likelihood of overall survival, as it does with several other cancers.
“Married patients had the best prognosis, followed by single patients, and the prognosis of separated patients was the worst,” write Lixiang Zhang and colleagues at the First Affiliated Hospital of Anhui Medical University, Hefei, China. “We speculate that this might be due to the fact that married patients had better financial conditions and emotional encouragement, while separated patients might be more likely to experience financial difficulties [and] emotional loss.”
The results were not necessarily surprising to Richard M. Peek, Jr., MD, director of the division of gastroenterology and a professor of medicine at Vanderbilt University Medical Center, who was not involved in the research.
“Marital status is a reflection of support systems, and a strong support system is a prognosticator for increased compliance with medical appointments and medical therapies,” Dr. Peek told this news organization. “It is something to consider when somebody is being treated for gastric cancer, because if they don’t have a strong support system – and marital status can be a proxy for that – then they may need more intensive follow-up and surveillance, for example, than somebody who does not have that support system.”
Exploring the marital status–cancer survival connection
Gastric cancer is the third leading cause of cancer deaths across the world, causing 780,000 deaths in 2018, the authors note. Yet it’s difficult to accurately predict the prognosis in patients who undergo treatment for early stage gastric cancer. Previous research has found marital status to be associated with survival in prostate, cervical, and rectal cancers.
Mark A. Lewis, MD, director of gastrointestinal oncology at Intermountain Healthcare Cancer Center, Utah, told this news organization that the connection between marital status and cancer outcomes has been described previously, including in an even larger analysis using the U.S. Surveillance, Epidemiology, and End Results (SEER) database from 2013. That study found that “unmarried patients are at significantly higher risk of presentation with metastatic cancer, undertreatment, and death resulting from their cancer.”
In this study, the researchers compared marital status and survival rates among 3,647 patients with early-stage gastric cancer, using data from the SEER database. The study only included patients with tumors in the lamina propria, mucosa, and submucosa and excluded those with distant metastasis or distant lymph node metastases, a second cancer, no data on chemotherapy received, or unknown survival time.
Because they were using a nomogram and building a new predictive nomogram that would include marital status, the researchers divided the patient population into a training set of 2,719 patients and a testing set of 928 patients. Using overall survival as the primary endpoint, the analysis included the variables of “age at diagnosis, race, gender, tumor location, histology, grade, stage_T and stage_N, surgery in the primary site, lymph node dissection, chemotherapy, radiation, tumor size, insurance, and marital status,” the authors report.
Among the study population, 53.7% were married, 17.3% were widowed, 14% were single and never married, 7.5% were divorced, 1.1% were separated, and the status of 6.4% was unknown. Age at diagnosis, race, gender, histology, tumor grade, stage T, stage N, surgery type, tumor size, and insurance status were all significantly different between the marital status subgroups.
Married patients had the best prognosis, with an average overall survival of 72 months, compared with an average 60 months in widowed persons, the group with the poorest overall survival. Overall survival was higher in married women (76 months) than in married men (69 months). The same pattern held for women (62 months) and men (52 months) who had been widowed.
“It is worthy to note that survival was significantly better in divorced female patients than in divorced male patients,” the authors report. “Survival was better in female patients than in male patients” across all marital groups.
What long-term relationships reveal
These findings do not mean that simply getting married changes one’s likelihood of survival, however. Rather, a long-term relationship is revealing about other aspects in a person’s life.
“I think it represents more stability in the supportive relationship that you need to really deal with a serious disease like cancer,” Dr. Peek said.
If a patient does not have a long-term partner, their care team can ask other questions to get a sense of what their support network is like, Dr. Peek added. “We want to know, does anybody else live in the house with them? Do they have adequate transportation? Can they make medical appointments? Do they have somebody who can help with the medical issues that are going to come up? Do they have family in the area?”
Cancer treatment requires a multidisciplinary approach, and having someone other than just the patient around to help bring together the different aspects of care from different care teams can make a difference in how the patient fares, Dr. Peek explained. Patients without a strong support system may need closer follow-up and other accommodations, he said.
Providers “may schedule their clinical appointments closer together if they don’t have a support system, or they may be able to reach out and offer transportation assistance and those kinds of things that somebody living alone may need,” Dr. Peek said. Outside resources may be a higher priority for those who lack a support system at home, he added.
Dr. Peek also noted other factors that may play a role in a patient’s survival that these researchers did not have the data to address, such as socioeconomic status, employment, alcohol use, smoking, and infection with Helicobacter pylori, the strongest known risk factor for gastric cancer.
A potentially relevant limitation of the study is that it probably has some selection bias, because the patients who were included probably had the means to have received an earlier diagnosis, said Dr. Lewis, who was not involved in the research.
“Furthermore, just in terms of the group sizes, the baseline characteristics section makes it clear that the preponderance of patients were married, lending that group more statistical weight,” Dr. Lewis said.
“Of the seven attributes in the nomogram, the impact of the marital status seems comparatively meager relative to conventional clinicopathology risk factors like T stage,” he added.
“All in all, I think this study reinforces our awareness that socioeconomic status and social determinants of health play a huge role in cancer outcomes, but it’s not entirely clear that’s modifiable just by getting married,” Dr. Lewis said. “There is a saying in oncology that ‘expensive liquor causes less cancer than cheap liquor,’ which is not negating the carcinogenicity of alcohol but rather identifying different outcomes by socioeconomic status.”
The research was funded by the Natural Science Foundation of Anhui Province. The authors report no relevant financial relationships. Dr. Peek reports no relevant financial relationships. Dr. Lewis reports receiving speaking fees for AstraZeneca/Daiichi Sankyo and having done educational videos for Astellas.

Drug shortages plague hematology, but preparedness helps
Just before he took a call from a reporter asking about the impact of drug shortages in hematology, Bill Greene, PharmD, chief pharmaceutical officer at St. Jude Children’s Research Hospital, had spent an hour on the phone overseeing his institution’s response to a hematology drug shortage. The chemotherapy drug fludarabine, used to treat chronic lymphocytic leukemia, was in short supply.
“There are 5 different manufacturers, but none of them have had drug available over the past 2 weeks,” Dr. Greene said. “We’re trying to chase some emergency supplies to be able to continue treatment for patients who’ve had their treatments initiated and planned.”
Over the past several years, this predicament has become common at hematology clinics across the country. In fact, management of scarce medication resources has become a significant part of Dr. Greene’s workload these days, as critical drugs fail to show up on time or manufacturer supplies run low at his hospital in Memphis.
This shortage of hematology drugs got a new dose of national attention, thanks to a recent episode of CBS News’ “60 Minutes.” Through interviews with physicians and parents of children who suddenly could not get vital medications, the report highlighted the recent shortage of another leukemia drug, vincristine.
“As a cancer mom, we shouldn’t be fighting for our children to get a drug that is needed,” Cyndi Valenta was quoted as saying. She recalled that when the shortage began in 2019, her 13-year-old son, a leukemia patient at Loma Linda (Calif.) University Hospital, felt frightened. Ms. Valenta said she felt a “gut-wrenching feeling of just fear and anger.” They were finally able to get doses of the drug after launching a social media campaign.
Such drug shortages are especially widespread in oncology and hematology, according to a survey of oncology pharmacists at 68 organizations nationwide. Published in the May 2022 issue of Oncology Practice, the study showed that 63% of institutions reported one or more drug shortages every month, with a 34% increase in 2019, compared with 2018. Treatment delays, reduced doses, or alternative regimens were reported by 75% of respondents, the authors wrote.
The pharmacists surveyed between May 2019 and July 2020 were asked about the three most hard-to-get chemotherapy and supportive care agents. Vincristine topped the list, followed by vinblastine, IVIG, leucovorin, and BCG, as well as difficult-to-obtain ropine, erwinia asparaginase, etoposide, and leuprolide. Several of these drugs are used to treat conditions such as lymphoma and leukemia.
Eighty-two percent of respondents reported shortages of decitabine (IV), often used as part of a cocktail with vinblastine and other drugs to treat Hodgkin lymphoma.
The reasons for drug shortages are varied. The CBS News report declared that “pharmaceutical companies have stopped producing many life-saving generic drugs because they make too little profit,” and it suggested that the federal government isn’t doing enough.
But government action actually might be making a difference. According to the FDA, the number of new drug shortages has fallen dramatically from 250 in 2011 to 41 in 2021, and the number of prevented drug shortages rose from nearly 200 to more than 300 over that same period. Still, the number of ongoing drug shortages has risen from around 40 in 2017 to about 80 in 2021.
Reasons for the paucity of certain drugs are often unclear. In a June 12, 2022 post, for example, the American Society of Health-System Pharmacists’ drug shortage database noted that the chemotherapy drug fludarabine was in short supply and provided details about when some of the 5 manufacturers expected to have it available. (This is the shortage that Dr. Greene was trying to manage.) But 4 of the 5 manufacturers “did not provide a reason,” and the fifth blamed manufacturing delays.
“There’s a lot of closely held trade secrets that hinder the ability to share good information,” said Dr. Greene. To make things more complicated, shipping times are often unreliable. “The product doesn’t show up today, we place another order. Sometimes it will show up tomorrow, sometimes it doesn’t,” he said. “If you’re not tracking it carefully, you deplete your own supply.”
Patients’ families have grown used to dealing with drug shortages, and “they’re less quick to blame personnel at our institution.”
How can hematologists cope with this issue? “The best thing in the immediate term is to advocate for their hospital to have a pharmacist dedicated to shortage monitoring and taking proactive steps to obviate shortages,” hematologist/oncologist Andrew Hantel, MD, an instructor at Dana-Farber Cancer Institute, Harvard Medical School, Boston, said in an interview.
“We have ongoing communications with other large cancer centers and the FDA to recognize shortages early and develop plans to make sure we stay ahead of them,” Dr. Hantel said. “Most often this involves assessing supply, use rates, alternative manufacturers, and additional measures the Food and Drug Administration can take (for example, importation), and occasionally working with clinical teams to see if other medications are feasible alternatives.”
If a drug is unavailable, it can also be helpful to discuss alternative approaches. “We did not have any frank shortages of vincristine,” Dr. Hantel said, “but we did focus on conservation measures and considered different ethically appropriate ways to distribute vincristine if there was a point at which we did not have enough for everyone who needed it.”
If a drug is in short supply, options can include delaying treatment, giving an alternative, or providing the rest of the regimen without the scarce drug, he said. In a 2021 report in The Lancet Hematology, Dr. Hantel and his colleagues offered “model solutions for ethical allocation during cancer medicine shortages.”
The authors of the May 2022 drug-shortage report highlighted an alternative regimen in hematology. They noted that manufacturing delays have limited the supply of dacarbazine, used for Hodgkin lymphoma. Due to the current shortages, they wrote, clinicians are considering the use of escalated bleomycin, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone, replacing dacarbazine with procarbazine and using the doxorubicin, bleomycin, vinblastine, procarbazine, and prednisone regimen, or replacing dacarbazine with cyclophosphamide.
Dr. Greene emphasized the importance of tracking the news and the drug shortage websites run by the FDA and the American Society of Health-System Pharmacists.
It’s also crucial to have a good relationship with your wholesaler, he added, and to communicate about these problems within your facility. At his hospital, the pharmaceutical staff holds a multi-disciplinary meeting at least weekly to discuss the supply of medications. As he put it, “it’s a challenging environment.”
Dr. Greene and Dr. Hantel reported no relevant disclosures.

This shortage of hematology drugs got a new dose of national attention, thanks to a recent episode of CBS News’ “60 Minutes.” Through interviews with physicians and parents of children who suddenly could not get vital medications, the report highlighted the recent shortage of another leukemia drug, vincristine.
“As a cancer mom, we shouldn’t be fighting for our children to get a drug that is needed,” Cyndi Valenta was quoted as saying. She recalled that when the shortage began in 2019, her 13-year-old son, a leukemia patient at Loma Linda (Calif.) University Hospital, felt frightened. Ms. Valenta said she felt a “gut-wrenching feeling of just fear and anger.” They were finally able to get doses of the drug after launching a social media campaign.
Such drug shortages are especially widespread in oncology and hematology, according to a survey of oncology pharmacists at 68 organizations nationwide. Published in the May 2022 issue of Oncology Practice, the study showed that 63% of institutions reported one or more drug shortages every month, with a 34% increase in 2019, compared with 2018. Treatment delays, reduced doses, or alternative regimens were reported by 75% of respondents, the authors wrote.
The pharmacists surveyed between May 2019 and July 2020 were asked about the three most hard-to-get chemotherapy and supportive care agents. Vincristine topped the list, followed by vinblastine, IVIG, leucovorin, and BCG, as well as difficult-to-obtain ropine, erwinia asparaginase, etoposide, and leuprolide. Several of these drugs are used to treat conditions such as lymphoma and leukemia.
Eighty-two percent of respondents reported shortages of decitabine (IV), often used as part of a cocktail with vinblastine and other drugs to treat Hodgkin lymphoma.
The reasons for drug shortages are varied. The CBS News report declared that “pharmaceutical companies have stopped producing many life-saving generic drugs because they make too little profit,” and it suggested that the federal government isn’t doing enough.
But government action actually might be making a difference. According to the FDA, the number of new drug shortages has fallen dramatically from 250 in 2011 to 41 in 2021, and the number of prevented drug shortages rose from nearly 200 to more than 300 over that same period. Still, the number of ongoing drug shortages has risen from around 40 in 2017 to about 80 in 2021.
Reasons for the paucity of certain drugs are often unclear. In a June 12, 2022 post, for example, the American Society of Health-System Pharmacists’ drug shortage database noted that the chemotherapy drug fludarabine was in short supply and provided details about when some of the 5 manufacturers expected to have it available. (This is the shortage that Dr. Greene was trying to manage.) But 4 of the 5 manufacturers “did not provide a reason,” and the fifth blamed manufacturing delays.
“There’s a lot of closely held trade secrets that hinder the ability to share good information,” said Dr. Greene. To make things more complicated, shipping times are often unreliable. “The product doesn’t show up today, we place another order. Sometimes it will show up tomorrow, sometimes it doesn’t,” he said. “If you’re not tracking it carefully, you deplete your own supply.”
Patients’ families have grown used to dealing with drug shortages, and “they’re less quick to blame personnel at our institution.”
How can hematologists cope with this issue? “The best thing in the immediate term is to advocate for their hospital to have a pharmacist dedicated to shortage monitoring and taking proactive steps to obviate shortages,” hematologist/oncologist Andrew Hantel, MD, an instructor at Dana-Farber Cancer Institute, Harvard Medical School, Boston, said in an interview.
“We have ongoing communications with other large cancer centers and the FDA to recognize shortages early and develop plans to make sure we stay ahead of them,” Dr. Hantel said. “Most often this involves assessing supply, use rates, alternative manufacturers, and additional measures the Food and Drug Administration can take (for example, importation), and occasionally working with clinical teams to see if other medications are feasible alternatives.”
If a drug is unavailable, it can also be helpful to discuss alternative approaches. “We did not have any frank shortages of vincristine,” Dr. Hantel said, “but we did focus on conservation measures and considered different ethically appropriate ways to distribute vincristine if there was a point at which we did not have enough for everyone who needed it.”
If a drug is in short supply, options can include delaying treatment, giving an alternative, or providing the rest of the regimen without the scarce drug, he said. In a 2021 report in The Lancet Hematology, Dr. Hantel and his colleagues offered “model solutions for ethical allocation during cancer medicine shortages.”
The authors of the May 2022 drug-shortage report highlighted an alternative regimen in hematology. They noted that manufacturing delays have limited the supply of dacarbazine, used for Hodgkin lymphoma. Due to the current shortages, they wrote, clinicians are considering the use of escalated bleomycin, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone, replacing dacarbazine with procarbazine and using the doxorubicin, bleomycin, vinblastine, procarbazine, and prednisone regimen, or replacing dacarbazine with cyclophosphamide.
Dr. Greene emphasized the importance of tracking the news and the drug shortage websites run by the FDA and the American Society of Health-System Pharmacists.
It’s also crucial to have a good relationship with your wholesaler, he added, and to communicate about these problems within your facility. At his hospital, the pharmaceutical staff holds a multi-disciplinary meeting at least weekly to discuss the supply of medications. As he put it, “it’s a challenging environment.”
Dr. Greene and Dr. Hantel reported no relevant disclosures.
Just before he took a call from a reporter asking about the impact of drug shortages in hematology, Bill Greene, PharmD, chief pharmaceutical officer at St. Jude Children’s Research Hospital, had spent an hour on the phone overseeing his institution’s response to a hematology drug shortage. The chemotherapy drug fludarabine, used to treat chronic lymphocytic leukemia, was in short supply.
“There are 5 different manufacturers, but none of them have had drug available over the past 2 weeks,” Dr. Greene said. “We’re trying to chase some emergency supplies to be able to continue treatment for patients who’ve had their treatments initiated and planned.”
Over the past several years, this predicament has become common at hematology clinics across the country. In fact, management of scarce medication resources has become a significant part of Dr. Greene’s workload these days, as critical drugs fail to show up on time or manufacturer supplies run low at his hospital in Memphis.

Moderate drinking shows more benefit for older vs. younger adults
The health risks and benefits of moderate alcohol consumption are complex and remain a hot topic of debate. The data suggest that small amounts of alcohol may reduce the risk of certain health outcomes over time, but increase the risk of others, wrote Dana Bryazka, MS, a researcher at the Institute for Health Metrics and Evaluation (IHME) at the University of Washington, Seattle, and colleagues, in a paper published in the Lancet.
“The amount of alcohol that minimizes health loss is likely to depend on the distribution of underlying causes of disease burden in a given population. Since this distribution varies widely by geography, age, sex, and time, the level of alcohol consumption associated with the lowest risk to health would depend on the age structure and disease composition of that population,” the researchers wrote.
“We estimate that 1.78 million people worldwide died due to alcohol use in 2020,” Ms. Bryazka said in an interview. “It is important that alcohol consumption guidelines and policies are updated to minimize this harm, particularly in the populations at greatest risk,” she said.
“Existing alcohol consumption guidelines frequently vary by sex, with higher consumption thresholds set for males compared to females. Interestingly, with the currently available data we do not see evidence that risk of alcohol use varies by sex,” she noted.
Methods and results
In the study, the researchers conducted a systematic analysis of burden-weighted dose-response relative risk curves across 22 health outcomes. They used disease rates from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2020 for the years 1990-2020 for 21 regions, including 204 countries and territories. The data were analyzed by 5-year age group, sex, and year for individuals aged 15-95 years and older. The researchers estimated the theoretical minimum risk exposure level (TMREL) and nondrinker equivalent (NDE), meaning the amount of alcohol at which the health risk equals that of a nondrinker.
One standard drink was defined as 10 g of pure alcohol, equivalent to a small glass of red wine (100 mL or 3.4 fluid ounces) at 13% alcohol by volume, a can or bottle of beer (375 mL or 12 fluid ounces) at 3.5% alcohol by volume, or a shot of whiskey or other spirits (30 mL or 1.0 fluid ounces) at 40% alcohol by volume.
Overall, the TMREL was low regardless of age, sex, time, or geography, and varied from 0 to 1.87 standard drinks per day. However, it was lowest for males aged 15-39 years (0.136 drinks per day) and only slightly higher for females aged 15-39 (0.273), representing 1-2 tenths of a standard drink.
For adults aged 40 and older without any underlying health conditions, drinking a small amount of alcohol may provide some benefits, such as reducing the risk of ischemic heart disease, stroke, and diabetes, the researchers noted. In general, for individuals aged 40-64 years, TMRELs ranged from about half a standard drink per day (0.527 drinks for males and 0.562 standard drinks per day for females) to almost two standard drinks (1.69 standard drinks per day for males and 1.82 for females). For those older than 65 years, the TMRELs represented just over 3 standard drinks per day (3.19 for males and 3.51 for females). For individuals aged 40 years and older, the distribution of disease burden varied by region, but was J-shaped across all regions, the researchers noted.
The researchers also found that those individuals consuming harmful amounts of alcohol were most likely to be aged 15-39 (59.1%) and male (76.9%).
The study findings were limited by several factors including the observational design and lack of data on drinking patterns, such as binge drinking, the researchers noted. Other limitations include the lack of data reflecting patterns of alcohol consumption during the COVID-19 pandemic, and exclusion of outcomes often associated with alcohol use, such as depression, anxiety, and dementia, that might reduce estimates of TMREL and NDE.
However, the results add to the ongoing discussion of the relationship between moderate alcohol consumption and health, the researchers said.
“The findings of this study support the development of tailored guidelines and recommendations on alcohol consumption by age and across regions and highlight that existing low consumption thresholds are too high for younger populations in all regions,” they concluded.
Consider individual factors when counseling patients
The takeaway message for primary care is that alcohol consumed in moderation can reduce the risk of ischemic heart disease, stroke, and diabetes, Ms. Bryazka noted. “However, it also increases the risk of many cancers, intentional and unintentional injuries, and infectious diseases like tuberculosis,” she said. “Of these health outcomes, young people are most likely to experience injuries, and as a result, we find that there are significant health risks associated with consuming alcohol for young people. Among older individuals, the relative proportions of these outcomes vary by geography, and so do the risks associated with consuming alcohol,” she explained.
“Importantly, our analysis was conducted at the population level; when evaluating risk at the individual level, it is also important to consider other factors such as the presence of comorbidities and interactions between alcohol and medications,” she emphasized.
Health and alcohol interaction is complicated
“These findings seemingly contradict a previous [Global Burden of Diseases, Injuries, and Risk Factors Study] estimate published in The Lancet, which emphasized that any alcohol use, regardless of amount, leads to health loss across populations,” wrote Robyn Burton, PhD, and Nick Sheron, MD, both of King’s College, London, in an accompanying comment.
However, the novel methods of weighting relative risk curves according to levels of underlying disease drive the difference in results, along with disaggregated estimates by age, sex, and region, they said.
“Across most geographical regions in this latest analysis, injuries accounted for most alcohol-related harm in younger age groups. This led to a minimum risk level of zero, or very close to zero, among individuals aged 15-39 years across all geographical regions,” which is lower than the level for older adults because of the shift in alcohol-related disease burden towards cardiovascular disease and cancers, they said. “This highlights the need to consider existing rates of disease in a population when trying to determine the total harm posed by alcohol,” the commentators wrote.
In an additional commentary, Tony Rao, MD, a visiting clinical research fellow in psychiatry at King’s College, London, noted that “the elephant in the room with this study is the interpretation of risk based on outcomes for cardiovascular disease – particularly in older people. We know that any purported health benefits from alcohol on the heart and circulation are balanced out by the increased risk from other conditions such as cancer, liver disease, and mental disorders such as depression and dementia,” Dr. Rao said. “If we are to simply draw the conclusion that older people should continue or start drinking small amounts because it protects against diseases affecting heart and circulation – which still remains controversial – other lifestyle changes or the use of drugs targeted at individual cardiovascular disorders seem like a less harmful way of improving health and wellbeing.”
Data can guide clinical practice
No previous study has examined the effect of the theoretical minimum risk of alcohol consumption by geography, age, sex, and time in the context of background disease rates, said Noel Deep, MD, in an interview.
“This study enabled the researchers to quantify the proportion of the population that consumed alcohol in amounts that exceeded the thresholds by location, age, sex, and year, and this can serve as a guide in our efforts to target the control of alcohol intake by individuals,” said Dr. Deep, a general internist in private practice in Antigo, Wisc. He also serves as chief medical officer and a staff physician at Aspirus Langlade Hospital in Antigo.
The first take-home message for clinicians is that even low levels of alcohol consumption can have deleterious effects on the health of patients, and patients should be advised accordingly based on the prevalence of diseases in that community and geographic area, Dr. Deep said. “Secondly, clinicians should also consider the risk of alcohol consumption on all forms of health impacts in a given population rather than just focusing on alcohol-related health conditions,” he added.
“This study provides us with the data to tailor our efforts in educating the clinicians and the public about the relationship between alcohol consumption and disease outcomes based on the observed disease rates in each population,” Dr. Deep explained. “The data should provide another reason for physicians to advise their younger patients, especially the younger males, to avoid or minimize alcohol use,” he said. The data also can help clinicians formulate public health messaging and community education to reduce harmful alcohol use, he added.
As for additional research, Dr. Deep said he would like to see data on the difference in the health-related effects of alcohol in binge-drinkers vs. those who regularly consume alcohol on a daily basis. “It would probably also be helpful to figure out what type of alcohol is being studied and the quality of the alcohol,” he said.
The study was supported by the Bill and Melinda Gates Foundation. Ms. Bryazka and colleagues had no financial conflicts to disclose. Dr. Burton disclosed serving as a consultant to the World Health Organization European Office for the Prevention and Control of Noncommunicable Diseases. Dr. Sheron had no financial conflicts to disclose. Dr. Deep had no financial conflicts to disclose, but serves on the Editorial Advisory Board of Internal Medicine News.

Other limitations include the lack of data reflecting patterns of alcohol consumption during the COVID-19 pandemic, and exclusion of outcomes often associated with alcohol use, such as depression, anxiety, and dementia, that might reduce estimates of TMREL and NDE.
However, the results add to the ongoing discussion of the relationship between moderate alcohol consumption and health, the researchers said.
“The findings of this study support the development of tailored guidelines and recommendations on alcohol consumption by age and across regions and highlight that existing low consumption thresholds are too high for younger populations in all regions,” they concluded.
Consider individual factors when counseling patients
The takeaway message for primary care is that alcohol consumed in moderation can reduce the risk of ischemic heart disease, stroke, and diabetes, Ms. Bryazka noted. “However, it also increases the risk of many cancers, intentional and unintentional injuries, and infectious diseases like tuberculosis,” she said. “Of these health outcomes, young people are most likely to experience injuries, and as a result, we find that there are significant health risks associated with consuming alcohol for young people. Among older individuals, the relative proportions of these outcomes vary by geography, and so do the risks associated with consuming alcohol,” she explained.
“Importantly, our analysis was conducted at the population level; when evaluating risk at the individual level, it is also important to consider other factors such as the presence of comorbidities and interactions between alcohol and medications,” she emphasized.
Health and alcohol interaction is complicated
“These findings seemingly contradict a previous [Global Burden of Diseases, Injuries, and Risk Factors Study] estimate published in The Lancet, which emphasized that any alcohol use, regardless of amount, leads to health loss across populations,” wrote Robyn Burton, PhD, and Nick Sheron, MD, both of King’s College, London, in an accompanying comment.
However, the novel methods of weighting relative risk curves according to levels of underlying disease drive the difference in results, along with disaggregated estimates by age, sex, and region, they said.
“Across most geographical regions in this latest analysis, injuries accounted for most alcohol-related harm in younger age groups. This led to a minimum risk level of zero, or very close to zero, among individuals aged 15-39 years across all geographical regions,” which is lower than the level for older adults because of the shift in alcohol-related disease burden towards cardiovascular disease and cancers, they said. “This highlights the need to consider existing rates of disease in a population when trying to determine the total harm posed by alcohol,” the commentators wrote.
In an additional commentary, Tony Rao, MD, a visiting clinical research fellow in psychiatry at King’s College, London, noted that “the elephant in the room with this study is the interpretation of risk based on outcomes for cardiovascular disease – particularly in older people. We know that any purported health benefits from alcohol on the heart and circulation are balanced out by the increased risk from other conditions such as cancer, liver disease, and mental disorders such as depression and dementia,” Dr. Rao said. “If we are to simply draw the conclusion that older people should continue or start drinking small amounts because it protects against diseases affecting heart and circulation – which still remains controversial – other lifestyle changes or the use of drugs targeted at individual cardiovascular disorders seem like a less harmful way of improving health and wellbeing.”
Data can guide clinical practice
No previous study has examined the effect of the theoretical minimum risk of alcohol consumption by geography, age, sex, and time in the context of background disease rates, said Noel Deep, MD, in an interview.
“This study enabled the researchers to quantify the proportion of the population that consumed alcohol in amounts that exceeded the thresholds by location, age, sex, and year, and this can serve as a guide in our efforts to target the control of alcohol intake by individuals,” said Dr. Deep, a general internist in private practice in Antigo, Wisc. He also serves as chief medical officer and a staff physician at Aspirus Langlade Hospital in Antigo.
The first take-home message for clinicians is that even low levels of alcohol consumption can have deleterious effects on the health of patients, and patients should be advised accordingly based on the prevalence of diseases in that community and geographic area, Dr. Deep said. “Secondly, clinicians should also consider the risk of alcohol consumption on all forms of health impacts in a given population rather than just focusing on alcohol-related health conditions,” he added.
“This study provides us with the data to tailor our efforts in educating the clinicians and the public about the relationship between alcohol consumption and disease outcomes based on the observed disease rates in each population,” Dr. Deep explained. “The data should provide another reason for physicians to advise their younger patients, especially the younger males, to avoid or minimize alcohol use,” he said. The data also can help clinicians formulate public health messaging and community education to reduce harmful alcohol use, he added.
As for additional research, Dr. Deep said he would like to see data on the difference in the health-related effects of alcohol in binge-drinkers vs. those who regularly consume alcohol on a daily basis. “It would probably also be helpful to figure out what type of alcohol is being studied and the quality of the alcohol,” he said.

Amazon involved with new cancer vaccine clinical trial
The trial is aimed at finding “personalized vaccines” to treat breast cancer and melanoma. The phase 1 trial is recruiting 20 people over the age of 18 to study the safety of the vaccines, according to CNBC.
The Fred Hutchinson Cancer Research Center and University of Washington Cancer Consortium are listed as the researchers of the clinical trial, and Amazon is listed as a collaborator, according to a filing on the ClinicalTrials.gov database.
“Amazon is contributing scientific and machine learning expertise to a partnership with Fred Hutch to explore the development of a personalized treatment for certain forms of cancer,” an Amazon spokesperson told CNBC.
“It’s very early, but Fred Hutch recently received permission from the U.S. Food and Drug Administration to proceed with a phase 1 clinical trial, and it’s unclear whether it will be successful,” the spokesperson said. “This will be a long, multiyear process – should it progress, we would be open to working with other organizations in health care and life sciences that might also be interested in similar efforts.”
In recent years, Amazon has grown its presence in the health care industry, CNBC reported. The company launched an online pharmacy in 2020, developed a telehealth service called Amazon Care, and released its own COVID-19 test during the pandemic.
A research and development group inside Amazon, known as Grand Challenge, oversaw the company’s early cancer vaccine effort, according to Business Insider. It’s now under the purview of a cancer research team that reports to Robert Williams, the company’s vice president of devices.
The study was first posted on ClinicalTrials.gov in October 2021 and began recruiting patients on June 9, according to the filing. The phase 1 trial is expected to run through November 2023.
The phase 1 trial will study the safety of personalized vaccines to treat patients with late-stage melanoma or hormone receptor-positive HER2-negative breast cancer which has either spread to other parts of the body or doesn’t respond to treatment.
More information about the study can be found on ClinicalTrials.gov under the identifier NCT05098210.

Surgical Treatment of Nonmelanoma Skin Cancer in Older Adult Veterans
Skin cancer is the most diagnosed cancer in the United States. Nonmelanoma skin cancers (NMSC), which include basal cell carcinoma and squamous cell carcinoma, are usually cured with removal.1 The incidence of NMSC increases with age and is commonly found in nursing homes and geriatric units. These cancers are not usually metastatic or fatal but can cause local destruction and disfigurement if neglected.2 The current standard of care is to treat diagnosed NMSC; however, the dermatology and geriatric care literature have questioned the logic of treating asymptomatic skin cancers that will not affect a patient’s life expectancy.2-4
Forty-seven percent of the current living veteran population is aged ≥ 65 years.5 Older adult patients are frequently referred to the US Department of Veterans Affairs (VA) surgical service for the treatment of NMSC. The veteran population includes a higher percentage of individuals at an elevated risk of skin cancers (older, White, and male) compared with the general population.6 World War II veterans deployed in regions closer to the equator have been found to have an elevated risk of melanoma and nonmelanoma skin carcinomas.7 A retrospective study of Vietnam veterans exposed to Agent Orange (2,3,7,8-tetrachlorodibenzodioxin) found a significantly higher risk of invasive NMSC in Fitzpatrick skin types I-IV compared with an age-matched subset of the general population.8 Younger veterans who were deployed in Afghanistan and Iraq for Operation Enduring Freedom/Operation Iraqi Freedom worked at more equatorial latitudes than the rest of the US population and may be at increased risk of NMSC. Inadequate sunscreen access, immediate safety concerns, outdoor recreational activities, harsh weather, and insufficient emphasis on sun protection have created a multifactorial challenge for the military population. Riemenschneider and colleagues recommended targeted screening for at-risk veteran patients and prioritizing annual skin cancer screenings during medical mission physical examinations for active military.7
The plastic surgery service regularly receives consults from dermatology, general surgery, and primary care to remove skin cancers on the face, scalp, hands, and forearms. Skin cancer treatment can create serious hardships for older adult patients and their families with multiple appointments for the consult, procedure, and follow-up. Patients are often told to hold their anticoagulant medications when the surgery will be performed on a highly vascular region, such as the scalp or face. This can create wide swings in their laboratory test values and result in life-threatening complications from either bleeding or clotting. The appropriateness of offering surgery to patients with serious comorbidities and a limited life expectancy has been questioned.2-4 The purpose of this study was to measure the morbidity and unrelated 5-year mortality for patients with skin cancer referred to the plastic surgery service to help patients and families make a more informed treatment decision, particularly when the patients are aged > 80 years and have significant life-threatening comorbidities.
Methods
The University of Florida and Malcom Randall VA Medical Center Institutional review board in Gainesville, approved a retrospective review of all consults completed by the plastic surgery service for the treatment of NMSC performed from July 1, 2011 to June 30, 2015. Data collected included age and common life-limiting comorbidities at the time of referral. Morbidities were found on the electronic health record, including coronary artery disease (CAD), congestive heart failure (CHF), cerebral vascular disease (CVD), peripheral vascular disease, dementia, chronic kidney disease (CKD), chronic obstructive pulmonary disease (COPD), tobacco use, diabetes mellitus (DM), liver disease, alcohol use, and obstructive sleep apnea.
Treatment, complications, and 5-year mortality were recorded. A χ2 analysis with P value < .05 was used to determine statistical significance between individual risk factors and 5-year mortality. The relative risk of 5-year mortality was calculated by combining advanced age (aged > 80 years) with the individual comorbidities.
Results
Over 4 years, 800 consults for NMSC were completed by the plastic surgery service. Treatment decisions included 210 excisions (with or without reconstruction) in the operating room, 402 excisions (with or without reconstruction) under local anesthesia in clinic, 55 Mohs surgical dermatology referrals, 21 other service or hospital referrals, and 112 patient who were observed, declined intervention, or died prior to intervention. Five-year mortality was 28.6%. No patients died of NMSC. The median age at consult submission for patients deceased 5 years later was 78 years. Complication rate was 5% and included wound infection, dehiscence, bleeding, or graft loss. Two patients, both deceased within 5 years, had unplanned admissions due to bleeding from either a skin graft donor site or recipient bleeding. Aged ≥ 80 years, CAD, CHF, CVD, peripheral vascular disease, dementia, CKD, COPD, and DM were all found individually to be statistically significant predictors of 5-year mortality (Table 1). Combining aged ≥ 80 years plus CAD, CHF, or dementia all increased the 5-year mortality by a relative risk of > 3 (Table 2).
Discussion
The standard of care is to treat NMSC. Most NMSCs are treated surgically without consideration of patient age or life expectancy.2,4,9,10 A prospective cohort study involving a university-based private practice and a VA medical center in San Francisco found a 22.6% overall 5-year mortality and a 43.3% mortality in the group defined as limited life expectancy (LLE) based on age (≥ 85 years) and medical comorbidities. None died due to the NMSC. Leading cause of death was cardiac, cerebrovascular, and respiratory disease, lung and prostate cancer, and Alzheimer disease. The authors suggested the LLE group may be exposed to wound complications without benefiting from the treatment.4
Another study of 440 patients receiving excision for biopsy-proven facial NMSC at the Roudebush VA Medical Center in Indianapolis, Indiana, found no residual carcinoma in 35.3% of excisions, and in patients aged > 90 years, more than half of the excisions had no residual carcinoma. More than half of the patients aged > 90 years died within 1 year, not as a result of the NMSC. The authors argued for watchful waiting in select patients to maximize comfort and outcomes.10
NMSCs are often asymptomatic and not immediately life threatening. Although NMSCs tend to have a favorable prognosis, studies have found that NMSC may be a marker for other poor health outcomes. A significant increased risk for all-cause mortality was found for patients with a history of SCC, which may be attributed to immune status.11 The aging veteran population has more complex health care needs to be considered when developing surgical treatment plans. These medical problems may limit their life expectancy much sooner than the skin cancer will become symptomatic. We found that individuals aged ≥ 80 years who had CAD, CHF, or dementia had a relative risk of 3 or higher for 5-year mortality. The leading cause of death in the United States in years 2011 to 2015 was heart disease. Alzheimer disease was the sixth leading cause of death in those same years.12-14
Skin cancer excisions do not typically require general anesthesia, deep sedation, or large fluid shifts; however, studies have found that when frail patients undergo low-risk procedures, they tend to have a higher mortality rate than their healthier counterparts.15 Frailty is a concept that identifies patients who are at increased risk of dying in 6 to 60 months due to a decline in their physical reserve. Frail patients have increased rates of perioperative mortality and complications. Various tools have been used to assess the components of physical performance, speed, mobility, nutrition status, mental health, and cognition.16 Frailty screening has been initiated in several VA hospitals, including our own in Gainesville, Florida, with the goal of decreasing postoperative morbidity and mortality in older adult patients.17 The patients are given a 1-page screening assessment that asks about their living situation, medical conditions, nutrition status, cognition, and activities of daily living. The results can trigger the clinician to rethink the surgical plan and mobilize more resources to optimize the patient’s health. This study period precedes the initiative at our institution.
The plastic surgery service’s routine practice is to excise skin cancers in the operating room if sedation or general anesthesia will be needed (Figure 1A), for optimal control of bleeding (Figure 1B) in a patient who cannot safely stop blood thinners, or for excision of a highly vascularized area such as the scalp. Surgery is offered in an office-based setting if the area can be closed primarily, left open to close secondarily, or closed with a small skin graft under local anesthesia only (Figure 2). We prefer treating frail patients in the minor procedure clinic, when possible, to avoid the risks of sedation and the additional preoperative visits and transportation requirements. NMSC with unclear margins (Figure 3A) or in cosmetically sensitive areas where tissue needs to be preserved (Figure 3B) are referred to the Mohs dermatologist. The skin cancers in this study were most frequently found on the face, scalp, hands, and forearms based on referral patterns.
Other treatment options for NMSC include curettage and electrodessication, cryotherapy, and radiation; however, ours is a surgical service and patients are typically referred to us by primary care or dermatology when those are not reasonable or desirable options.18 Published complication rates of patients having skin cancer surgery without age restriction have a rate of 3% to 6%, which is consistent with our study of 5%.19-21 Two bleeding complications that needed to be admitted did not require more than a bedside procedure and neither required transfusions. One patient had been instructed to continue taking coumadin during the perioperative office-based procedure due to a recent carotid stent placement in the setting of a rapidly growing basal cell on an easily accessible location.
The most noted comorbidity in patients with wound complications was found to be DM; however, this was not found to be a statistically significant risk factor for wound complications (P = .10). We do not have a set rule for advising for or against NMSC surgery. We do counsel frail patients and their families that not all cancer is immediately life threatening and will work with them to do whatever makes the most sense to achieve their goals, occasionally accepting positive margins in order to debulk a symptomatic growth. The objective of this paper is to contribute to the discussion of performing invasive procedures on older adult veterans with life-limiting comorbidities. Patients and their families will have different thresholds for what they feel needs intervention, especially if other medical problems are consuming much of their time. We also have the community care referral option for patients whose treatment decisions are being dictated by travel hardships.
Strengths and Limitations
A strength of this study is that the data were obtained from a closed system. Patients tend to stay long-term within the VA and their health record is accessible throughout the country as long as they are seen at a VA facility. Complications, therefore, return to the treating service or primary care, who would route the patient back to the surgeon.
One limitation of the study is that this is a retrospective review from 2011. The authors are limited to data that are recorded in the patient record. Multiple health care professionals saw the patients and notes lack consistency in detail. Size of the lesions were not consistently recorded and did not get logged into our database for that reason.
Conclusions
Treatment of NMSC in older adult patients has a low morbidity but needs to be balanced against a patient and family’s goals when the patient presents with life-limiting comorbidities. An elevated 5-year mortality in patients aged > 80 years with serious unrelated medical conditions is intuitive, but this study may help put treatment plans into perspective for families and health care professionals who want to provide an indicated service while maximizing patient quality of life.

Five-year mortality was 28.6%. No patients died of NMSC. The median age at consult submission for patients deceased 5 years later was 78 years. Complication rate was 5% and included wound infection, dehiscence, bleeding, or graft loss. Two patients, both deceased within 5 years, had unplanned admissions due to bleeding from either a skin graft donor site or recipient bleeding. Aged ≥ 80 years, CAD, CHF, CVD, peripheral vascular disease, dementia, CKD, COPD, and DM were all found individually to be statistically significant predictors of 5-year mortality (Table 1). Combining aged ≥ 80 years plus CAD, CHF, or dementia all increased the 5-year mortality by a relative risk of > 3 (Table 2).
Discussion
The standard of care is to treat NMSC. Most NMSCs are treated surgically without consideration of patient age or life expectancy.2,4,9,10 A prospective cohort study involving a university-based private practice and a VA medical center in San Francisco found a 22.6% overall 5-year mortality and a 43.3% mortality in the group defined as limited life expectancy (LLE) based on age (≥ 85 years) and medical comorbidities. None died due to the NMSC. Leading cause of death was cardiac, cerebrovascular, and respiratory disease, lung and prostate cancer, and Alzheimer disease. The authors suggested the LLE group may be exposed to wound complications without benefiting from the treatment.4
Another study of 440 patients receiving excision for biopsy-proven facial NMSC at the Roudebush VA Medical Center in Indianapolis, Indiana, found no residual carcinoma in 35.3% of excisions, and in patients aged > 90 years, more than half of the excisions had no residual carcinoma. More than half of the patients aged > 90 years died within 1 year, not as a result of the NMSC. The authors argued for watchful waiting in select patients to maximize comfort and outcomes.10
NMSCs are often asymptomatic and not immediately life threatening. Although NMSCs tend to have a favorable prognosis, studies have found that NMSC may be a marker for other poor health outcomes. A significant increased risk for all-cause mortality was found for patients with a history of SCC, which may be attributed to immune status.11 The aging veteran population has more complex health care needs to be considered when developing surgical treatment plans. These medical problems may limit their life expectancy much sooner than the skin cancer will become symptomatic. We found that individuals aged ≥ 80 years who had CAD, CHF, or dementia had a relative risk of 3 or higher for 5-year mortality. The leading cause of death in the United States in years 2011 to 2015 was heart disease. Alzheimer disease was the sixth leading cause of death in those same years.12-14
Skin cancer excisions do not typically require general anesthesia, deep sedation, or large fluid shifts; however, studies have found that when frail patients undergo low-risk procedures, they tend to have a higher mortality rate than their healthier counterparts.15 Frailty is a concept that identifies patients who are at increased risk of dying in 6 to 60 months due to a decline in their physical reserve. Frail patients have increased rates of perioperative mortality and complications. Various tools have been used to assess the components of physical performance, speed, mobility, nutrition status, mental health, and cognition.16 Frailty screening has been initiated in several VA hospitals, including our own in Gainesville, Florida, with the goal of decreasing postoperative morbidity and mortality in older adult patients.17 The patients are given a 1-page screening assessment that asks about their living situation, medical conditions, nutrition status, cognition, and activities of daily living. The results can trigger the clinician to rethink the surgical plan and mobilize more resources to optimize the patient’s health. This study period precedes the initiative at our institution.
The plastic surgery service’s routine practice is to excise skin cancers in the operating room if sedation or general anesthesia will be needed (Figure 1A), for optimal control of bleeding (Figure 1B) in a patient who cannot safely stop blood thinners, or for excision of a highly vascularized area such as the scalp. Surgery is offered in an office-based setting if the area can be closed primarily, left open to close secondarily, or closed with a small skin graft under local anesthesia only (Figure 2). We prefer treating frail patients in the minor procedure clinic, when possible, to avoid the risks of sedation and the additional preoperative visits and transportation requirements. NMSC with unclear margins (Figure 3A) or in cosmetically sensitive areas where tissue needs to be preserved (Figure 3B) are referred to the Mohs dermatologist. The skin cancers in this study were most frequently found on the face, scalp, hands, and forearms based on referral patterns.
Other treatment options for NMSC include curettage and electrodessication, cryotherapy, and radiation; however, ours is a surgical service and patients are typically referred to us by primary care or dermatology when those are not reasonable or desirable options.18 Published complication rates of patients having skin cancer surgery without age restriction have a rate of 3% to 6%, which is consistent with our study of 5%.19-21 Two bleeding complications that needed to be admitted did not require more than a bedside procedure and neither required transfusions. One patient had been instructed to continue taking coumadin during the perioperative office-based procedure due to a recent carotid stent placement in the setting of a rapidly growing basal cell on an easily accessible location.
The most noted comorbidity in patients with wound complications was found to be DM; however, this was not found to be a statistically significant risk factor for wound complications (P = .10). We do not have a set rule for advising for or against NMSC surgery. We do counsel frail patients and their families that not all cancer is immediately life threatening and will work with them to do whatever makes the most sense to achieve their goals, occasionally accepting positive margins in order to debulk a symptomatic growth. The objective of this paper is to contribute to the discussion of performing invasive procedures on older adult veterans with life-limiting comorbidities. Patients and their families will have different thresholds for what they feel needs intervention, especially if other medical problems are consuming much of their time. We also have the community care referral option for patients whose treatment decisions are being dictated by travel hardships.
Strengths and Limitations
A strength of this study is that the data were obtained from a closed system. Patients tend to stay long-term within the VA and their health record is accessible throughout the country as long as they are seen at a VA facility. Complications, therefore, return to the treating service or primary care, who would route the patient back to the surgeon.
One limitation of the study is that this is a retrospective review from 2011. The authors are limited to data that are recorded in the patient record. Multiple health care professionals saw the patients and notes lack consistency in detail. Size of the lesions were not consistently recorded and did not get logged into our database for that reason.
Conclusions
Treatment of NMSC in older adult patients has a low morbidity but needs to be balanced against a patient and family’s goals when the patient presents with life-limiting comorbidities. An elevated 5-year mortality in patients aged > 80 years with serious unrelated medical conditions is intuitive, but this study may help put treatment plans into perspective for families and health care professionals who want to provide an indicated service while maximizing patient quality of life.

Skin cancer is the most diagnosed cancer in the United States. Nonmelanoma skin cancers (NMSC), which include basal cell carcinoma and squamous cell carcinoma, are usually cured with removal.1 The incidence of NMSC increases with age and is commonly found in nursing homes and geriatric units. These cancers are not usually metastatic or fatal but can cause local destruction and disfigurement if neglected.2 The current standard of care is to treat diagnosed NMSC; however, the dermatology and geriatric care literature have questioned the logic of treating asymptomatic skin cancers that will not affect a patient’s life expectancy.2-4
Forty-seven percent of the current living veteran population is aged ≥ 65 years.5 Older adult patients are frequently referred to the US Department of Veterans Affairs (VA) surgical service for the treatment of NMSC. The veteran population includes a higher percentage of individuals at an elevated risk of skin cancers (older, White, and male) compared with the general population.6 World War II veterans deployed in regions closer to the equator have been found to have an elevated risk of melanoma and nonmelanoma skin carcinomas.7 A retrospective study of Vietnam veterans exposed to Agent Orange (2,3,7,8-tetrachlorodibenzodioxin) found a significantly higher risk of invasive NMSC in Fitzpatrick skin types I-IV compared with an age-matched subset of the general population.8 Younger veterans who were deployed in Afghanistan and Iraq for Operation Enduring Freedom/Operation Iraqi Freedom worked at more equatorial latitudes than the rest of the US population and may be at increased risk of NMSC. Inadequate sunscreen access, immediate safety concerns, outdoor recreational activities, harsh weather, and insufficient emphasis on sun protection have created a multifactorial challenge for the military population. Riemenschneider and colleagues recommended targeted screening for at-risk veteran patients and prioritizing annual skin cancer screenings during medical mission physical examinations for active military.7
The plastic surgery service regularly receives consults from dermatology, general surgery, and primary care to remove skin cancers on the face, scalp, hands, and forearms. Skin cancer treatment can create serious hardships for older adult patients and their families with multiple appointments for the consult, procedure, and follow-up. Patients are often told to hold their anticoagulant medications when the surgery will be performed on a highly vascular region, such as the scalp or face. This can create wide swings in their laboratory test values and result in life-threatening complications from either bleeding or clotting. The appropriateness of offering surgery to patients with serious comorbidities and a limited life expectancy has been questioned.2-4 The purpose of this study was to measure the morbidity and unrelated 5-year mortality for patients with skin cancer referred to the plastic surgery service to help patients and families make a more informed treatment decision, particularly when the patients are aged > 80 years and have significant life-threatening comorbidities.
Methods
The University of Florida and Malcom Randall VA Medical Center Institutional review board in Gainesville, approved a retrospective review of all consults completed by the plastic surgery service for the treatment of NMSC performed from July 1, 2011 to June 30, 2015. Data collected included age and common life-limiting comorbidities at the time of referral. Morbidities were found on the electronic health record, including coronary artery disease (CAD), congestive heart failure (CHF), cerebral vascular disease (CVD), peripheral vascular disease, dementia, chronic kidney disease (CKD), chronic obstructive pulmonary disease (COPD), tobacco use, diabetes mellitus (DM), liver disease, alcohol use, and obstructive sleep apnea.
Treatment, complications, and 5-year mortality were recorded. A χ2 analysis with P value < .05 was used to determine statistical significance between individual risk factors and 5-year mortality. The relative risk of 5-year mortality was calculated by combining advanced age (aged > 80 years) with the individual comorbidities.
Results
Over 4 years, 800 consults for NMSC were completed by the plastic surgery service. Treatment decisions included 210 excisions (with or without reconstruction) in the operating room, 402 excisions (with or without reconstruction) under local anesthesia in clinic, 55 Mohs surgical dermatology referrals, 21 other service or hospital referrals, and 112 patient who were observed, declined intervention, or died prior to intervention. Five-year mortality was 28.6%. No patients died of NMSC. The median age at consult submission for patients deceased 5 years later was 78 years. Complication rate was 5% and included wound infection, dehiscence, bleeding, or graft loss. Two patients, both deceased within 5 years, had unplanned admissions due to bleeding from either a skin graft donor site or recipient bleeding. Aged ≥ 80 years, CAD, CHF, CVD, peripheral vascular disease, dementia, CKD, COPD, and DM were all found individually to be statistically significant predictors of 5-year mortality (Table 1). Combining aged ≥ 80 years plus CAD, CHF, or dementia all increased the 5-year mortality by a relative risk of > 3 (Table 2).

Nodular Sclerosing Hodgkin Lymphoma With Paraneoplastic Cerebellar Degeneration
Paraneoplastic syndrome is a rare disorder involving manifestations of immune dysregulation triggered by malignancy. The immune system develops antibodies to the malignancy, which can cause cross reactivation with various tissues in the body, resulting in an autoimmune response. Paraneoplastic cerebellar degeneration (PCD) is a rare condition caused by immune-mediated damage to the Purkinje cells of the cerebellar tract. Symptoms may include gait instability, double vision, decreased fine motor skills, and ataxia, with progression to brainstem-associated symptoms, such as nystagmus, dysarthria, and dysphagia. Early detection and treatment of the underlying malignancy is critical to halt the progression of autoimmune-mediated destruction. We present a case of a young adult female patient with PCD caused by Purkinje cell cytoplasmic–Tr (PCA-Tr) antibody with Hodgkin lymphoma.
Case Presentation
A 20-year-old previously healthy active-duty female patient presented to the emergency department with acute worsening of chronic intermittent, recurrent episodes of lightheadedness and vertigo. Symptoms persisted for 9 months until acutely worsening over the 2 weeks prior to presentation. She reported left eye double vision but did not report seeing spots, photophobia, tinnitus, or headache. She felt off-balance, leaning on nearby objects to remain standing. Symptoms primarily occurred during ambulation; however, occasionally they happened at rest. Episodes lasted up to several minutes and occurred up to 15 times a day. The patient reported no fever, night sweats, unexplained weight loss, muscle aches, weakness, numbness or tingling, loss of bowel or bladder function, or rash. She had no recent illnesses, changes to medications, or recent travel. Oral intake to include food and water was adequate and unchanged. The patient had a remote history of mild concussions without loss of consciousness while playing sports 4 years previously. She reported no recent trauma. Nine months before, she received treatment for benign paroxysmal positional vertigo (BPPV) with the Epley maneuver with full resolution of symptoms lasting several days. She reported no prescription or over-the-counter medications, herbal remedies, or supplements. She reported no other medical or surgical history and no pertinent social or family history.
Physical examination revealed a nontoxic-appearing female patient with intermittent conversational dysarthria, saccadic pursuits, horizontal nystagmus with lateral gaze, and vertical nystagmus with vertical gaze. The patient exhibited dysdiadochokinesia, or impaired ability to perform rapid alternating hand movements with repetition. Finger-to-nose testing was impaired and heel-to-shin motion remained intact. A Romberg test was positive, and the patient had tandem gait instability. Strength testing, sensation, reflexes, and cranial nerves were otherwise intact. Initial laboratory testing was unremarkable except for mild normocytic anemia. Her infectious workup, including testing for venereal disease, HIV, COVID-19, and Coccidioidies was negative. Heavy metals analysis and urine drug screen were negative. Ophthalmology was consulted and workup revealed small amplitude downbeat nystagmus in primary gaze, sustained gaze evoked lateral beating jerk nystagmus with rebound nystagmus R>L gaze, but there was no evidence of afferent package defect and optic nerve function remained intact. Magnetic resonance imaging of the brain demonstrated cerebellar vermis hypoplasia with prominence of the superior cerebellar folia. Due to concerns for autoimmune encephalitis, a lumbar puncture was performed. Antibody testing revealed PCA-Tr antibodies, which is commonly associated with Hodgkin lymphoma, prompting further evaluation for malignancy.
Computed tomography (CT) of the chest with contrast demonstrated multiple mediastinal masses with a conglomeration of lymph nodes along the right paratracheal region. Further evaluation was performed with a positron emission tomography (PET)–CT, revealing a large conglomeration of hypermetabolic pretracheal, mediastinal, and right supraclavicular lymph that were suggestive of lymphoma. Mediastinoscopy with excisional lymph node biopsy was performed with immunohistochemical staining confirming diagnosis of a nodular sclerosing variant of Hodgkin lymphoma. The patient was treated with IV immunoglobulin at 0.4g/kg daily for 5 days. A central venous catheter was placed into the patient’s right internal jugular vein and a chemotherapy regimen of doxorubicin 46 mg, vinblastine 11 mg, bleomycin 19 units, and dacarbazine 700 mg was initiated. The patient’s symptoms improved with resolution of dysarthria; however, her visual impairment and gait instability persisted. Repeat PET-CT imaging 2 months later revealed interval improvement with decreased intensity and extent of the hypermetabolic lymph nodes and no new hypermetabolic foci.
Discussion
PCA-Tr antibodies affect the delta/notchlike epidermal growth factor–related receptor, expressed on the dendrites of cerebellar Purkinje cells.1 These fibers are the only output neurons of the cerebellar cortex and are critical to the coordination of motor movements, accounting for the ataxia experienced by patients with this subtype of PCD.2 The link between Hodgkin lymphoma and PCA-Tr antibodies has been established; however, most reports involve men with a median age of 61 years with lymphoma-associated symptoms (such as lymphadenopathy) or systemic symptoms (fever, night sweats, or weight loss) preceding neurologic manifestations in 80% of cases.3
Our patient was a young, previously healthy adult female who initially presented with vertigo, a common concern with frequently benign origins. Although there was temporary resolution of symptoms after Epley maneuvers, symptoms recurred and progressed over several months to include brainstem manifestations of nystagmus, diplopia, and dysarthria. Previous reports indicate that after remission of the Hodgkin lymphoma, PCA-Tr antibodies disappear and symptoms can improve or resolve.4,5 Treatment has just begun for our patient and although there has been initial clinical improvement, given the chronicity of symptoms, it is unclear if complete resolution will be achieved.
Conclusions
PCD can result in debilitating neurologic dysfunction and may be associated with malignancy such as Hodgkin lymphoma. This case offers unique insight due to the patient’s demographics and presentation, which involved brainstem pathology typically associated with late-onset disease and preceded by constitutional symptoms. Clinical suspicion of this rare disorder should be considered in all ages, especially if symptoms are progressive or neurologic manifestations arise, as early detection and treatment of the underlying malignancy are paramount to the prevention of significant disability.

Cancer drug significantly cuts risk for COVID-19 death
, an interim analysis of a phase 3 placebo-controlled trial found.
Sabizabulin treatment consistently and significantly reduced deaths across patient subgroups “regardless of standard of care treatment received, baseline World Health Organization scores, age, comorbidities, vaccination status, COVID-19 variant, or geography,” study investigator Mitchell Steiner, MD, chairman, president, and CEO of Veru, said in a news release.
The company has submitted an emergency use authorization request to the U.S. Food and Drug Administration to use sabizabulin to treat COVID-19.
The analysis was published online in NEJM Evidence.
Sabizabulin, originally developed to treat metastatic castration-resistant prostate cancer, is a novel, investigational, oral microtubule disruptor with dual antiviral and anti-inflammatory activities. Given the drug’s mechanism, researchers at Veru thought that sabizabulin could help treat lung inflammation in patients with COVID-19 as well.
Findings of the interim analysis are based on 150 adults hospitalized with moderate to severe COVID-19 at high risk for acute respiratory distress syndrome and death. The patients were randomly allocated to receive 9 mg oral sabizabulin (n = 98) or placebo (n = 52) once daily for up to 21 days.
Overall, the mortality rate was 20.2% in the sabizabulin group vs. 45.1% in the placebo group. Compared with placebo, treatment with sabizabulin led to a 24.9–percentage point absolute reduction and a 55.2% relative reduction in death (odds ratio, 3.23; P = .0042).
The key secondary endpoint of mortality through day 29 also favored sabizabulin over placebo, with a mortality rate of 17% vs. 35.3%. In this scenario, treatment with sabizabulin resulted in an absolute reduction in deaths of 18.3 percentage points and a relative reduction of 51.8%.
Sabizabulin led to a significant 43% relative reduction in ICU days, a 49% relative reduction in days on mechanical ventilation, and a 26% relative reduction in days in the hospital, compared with placebo.
Adverse and serious adverse events were also lower in the sabizabulin group (61.5%) than the placebo group (78.3%).
The data are “pretty impressive and in a group of patients that we really have limited things to offer,” Aaron Glatt, MD, a spokesperson for the Infectious Diseases Society of America and chief of infectious diseases and hospital epidemiologist at Mount Sinai South Nassau in Oceanside, N.Y., said in an interview. “This is an interim analysis and obviously we’d like to see more data, but it certainly is something that is novel and quite interesting.”
David Boulware, MD, MPH, an infectious disease expert at the University of Minnesota, Minneapolis, told the New York Times that the large number of deaths in the placebo group seemed “rather high” and that the final analysis might reveal a more modest benefit for sabizabulin.
“I would be skeptical” that the reduced risk for death remains 55%, he noted.
The study was funded by Veru Pharmaceuticals. Several authors are employed by the company or have financial relationships with the company.

FROM NEJM EVIDENCE
Select patients with breast cancer may skip RT after lumpectomy
The women in this trial who skipped radiotherapy, and were treated with breast-conserving surgery followed by endocrine therapy, had an overall survival rate of 97.2%. The local recurrence rate was 2.3%, which was the study’s primary endpoint.
“Women 55 and over, with low-grade luminal A-type breast cancer, following breast conserving surgery and treated with endocrine therapy alone, had a very low rate of local recurrence at 5 years,” commented lead author Timothy Joseph Whelan, MD.
“The prospective and multicenter nature of this study supports that these patients are candidates for the omission of radiotherapy,” said Dr. Whelan, oncology professor and Canada Research Chair in Breast Cancer Research at McMaster University and a radiation oncologist at the Juravinski Cancer Centre, both in Hamilton, Ont.
“Over 300,000 [people] are diagnosed with invasive breast cancer in North America annually, the majority in the United States,” said Dr. Whelan. “We estimate that these results could apply to 10%-15% of them, so about 30,000-40,000 women per year who could avoid the morbidity, the cost, and inconvenience of radiotherapy.”
The results were presented at the annual meeting of the American Society of Clinical Oncology.
Dr. Whelan explained that adjuvant radiation therapy is generally prescribed following breast conservation therapy to lower the risk of local recurrence, but the treatment is also associated with acute and late toxicity. In addition, it can incur high costs and inconvenience for the patient.
Previous studies have found that among women older than 60 with low-grade, luminal A-type breast cancer who received only breast-conserving surgery, there was a low rate of local recurrence. In women aged older than 70 years, the risk of local recurrence was about 4%-5%.
This latest study focused on patients with breast cancer with a luminal A subtype combined with clinical pathological factors (defined as estrogen receptor ≥ 1%, progesterone receptor > 20%, HER2 negative, and Ki67 ≤ 13.25%).
This was a prospective, multicenter cohort study that included 501 patients aged 55 years and older who had undergone breast-conserving surgery for grade 1-2 T1N0 cancer.
The median patient age was 67, with 442 (88%) older than 75 years. The median tumor size was 1.1 cm.
Median follow-up was 5 years. The cohort was followed every 6 months for the first 2 years and then annually.
The primary outcome was local recurrence defined as time from enrollment to any invasive or noninvasive cancer in the ipsilateral breast, and secondary endpoints included contralateral breast cancer, relapse-free survival based on any recurrence, disease free survival, second cancer or death, and overall survival.
At five years, there were 10 events of local recurrence, for a rate of 2.3%. For secondary outcomes, there were eight events of contralateral breast cancer (1.9%); 12 relapses for a recurrence-free survival rate of 97.3%; 47 disease progression (23 second nonbreast cancers) for a disease-free survival rate of 89.9%; and 13 deaths, including 1 from breast cancer, for an overall survival of 97.2%.
Confirms earlier data
Penny R. Anderson, MD, professor in the department of radiation oncology at Fox Chase Cancer Center, Philadelphia, commented that this was an “extremely well-designed and important study.
“It has identified a specific subset of patients to be appropriate candidates for consideration of omission of adjuvant breast radiation therapy after breast-conserving surgery,” she added.
Although previously published trials have helped identify certain patient groups who have a low risk of local recurrence – and therefore, for whom it may be appropriate to omit radiation – they have been based on the traditional clinical and pathologic factors of tumor size, margin status, receptor status, and patient age.
“This LUMINA trial utilizes the molecular-defined intrinsic subtype of luminal A breast cancer to provide additional prognostic information,” she said. “This finding certainly suggests that this group of patients are ideal candidates for the omission of radiation, and that this should be discussed with these patients as a potential option in their treatment management.”
Overall, this trial is a “significant addition and a very relevant contribution to the literature demonstrating that adjuvant breast radiation may safely be omitted in this particular subgroup of breast cancer patients,” she said.
Unanswered questions
Commenting on the study, Julie Gralow, MD, chief medical officer and executive vice president of ASCO, told this news organization that she thinks the take-home message is that there is “clearly a population of early-stage breast cancer [patients] who after lumpectomy do not benefit from radiation.”
“I think where there will be discussion will be what is the optimal way of identifying that group,” she said, noting that in this study the patients were screened for Ki67, a marker of proliferation.
Testing for Ki67 is not the standard of care, Dr. Gralow pointed out, and there is also a problem with reproducibility since “every lab does it somewhat differently, because it is not a standard pathology approach.”
There are now many unanswered questions, she noted. “Do we need that central testing of Ki67? Do we need to develop guidelines for how to do this? Is this better than if you’ve already run an Oncotype or a MammaPrint test to see if the patient needs chemo, then would that suffice? That is where the discussion will be. We can reduce the number of patients who need radiation without an increase in local regional recurrence.”
In terms of clinical practice, Dr. Gralow explained that there are already some data supporting the omission of radiation therapy in an older population with ER-positive small low-grade tumors, and this has become a standard clinical practice. “It’s not based on solid data, but based on an accumulation of retrospective analyses,” she said. “So we have already been doing it for an older population. This would bring down the age group, and it would better define it, and test it prospectively.”
Limitations to note
Also commenting on the study, Deborah Axelrod, MD, director of clinical breast surgery at New York University Langone’s Perlmutter Cancer Center, explained that, in the last decade, knowledge about the behavior of breast cancers based on molecular subtyping has greatly increased. “Results of studies such as this have given us information on which cancers need more treatment and for which cancers we can de-escalate treatment,” she said. “Refining this more, it’s about reducing the morbidity and improving quality of life without compromising the oncological outcome.”
She noted that a big strength of this LUMINA study is that it is prospective and multicenter. “It has been supported by other past studies as well and will define for which patients with newly treated breast cancers can we omit radiation, which has been the standard of care,” said Dr. Axelrod. “It is based on the age and biology of breast cancer in defining which patient can forgo radiation and showed a low risk of recurrence in a specific population of women with a favorable breast cancer profile”
There were limitations to the study. “There is a 5-year follow-up and local recurrence for ER-positive cancers continues to rise after 5 years, so longer-term follow-up will be important,” she said. Also, she pointed out that it is a single-arm study so there is no radiation therapy comparison arm.
Other limitations were that the patients were older with smaller tumors, and all were committed to 5 years of endocrine therapy, although compliance with that has not been reported. There may be some older patients who prefer radiation therapy, especially a week of accelerated partial breast irradiation, rather than commit to 5 years of endocrine therapy as mandated in this study.
“Overall, the takeaway message for patients is that the omission of radiation therapy should be considered an option for older women with localized breast cancer with favorable features who receive endocrine therapies,” said Dr. Axelrod.
LUMINA was sponsored by the Canadian Breast Cancer Foundation and the Canadian Cancer Society. Dr. Whelan has reported research funding from Exact Sciences (Inst). Dr. Axelrod and Dr. Anderson reported no disclosures. Dr. Gralow reported relationships with Genentech, AstraZeneca, Hexal, Puma BioTechnology, Roche, Novartis, Seagen, and Genomic Health.

The women in this trial who skipped radiotherapy, and were treated with breast-conserving surgery followed by endocrine therapy, had an overall survival rate of 97.2%. The local recurrence rate was 2.3%, which was the study’s primary endpoint.
“Women 55 and over, with low-grade luminal A-type breast cancer, following breast conserving surgery and treated with endocrine therapy alone, had a very low rate of local recurrence at 5 years,” commented lead author Timothy Joseph Whelan, MD.
“The prospective and multicenter nature of this study supports that these patients are candidates for the omission of radiotherapy,” said Dr. Whelan, oncology professor and Canada Research Chair in Breast Cancer Research at McMaster University and a radiation oncologist at the Juravinski Cancer Centre, both in Hamilton, Ont.
“Over 300,000 [people] are diagnosed with invasive breast cancer in North America annually, the majority in the United States,” said Dr. Whelan. “We estimate that these results could apply to 10%-15% of them, so about 30,000-40,000 women per year who could avoid the morbidity, the cost, and inconvenience of radiotherapy.”
The results were presented at the annual meeting of the American Society of Clinical Oncology.

If nuclear disaster strikes, U.S. hematologists stand ready
For many Americans – especially those too young to know much about the Cold War or Hiroshima – Russia’s invasion of Ukraine might mark the first time they’ve truly considered the dangers of nuclear weapons. But dozens of hematologists in the United States already know the drill and have placed themselves on the front lines. These physicians stand prepared to treat patients exposed to radiation caused by nuclear accidents or attacks on U.S. soil.
They work nationwide at 74 medical centers that make up the Radiation Injury Treatment Network, ready to manage cases of acute radiation syndrome (ARS) during disasters. While RITN keeps a low profile, it’s been in the news lately amid anxieties about the Ukraine conflict, nuclear plant accidents, and the potential launching of nuclear weapons by foreign adversaries.
“The Radiation Injury Treatment Network helps plan responses for disaster scenarios where a person’s cells would be damaged after having been exposed to ionizing radiation,” program director Cullen Case Jr., MPA, said in an interview.
A U.S. Army veteran who took part in hurricane response early in his career, Mr. Case now oversees preparedness activities among all RITN hospitals, blood donor centers, and cord blood banks, in readiness for a mass casualty radiological incident. He also serves as a senior manager of the National Marrow Donor Program/Be a Match Marrow Registry.
Intense preparation for nuclear attacks or accidents is necessary, Mr. Case said, despite the doomsday scenarios disseminated on television shows and movies.
“The most frequent misconception we hear is that a nuclear disaster will encompass the whole world and be so complete that preparedness isn’t useful. However, many planning scenarios include smaller-scale incidents where survivors will need prompt and expert care,” he said.
In the wake of 9/11, the National Marrow Donor Program and the American Society for Blood and Marrow Transplantation established the RITN in 2006, with a mission to prepare for nuclear disaster and help manage the response if one occurs.
“The widespread availability of radioactive material has made future exposure events, accidental or intentional, nearly inevitable,” RITN leaders warned in a 2008 report. “Hematologists, oncologists, and HSCT [hematopoietic stem cell transplantation] physicians are uniquely suited to care for victims of radiation exposure, creating a collective responsibility to prepare for a variety of contingencies.”
RITN doesn’t just train physicians, Mr. Case noted. All medical centers within the RITN are required to conduct an annual tabletop exercise where a radiation disaster scenario and a set of discussion questions are presented to the team.
Hematologists specially equipped to treat radiation injuries
Why are hematologists involved in treating people exposed to dangerously high levels of radiation? The answer has to do with how radiation harms the body, said Dr. Ann A. Jakubowski, a hematologist/oncologist and transplant physician at Memorial Sloan Kettering Cancer Center, New York, who serves as a medical director for RITN.
“One of the most common toxicities from radiation exposure and a major player in acute radiation syndrome is hematologic toxicity– damage to the bone marrow by the radiation, with a resultant decrease in peripheral blood counts,” she said in an interview. “This is similar to what is often seen in the treatment of cancers with radiation and/or chemotherapy.”
In cases of severe and nonreversible radiation damage to the bone marrow, Dr. Jakubowski noted, “patients can be considered for a stem cell transplant to provide new healthy cells to repopulate the bone marrow, which provides recovery of peripheral blood counts. Hematologist/oncologists are the physicians who manage stem cell transplants.”
The crucial role of hematologists in radiation injuries is not new. In fact, these physicians have been closely intertwined with nuclear research since the dawn of the atomic age. The work of developing atomic bombs also led investigators to an understanding of the structure and processes of hematopoiesis and helped them to identify hematopoietic stem cells and prove their existence in humans.
Disaster response poses multiple challenges
As noted in a recent article in ASH Clinical News, the challenges of treating radiation injuries would be intense, especially in the event of a nuclear accident or attack that affects a wide area. For starters, how quickly can medical professionals be mobilized, and will there be enough physicians comfortable treating patients? Fortunately, irradiated patients should not pose a direct risk to medical professionals who treat them.
“The expectation is that the patients will all be decontaminated,” said Nelson Chao, MD, MBA, one of the founders of RITN and a hematologist/oncologist and transplant physician at Duke University, Durham, N.C.
Dr. Jakubowski questions whether there will be adequate resources to handle the influx of patients who need more intensive treatment, as well as outpatients who “received lower doses of radiation and may experience a period of low blood counts but are expected to eventually recover blood counts.”
And if many people are injured, Dr. Chao asks, how will physicians “adopt altered standards of care to treat large numbers of patients?”
There will also be a need for physicians who aren’t hematologists, Dr. Jakubowski said. “There may be many victims who have both radiation exposure and traumatic or burn injuries, which need to be addressed first, before the hematologist can start addressing the consequences of ARS. Traumatic and burn injuries will require surgical resources.”
In addition, ARS affects the gastrointestinal track and central nervous system/cardiovascular, and it has multiple stages, she noted.
“Although we have methods of supporting the hematopoietic system – transfusions and growth factors – and even replacing it with a stem cell transplant, this will not necessarily fix the badly damaged other organs, Dr. Jakubowski said. “Also, not all radioactive isotopes are equal in their effects, nor are the various types of radiation exposure.”
Training goes beyond transplants and drugs
RITN offers individual hematologists specialized education about treating radiation injuries through annual exercises, modules, and “just-in-time” training.
For example, the RITN webpage devoted to triage includes guidelines for transferring radiation injury patients, triage guidelines for cytokine administration in cases of ARS, an exposure and symptom triage tool, and more. The treatment page includes details about subjects such as when human leukocyte antigen typing of casualties is appropriate and how to keep yourself safe while treating patients.
Another focus is teaching hematologists to react quickly in disasters, Mr. Case said. “The vast majority of hematologists have little to no experience in responding to disasters and making decisions with imperfect or incomplete information, as emergency medicine practitioners must do regularly.”
“Some of the RITN tabletop exercises present physicians and advanced practitioners with an incomplete set of patient information and ask physicians to then determine and prioritize their care,” Mr. Case said. “The resulting discussions help to lay the groundwork for being able to shift to the crisis standards of care mindset that would be necessary during a radiological disaster.”
Here’s how hematologists can get involved
If you want to help improve the nation’s response to radiation injuries, Mr. Case suggests checking RITN’s list of participating hospitals. If your facility is already part of this network, he said, contact its bone marrow transplant unit for more information.
In such cases, Dr. Jakubowski suggests that you “consider periodically giving a presentation to staff on the basics of radiation injury and the center’s role in RITN.” And if you’re not part of RITN, she said, consider contacting the network about becoming a member.
Hematologists, Mr. Case said, can also take advantage of RITN’s free short overview courses, review the RITN Treatment Guidelines, or watch short videos on the RITN’s YouTube channel.
He highlighted the Radiation Emergency Medical Management website administered by the Department of Health & Human Services, the Center for Disease Control’s radiation emergencies webpage, and the Department of Energy’s Radiation Emergency Assistance Center/Training Site.
For many Americans – especially those too young to know much about the Cold War or Hiroshima – Russia’s invasion of Ukraine might mark the first time they’ve truly considered the dangers of nuclear weapons.

“Although we have methods of supporting the hematopoietic system – transfusions and growth factors – and even replacing it with a stem cell transplant, this will not necessarily fix the badly damaged other organs, Dr. Jakubowski said. “Also, not all radioactive isotopes are equal in their effects, nor are the various types of radiation exposure.”
Training goes beyond transplants and drugs
RITN offers individual hematologists specialized education about treating radiation injuries through annual exercises, modules, and “just-in-time” training.
For example, the RITN webpage devoted to triage includes guidelines for transferring radiation injury patients, triage guidelines for cytokine administration in cases of ARS, an exposure and symptom triage tool, and more. The treatment page includes details about subjects such as when human leukocyte antigen typing of casualties is appropriate and how to keep yourself safe while treating patients.
Another focus is teaching hematologists to react quickly in disasters, Mr. Case said. “The vast majority of hematologists have little to no experience in responding to disasters and making decisions with imperfect or incomplete information, as emergency medicine practitioners must do regularly.”
“Some of the RITN tabletop exercises present physicians and advanced practitioners with an incomplete set of patient information and ask physicians to then determine and prioritize their care,” Mr. Case said. “The resulting discussions help to lay the groundwork for being able to shift to the crisis standards of care mindset that would be necessary during a radiological disaster.”
Here’s how hematologists can get involved
If you want to help improve the nation’s response to radiation injuries, Mr. Case suggests checking RITN’s list of participating hospitals. If your facility is already part of this network, he said, contact its bone marrow transplant unit for more information.
In such cases, Dr. Jakubowski suggests that you “consider periodically giving a presentation to staff on the basics of radiation injury and the center’s role in RITN.” And if you’re not part of RITN, she said, consider contacting the network about becoming a member.
Hematologists, Mr. Case said, can also take advantage of RITN’s free short overview courses, review the RITN Treatment Guidelines, or watch short videos on the RITN’s YouTube channel.

For many Americans – especially those too young to know much about the Cold War or Hiroshima – Russia’s invasion of Ukraine might mark the first time they’ve truly considered the dangers of nuclear weapons. But dozens of hematologists in the United States already know the drill and have placed themselves on the front lines. These physicians stand prepared to treat patients exposed to radiation caused by nuclear accidents or attacks on U.S. soil.
They work nationwide at 74 medical centers that make up the Radiation Injury Treatment Network, ready to manage cases of acute radiation syndrome (ARS) during disasters. While RITN keeps a low profile, it’s been in the news lately amid anxieties about the Ukraine conflict, nuclear plant accidents, and the potential launching of nuclear weapons by foreign adversaries.
“The Radiation Injury Treatment Network helps plan responses for disaster scenarios where a person’s cells would be damaged after having been exposed to ionizing radiation,” program director Cullen Case Jr., MPA, said in an interview.
A U.S. Army veteran who took part in hurricane response early in his career, Mr. Case now oversees preparedness activities among all RITN hospitals, blood donor centers, and cord blood banks, in readiness for a mass casualty radiological incident. He also serves as a senior manager of the National Marrow Donor Program/Be a Match Marrow Registry.
Intense preparation for nuclear attacks or accidents is necessary, Mr. Case said, despite the doomsday scenarios disseminated on television shows and movies.
“The most frequent misconception we hear is that a nuclear disaster will encompass the whole world and be so complete that preparedness isn’t useful. However, many planning scenarios include smaller-scale incidents where survivors will need prompt and expert care,” he said.
In the wake of 9/11, the National Marrow Donor Program and the American Society for Blood and Marrow Transplantation established the RITN in 2006, with a mission to prepare for nuclear disaster and help manage the response if one occurs.
“The widespread availability of radioactive material has made future exposure events, accidental or intentional, nearly inevitable,” RITN leaders warned in a 2008 report. “Hematologists, oncologists, and HSCT [hematopoietic stem cell transplantation] physicians are uniquely suited to care for victims of radiation exposure, creating a collective responsibility to prepare for a variety of contingencies.”
RITN doesn’t just train physicians, Mr. Case noted. All medical centers within the RITN are required to conduct an annual tabletop exercise where a radiation disaster scenario and a set of discussion questions are presented to the team.
Hematologists specially equipped to treat radiation injuries
Why are hematologists involved in treating people exposed to dangerously high levels of radiation? The answer has to do with how radiation harms the body, said Dr. Ann A. Jakubowski, a hematologist/oncologist and transplant physician at Memorial Sloan Kettering Cancer Center, New York, who serves as a medical director for RITN.
“One of the most common toxicities from radiation exposure and a major player in acute radiation syndrome is hematologic toxicity– damage to the bone marrow by the radiation, with a resultant decrease in peripheral blood counts,” she said in an interview. “This is similar to what is often seen in the treatment of cancers with radiation and/or chemotherapy.”
In cases of severe and nonreversible radiation damage to the bone marrow, Dr. Jakubowski noted, “patients can be considered for a stem cell transplant to provide new healthy cells to repopulate the bone marrow, which provides recovery of peripheral blood counts. Hematologist/oncologists are the physicians who manage stem cell transplants.”
The crucial role of hematologists in radiation injuries is not new. In fact, these physicians have been closely intertwined with nuclear research since the dawn of the atomic age. The work of developing atomic bombs also led investigators to an understanding of the structure and processes of hematopoiesis and helped them to identify hematopoietic stem cells and prove their existence in humans.
Disaster response poses multiple challenges
As noted in a recent article in ASH Clinical News, the challenges of treating radiation injuries would be intense, especially in the event of a nuclear accident or attack that affects a wide area. For starters, how quickly can medical professionals be mobilized, and will there be enough physicians comfortable treating patients? Fortunately, irradiated patients should not pose a direct risk to medical professionals who treat them.
“The expectation is that the patients will all be decontaminated,” said Nelson Chao, MD, MBA, one of the founders of RITN and a hematologist/oncologist and transplant physician at Duke University, Durham, N.C.
Dr. Jakubowski questions whether there will be adequate resources to handle the influx of patients who need more intensive treatment, as well as outpatients who “received lower doses of radiation and may experience a period of low blood counts but are expected to eventually recover blood counts.”
And if many people are injured, Dr. Chao asks, how will physicians “adopt altered standards of care to treat large numbers of patients?”
There will also be a need for physicians who aren’t hematologists, Dr. Jakubowski said. “There may be many victims who have both radiation exposure and traumatic or burn injuries, which need to be addressed first, before the hematologist can start addressing the consequences of ARS. Traumatic and burn injuries will require surgical resources.”
In addition, ARS affects the gastrointestinal track and central nervous system/cardiovascular, and it has multiple stages, she noted.
“Although we have methods of supporting the hematopoietic system – transfusions and growth factors – and even replacing it with a stem cell transplant, this will not necessarily fix the badly damaged other organs, Dr. Jakubowski said. “Also, not all radioactive isotopes are equal in their effects, nor are the various types of radiation exposure.”
