A new strategy proposed by an international team of experts would limit the use of the prostate-specific antigen (PSA) test for screening tor prostate cancer to men who are younger than 70 years and who are at high risk or symptomatic.

This would reduce potential harms from overdiagnosis and overtreatment, the risk for which is high with the on-demand screening that is the current standard of care in most wealthy nations.

In a paper published online in The BMJ, the panel recommends instead a comprehensive nationwide program that would base PSA testing on individual patient risk and direct those with abnormal results to a managed system of imaging, targeted biopsy only if indicated, and subsequent active monitoring or treatment for those with more aggressive disease features.

Alternatively, government health programs could actively discourage widespread PSA testing and implement policies that would effectively limit PSA-based screening only to men with urologic symptoms warranting further exploration, said the authors, led by Andrew Vickers, PhD, a research epidemiologist at Memorial Sloan Kettering Cancer Center in New York.

“Although we believe that early detection of prostate cancer should involve shared decision making, the current approach of determining testing by shared decision making has resulted in the worst possible practical outcome of high levels of PSA testing and medical harm, with minimal benefit and inequity,” they wrote.

“To make better use of PSA testing, policy makers should choose between a comprehensive, risk adapted approach that is specifically designed to reduce overdiagnosis and overtreatment, or restricting PSA testing to people referred to urologists with symptoms. That choice will need to take into account wider patient and public perspective, as well as health economic concerns,” they continued.
 

Inappropriate testing

Since the Food and Drug Administration approved the first PSA screen in 1986 as a means for monitoring disease progression in patients being treated for prostate cancer, the test has remained controversial, embraced by some for its presumed ability to spot early prostate cancer but scorned by others for its equivocal results in patients with benign prostate pathology and for its potential to lead to overdiagnosis and overtreatment of low-grade disease in men who would otherwise be likely to die of other causes.

Currently, only Lithuania and Kazakhstan have government-supported population-based screening programs for prostate cancer. In contrast, the United States, United Kingdom, and other high-income countries have opted not to implement nationwide prostate cancer screening but allow so-called “informed choice testing,” in which men can receiving PSA screening after discussion with a primary care physician, urologist, or other specialist.

The U.S. Preventive Services Task Force recommends that for men aged 55-69 years, the decision to undergo PSA testing should be an individual one, based on an understanding of the risks and benefits. For men aged 70 or older, the task force flatly states, “Do not screen for prostate cancer.”

But as Dr. Vickers and colleagues noted, “high income countries that have made PSA testing available to men who request it after shared decision making with their physician now have a high prevalence of PSA testing with an inappropriate age distribution.”

For example, they pointed out that in the United Kingdom, men in their 80s are twice as likely as are men in their 50s to get a PSA test, even though men in the older age group are far less likely to have benefit and far more likely to experience harm from treatment. Similarly, in France, nearly one-third of men over 40 get an annual PSA test, with the highest incidence of PSA testing in men over age 70. There are also high rates of PSA testing in men over 70 in Italy, Germany, and Ireland.

“A key problem is that, in current routine care – and despite guidelines to the contrary – most men with an abnormal PSA result have prostate biopsy, even though only a minority will have aggressive prostate cancer,” Dr. Vickers and colleagues wrote. “Furthermore, most men with biopsy-detected cancers have either surgery or radiotherapy (with or without androgen deprivation therapy) even if they have low-risk tumors that are unlikely to cause cancer related morbidity or mortality.”

In addition, informed-choice PSA testing may lead to health inequities, the team noted, citing data from the United States, Canada, and Switzerland showing an inverse association between income and education and the likelihood of PSA testing. Also, in the United States and Canada, men from ethnic minority groups are less likely to have PSA testing.
 

Comprehensive risk-based program

Dr. Vickers and colleagues proposed that a “comprehensive, risk-based prostate cancer detection program based on best evidence on how to use PSA testing and manage subsequent diagnostic follow-up and treatment could reduce overdiagnosis and overtreatment.

“Such a program would restrict testing to men (and those not identifying as male but who have a prostate) aged 50-70, define testing intervals by PSA levels, stop testing early for those with lower PSA, offer biopsy only to those identified as at high risk of aggressive disease after a secondary test (such as magnetic resonance imaging [MRI] or blood markers), and limit treatment to those with high Gleason grade tumors,” they wrote.
 

‘Sound analysis’

Two experts who were not involved with the BMJ paper applaud the suggestions made in comments posted on the U.K. Science Media Centre.

Benjamin W. Lamb, MBBS, MA, PhD, a consultant urologist and surgeon at Barts Health NHS Trust in London, said the analysis conducted by the panel “is sound as there are known benefits from risk-adapted comprehensive screening trials in men aged 50-70, but discordance with current practice, meaning benefits and harms are not those seen in trials.”

However, he also said that the strategies proposed by the authors would be unlikely to prevent older, well-informed men from requesting and getting a PSA test.

“In my view, the emphasis should be on engaging younger and at-risk men rather than restricting access for older men,” he said, noting that the alternative proposal of restricting PSA testing “in my view, is not feasible.”

Nick James, MBBS, PhD, professor of prostate and bladder cancer research at the Institute of Cancer Research, London, and consultant oncologist at the Royal Marsden NHS Foundation Trust, said, “I agree with the authors and strongly support the implementation of a risk-based approach to PSA testing at a national level.

“There is an urgent need for a more equitable and targeted screening strategy, which could help address existing health disparities,” Dr. James said. “Currently, individuals from economically disadvantaged backgrounds are less likely to undergo PSA testing. Men in their 50s or younger, who may stand to benefit more from these tests, are also less likely to receive PSA tests compared to older men who benefit less. Linked to better diagnostic pathways with MRI, already standard in the UK, potential harms from overdiagnosis and overtreatment can be mitigated.”

The analysis was supported in part by the U.S. National Institutes of Health/National Cancer Institute with a Cancer Center Support Grant to Memorial Sloan Kettering Cancer Center, and NIH grants to coauthors. Dr. Vickers is a coinventor of the 4Kscore, a commercial test for predicting prostate biopsy outcome. He receives royalties from sales of the test and owns stock options in OPKO, which offers the test. Coauthor James W.F. Catto, PhD, disclosed ties to Astellas, AstraZeneca, BMS, Ferring, Gilead, Janssen, MSD, Nucleix, Photocure, QED Therapeutics, and Roche.

The number of cancer survivors who report functional limitation has more than doubled in 20 years, according to a research letter published in JAMA Oncology.

Vishal Patel, BS, a student at the Dell Medical School at The University of Texas at Austin, and colleagues identified 51,258 cancer survivors from the National Health Interview Survey, representing a weighted population of approximately 178.8 million from 1999 to 2018.

Most survivors were women (60.2%) and were at least 65 years old (55.4%). In 1999, 3.6 million weighted survivors reported functional limitation. In 2018, the number increased to 8.2 million, a 2.25-fold increase.

The number of survivors who reported no limitations also increased, but not by as much. That group grew 1.34-fold during the study period.

For context, “the 70% prevalence of functional limitation among survivors in 2018 is nearly twice that of the general population,” the authors wrote.
 

Patients surveyed on function

Functional limitation was defined as “self-reported difficulty performing any of 12 routine physical or social activities without assistance.” Examples of the activities included difficulty sitting for more than 2 hours, difficulty participating in social activities or difficulty pushing or pulling an object the size of a living room chair.

Over the 2 decades analyzed, the adjusted prevalence of functional limitation was highest among survivors of pancreatic cancer (80.3%) and lung cancer (76.5%). Prevalence was lowest for survivors of melanoma (62.2%), breast (61.8%) and prostate (59.5%) cancers.
 

Not just a result of living longer

Mr. Patel told this publication that one assumption people might make when they read these results is that people are just living longer with cancer and losing functional ability accordingly.

“But, in fact, we found that the youngest [– those less than 65 years–] actually contributed to this trend more than the oldest people, which means it’s not just [happening], because people are getting older,” he said.

Hispanic and Black individuals had disproportionately higher increases in functional limitation; percentage point increases over the 2 decades were 19.5 for Black people, 25.1 for Hispanic people and 12.5 for White people. There may be a couple of reasons for that, Mr. Patel noted.

Those who are Black or Hispanic tend to have less access to cancer survivorship care for reasons including insurance status and historic health care inequities, he noted.

“The other potential reason is that they have had less access to cancer care historically. And if, 20 years ago Black and Hispanic individuals didn’t have access to some chemotherapies, and now they do, maybe it’s the increased access to care that’s causing these functional limitations. Because chemotherapy can sometimes be very toxic. It may be sort of a catch-up toxicity,” he said.
 

Quality of life beyond survivorship

Mr. Patel said the results seem to call for building on improved survival rates by tracking and improving function.

“It’s good to celebrate that there are more survivors. But now that we can keep people alive longer, maybe we can shift gears to improving their quality of life,” he said.

The more-than-doubling of functional limitations over 2 decades “is a very sobering trend,” he noted, while pointing out that the functional limitations applied to 8 million people in the United States – people whose needs are not being met.

There’s no sign of the trend stopping, he continued. “We saw no downward trend, only an upward trend.”

Increasingly, including functionality as an endpoint in cancer trials, in addition to improvements in mortality, is one place to start, he added.

“Our findings suggest an urgent need for care teams to understand and address function, for researchers to evaluate function as a core outcome in trials, and for health systems and policy makers to reimagine survivorship care, recognizing the burden of cancer and its treatment on physical, psychosocial, and cognitive function,” the authors wrote in their paper. Limitations of the study include the potential for recall bias, lack of cancer staging or treatment information, and the subjective perception of function.

A coauthor reported personal fees from Astellas, AstraZeneca, AAA, Blue Earth, Janssen, Lantheus, Myovant, Myriad Genetics, Novartis, Telix, and Sanofi, as well as grants from Pfizer and Bayer during the conduct of the study. No other disclosures were reported.

Communities with easy access to fast food were 77% more likely to have high levels of obesity-related cancer mortality, based on data from a new cross-sectional study of more than 3,000 communities.

Although increased healthy eating has been associated with reduced risk of obesity and with reduced cancer incidence and mortality, access to healthier eating remains a challenge in communities with less access to grocery stores and healthy food options (food deserts) and/or easy access to convenience stores and fast food (food swamps), Malcolm Seth Bevel, PhD, of the Medical College of Georgia, Augusta, and colleagues, wrote in their paper, published in JAMA Oncology.

In addition, data on the association between food deserts and swamps and obesity-related cancer mortality are limited, they said.

“We felt that the study was important given the fact that obesity is an epidemic in the United States, and multiple factors contribute to obesity, especially adverse food environments,” Dr. Bevel said in an interview. “Also, I lived in these areas my whole life, and saw how it affected underserved populations. There was a story that needed to be told, so we’re telling it,” he said in an interview.

In a study, the researchers analyzed food access and cancer mortality data from 3,038 counties across the United States. The food access data came from the U.S. Department of Agriculture Food Environment Atlas (FEA) for the years 2012, 2014, 2015, 2017, and 2020. Data on obesity-related cancer mortality came from the Centers for Disease Control and Prevention for the years from 2010 to 2020.

Food desert scores were calculated through data from the FEA, and food swamp scores were based on the ratio of fast-food restaurants and convenience stores to grocery stores and farmers markets in a modification of the Retail Food Environment Index score.

The researchers used an age-adjusted, multiple regression model to determine the association between food desert and food swamp scores and obesity-related cancer mortality rates. Higher food swamp and food desert scores (defined as 20.0 to 58.0 or higher) were used to classify counties as having fewer healthy food resources. The primary outcome was obesity-related cancer mortality, defined as high or low (71.8 or higher per 100,000 individuals and less than 71.8 per 100,000 individuals, respectively).

Overall, high rates of obesity-related cancer mortality were 77% more likely in the counties that met the criteria for high food swamp scores (adjusted odds ratio 1.77). In addition, researchers found a positive dose-response relationship among three levels of both food desert scores and food swamp scores and obesity-related cancer mortality.

A total of 758 counties had obesity-related cancer mortality rates in the highest quartile. Compared to counties with low rates of obesity-related cancer mortality, counties with high rates of obesity-related cancer mortality also had a higher percentage of non-Hispanic Black residents (3.26% vs. 1.77%), higher percentage of adults older than 65 years (15.71% vs. 15.40%), higher rates of adult obesity (33.0% vs. 32.10%), and higher rates of adult diabetes (12.50% vs. 10.70%).

Possible explanations for the results include the lack of interest in grocery stores in neighborhoods with a population with a lower socioeconomic status, which can create a food desert, the researchers wrote in their discussion. “Coupled with the increasing growth rate of fast-food restaurants in recent years and the intentional advertisement of unhealthy foods in urban neighborhoods with [people of lower income], the food desert may transform into a food swamp,” they said.

The findings were limited by several factors including the study design, which did not allow for showing a causal association of food deserts and food swamps with obesity-related cancer mortality, the researchers noted. Other limitations included the use of groups rather than individuals, the potential misclassification of food stores, and the use of county-level data on race, ethnicity, and income, they wrote.

The results indicate that “food swamps appear to be a growing epidemic across the U.S., likely because of systemic issues, and should draw concern and conversation from local and state officials,” the researchers concluded.
 

Community-level investments can benefit individual health

Dr. Bevel said he was not surprised by the findings, as he has seen firsthand the lack of healthy food options and growth of unhealthy food options, especially for certain populations in certain communities. “Typically, these are people who have lower socioeconomic status, primarily non-Hispanic Black or African American or Hispanic American,” he said “I have watched people have to choose between getting fruits/vegetables versus their medications or running to fast food places to feed their families. What is truly surprising is that we’re not talking about people’s lived environment enough for my taste,” he said.  

“I hope that our data and results can inform local and state policymakers to truly invest in all communities, such as funding for community gardens, and realize that adverse food environments, including the barriers in navigating these environments, have significant consequences on real people,” said Dr. Bevel. “Also, I hope that the results can help clinicians realize that a patient’s lived environment can truly affect their obesity and/or obesity-related cancer status; being cognizant of that is the first step in holistic, comprehensive care,” he said. 

“One role that oncologists might be able to play in improving patients’ access to healthier food is to create and/or implement healthy lifestyle programs with gardening components to combat the poorest food environments that their patients likely reside in,” said Dr. Bevel. Clinicians also could consider the innovative approach of “food prescriptions” to help reduce the effects of deprived, built environments, he noted.

Looking ahead, next steps for research include determining the severity of association between food swamps and obesity-related cancer by varying factors such as cancer type, and examining any potential racial disparities between people living in these environments and obesity-related cancer, Dr. Bevel added.
 

Data provide foundation for multilevel interventions

The current study findings “raise a clarion call to elevate the discussion on food availability and access to ensure an equitable emphasis on both the importance of lifestyle factors and the upstream structural, economic, and environmental contexts that shape these behaviors at the individual level,” Karriem S. Watson, DHSc, MS, MPH, of the National Institutes of Health, Bethesda, Md., and Angela Odoms-Young, PhD, of Cornell University, Ithaca, N.Y., wrote in an accompanying editorial.

The findings provide a foundation for studies of obesity-related cancer outcomes that take the community environment into consideration, they added.

The causes of both obesity and cancer are complex, and the study findings suggest that the links between unhealthy food environments and obesity-related cancer may go beyond dietary consumption alone and extend to social and psychological factors, the editorialists noted.

“Whether dealing with the lack of access to healthy foods or an overabundance of unhealthy food, there is a critical need to develop additional research that explores the associations between obesity-related cancer mortality and food inequities,” they concluded.

The study received no outside funding. The researchers and the editorialists had no financial conflicts to disclose.

Communities with easy access to fast food were 77% more likely to have high levels of obesity-related cancer mortality, based on data from a new cross-sectional study of more than 3,000 communities.

Although increased healthy eating has been associated with reduced risk of obesity and with reduced cancer incidence and mortality, access to healthier eating remains a challenge in communities with less access to grocery stores and healthy food options (food deserts) and/or easy access to convenience stores and fast food (food swamps), Malcolm Seth Bevel, PhD, of the Medical College of Georgia, Augusta, and colleagues, wrote in their paper, published in JAMA Oncology.

In addition, data on the association between food deserts and swamps and obesity-related cancer mortality are limited, they said.

SAN DIEGO – Primary care providers can draw from a wide range of diets to give patients evidence-based advice on how to lose weight, prevent diabetes, and achieve other health goals, according to a speaker at the annual meeting of the American College of Physicians.

“Evidence from studies can help clinicians and their patients develop a successful dietary management plan and achieve optimal health,” said internist Michelle Hauser, MD, clinical associate professor at Stanford (Calif.) University. She also discussed evidence-based techniques to support patients in maintaining dietary modifications.
 

Predominantly plant‐based diets

Popular predominantly plant‐based diets include a Mediterranean diet, healthy vegetarian diet, predominantly whole-food plant‐based (WFPB) diet, and a dietary approach to stop hypertension (DASH).

The DASH diet was originally designed to help patients manage their blood pressure, but evidence suggests that it also can help adults with obesity lose weight. In contrast to the DASH diet, the Mediterranean diet is not low-fat and not very restrictive. Yet the evidence suggests that the Mediterranean diet is not only helpful for losing weight but also can reduce the risk of various chronic diseases, including obesity, type 2 diabetes, cardiovascular disease (CVD), and cancer, Dr. Hauser said. In addition, data suggest that the Mediterranean diet may reduce the risk of all-cause mortality and lower the levels of cholesterol.

“I like to highlight all these protective effects to my patients, because even if their goal is to lose weight, knowing that hard work pays off in additional ways can keep them motivated,” Dr. Hauser stated.

A healthy vegetarian diet and a WFPB diet are similar, and both are helpful in weight loss and management of total cholesterol and LDL‐C levels. Furthermore, healthy vegetarian and WFPB diets may reduce the risk of type 2 diabetes, CVD, and some cancers. Cohort study data suggest that progressively more vegetarian diets are associated with lower BMIs.

“My interpretation of these data is that predominantly plant-based diets rich in whole foods are healthful and can be done in a way that is sustainable for most,” said Dr. Hauser. However, this generally requires a lot of support at the outset to address gaps in knowledge, skills, and other potential barriers.

For example, she referred one obese patient at risk of diabetes and cardiovascular disease to a registered dietitian to develop a dietary plan. The patient also attended a behavioral medicine weight management program to learn strategies such as using smaller plates, and his family attended a healthy cooking class together to improve meal planning and cooking skills.
 

Time‐restricted feeding

There are numerous variations of time-restricted feeding, commonly referred to as intermittent fasting, but the principles are similar – limiting food intake to a specific window of time each day or week.

Although some studies have shown that time-restricted feeding may help patients reduce adiposity and improve lipid markers, most studies comparing time-restricted feeding to a calorie-restricted diet have shown little to no difference in weight-related outcomes, Dr. Hauser said.

These data suggest that time-restricted feeding may help patients with weight loss only if time restriction helps them reduce calorie intake. She also warned that time-restrictive feeding might cause late-night cravings and might not be helpful in individuals prone to food cravings.
 

Low‐carbohydrate and ketogenic diets

Losing muscle mass can prevent some people from dieting, but evidence suggests that a high-fat, very low-carbohydrate diet – also called a ketogenic diet – may help patients reduce weight and fat mass while preserving fat‐free mass, Dr. Hauser said.

The evidence regarding the usefulness of a low-carbohydrate (non-keto) diet is less clear because most studies compared it to a low-fat diet, and these two diets might lead to a similar extent of weight loss.
 

Rating the level of scientific evidence behind different diet options

Nutrition studies do no provide the same level of evidence as drug studies, said Dr. Hauser, because it is easier to conduct a randomized controlled trial of a drug versus placebo. Diets have many more variables, and it also takes much longer to observe most outcomes of a dietary change.

In addition, clinical trials of dietary interventions are typically short and focus on disease markers such as serum lipids and hemoglobin A1c levels. To obtain reliable information on the usefulness of a diet, researchers need to collect detailed health and lifestyle information from hundreds of thousands of people over several decades, which is not always feasible. “This is why meta-analyses of pooled dietary study data are more likely to yield dependable findings,” she noted.
 

Getting to know patients is essential to help them maintain diet modifications

When developing a diet plan for a patient, it is important to consider the sustainability of a dietary pattern. “The benefits of any healthy dietary change will only last as long as they can be maintained,” said Dr. Hauser. “Counseling someone on choosing an appropriate long-term dietary pattern requires getting to know them – taste preferences, food traditions, barriers, facilitators, food access, and time and cost restrictions.”

In an interview after the session, David Bittleman, MD, an internist at Veterans Affairs San Diego Health Care System, agreed that getting to know patients is essential for successfully advising them on diet.

“I always start developing a diet plan by trying to find out what [a patient’s] diet is like and what their goals are. I need to know what they are already doing in order to make suggestions about what they can do to make their diet healthier,” he said.

When asked about her approach to supporting patients in the long term, Dr. Hauser said that she recommends sequential, gradual changes. Dr. Hauser added that she suggests her patients prioritize implementing dietary changes that they are confident they can maintain.

Dr. Hauser and Dr. Bittleman report no relevant financial relationships.

When developing a diet plan for a patient, it is important to consider the sustainability of a dietary pattern. “The benefits of any healthy dietary change will only last as long as they can be maintained,” said Dr. Hauser. “Counseling someone on choosing an appropriate long-term dietary pattern requires getting to know them – taste preferences, food traditions, barriers, facilitators, food access, and time and cost restrictions.”

In an interview after the session, David Bittleman, MD, an internist at Veterans Affairs San Diego Health Care System, agreed that getting to know patients is essential for successfully advising them on diet.

“I always start developing a diet plan by trying to find out what [a patient’s] diet is like and what their goals are. I need to know what they are already doing in order to make suggestions about what they can do to make their diet healthier,” he said.

When asked about her approach to supporting patients in the long term, Dr. Hauser said that she recommends sequential, gradual changes. Dr. Hauser added that she suggests her patients prioritize implementing dietary changes that they are confident they can maintain.

Adults with cancer experienced significant reductions in pain after taking medicinal cannabis, in a study.

Physician-prescribed cannabis, particularly cannabinoids, has been shown to ease cancer-related pain in adult cancer patients, who often find inadequate pain relief from medications including opioids, Saro Aprikian, MSc, a medical student at the Royal College of Surgeons, Dublin, and colleagues, wrote in their paper.

However, real-world data on the safety and effectiveness of cannabis in the cancer population and the impact on use of other medications are lacking, the researchers said.

In the study, published in BMJ Supportive & Palliative Care, the researchers reviewed data from 358 adults with cancer who were part of a multicenter cannabis registry in Canada between May 2015 and October 2018.

The average age of the patients was 57.6 years, and 48% were men. The top three cancer diagnoses in the study population were genitorurinary, breast, and colorectal.

Pain was the most common reason for obtaining a medical cannabis prescription, cited by 72.4% of patients.

Data were collected at follow-up visits conducted every 3 months over 1 year. Pain was assessed via the Brief Pain Inventory (BPI) and revised Edmonton Symptom Assessment System (ESAS-r) questionnaires and compared to baseline values. Patients rated their pain intensity on a sliding scale of 0 (none) to 10 (worst possible). Pain relief was rated on a scale of 0% (none) to 100% (complete).

Compared to baseline scores, patients showed significant decreases at 3, 6 and 9 months for BPI worst pain (5.5 at baseline, 3.6 for 3, 6, and 9 months) average pain (4.1 at baseline, 2.4, 2.3, and 2.7 for 3, 6, and 9 months, respectively), overall pain severity (2.7 at baseline, 2.3, 2.3, and 2.4 at 3, 6, and 9 months, respectively), and pain interference with daily life (4.3 at baseline, 2.4, 2.2, and 2.4 at 3, 6, and 9 months, respectively; P less than .01 for all four pain measures).

“Pain severity as reported in the ESAS-r decreased significantly at 3-month, 6-month and 9-month follow-ups,” the researchers noted.

In addition, total medication burden based on the medication quantification scale (MQS) and morphine equivalent daily dose (MEDD) were recorded at 3, 6, 9, and 12 months. MQS scores decreased compared to baseline at 3, 6, 9, and 12 months in 10%, 23.5%, 26.2%, and 31.6% of patients, respectively. Also compared with baseline, 11.1%, 31.3%, and 14.3% of patients reported decreases in MEDD scores at 3, 6, and 9 months, respectively.

Overall, products with equal amounts of active ingredients tetrahydrocannabinol (THC) and cannabidiol (CBD) were more effective than were those with a predominance of either THC or CBD, the researchers wrote.

Medical cannabis was well-tolerated; a total of 15 moderate to severe side effects were reported by 11 patients, 13 of which were minor. The most common side effects were sleepiness and fatigue, and five patients discontinued their medical cannabis because of side effects. The two serious side effects reported during the study period – pneumonia and a cardiovascular event – were deemed unlikely related to the patients’ medicinal cannabis use.

The findings were limited by several factors, including the observational design, which prevented conclusions about causality, the researchers noted. Other limitations included the loss of many patients to follow-up and incomplete data on other prescription medications in many cases.

The results support the use of medical cannabis by cancer patients as an adjunct pain relief strategy and a way to potentially reduce the use of other medications such as opioids, the authors concluded.

The study was supported by the Canadian Consortium for the Investigation of Cannabinoids, Collège des Médecins du Québec, and the Canopy Growth Corporation. The researchers had no financial conflicts to disclose.

An old dog – nitrous oxide – can learn new tricks, managing pain in men undergoing transrectal biopsies, researchers reported at the annual meeting of the American Urological Association.

“At concentrations of less than 50%, nitrous oxide is classified as a minimal sedative, making it a promising option for many urologic outpatient procedures such as prostate biopsies,” said Heidi Rayala, MD, PhD, assistant professor of surgery at Harvard Medical School, Boston, who helped conduct the study.

Nitrous oxide is best known as a pain medication and anesthetic during dental procedures and childbirth, after trauma, and in end-of-life care.

In the new study, Dr. Rayala and her colleagues at Harvard and Beth Israel-Deaconess Medical Center, Boston, randomly assigned 128 men to self-administered nitrous oxide (SANO) or oxygen as a placebo. Patients in the SANO group had a smaller change in post-biopsy pain score (Visual Analog Scale for pain, 0.43 vs. 1.03; P = .03) and lower odds of experiencing pain during the procedure (odds ratio, 0.45; confidence interval, 0.21-0.97; P = .04).

A comparison of anxiety scores in the two groups failed to find a statistically significant difference between SANO and placebo. However, more men who received nitrous oxide said they tolerated the procedure “better than expected” (61% vs. 41%; P = 0.02), according to the researchers.

Dr. Rayala said that the researchers used the Nitrouseal system (Sedation Systems), in which the patient holds a mask to their face and works with staff to adjust the gas levels to the desired amount. The system is governed to max out at 50% nitrous oxide, ensuring “minimal sedation concentrations, so anesthesia personnel are not required,” she said.

“At levels of less than 50%, patients respond normally to verbal commands and maintain normal airway reflexes,” Dr. Rayala added. “This provides an advantage in that patients do not require the presence of anesthesia personnel.” And because the body eliminates the gas within about 5 minutes, patients do not require an escort home, she said.

This system is also self-scavenging to protect the operating urologist and other personnel from environmental exposure to nitrous oxide.

Dr. Rayala said that three patients (2.3%) found the mask uncomfortable, but in follow-up studies the clinicians have done a better job of preparing patients for the feeling of the mask, making a marked difference. Headaches and nausea are the most commonly reported complaints at concentrations above 50%.

“We did not have patients report headaches or nausea in new study (by the BIDMC group),” she said. This study has been submitted for publication.

Clinicians outside the United States have been quicker to embrace nitrous oxide for prostate procedures.

In a randomized controlled trial, researchers in Australia found no significant improvement in pain scores at 15 minutes from the use of nitrous oxide during transrectal biopsies; however, improvements were seen in patient-reported discomfort, overall experience, and willingness to undergo repeat biopsies.

Stephen McCombie, MD, a consultant at Perth Urology Clinic, Australia, who has been adapting the nitrous oxide protocol for transrectal biopsies to transperineal procedures, said that the Beth Israel study “adds to the evidence to support adjunct use of mild inhalational anesthetics and analgesics during prostate biopsies to improve the patient experience of the procedure.”

He said that the role for these agents may grow with the global trend away from transrectal prostate biopsies and toward transperineal biopsies, largely driven by increasing rates of sepsis after transrectal biopsies.

“While transperineal biopsies can be more painful then transrectal biopsies when performed under local anesthesia, perhaps due to biopsies being taken through the highly sensate perineum as opposed to above the dentate line, optimization of the technique can significantly reduce the discomfort associated with the procedure, which may be further reduced with these agents,” Dr. McCombie said.

“Studies indicate that transperineal biopsies can be more painful than the traditional transrectal biopsies,” Dr. Rayala said. “We do offer transperineal biopsies at BIDMC, and we are gearing up to repeat the SANO study” for those patients.

Dr. Rayala and Dr. McCombie have disclosed no relevant financial relationships.

A panel of independent advisers recently almost unanimously recommended to restrict a new indication for olaparib (Lynparza) alongside abiraterone (Zytiga) in patients with metastatic castration-resistant prostate cancer.

On April 28, members of the Oncologic Drugs Advisory Committee voted 11 to 1, with one abstention, that only patients whose tumors have a BRCA mutation should receive olaparib as part of the combination first-line treatment for metastatic castration-resistant prostate cancer.

Olaparib is already cleared by the Food and Drug Administration for various ovarian, breast, and pancreatic cancer indications as well as later-line use in certain more advanced prostate cancers. AstraZeneca recently applied for an additional, broad indication for the poly (ADP-ribose) polymerase (PARP) inhibitor as an initial therapy that would include patients without BRCA or homologous recombination repair (HRR) mutations.

In reviewing the application, the FDA raised concerns about this broad new indication, highlighting limitations in the key research used to justify the expanded use and highlighting how olaparib may amount to a “toxic placebo,” a phrase agency staff used in their briefing document.

Given these concerns, the FDA reviewers asked the independent ODAC panel to vote on the following question: “As FDA reviews the proposed indication for olaparib in combination with abiraterone for initial treatment of [metastatic castration-resistant prostate cancer], should the indication be restricted to patients whose tumors have a BRCA mutation?”

The ODAC panel voted 11 to 1 in favor of a restricted expansion of olaparib plus abiraterone and prednisone or prednisolone to patients whose tumors have a BRCA mutation. One member – Ravi A. Madan, MD, of the National Cancer Institute – abstained. The FDA staff asked panelists to abstain if they felt the combination treatment should not be approved for any indication.

Overall, the ODAC panel agreed with the FDA staff’s criticism of the research supporting the application: the PROpel study. The trial randomized 796 patients with previously untreated metastatic castration-resistant prostate cancer to olaparib plus abiraterone or abiraterone plus placebo. The median time for radiographic progression-free survival – the study’s primary endpoint – was nearly 25 months in the olaparib group versus 16.6 months in the placebo group.

The combination also demonstrated a 19% reduced risk of death, which was not statistically significant (hazard ratio, 0.81; P = .0544), and a median improvement of 7.4 months in the combination arm (42.1 vs. 34.7 months).

Although the study met its primary endpoint, the results were difficult to interpret given the lack of information about genetic variability in the participants’ tumors. Participants were not prospectively assessed for either BRCA or HRR status. But given the importance of BRCA status as a predictive biomarker for PARP inhibitor efficacy, “this trial design would be considered inappropriate today as the biomarker should have been prospectively evaluated,” the FDA wrote in its briefing document.

In a post hoc analysis performed by the FDA, the agency found that BRCA-positive patients accounted for most of the survival benefit of the combination, though made up only 11% of the PROpel population.

That meant the ODAC members were being asked to evaluate a drug based on “suboptimal data” resulting from a “suboptimal study design,” said Dr. Madan, who is head of the prostate cancer clinical research section in the NCI’s Center for Cancer Research.

Dr. Madan also emphasized concerns the FDA raised about the potential harms for patients whose prostate cancer was not tied to BRCA mutations. In the FDA’s briefing document, the agency said patients treated in the first-line metastatic castration-resistant prostate cancer setting generally have few symptoms at baseline. Adding olaparib among patients lacking the BRCA mutation could expose them to a drug with known side effects but minimal chance to help them.

The PROpel trial also found that patients who received olaparib and abiraterone experienced greater toxicity than those who received abiraterone. These adverse events included venous thromboembolic events, myelosuppression, requirement for blood transfusions, nausea, vomiting, and diarrhea.

Although the FDA is not compelled to follow the recommendations of its advisory committees, it often does.

AstraZeneca expressed some disappointment about the recommendation in a press release. Susan Galbraith, executive vice president of Oncology R&D at AstraZeneca, said, “while we are pleased with the recognition of the benefit of Lynparza plus abiraterone for patients with BRCA-mutated metastatic castration-resistant prostate cancer, we are disappointed with the outcome of today’s ODAC meeting. We strongly believe in the results of the PROpel trial, which demonstrated the clinically meaningful benefit for this combination in a broad population of patients regardless of biomarker status.”

One ODAC member, Jorge J. Nieva, MD, did support the expanded approval for olaparib, casting the single “no” vote. Dr. Nieva, an oncologist at the University of Southern California, Los Angeles, disagreed with the FDA’s question about limiting use of the olaparib-abiraterone combination to patients with known BRCA mutations, citing the positive result from the PROpel trial.

People are aware that olaparib provides a great deal more benefit in the BRCA-positive group and may give “only minimal benefit if these tests are not positive,” but “these risks and benefits can be addressed at the patient and physician level,” he said.

But Terrence M. Kungel, MBA, who served as ODAC’s patient representative for the meeting, offered a counterpoint to Dr. Nieva’s assessment. Patients now often struggle to assess the options available to them and then pay for these medicines, with financial toxicity affecting many people with cancer.

“Prostate cancer patients need more treatments that are effective, not more choices,” said Mr. Kungel, who voted with the majority.

That meant the ODAC members were being asked to evaluate a drug based on “suboptimal data” resulting from a “suboptimal study design,” said Dr. Madan, who is head of the prostate cancer clinical research section in the NCI’s Center for Cancer Research.

Dr. Madan also emphasized concerns the FDA raised about the potential harms for patients whose prostate cancer was not tied to BRCA mutations. In the FDA’s briefing document, the agency said patients treated in the first-line metastatic castration-resistant prostate cancer setting generally have few symptoms at baseline. Adding olaparib among patients lacking the BRCA mutation could expose them to a drug with known side effects but minimal chance to help them.

The PROpel trial also found that patients who received olaparib and abiraterone experienced greater toxicity than those who received abiraterone. These adverse events included venous thromboembolic events, myelosuppression, requirement for blood transfusions, nausea, vomiting, and diarrhea.

Although the FDA is not compelled to follow the recommendations of its advisory committees, it often does.

AstraZeneca expressed some disappointment about the recommendation in a press release. Susan Galbraith, executive vice president of Oncology R&D at AstraZeneca, said, “while we are pleased with the recognition of the benefit of Lynparza plus abiraterone for patients with BRCA-mutated metastatic castration-resistant prostate cancer, we are disappointed with the outcome of today’s ODAC meeting. We strongly believe in the results of the PROpel trial, which demonstrated the clinically meaningful benefit for this combination in a broad population of patients regardless of biomarker status.”

One ODAC member, Jorge J. Nieva, MD, did support the expanded approval for olaparib, casting the single “no” vote. Dr. Nieva, an oncologist at the University of Southern California, Los Angeles, disagreed with the FDA’s question about limiting use of the olaparib-abiraterone combination to patients with known BRCA mutations, citing the positive result from the PROpel trial.

People are aware that olaparib provides a great deal more benefit in the BRCA-positive group and may give “only minimal benefit if these tests are not positive,” but “these risks and benefits can be addressed at the patient and physician level,” he said.

But Terrence M. Kungel, MBA, who served as ODAC’s patient representative for the meeting, offered a counterpoint to Dr. Nieva’s assessment. Patients now often struggle to assess the options available to them and then pay for these medicines, with financial toxicity affecting many people with cancer.

“Prostate cancer patients need more treatments that are effective, not more choices,” said Mr. Kungel, who voted with the majority.

A panel of independent advisers recently almost unanimously recommended to restrict a new indication for olaparib (Lynparza) alongside abiraterone (Zytiga) in patients with metastatic castration-resistant prostate cancer.

On April 28, members of the Oncologic Drugs Advisory Committee voted 11 to 1, with one abstention, that only patients whose tumors have a BRCA mutation should receive olaparib as part of the combination first-line treatment for metastatic castration-resistant prostate cancer.

Olaparib is already cleared by the Food and Drug Administration for various ovarian, breast, and pancreatic cancer indications as well as later-line use in certain more advanced prostate cancers. AstraZeneca recently applied for an additional, broad indication for the poly (ADP-ribose) polymerase (PARP) inhibitor as an initial therapy that would include patients without BRCA or homologous recombination repair (HRR) mutations.

In reviewing the application, the FDA raised concerns about this broad new indication, highlighting limitations in the key research used to justify the expanded use and highlighting how olaparib may amount to a “toxic placebo,” a phrase agency staff used in their briefing document.

Given these concerns, the FDA reviewers asked the independent ODAC panel to vote on the following question: “As FDA reviews the proposed indication for olaparib in combination with abiraterone for initial treatment of [metastatic castration-resistant prostate cancer], should the indication be restricted to patients whose tumors have a BRCA mutation?”

The ODAC panel voted 11 to 1 in favor of a restricted expansion of olaparib plus abiraterone and prednisone or prednisolone to patients whose tumors have a BRCA mutation. One member – Ravi A. Madan, MD, of the National Cancer Institute – abstained. The FDA staff asked panelists to abstain if they felt the combination treatment should not be approved for any indication.

Overall, the ODAC panel agreed with the FDA staff’s criticism of the research supporting the application: the PROpel study. The trial randomized 796 patients with previously untreated metastatic castration-resistant prostate cancer to olaparib plus abiraterone or abiraterone plus placebo. The median time for radiographic progression-free survival – the study’s primary endpoint – was nearly 25 months in the olaparib group versus 16.6 months in the placebo group.

The combination also demonstrated a 19% reduced risk of death, which was not statistically significant (hazard ratio, 0.81; P = .0544), and a median improvement of 7.4 months in the combination arm (42.1 vs. 34.7 months).

Although the study met its primary endpoint, the results were difficult to interpret given the lack of information about genetic variability in the participants’ tumors. Participants were not prospectively assessed for either BRCA or HRR status. But given the importance of BRCA status as a predictive biomarker for PARP inhibitor efficacy, “this trial design would be considered inappropriate today as the biomarker should have been prospectively evaluated,” the FDA wrote in its briefing document.

A genetic sequencing effort identified more patients to be carriers of risk genes for hereditary breast and ovarian cancer or Lynch syndrome than would have been discovered by following existing genetic testing guidelines, according to new research.

The authors of the clinical trial suggest that these guidelines may need to be revised.

Individuals with hereditary breast and ovarian cancer (HBOC) have an 80% lifetime risk of breast cancer and are at greater risk of ovarian cancer, pancreatic cancer, prostate cancer, and melanoma. Those with Lynch syndrome (LS) have an 80% lifetime risk of colorectal cancer, a 60% lifetime risk of endometrial cancer, and heightened risk of upper gastrointestinal, urinary tract, skin, and other tumors, said study coauthor N. Jewel Samadder, MD in a statement.

The National Cancer Control Network has guidelines for determining family risk for colorectal cancer and breast, ovarian, and pancreatic cancer to identify individuals who should be screened for LS and HBOC, but these rely on personal and family health histories.

“These criteria were created at a time when genetic testing was cost prohibitive and thus aimed to identify those at the greatest chance of being a mutation carrier in the absence of population-wide whole-exome sequencing. However, [LS and HBOC] are poorly identified in current practice, and many patients are not aware of their cancer risk,” said Dr. Samadder, professor of medicine and coleader of the precision oncology program at the Mayo Clinic Comprehensive Cancer Center, Phoenix, in the statement.

Whole-exome sequencing covers only protein-coding regions of the genome, which is less than 2% of the total genome but includes more than 85% of known disease-related genetic variants, according to Emily Gay, who presented the trial results (Abstract 5768) on April 18 at the annual meeting of the American Association for Cancer Research.

“In recent years, the cost of whole-exome sequencing has been rapidly decreasing, allowing us to complete this test on saliva samples from thousands, if not tens of thousands of patients covering large populations and large health systems,” said Ms. Gay, a genetic counseling graduate student at the University of Arizona, during her presentation.

She described results from the TAPESTRY clinical trial, with 44,306 participants from Mayo Clinic centers in Arizona, Florida, and Minnesota, who were identified as definitely or likely to be harboring pathogenic mutations and consented to whole-exome sequencing from saliva samples. They used electronic health records to determine whether patients would satisfy the testing criteria from NCCN guidelines.

The researchers identified 1.24% of participants to be carriers of HBOC or LS. Of the HBOC carriers, 62.8% were female, and of the LS carriers, 62.6% were female. The percentages of HBOC and LS carriers who were White were 88.6 and 94.5, respectively. The median age of both groups was 57 years. Of HBOC carriers, 47.3% had personal histories of cancers; for LS carries, the percentage was 44.2.

Of HBOC carriers, 49.1% had been previously unaware of their genetic condition, while an even higher percentage of patients with LS – 59.3% – fell into that category. Thirty-two percent of those with HBOC and 56.2% of those with LS would not have qualified for screening using the relevant NCCN guidelines.

“Most strikingly,” 63.8% of individuals with mutations in the MSH6 gene and 83.7% of those mutations in the PMS2 gene would not have met NCCN criteria, Ms. Gay said.

Having a cancer type not known to be related to a genetic syndrome was a reason for 58.6% of individuals failing to meet NCCN guidelines, while 60.5% did not meet the guidelines because of an insufficient number of relatives known to have a history of cancer, and 63.3% did not because they had no personal history of cancer. Among individuals with a pathogenic mutation who met NCCN criteria, 34% were not aware of their condition.

“This suggests that the NCCN guidelines are underutilized in clinical practice, potentially due to the busy schedule of clinicians or because the complexity of using these criteria,” said Ms. Gay.

The numbers were even more striking among minorities: “There is additional data analysis and research needed in this area, but based on our preliminary findings, we saw that nearly 50% of the individuals who are [part of an underrepresented minority group] did not meet criteria, compared with 32% of the white cohort,” said Ms. Gay.

Asked what new NCCN guidelines should be, Ms. Gay replied: “I think maybe limiting the number of relatives that you have to have with a certain type of cancer, especially as we see families get smaller and smaller, especially in the United States – that family data isn’t necessarily available or as useful. And then also, I think, incorporating in the size of a family into the calculation, so more of maybe a point-based system like we see with other genetic conditions rather than a ‘yes you meet or no, you don’t.’ More of a range to say ‘you fall on the low-risk, medium-risk, or high-risk stage,’” said Ms. Gay.

During the Q&A period, session cochair Andrew Godwin, PhD, who is a professor of molecular oncology and pathology at University of Kansas Medical Center, Kansas City, said he wondered if whole-exome sequencing was capable of picking up cancer risk mutations that standard targeted tests don’t look for.

Dr. Samadder, who was in the audience, answered the question, saying that targeted tests are actually better at picking up some types of mutations like intronic mutations, single-nucleotide polymorphisms, and deletions.

“There are some limitations to whole-exome sequencing. Our estimate here of 1.2% [of participants carrying HBOC or LS mutations] is probably an underestimate. There are additional variants that exome sequencing probably doesn’t pick up easily or as well. That’s why we qualify that exome sequencing is a screening test, not a diagnostic,” he continued.

Ms. Gay and Dr. Samadder have no relevant financial disclosures. Dr. Godwin has financial relationships with Clara Biotech, VITRAC Therapeutics, and Sinochips Diagnostics.

Over the past 30 years, more than 80 new systemic therapies for cancer have been approved, and many patients diagnosed with localized disease have benefited with improved progression-free and overall survival. The same can be said for some – but by no means all – patients with metastatic disease at diagnosis, a new study indicates.

“Our results show that the survival of patients with de novo metastatic cancer improved slowly over 30 years but that these gains were typically modest and unevenly distributed among cancers,” comment the authors, led by Marianne Luyendijk, MSc, from the Netherlands Comprehensive Cancer Organization, Utrecht.

The study was published online  in the Journal of the National Cancer Institute.

The retrospective study compared survival data of patients with de novo metastatic disease diagnosed from 1989 through 1993 with those of patients diagnosed from 2014 to 2018.

The results show that 5-year survival increased by 15% or more among patients with metastatic gastrointestinal stromal tumors; neuroendocrine tumors; melanoma; and cancers of the prostate, breast, thyroid, and testes.

For patients with other cancers, however, the gains in survival were more modest. For example, over the study period, 5-year survival of patients with metastatic non–small cell lung cancer increased by only 6%, a disappointing finding, given the advent of targeted therapies and immunotherapy during the most recent period, the authors note.

In contrast, there was a 16% improvement in long-term survival of patients with metastatic melanoma, likely owing to the introduction of immune checkpoint inhibitors and targeted therapies, such as tyrosine kinase inhibitors.

The data also showed differences over time in the proportion of patients diagnosed with de novo metastatic disease; some cancers, such as NSCLC and small cell lung cancer, were more frequently diagnosed at late stages in the more recent era, possibly owing to increased screening and the use of technology such as FDG-PET imaging.

On the other end of the spectrum, cancers of the prostate, rectum, uterine cervix, breast, gallbladder, and bile ducts were more likely to be caught at an earlier stage during later years of the study period.

The authors say that among the possible explanations for a less than robust reduction over time in metastatic disease is that new drugs do not always translate into improved survival. They cite a 2017 study showing that among 53 new cancer drugs approved by U.S., European, or Australian drug regulators, fewer than half improved overall survival by at least 3 months, and an additional 26% offered survival advantages that were either shorter than 3 months or of unknown benefit.

“This may also explain why the 1- and 5-year survival rates of some cancers have changed little in the last 30 years,” they write. “Nevertheless, even minor benefits in survival or other outcomes (for example, quality of life) may represent progress in treating patients with metastatic cancer.”

The investigators recommend that to improve understanding of the effect of new therapies on survival of metastatic disease, cancer registries include data on therapies used beyond the first line, as well as comorbidities and quality-of-life measures.

The authors did not report a study funding source. Ms. Luyendijk has disclosed no relevant financial relationships. Several co-authors reported financial relationships with pharmaceutical companies.

They cite a 2017 study showing that among 53 new cancer drugs approved by U.S., European, or Australian drug regulators, fewer than half improved overall survival by at least 3 months, and an additional 26% offered survival advantages that were either shorter than 3 months or of unknown benefit.

“This may also explain why the 1- and 5-year survival rates of some cancers have changed little in the last 30 years,” they write. “Nevertheless, even minor benefits in survival or other outcomes (for example, quality of life) may represent progress in treating patients with metastatic cancer.”

The investigators recommend that to improve understanding of the effect of new therapies on survival of metastatic disease, cancer registries include data on therapies used beyond the first line, as well as comorbidities and quality-of-life measures.

A radioligand treatment approved for certain men with metastatic castration-resistant prostate cancer is in short supply because of manufacturing and delivery issues, according to the Food and Drug Administration. 

The therapy lutetium Lu 177 vipivotide tetraxetan (Pluvicto), approved in March 2022, will remain in limited supply until the drug’s manufacturer, Novartis, can ramp up production of the drug over the next 12 months.

In a letter in February, Novartis said it is giving priority to patients who have already started the regimen so they can “appropriately complete their course of therapy.” The manufacturer will not be taking any orders for new patients over the next 4-6 months, as they work to increase supply.

“We are operating our production site at full capacity to treat as many patients as possible, as quickly as possible,” Novartis said. “However, with a nuclear medicine like Pluvicto, there is no backup supply that we can draw from when we experience a delay.”

Pluvicto is currently made in small batches in the company’s manufacturing facility in Italy. The drug only has a 5-day window to reach its intended patient, after which time it cannot be used. Any disruption in the production or shipping process can create a delay.

Novartis said the facility in Italy is currently operating at full capacity and the company is “working to increase production capacity and supply” of the drug over the next 12 months at two new manufacturing sites in the United States. 

The company also encountered supply problems with Pluvicto in 2022 after quality issues were discovered in the manufacturing process.

Currently, patients who are waiting for their first dose of Pluvicto will need to be rescheduled. The manufacturer will be reaching out to health care professionals with options for rescheduling.

Jonathan McConathy, MD, PhD, told The Wall Street Journal that “people will die from this shortage, for sure.”

Dr. McConathy, a radiologist at the University of Alabama at Birmingham who has consulted for Novartis, explained that some patients who would have benefited from the drug likely won’t receive it in time.
