Intensive surveillance after CRC resection does not improve survival

Article Type

Wed, 05/26/2021 - 13:42

Intensive surveillance with carcinoembryonic antigen (CEA) testing and CT scans after colorectal cancer resection did not improve recurrence-free or overall survival when compared with standard abdominal ultrasound and chest x-ray monitoring in a phase 3 trial of almost 2,000 patients.

However, among patients with colon cancer recurrence, those randomized to intensive surveillance more often had a second surgery with curative intent. Even so, there was no overall survival benefit versus standard surveillance in this group.

In short, “none of the follow-up modalities resulted in a difference,” said investigator Come Lepage, MD, PhD, of Centre Hospitalier Universitaire de Dijon (France).

Dr. Lepage presented these findings at the European Society for Medical Oncology Virtual Congress 2020.

Dr. Lepage said the study’s results suggest guidelines that include CT and CEA monitoring should be amended, and the standard surveillance methods should be ultrasound and chest x-ray. Dr. LePage called CEA surveillance “useless” and said CT scans should be performed only in cases of suspected recurrence.

However, study discussant Tim Price, MBBS, DHSc, of the University of Adelaide, noted that both the intensive and standard arms in this study had abdominal imaging every 3 months, be it ultrasound or CT, so even in the standard arms, surveillance “was still fairly aggressive.”

Because of that, the study does not “suggest we should decrease our intensity,” Dr. Price said.

He added that the study’s major finding was that more intensive surveillance led to higher rates of secondary surgery with curative intent, probably because recurrences were caught earlier than they would have been with standard surveillance, when curative surgery was still possible.

Patients in the study were treated during 2009-2015, and that might have also made a difference. “We need to remember that, in 2020, care is very different,” Dr. Price said. This includes increased surgical interventions and options for oligometastatic disease, plus systemic therapies such as pembrolizumab. With modern treatments, detecting recurrences earlier “may well have an impact on survival.”

Perhaps patients would live longer with “earlier diagnosis in today’s setting with more active agents and more aggressive surgery and radiotherapy [e.g., stereotactic ablative radiation therapy],” Dr. Price said in an interview.
 

Study details

The trial, dubbed PRODIGE 13, was done to bring clarity to the surveillance issue. Intensive follow-up after curative surgery for colorectal cancer, including CT and CEA monitoring, is recommended by various scientific societies, but it’s based mainly on expert opinion. Results of the few clinical trials on the issue have been controversial, Dr. Lepage explained.

PRODIGE 13 included 1,995 subjects with colorectal cancer. About half of patients had stage II disease, and the other half had stage III. Most patients were 75 years or younger at baseline, and there were more men in the study than women. All patients underwent resection with curative intent and had no evidence of residual disease 3 months after surgery. Some patients received adjuvant chemotherapy.

Patients were first randomized to no CEA monitoring or CEA monitoring every 3 months for the first 2 years, then every 6 months for an additional 3 years. Members in both groups were then randomized a second time to either intensive or standard radiologic surveillance.

Surveillance in the standard arm consisted of an abdominal ultrasound every 3 months for the first 3 years, then biannually for an additional 2 years, plus chest x-rays every 6 months for 5 years. Intensive surveillance consisted of CT imaging, including thoracic imaging, alternating with abdominal ultrasound, every 3 months, then biannually for another 2 years.

At baseline, the surveillance groups were well balanced with regard to demographics, primary tumor location, and other factors, but stage III disease was more prevalent among patients randomized to standard radiologic monitoring without CEA.
 

 

 

Results

The median follow up was 6.5 years. There were no significant differences between the surveillance groups with regard to 5-year overall survival (P = .340) or recurrence-free survival (P = .473).

There were no significant differences in recurrence-free or overall survival when patients were stratified by age, sex, stage, CEA at a cut point of 5 mcg/L, and primary tumor characteristics including location, perineural invasion, and occlusion/perforation.

There were 356 recurrences in patients initially treated for colon cancer. CEA surveillance with or without CT scan was associated with an increased incidence of secondary resection with curative intent. The rate of secondary resection was 66.3% in the standard imaging with CEA arm, 59.5% in the CT plus CEA arm, 50.7% with CT imaging but no CEA, and 40.9% with standard imaging and no CEA (P = .0035).

The rates were similar among the 83 patients with recurrence after initial treatment for rectal cancer, but the between-arm differences were not significant. The rate of secondary resection with curative intent was 57.9% in the standard imaging with CEA arm, 47.8% in the CT plus CEA arm, 55% with CT imaging but no CEA, and 42.9% with standard imaging and no CEA.

The research is ongoing, and the team expects to report on secondary outcomes and ancillary studies of circulating tumor DNA, among other things, in 2021.

The study is being funded by the Federation Francophone de Cancerologie Digestive. Dr. Lepage disclosed ties with Novartis, Amgen, Bayer, Servier, and AAA. Dr. Price disclosed institutional research funding from Amgen and being an uncompensated adviser to Pierre-Fabre and Merck.

Study advances personalized treatment for older breast cancer patients

Article Type

Most older women with estrogen receptor–positive (ER+) breast cancer can tolerate and should be offered surgery, and a new tool helps them decide between treatment options, the U.K. Age Gap study suggests. Findings from the study were reported at the 12th European Breast Cancer Conference.

Dr. Lynda Wyld

“Primary endocrine therapy is usually reserved for older, less fit, and frail women. Rates of use vary widely,” noted investigator Lynda Wyld, MBChB, PhD, of the University of Sheffield (England).

“Although there is no set threshold for who is suitable, some women are undoubtedly over- and undertreated for their breast cancer,” she added.

Dr. Wyld and colleagues undertook the Age Gap study among women older than 70 years with breast cancer recruited from 56 U.K. breast units during 2013-2018.

The main goals were to determine which women can be safely offered primary endocrine therapy as nonstandard care and to develop and test a tool to help women in this age group make treatment decisions.

The first component of the study was a multicenter, prospective cohort study of women with ER+ disease who were eligible for surgery. Results showed that breast cancer–specific mortality was greater with primary endocrine therapy than with surgery in the entire cohort. However, breast cancer–specific mortality was lower with primary endocrine therapy than with surgery in a cohort matched with propensity scores to achieve similar age, fitness, and frailty.

The second component of the study was a cluster-randomized controlled trial of women with operable breast cancer, most of whom had ER+ disease. Results showed that a decision support tool increased awareness of treatment options and readiness to decide. The tool also altered treatment choices, prompting a larger share of patients with ER+ disease to choose primary endocrine therapy.
 

Prospective cohort study

The prospective observational study was conducted in 2,854 women with ER+ disease who were eligible for surgery and treated in usual practice. Most women (n = 2,354) were treated with surgery (followed by antiestrogen therapy), while the rest received primary endocrine therapy (n = 500).

In the entire cohort, patients undergoing surgery were younger, had a lower level of comorbidity, and were less often frail. But these characteristics were generally similar in a propensity-matched cohort of 672 patients.

At a median follow-up of 52 months, overall and breast cancer–specific survival were significantly poorer with primary endocrine therapy versus surgery in the entire cohort but not in the propensity-matched cohort.

In the entire cohort, the breast cancer–specific mortality was 9.5% with primary endocrine therapy and 4.9% with surgery. In the propensity-matched cohort, breast cancer–specific mortality was 3.1% and 6.6%, respectively.

The overall mortality was 41.8% with primary endocrine therapy and 14.6% with surgery in the entire cohort, but the gap narrowed to 34.5% and 25.6%, respectively, in the propensity-matched cohort.

In the latter, “although there is a slight divergence in overall survival and it’s likely that with longer-term follow-up this will become significant, at the moment, it isn’t,” Dr. Wyld commented.

Curves for breast cancer–specific survival basically overlapped until 5 years, when surgery started to show an advantage. The rate of locoregional recurrence or progression was low and not significantly different by treatment.

None of the women in the entire cohort died from surgery. “But it’s worth bearing in mind that these were all women selected for surgery, who were thought to be fit for it by their surgeons. The least fit women in this cohort will have obviously been offered primary endocrine therapy,” Dr. Wyld cautioned.

Although 19% of patients had a surgical complication, only 2.1% had a systemic surgical complication.
 

 

 

Cluster-randomized controlled trial

In the cluster-randomized controlled trial, researchers compared a decision support tool to usual care. The tool was developed using U.K. registry data from almost 30,000 older women and input from women in this age group on their preferred format and method of presentation, according to Dr. Wyld.

The tool consists of an algorithm available to clinicians online (for input of tumor stage and biology, comorbidities, and functional status) plus a booklet and outcome sheets for patients to take home after discussions that can be personalized to their particulars.

Intention-to-treat analyses were based on 1,339 patients with operable breast cancer, 1,161 of whom had ER+ disease. Per-protocol analyses were based on the subset of 449 patients who were offered a choice between surgery and primary endocrine therapy, presumably because they were less fit and frailer.

Results showed that, at 6 months, mean scores for global quality of life on the EORTC questionnaire did not differ between decision support and usual care in the intention-to-treat population (69.0 vs. 68.9; P = .900), but scores were more favorable with decision support in the per-protocol population (70.7 vs. 66.8; P = .044).

The tool also altered treatment choices, with a larger share of ER+ patients choosing primary endocrine therapy (21.0% vs. 15.4%; P = .029) but still having similar disease outcomes.

Although ER+ patients in the decision support group more often selected primary endocrine therapy, at a median follow-up of 36 months, the groups did not differ significantly on overall survival, cause-specific survival, or time to recurrence in either intention-to-treat or per-protocol analyses.

Larger shares of women in the decision support group reported that they had adequate knowledge about the treatment options available to them (94% vs. 74%), were aware of the advantages and disadvantages of each option (91% vs. 76%), knew which option they preferred (96% vs. 91%), and were ready to make a decision (99% vs. 90%).
 

Applying results to practice

“Most women over the age of 70 are relatively fit, and the aim should be to treat them with surgery,” Dr. Wyld said. “For the less fit, a point is reached where the oncology benefits of surgery disappear and surgery may just cause harm. This threshold appears to be for women in their mid-80s with moderate to poor health.”

“Use of the Age Gap online tool may enhance shared decision-making for these women while increasing knowledge. And whilst it does seem to increase the use of primary endocrine therapy, this does not seem to have an adverse impact on survival at 36 months of follow-up,” she added.

Dr. Lesly A. Dossett

“The study by Dr. Wyld and colleagues adds to the available literature regarding the scenarios in which some treatments may be omitted without impacting overall survival in older women with breast cancer,” Lesly A. Dossett, MD, of Michigan Medicine in Ann Arbor, commented in an interview.

In her own practice, Dr. Dossett emphasizes the generally favorable prognosis for older women with hormone receptor–positive breast cancer, she said. However, tools that help communicate risk and clarify the value of various therapies are welcome.

“The decision support tool appears to be a promising tool in helping to avoid treatments that are unlikely to benefit older women with breast cancer,” Dr. Dossett said. “The results will be widely applicable, as there is growing recognition that this patient population is at risk for overtreatment.”

The study was funded by the U.K. National Institute for Health Research programme grant for applied research. Dr. Wyld and Dr. Dossett said they had no relevant conflicts of interest.

Dr. Wyld and colleagues undertook the Age Gap study among women older than 70 years with breast cancer recruited from 56 U.K. breast units during 2013-2018.

The main goals were to determine which women can be safely offered primary endocrine therapy as nonstandard care and to develop and test a tool to help women in this age group make treatment decisions.

The first component of the study was a multicenter, prospective cohort study of women with ER+ disease who were eligible for surgery. Results showed that breast cancer–specific mortality was greater with primary endocrine therapy than with surgery in the entire cohort. However, breast cancer–specific mortality was lower with primary endocrine therapy than with surgery in a cohort matched with propensity scores to achieve similar age, fitness, and frailty.

The second component of the study was a cluster-randomized controlled trial of women with operable breast cancer, most of whom had ER+ disease. Results showed that a decision support tool increased awareness of treatment options and readiness to decide. The tool also altered treatment choices, prompting a larger share of patients with ER+ disease to choose primary endocrine therapy.
 

Prospective cohort study

The prospective observational study was conducted in 2,854 women with ER+ disease who were eligible for surgery and treated in usual practice. Most women (n = 2,354) were treated with surgery (followed by antiestrogen therapy), while the rest received primary endocrine therapy (n = 500).

In the entire cohort, patients undergoing surgery were younger, had a lower level of comorbidity, and were less often frail. But these characteristics were generally similar in a propensity-matched cohort of 672 patients.

At a median follow-up of 52 months, overall and breast cancer–specific survival were significantly poorer with primary endocrine therapy versus surgery in the entire cohort but not in the propensity-matched cohort.

In the entire cohort, the breast cancer–specific mortality was 9.5% with primary endocrine therapy and 4.9% with surgery. In the propensity-matched cohort, breast cancer–specific mortality was 3.1% and 6.6%, respectively.

The overall mortality was 41.8% with primary endocrine therapy and 14.6% with surgery in the entire cohort, but the gap narrowed to 34.5% and 25.6%, respectively, in the propensity-matched cohort.

In the latter, “although there is a slight divergence in overall survival and it’s likely that with longer-term follow-up this will become significant, at the moment, it isn’t,” Dr. Wyld commented.

Curves for breast cancer–specific survival basically overlapped until 5 years, when surgery started to show an advantage. The rate of locoregional recurrence or progression was low and not significantly different by treatment.

None of the women in the entire cohort died from surgery. “But it’s worth bearing in mind that these were all women selected for surgery, who were thought to be fit for it by their surgeons. The least fit women in this cohort will have obviously been offered primary endocrine therapy,” Dr. Wyld cautioned.

Although 19% of patients had a surgical complication, only 2.1% had a systemic surgical complication.
 

 

 

Cluster-randomized controlled trial

In the cluster-randomized controlled trial, researchers compared a decision support tool to usual care. The tool was developed using U.K. registry data from almost 30,000 older women and input from women in this age group on their preferred format and method of presentation, according to Dr. Wyld.

The tool consists of an algorithm available to clinicians online (for input of tumor stage and biology, comorbidities, and functional status) plus a booklet and outcome sheets for patients to take home after discussions that can be personalized to their particulars.

Intention-to-treat analyses were based on 1,339 patients with operable breast cancer, 1,161 of whom had ER+ disease. Per-protocol analyses were based on the subset of 449 patients who were offered a choice between surgery and primary endocrine therapy, presumably because they were less fit and frailer.

Results showed that, at 6 months, mean scores for global quality of life on the EORTC questionnaire did not differ between decision support and usual care in the intention-to-treat population (69.0 vs. 68.9; P = .900), but scores were more favorable with decision support in the per-protocol population (70.7 vs. 66.8; P = .044).

The tool also altered treatment choices, with a larger share of ER+ patients choosing primary endocrine therapy (21.0% vs. 15.4%; P = .029) but still having similar disease outcomes.

Although ER+ patients in the decision support group more often selected primary endocrine therapy, at a median follow-up of 36 months, the groups did not differ significantly on overall survival, cause-specific survival, or time to recurrence in either intention-to-treat or per-protocol analyses.

Larger shares of women in the decision support group reported that they had adequate knowledge about the treatment options available to them (94% vs. 74%), were aware of the advantages and disadvantages of each option (91% vs. 76%), knew which option they preferred (96% vs. 91%), and were ready to make a decision (99% vs. 90%).
 

Applying results to practice

“Most women over the age of 70 are relatively fit, and the aim should be to treat them with surgery,” Dr. Wyld said. “For the less fit, a point is reached where the oncology benefits of surgery disappear and surgery may just cause harm. This threshold appears to be for women in their mid-80s with moderate to poor health.”

“Use of the Age Gap online tool may enhance shared decision-making for these women while increasing knowledge. And whilst it does seem to increase the use of primary endocrine therapy, this does not seem to have an adverse impact on survival at 36 months of follow-up,” she added.

Dr. Lesly A. Dossett

“The study by Dr. Wyld and colleagues adds to the available literature regarding the scenarios in which some treatments may be omitted without impacting overall survival in older women with breast cancer,” Lesly A. Dossett, MD, of Michigan Medicine in Ann Arbor, commented in an interview.

In her own practice, Dr. Dossett emphasizes the generally favorable prognosis for older women with hormone receptor–positive breast cancer, she said. However, tools that help communicate risk and clarify the value of various therapies are welcome.

“The decision support tool appears to be a promising tool in helping to avoid treatments that are unlikely to benefit older women with breast cancer,” Dr. Dossett said. “The results will be widely applicable, as there is growing recognition that this patient population is at risk for overtreatment.”

The study was funded by the U.K. National Institute for Health Research programme grant for applied research. Dr. Wyld and Dr. Dossett said they had no relevant conflicts of interest.

High-dose TRT: A new standard of care for LS-SCLC?

Article Type
Changed
Mon, 11/23/2020 - 12:39

 

A higher dose of thoracic radiotherapy (TRT) may improve overall survival in limited-stage small-cell lung cancer (LS-SCLC), but it’s not clear if this dose should become the new standard of care.

In a phase 2 trial, the 2-year overall survival rate was 51.3% when twice-daily TRT was given at a dose of 45 Gy in 30 fractions and 75% when it was given at a dose of 60 Gy in 40 fractions in patients with LS-SCLC. The two treatment arms had similar safety and quality of life outcomes.

The higher dose “did not add toxicity,” a significant concern with higher radiation doses, said Bjorn Gronberg, MD, PhD, of the Norwegian University of Science and Technology in Trondheim, when presenting this study at the European Society for Medical Oncology Virtual Congress 2020.

However, the discussant for this study pointed out several limitations of the trial and concluded that the 45 Gy dose should remain the standard of care.

Dr. Gonberg explained that concurrent platinum/etoposide (PE) chemotherapy and TRT is the standard treatment for LS-SCLC, and the most recommended schedule for TRT is twice daily at 45 Gy in 30 fractions. He noted, however, that “there’s clearly a need for better treatment” because less than 30% of patients are cured.

“We hypothesized that increasing the dose of radiotherapy might improve survival,” he said.
 

Study details

Dr. Gonberg and colleagues conducted a phase 2 trial of patients with stage I-III SCLC confined to one hemithorax plus regional lymph nodes. The trial enrolled 176 patients and randomized 170 of them.

The patients received four courses of PE 3 weeks apart. For TRT, 81 patients were randomized to 45 Gy in 30 fractions, and 89 patients were randomized to 60 Gy in 40 fractions, with 10 fractions per week starting with the second PE course.

All patients who responded to chemoradiotherapy were offered prophylactic cranial irradiation at 25 Gy in 10 fractions or 30 Gy in 15 fractions.

Baseline characteristics were well balanced between the treatment arms. The median age was 65 years in both arms, and most patients were women (60.5% in the 45 Gy arm and 56% in the 60 Gy arm).

The mean number of chemotherapy courses was 3.8 in each arm, about 85% of patients received prophylactic cranial radiation, and roughly half received second-line chemotherapy. Overall, 73 patients completed TRT in the 45 Gy arm, and 81 completed TRT in the 60 Gy arm.
 

Efficacy

There was no significant difference in overall response rate between the treatment arms. It was 81.6% in the 45 Gy arm and 82.1% in the 60 Gy arm (P = .81).

Similarly, there was no significant difference in progression-free survival. The median progression-free survival was 11.1 months in the lower-dose arm and 18.7 months in the higher-dose arm (P = .22).

Still, there was a significant difference in overall survival between the arms. The 2-year overall survival rate was 51.3% in the lower-dose arm and 75% in the higher-dose arm (P = .002). The median overall survival was 24 months and 37.2 months, respectively (P = .034).

Discussant Corinne Faivre-Finn, MD, PhD, of the University of Manchester (England), cautioned that the lower-dose arm appeared to underperform, compared with prior research.

Additionally, “the survival curves separate at about 9 months, [with a] significant difference at 2 years, but the survival curves are coming back together at around 5 years, and that shows that there is a small difference in terms of long-term cure,” she said.
 

 

 

Safety

There were no significant differences in toxicity between the treatment arms.

Dr. Gronberg noted that esophagitis is considered the main dose-limiting toxicity with TRT, but there was no difference in incidence between the two arms (P = .916). Grade 3 esophagitis occurred in 18.4% of patients in the lower-dose arm and 19% of those in the higher-dose arm. There was no grade 4 esophagitis.

Rates of grade 3 and 4 neutropenic infections were higher in the lower-dose arm than in the higher-dose arm, but the difference was not statistically significant (P = .08).

There were also no significant differences in quality of life surveys that patients filled out periodically from baseline until week 52.

“Not so surprisingly,” Dr. Gronberg said, dysphagia was more common at the end of TRT. However, patients had recovered to baseline levels at week 22.

“There’s no difference in the maximum dysphagia reported between the treatment arms, but ... patients in the high-dose arm needed longer time to recover from dysphagia,” Dr. Gronberg said.

Scores for dyspnea, physical function, and global quality of life were similar between the treatment arms.

The similar toxicity between the arms “is quite puzzling,” Dr. Faivre-Finn said, given the 33% increase in radiation dose in the experimental arm. She said this “probably points out an imbalance in some of the factors” between the groups, including tumor volume and doses to organs at risk, which were not reported.

“There are some important missing data, in terms of interpretation of results,” she said.

Given the limitations, and the fact that the study population was relatively small, Dr. Faivre-Finn said “the results cannot be considered definitive and practice changing,” pending additional study.

“So my final conclusion is that twice-a-day radiotherapy at a dose of 45 Gy remains the standard of care, as recommended in the recently published ASTRO [American Society for Radiation Oncology] guidelines,” Dr. Faivre-Finn said.

The study was funded by the Norwegian Cancer Society, the Nordic Cancer Union, and the Norwegian University of Science and Technology. Dr. Gronberg disclosed relationships with Pfizer, Roche, Eli Lilly, and other companies. Dr. Faivre-Finn disclosed relationships with AstraZeneca, Merck, Pfizer, Elekta, and Boehringer Ingelheim.

CRC risk: Raised by meat/alcohol, lowered by aspirin/NSAIDs

Article Type
Changed
Wed, 05/26/2021 - 13:42

A new meta-analysis has largely confirmed what is already known about the lifestyle factors that increase and those that decrease the risk of developing colorectal cancer.

The use of aspirin and nonsteroidal anti-inflammatory drugs (NSAIDs) is associated with a decreased risk for colorectal cancer, the new article concludes. But it also adds a number of other factors that are associated with a decreased risk for the disease, including taking magnesium and folate supplements and eating dairy products, fiber, soy, and fruits and vegetables.

On the other hand, consumption of meat and alcohol was associated with an increased risk for colorectal cancer in almost all of the analyses included in this article.

The study was published online September 28 in Gut.

However, the authors pointed out that it is important to keep in mind that in most cases, the level of evidence is low or very low, primarily because of the heterogeneity of the various published studies, as well as the type of study.

“Furthermore, in most cases, we were unable to identify an optimal dose and duration of exposure/intake for any of the products, even in the case of low-dose aspirin and other compounds that have been extensively assessed,” they wrote.

The findings of this new meta-analysis echo previous findings on this issue.

A number of studies, for example, have found varying associations between the consumption of red meat and cancer. The American Institute for Cancer Research and the World Cancer Research Fund have published several reports during the past 10 years on the effect of diet, nutrition, and/or physical activity on risk for several cancer types. Their most recent study, published in 2017, concluded that eating red meat and processed meat may increase the risk for colorectal cancer, as may drinking two or more alcoholic beverages per day.

Another large meta-analysis published earlier this year found that regular use of aspirin reduced the risk for cancers of the digestive tract by 22%-38%, compared with nonuse.
 

Umbrella review

In the latest article in Gut, researchers led by Marc Bardou, MD, PhD, Centre Hospitalier Universitaire de Dijon (France), conducted an umbrella review of systematic reviews and meta-analyses of interventions that assessed chemopreventive products for colorectal cancer in an average-risk population.

A total of 80 meta-analyses of interventional and observational studies were included. The studies investigated a wide range of chemopreventive agents in an average-risk population and the risk for colorectal cancer. Agents included medications (aspirin, NSAIDs, statins), vitamins or supplements (magnesium; calcium; folic acid; vitamin A, B, C, E, and D; beta-carotene; and selenium), and dietary items (coffee, tea, fish, dairy products, fiber, fruits, vegetables, meat, and alcohol).

The studies included randomized controlled trials and observational studies. Most of the meta-analyses found a protective effect for aspirin, which lowered the risk by between 14% and 29% even at doses as low as 75 mg/day, with a dose-response effect of up to 325 mg/day. The certainty of evidence was moderate.

NSAID use was also associated with a protective effect, with a significant 26%-43% decrease in the incidence in colorectal cancer. The optimal duration for the observed protective effect remains unclear. Two meta-analyses suggested that NSAIDs may need to be taken for at least 5 years, although one article suggested a protective effect after the first year. The certainty of evidence was low.

Use of magnesium was found to be protective, with a relative risk (RR) of 0.78-0.87. High intake of folic acid was associated with a significant decrease in risk (RR, 0.85-0.88). The certainty of evidence was low and very low, respectively.

Consumption of dairy products was associated with 13%-19% lower risk for the disease. However, the authors note that, because of the small number of available meta-analyses, the multiplicity of outcomes, and the variety of dairy products, it was not possible to reach any firm conclusions about the amount needed or the duration necessary for a protective effect.

Another dietary item, fiber, was associated with a 22%-43% lower risk. Consumption of fruits and vegetables was associated with up to a 52% lower risk, with an added benefit for every additional 100 g/day increase in intake. Soy intake was also associated with a small but significant decrease in risk (8%-15%).

For many of the other items reviewed, evidence was either weak or no beneficial effect was seen.
 

 

 

Increased risk

Consumption of both meat and alcohol was found to increase the risk for colorectal cancer.

Most of the meta-analyses of observational studies have reported a significant increase in risk (RR, 1.12-1.21) with meat consumption (particularly red and processed) and the incidence of colorectal cancer. Studies of the dose effect reported a 10%-30% increased risk for each increment of 100 g/day of total or red meat.

Alcohol consumption was also associated with a significantly increased risk. The higher the intake, the greater the risk. The risk was evident even at the lowest consumption doses that were investigated (1-2 drinks per day).
 

Balanced for the individual patient

Commenting on the article, Thomas J. George Jr, MD, professor of medicine and director, GI Oncology Program, the University of Florida Health Cancer Center, Gainesville, feels that the take-home message for clinicians and patients alike is that these data help to reinforce behaviors that have already been recommended.

“We know that excessive alcohol and red meat consumption is not healthy, so seeing that there may be a negative effect on colorectal cancer is just more evidence that we should be avoiding that and recommend avoiding that,” said Dr. George. “So yes, I recommend minimizing those, and likewise, a diet that is inclusive of fruits, vegetables, fiber, soy – perhaps as an alternative to meat consumption – is healthier than a diet devoid of these, so again, more reassuring data to support doing what we should already be doing.”

However, he pointed out that there are risks associated with medications such as NSAIDs and aspirin, including bleeding, gastric ulcer formation, and kidney damage. “The risks are low but very real,” Dr. George said. “So I think those recommendations need to be considered on a very individual level, balancing any other risk factors that the patient may have for both colorectal cancer, as well as risks from the medications.”

The study had no outside funding. The authors have disclosed no relevant financial relationships.

“Furthermore, in most cases, we were unable to identify an optimal dose and duration of exposure/intake for any of the products, even in the case of low-dose aspirin and other compounds that have been extensively assessed,” they wrote.

The findings of this new meta-analysis echo previous findings on this issue.

A number of studies, for example, have found varying associations between the consumption of red meat and cancer. The American Institute for Cancer Research and the World Cancer Research Fund have published several reports during the past 10 years on the effect of diet, nutrition, and/or physical activity on risk for several cancer types. Their most recent study, published in 2017, concluded that eating red meat and processed meat may increase the risk for colorectal cancer, as may drinking two or more alcoholic beverages per day.

Another large meta-analysis published earlier this year found that regular use of aspirin reduced the risk for cancers of the digestive tract by 22%-38%, compared with nonuse.
 

Umbrella review

In the latest article in Gut, researchers led by Marc Bardou, MD, PhD, Centre Hospitalier Universitaire de Dijon (France), conducted an umbrella review of systematic reviews and meta-analyses of interventions that assessed chemopreventive products for colorectal cancer in an average-risk population.

A total of 80 meta-analyses of interventional and observational studies were included. The studies investigated a wide range of chemopreventive agents in an average-risk population and the risk for colorectal cancer. Agents included medications (aspirin, NSAIDs, statins), vitamins or supplements (magnesium; calcium; folic acid; vitamin A, B, C, E, and D; beta-carotene; and selenium), and dietary items (coffee, tea, fish, dairy products, fiber, fruits, vegetables, meat, and alcohol).

The studies included randomized controlled trials and observational studies. Most of the meta-analyses found a protective effect for aspirin, which lowered the risk by between 14% and 29% even at doses as low as 75 mg/day, with a dose-response effect of up to 325 mg/day. The certainty of evidence was moderate.

NSAID use was also associated with a protective effect, with a significant 26%-43% decrease in the incidence in colorectal cancer. The optimal duration for the observed protective effect remains unclear. Two meta-analyses suggested that NSAIDs may need to be taken for at least 5 years, although one article suggested a protective effect after the first year. The certainty of evidence was low.

Use of magnesium was found to be protective, with a relative risk (RR) of 0.78-0.87. High intake of folic acid was associated with a significant decrease in risk (RR, 0.85-0.88). The certainty of evidence was low and very low, respectively.

Consumption of dairy products was associated with 13%-19% lower risk for the disease. However, the authors note that, because of the small number of available meta-analyses, the multiplicity of outcomes, and the variety of dairy products, it was not possible to reach any firm conclusions about the amount needed or the duration necessary for a protective effect.

Another dietary item, fiber, was associated with a 22%-43% lower risk. Consumption of fruits and vegetables was associated with up to a 52% lower risk, with an added benefit for every additional 100 g/day increase in intake. Soy intake was also associated with a small but significant decrease in risk (8%-15%).

For many of the other items reviewed, evidence was either weak or no beneficial effect was seen.
 

 

 

Increased risk

Consumption of both meat and alcohol was found to increase the risk for colorectal cancer.

Most of the meta-analyses of observational studies have reported a significant increase in risk (RR, 1.12-1.21) with meat consumption (particularly red and processed) and the incidence of colorectal cancer. Studies of the dose effect reported a 10%-30% increased risk for each increment of 100 g/day of total or red meat.

Alcohol consumption was also associated with a significantly increased risk. The higher the intake, the greater the risk. The risk was evident even at the lowest consumption doses that were investigated (1-2 drinks per day).
 

Balanced for the individual patient

Commenting on the article, Thomas J. George Jr, MD, professor of medicine and director, GI Oncology Program, the University of Florida Health Cancer Center, Gainesville, feels that the take-home message for clinicians and patients alike is that these data help to reinforce behaviors that have already been recommended.

“We know that excessive alcohol and red meat consumption is not healthy, so seeing that there may be a negative effect on colorectal cancer is just more evidence that we should be avoiding that and recommend avoiding that,” said Dr. George. “So yes, I recommend minimizing those, and likewise, a diet that is inclusive of fruits, vegetables, fiber, soy – perhaps as an alternative to meat consumption – is healthier than a diet devoid of these, so again, more reassuring data to support doing what we should already be doing.”

However, he pointed out that there are risks associated with medications such as NSAIDs and aspirin, including bleeding, gastric ulcer formation, and kidney damage. “The risks are low but very real,” Dr. George said. “So I think those recommendations need to be considered on a very individual level, balancing any other risk factors that the patient may have for both colorectal cancer, as well as risks from the medications.”

The study had no outside funding. The authors have disclosed no relevant financial relationships.

A new meta-analysis has largely confirmed what is already known about the lifestyle factors that increase and those that decrease the risk of developing colorectal cancer.

The use of aspirin and nonsteroidal anti-inflammatory drugs (NSAIDs) is associated with a decreased risk for colorectal cancer, the new article concludes. But it also adds a number of other factors that are associated with a decreased risk for the disease, including taking magnesium and folate supplements and eating dairy products, fiber, soy, and fruits and vegetables.

On the other hand, consumption of meat and alcohol was associated with an increased risk for colorectal cancer in almost all of the analyses included in this article.

The study was published online September 28 in Gut.

The scope of under- and overtreatment in older adults with cancer

Article Type

Thu, 12/15/2022 - 17:34

 

Because of physiological changes with aging and differences in cancer biology, caring for older adults (OAs) with cancer requires careful assessment and planning.

Clark Dumontier, MD, of Brigham and Women’s Hospital in Boston, and colleagues sought to define the meaning of the terms “undertreatment” and “overtreatment” for OAs with cancer in a scoping literature review published in the Journal of Clinical Oncology.

Though OAs are typically defined as adults aged 65 years and older, in this review, the authors defined OAs as patients aged 60 years and older.

The authors theorized that a scoping review of papers about this patient population could provide clues about limitations in the oncology literature and guidance about patient management and future research. Despite comprising the majority of cancer patients, OAs are underrepresented in clinical trials.
 

About scoping reviews

Scoping reviews are used to identify existing evidence in a field, clarify concepts or definitions in the literature, survey how research on a topic is conducted, and identify knowledge gaps. In addition, scoping reviews summarize available evidence without answering a discrete research question.

Industry standards for scoping reviews have been established by the Johanna Briggs Institute and Preferred Reporting Items for Systematic Reviews and Meta-analyses extension for scoping reviews. According to these standards, scoping reviews should:

  • Establish eligibility criteria with a rationale for each criterion clearly explained
  • Search multiple databases in multiple languages
  • Include “gray literature,” defined as studies that are unpublished or difficult to locate
  • Have several independent reviewers screen titles and abstracts
  • Ask multiple independent reviewers to review full text articles
  • Present results with charts or diagrams that align with the review’s objective
  • Graphically depict the decision process for including/excluding sources
  • Identify implications for further research.

In their review, Dr. DuMontier and colleagues fulfilled many of the aforementioned criteria. The team searched three English-language databases for titles and abstracts that included the terms undertreatment and/or overtreatment, and were related to OAs with cancer, inclusive of all types of articles, cancer types, and treatments.

Definitions of undertreatment and overtreatment were extracted, and categories underlying these definitions were derived. Within a random subset of articles, two coauthors independently determined final categories of definitions and independently assigned those categories.
 

Findings and implications

To define OA, Dr. DuMontier and colleagues used a cutoff of 60 years or older. Articles mentioning undertreatment (n = 236), overtreatment (n = 71), or both (n = 51) met criteria for inclusion (n = 256), but only 14 articles (5.5%) explicitly provided formal definitions.

For most of the reviewed articles, the authors judged definitions from the surrounding context. In a random subset of 50 articles, there was a high level of agreement (87.1%; κ = 0.81) between two coauthors in independently assigning categories of definitions.

Undertreatment was applied to therapy that was less than recommended (148 articles; 62.7%) or less than recommended with worse outcomes (88 articles; 37.3%).

Overtreatment most commonly denoted intensive treatment of an OA in whom harms outweighed the benefits of treatment (38 articles; 53.5%) or intensive treatment of a cancer not expected to affect the OA during the patient’s remaining life (33 articles; 46.5%).

Overall, the authors found that undertreatment and overtreatment of OAs with cancer are imprecisely defined concepts. Formal geriatric assessment was recommended in just over half of articles, and only 26.2% recommended formal assessments of age-related vulnerabilities for management. The authors proposed definitions that accounted for both oncologic factors and geriatric domains.
 

 

 

Care of individual patients and clinical research

National Comprehensive Cancer Network (NCCN) guidelines for OAs with cancer recommend initial consideration of overall life expectancy. If a patient is a candidate for cancer treatment on that basis, the next recommended assessment is that of the patient’s capacity to understand the relevant information, appreciate the underlying values and overall medical situation, reason through decisions, and communicate a choice that is consistent with the patient’s articulated goals.

In the pretreatment evaluation of OAs in whom there are no concerns about tolerance to antineoplastic therapy, NCCN guidelines suggest geriatric screening with standardized tools and, if abnormal, comprehensive geriatric screening. The guidelines recommend considering alternative treatment options if nonmodifiable abnormalities are identified.

Referral to a geriatric clinical specialist, use of the Cancer and Aging Research Group’s Chemo Toxicity Calculator, and calculation of Chemotherapy Risk Assessment Scale for High-Age Patients score are specifically suggested if high-risk procedures (such as chemotherapy, radiation, or complex surgery, which most oncologists would consider to be “another day in the office”) are contemplated.

The American Society of Clinical Oncology (ASCO) guidelines for geriatric oncology are similarly detailed and endorse similar evaluations and management.

Employing disease-centric and geriatric domains

Dr. DuMontier and colleagues noted that, for OAs with comorbidity or psychosocial challenges, surrogate survival endpoints are unrelated to quality of life (QOL) outcomes. Nonetheless, QOL is valued by OAs at least as much as survival improvement.

Through no fault of their own, the authors’ conclusion that undertreatment and overtreatment are imperfectly defined concepts has a certain neutrality to it. However, the terms undertreatment and overtreatment are commonly used to signify that inappropriate treatment decisions were made. Therefore, the terms are inherently negative and pejorative.

As with most emotionally charged issues in oncology, it is ideal for professionals in our field to take charge when deficiencies exist. ASCO, NCCN, and the authors of this scoping review have provided a conceptual basis for doing so.

An integrated oncologist-geriatrician approach was shown to be effective in the randomized INTEGERATE trial, showing improved QOL, reduced hospital admissions, and reduced early treatment discontinuation from adverse events (ASCO 2020, Abstract 12011).

Therefore, those clinicians who have not formally, systematically, and routinely supplemented the traditional disease-centric endpoints with patient-centered criteria need to do so.

Similarly, a retrospective study published in JAMA Network Open demonstrated that geriatric and surgical comanagement of OAs with cancer was associated with significantly lower 90-day postoperative mortality and receipt of more supportive care services (physical therapy, occupational therapy, speech and swallow rehabilitation, and nutrition services), in comparison with management from the surgical service only.

These clinical and administrative changes will not only enhance patient management but also facilitate the clinical trials required to clarify optimal treatment intensity. As that occurs, we will be able to apply as much precision to the care of OAs with cancer as we do in other areas of cancer treatment.

His clinical and research interests were focused on breast and lung cancers, as well as expanding clinical trial access to medically underserved populations. He is based in St. Louis. He has no conflicts of interest.

Global stomach cancer deaths decline as colorectal cancer deaths stagnate, rise

Article Type
Changed
Thu, 12/15/2022 - 17:34

 

A global analysis of premature deaths from noncommunicable diseases (NCDs) has shown mixed results for gastrointestinal (GI) cancers.

The data suggest fewer people are dying from stomach cancer, but in some countries, the risk of colorectal cancer death is increasing or declining much more slowly than other causes of premature death.

As for other cancers, in more than half of the countries analyzed, the risk of liver and prostate cancer death is on the rise in men, and the risk of lung cancer death is on the rise in women.

The global decrease in the risk of stomach cancer death may be explained by the fact that stomach cancer’s main cause is Helicobacter pylori infection, which correlates with general food hygiene, the study’s corresponding author Majid Ezzati, PhD, professor of global environmental health at Imperial College London, said in an interview.

“Factors such as more widespread electrification and refrigeration tend to drive the rates down,” he explained.

Dr. Ezzati and colleagues detailed their findings in the second edition of the NCD Countdown 2030 report, recently published in The Lancet.

The report revolves around the Sustainable Development Goal (SDG) target 3.4, which is to reduce premature deaths from NCDs by one-third between 2015 and 2030. The causes of death include cancer, cardiovascular disease, chronic respiratory disease, and diabetes, which are collectively known as NCD4. “Premature” deaths are defined as deaths in people aged 30-70 years.

SDG target 3.4 is still attainable, according to Dr. Ezzati and colleagues. However, their report showed that many countries are falling short of this goal.

The findings come from an analysis of 2016 World Health Organization global estimate data on age-, sex-, and cause-specific mortality for 176 countries and territories with at least 200,000 inhabitants. Mathematical modeling was used to assess the number of approaches countries used to accelerate declines in mortality.
 

Results of the analysis

“Trends in the risk of death from 2010 to 2016 varied considerably among NCD4 causes of death,” Dr. Ezzati and colleagues wrote.

Stomach cancer, ischemic and hemorrhagic stroke, ischemic heart disease, and chronic respiratory diseases had the fastest rates of decline among risks of premature death.

In fact, stomach cancer was the fastest declining cause of death in 45 countries (25.6%) among men and in 40 countries (22.7%) among women.

On the other hand, the risk of premature death from colorectal, liver, breast, prostate, and other cancers declined more slowly than the risk of premature death from other NCDs.

The risk of death from colorectal, liver, and prostate cancers in men and lung cancer in women rose in more than 50% of the countries surveyed.

“The median annual rate of change in the probability of dying prematurely from various causes ranged from +0.2% per year for lung cancer to –2.5% per year for hemorrhagic stroke in women, and from +0.5% per year for colorectal cancer to –1.8% per year for hemorrhagic stroke in men,” the investigators summarized.
 

Explaining the GI cancer results

“There are dramatic differences between the upper and lower GI tract, both in terms of anatomy/embryologic origin but also in terms of exposures,” observed Mark Lewis, MD, medical director of the gastrointestinal oncology program at Intermountain Healthcare in Salt Lake City, in an interview.

H. pylori infection, family history, and diet factor into stomach cancer risk, Dr. Lewis said.

While family history isn’t modifiable, “we are much better now at identifying and eradicating the potentially carcinogenic H. pylori bacterium. In terms of diet, the advent of modern refrigeration has made the prevalence of heavily salted/preserved foods decline,” he added.

A 14-day course of treatment (with a proton pump inhibitor and antibiotics) can eliminate H. pylori, Dr. Lewis continued. “The prophylactic effect against gastric cancer is massive, cutting risk by roughly half,” he said.

At least in the United States, colorectal cancer rates have declined in people 50 years and older, but rates have risen sharply in younger age groups, increasing by 2% annually in the last decade, according to statistics in CA: A Cancer Journal for Clinicians.

“One prevailing theory is prior antibiotic prescriptions [even in childhood] might perturb the microbiome of the lower GI tract and predispose to cancer,” Dr. Lewis said, pointing to a recent study in the British Journal of Cancer that identified an association between repeated antibiotic use and colorectal cancer.
 

Reducing NCD deaths

Dr. Ezzati and colleagues said six high-income countries – Denmark, Luxembourg, New Zealand, Norway, Singapore, and South Korea – are likely to meet SDG target 3.4 if they maintain or exceed average rates of decline seen during 2010-2016. Seventeen countries are on track to reach the target for women, and 15 countries are on track for men.

High-income countries in Asia-Pacific, western Europe, Australasia, and Canada have seen the lowest NCD4 mortality risk, whereas low- and middle-income countries in sub-Saharan Africa and men in central Asia and eastern Europe have seen the highest risk.

“To move forward, we must learn from those countries that are doing well and replicate their strategies to NCD prevention and healthcare,” Dr. Ezzati said in a statement. “Our analysis shows that every country still has options to achieve SDG target 3.4, but they need to address multiple diseases and have strong health systems.”

Increasing access to effective cancer screening and diagnosing and treating cancers earlier could help reduce long-term health consequences and premature deaths from cancer, according to Dr. Ezzati and colleagues. Screening would help even the playing field on cancer diagnosis and survival rates between higher-income countries and low- and middle-income countries.

“This approach will allow earlier diagnosis during precancerous or early stages of disease, followed by treatment of those cancers with effective treatment,” the authors stated.

Tobacco and alcohol interventions and increasing access to quality primary care would also help tamp down on NCD-related deaths.

The authors acknowledged that low-income countries, which may be struggling with other health crises such as COVID-19 and Ebola, may find it a challenge to stage such interventions.

“COVID-19 has exposed how a failure to invest in effective public health to prevent NCDs and provide health care for people living with NCDs can come back to bite us,” said Katie Dain, CEO of the NCD Alliance.

“The good news is that all countries can still meet the 2030 targets, with sound policies and smart investments. NCD prevention and treatment can no longer be seen a ‘nice to have.’ It must be considered as part of pandemic preparedness,” she added.

COVID-19 should serve as an impetus for governments to invest in healthier lifestyle and diet habits and curb alcohol and tobacco use, according to an editorial in The Lancet related to the analysis.

The current report updates 2018’s first NCD Countdown Report, which linked NCD4 conditions to approximately 32 million or 80% of NCD deaths. Unlike the recent report, 2018’s data didn’t focus on specific diseases.

The current report was funded by Research England. Dr. Ezzati received a charitable grant from the AstraZeneca Young Health Programme and personal fees from Prudential and Scor, outside of this report. None of the other authors reported competing interests. Dr. Lewis has no relevant disclosures except that he is a commentator for Medscape, which is owned by the same parent company as MDedge.

A global analysis of premature deaths from noncommunicable diseases (NCDs) has shown mixed results for gastrointestinal (GI) cancers.

The data suggest fewer people are dying from stomach cancer, but in some countries, the risk of colorectal cancer death is increasing or declining much more slowly than other causes of premature death.

As for other cancers, in more than half of the countries analyzed, the risk of liver and prostate cancer death is on the rise in men, and the risk of lung cancer death is on the rise in women.

The global decrease in the risk of stomach cancer death may be explained by the fact that stomach cancer’s main cause is Helicobacter pylori infection, which correlates with general food hygiene, the study’s corresponding author Majid Ezzati, PhD, professor of global environmental health at Imperial College London, said in an interview.

“Factors such as more widespread electrification and refrigeration tend to drive the rates down,” he explained.

Dr. Ezzati and colleagues detailed their findings in the second edition of the NCD Countdown 2030 report, recently published in The Lancet.

Promising Trends Seen in AIDS-Associated NHL

Article Type

Patients are doing as well as HIV-negative counterparts in some cases, hematologist says at virtual AVAHO meeting.

Prognoses for patients with AIDS-associated, non-Hodgkin lymphomas (AIDS-NHLs) have improved dramatically as HIV/AIDS has become easier to treat, and “we’re actually seeing patients with long-term remissions that are translating to cure,” a hematologist told colleagues at the virtual 2020 annual meeting of the Association of VA Hematology/Oncology (AVAHO).

“Even those with low CD4 counts initially have more chance of survival compared to the historic patients in the pre-HAART [highly active antiretroviral therapy] era,” explained Erin Reid, MD, MS, of the University of California at San Diego Moores Cancer Center. “They’re seeing complete-response rates and overall-survival rates that are nearly matching what we’re seeing in the non-HIV lymphoma cases. And aggressive infection prophylaxis has seemed to mitigate some of the infectious complications.”

Still, Reid said, a severe form of AIDS-NHL continues to have very poor outcomes, although specific regimens appear to be brightening the picture somewhat.

According to Dr. Reid, AIDS-NHLs are the most common malignancy in the HIV-positive population, and patients with these cancers are more likely to have aggressive lymphomas. These patients are also more likely to have lymphomas associated with Epstein-Barr virus—40 to 80%, depending on the subtype of lymphoma—and Kaposi sarcoma-associated herpesvirus (also known as human herpesvirus-8, or HHV8).

“These viruses are driving these cancers, and it begs the question of whether there’s something we can do to target these viruses within these cancer cells in a way that’s therapeutic,” she said.

Compared with the non-HIV population, patients with AIDS-NHL “are much more likely to present with advanced stage, extranodal disease and central nervous system involvement,” she said.

 

HAART Benefits

It’s become clear that HIV control via HAART has benefits in terms of higher tolerance of chemotherapy doses—“we’re able to use more full or traditional dose regimens”—and perhaps cancer suppression too, she said. A 2013 meta-analysis “favored concurrent therapy with chemotherapy [and HAART]. This has become our recommended standard of care for virtually all cases, except the very rare ones where you cannot find a regimen that is compatible from a PK [pharmacokinetics] standpoint.”

Reid also noted that the HAART era has changed the role of CD4 counts in AIDS-NHLs. “While CD4 count still has some predictive value, its impact on mortality appears attenuated,” she said.

 

EPOCH Treatment

With regard to treatment, she emphasized the importance of HAART: “We would recommend concurrent HAART whenever possible with chemotherapy, or start it immediately afterward.”

Aggressive infection prophylaxis also is recommended through granulocyte colony-stimulating factor and agents to target threats from pneumocystis jiroveci pneumonia, gram negative rods, and varicella-zoster virus. “I’ve moved away from fungal prophylaxis over the years, only dealing with it if there’s a known fungal infection,” she said.

As for treatment of AIDS-NHL, Reid Suggested that research supports the EPOCH regimen --etoposide, prednisone, vincristine, cyclophosphamide, and doxorubicin. However, “we still need strategies for refractory and relapsed disease,” she said.

Reid noted that she has started to see more plasmablastic cases, although her experience is anecdotal. Plasmablastic lymphoma is much more common in the HIV-positive setting, she said.

Lifespans are poor for these patients, with many failing to live for a year. But research hints that the prognosis in AIDS-NHL patients on HAART may actually be better than in the non-HIV population, she said.

A trial published in September 2020, in fact, reports that 87% of 15 patients with AIDS-associated plasmablastic lymphoma survived for at least one year on the EPOCH regimen. Overall, the study found that “people with a collection of HIV-associated lymphomas were doing well overall with the EPOCH backbone,” Reid explained.

Reid reported no relevant disclosures.

VA Hematologist/Oncologist highlights 4 bleeding disorders and offers treatment recommendations during presentation for virtual AVAHO meeting.

Although it may seem that veterans would have a very low risk of bleeding disorders since they were medically cleared for military service, a hematologist/oncologist cautioned that veterans might indeed suffer from both inherited and noninherited forms of these conditions. At the virtual 2020 annual meeting of the Association of VA Hematology/Oncology (AVAHO) Bethany Samuelson Bannow, MD, of Oregon Health & Science University’s Knight Cancer Institute urged colleagues to understand the diagnosis and treatment of bleeding disorders.

            “Most importantly, even though these are patients you probably don’t see on a regular basis, you are never alone,” since colleagues are available to help, she said. Samuelson Bannow treats patients at US Department of Veterans Affairs (VA) Portland Health Care System and used her presentation to focus on 4 types of bleeding disorders. A summary of her perspective and recommendations follows.

Acquired hemophilia: Watch for Infections

Acquired hemophilia affects only an estimated 1.3 to 1.5 in 1 million people, but VA physicians may see it more often since it affects an older population (median age is 78 years), Samuelson Bannow said. “I’ve seen about 4 cases in the last 2 years,” she said. “I’m not sure if we’re a magnet, but it does come up.”

The diagnosis is based on laboratory findings, and a lack of personal or family history of coagulopathy is key, she said. Twenty percent or more of patients older than 65 years die from the disorder, but bleeding usually isn’t the cause. Instead, patients tend to die from infections, she said.

Initial treatment must focus on stopping the bleeding, she said. The new drug porcine antihemophilic factor (recombinant)—Obizur—“is very helpful” and is Samuelson Bannow’s first choice, but it may not widely available at all VA medical centers. Recombinant FVIIa (NovoSeven) and activated prothrombin complex concentrate (Feiba) also are options.

            “The goal is to overpower the clotting cascade and get that burst of thrombin generation that you need to get the bleeding under control. Titrate to the amount of bleeding the patient is having, and make sure you’re doing local control as well,” Samuelson Bannow said. She added that the 2 agents may not work depending on the patient. Neither is preferred and both may be appropriate. “There’s no real reason to pick one over the other beyond convenience and availability.”

            There’s another “equally important component of management,” she said: Inhibitor eradication. “The only way to do this is with immune suppression. You’re going to have to suppress the immune system to get rid of the inhibitor. That’s why we see such high rates of death because we have to use heavy-hitter immunosuppressants.”

            Treatment options include steroids and cyclophosphamide (a common first-line option), rituximab, calcineurin inhibitors, and mycophenolate mofetil. “Just be aware that there is an increased risk of infection with these agents,” she said. “You want to see a decrease in the titer of your inhibitor. This can take 3 or more weeks, and it can take longer for it to disappear entirely. Look for normalized factor VIII level and absent inhibitor.”

            She added: “I tend to do a slow taper, one agent at a time, over the course of weeks. If you see a return of the inhibitor, you can ramp back up as needed. Continue to monitor for a year or more since patients are at high risk of recurrence.”

Acquired von Willebrand Syndrome: Fix the Associated Conditions

Acquired von Willebrand Syndrome is another rare bleeding disorder that may appear in veterans “since it’s associated with a lot of conditions that we see in the VA,” such as heart disorders, solid tumors, vascular malformations, and lymphoproliferative and myeloproliferative disorders, Samuelson Bannow said.

            As with acquired hemophilia, the key is to focus on controlling the bleeding, she said. Then, she advised, focus on the associated condition: “Correct the underlying disorder: Treat the malignancy, address the [cardiac] shear stress, correct hypothyroidism, correct the cardiac defects.”

Inherited Hemophilia: Don’t Rule It Out

It’s possible to “sneak through” military medical screening with undiagnosed inherited bleeding disorders, Dr. Samuelson Bannow said. That’s because service members may have never had an injury that triggered abnormal bleeding, she said. “You can see how someone could slip into the military with a [low clotting factor level]. The classic presentation is going to be joint bleeds and abnormalities. These can be traumatic and spontaneous without any kind of an injury,” she said.

            A general rule for these patients is to “replace what’s missing, and 100% is always normal.” The 100% refers to clotting factor level. She recommended reviewing 2013 guidelines for the treatment of the disorder.

Inherited von Willebrand Syndrome: Ask About Tonsillectomies

Inherited von Willebrand Syndrome is more common in women than it is in men. Bleeding “will primarily be mucocutaneous and trauma-induced,” said. Samuelson Bannow. She recommended asking patients if they have had a tonsillectomy and, if so, did they suffer from unusual bleeding. “If they did not have excessive bleeding, it’s a pretty good sign their hemostasis is good.”

            She recommends a nasal spray drug called desmopressin (DDAVP, Stimate) for management. “It’s critical to know that you must test for efficacy first,” she said. “One of the most common mistakes that people make is that they may give patients DDAVP before surgery without knowing if it works or not. It doesn’t work for every patient.” She typically avoids this drug in patients aged > 65 years, or even > 60 years, due to increased thrombosis risk.

            Recombinant von Willebrand factor (Vonvendi) is a “very helpful drug at patients at increased risk of thrombosis,” she said. However, she noted that the drug, at last check, is not on the VA’s formulary.

            At the end of her presentation, Samuelson Bannow urged colleagues to contact specialized Hemophilia Treatment Centers (HTCs) near them: “Follow this link, find an HTC [Hemophilia Treatment Center] near you, and create a partnership.”

Samuelson Bannow reported no relevant disclosures.

Two new protein biomarkers may serve as prognostic indicators for outcomes in CLL

Two new protein biomarkers may serve as prognostic indicators for outcomes in chronic lymphocytic leukemia (CLL) patients, according to the results of a proteomic assessment of patients’ serum compared to their event-free survival (EFS).

The results were published in Experimental Hematology.

The study attempted to validate the prognostic ability of known proteomic markers measured pretreatment and to search for new proteomic markers that might be related to treatment response in CLL, according to Fatemeh Saberi Hosnijeh, MD, of Erasmus MC, University Medical Center, Rotterdam, The Netherlands, and colleagues.

Baseline serum samples were taken from 51 CLL patients who were then treated with chemoimmunotherapy. The samples were analyzed for 360 proteomic markers, and those results were compared with patient EFS.

Study subjects were selected from patients enrolled in the HOVON 109 clinical trial, a phase 1/2 trial designed to assess the efficacy and safety of first-line therapy involving chlorambucil, rituximab,and lenalidomide in elderly patients and young frail patients with advanced CLL.

The patients assessed comprised 30 men and 21 women, and the median EFS for all patients was 23 months (ranging from 1.25 to 60.9 months).
 

Promising biomarkers

The researchers found that patients who had high serum levels of the proteins sCD23 (P = .026), sCD27 (P = .04), the serine peptidase inhibitor SPINT1 (P = .001), and the surface antigen protein LY9 (P = .0003) had a shorter EFS than those with marker levels below the median.

“Taken together, our results validate the prognostic impact of sCD23 and highlight SPINT1 and LY9 as possible promising markers for treatment response in CLL patients,” the researchers stated.

“Despite the relatively small number of available cases, which had an impact on statistical power, our pilot study identified SPINT1 and LY9 as promising independent prognostic proteomic markers next to sCD23 and sCD27 in patients treated for CLL. Further studies with larger sample sizes are required to validate these results,” the researchers concluded.

This research was supported by a grant from Gilead Sciences and an EU TRANSCAN/Dutch Cancer Society grant. The authors declared that they had no conflicts of interest.

Lorlatinib: Another first-line option for ALK-positive NSCLC?

Article Type
Changed
Tue, 09/29/2020 - 09:47

 

First-line lorlatinib significantly prolonged progression-free survival (PFS) when compared with crizotinib in advanced ALK-positive non–small cell lung cancer (NSCLC), according to an interim analysis of the phase 3 CROWN trial.

Lorlatinib also produced a higher overall and intracranial response rate, prolonging progression to CNS disease.

These findings “support the use of lorlatinib as a highly effective first-line therapy for patients with advanced ALK-positive NSCLC,” said Benjamin Solomon, MBBS, PhD, of the Peter MacCallum Cancer Centre in Melbourne.

“The CROWN study clearly establishes lorlatinib as another option” among other first-line ALK inhibitors, Dr. Solomon said when presenting the findings at the European Society for Medical Oncology Virtual Congress 2020.

“We now have multiple options for first-line treatment of patients with ALK-positive lung cancer,” noted study discussant Christine Lovly, MD, PhD, a medical oncologist and associate professor at Vanderbilt University Medical Center in Nashville, Tenn.

The question now, she said, is how to choose among these options. The drugs have all bested crizotinib in trials but haven’t gone head to head against one another.
 

Lorlatinib and CROWN

Lorlatinib is currently approved in the United States to treat ALK-positive metastatic NSCLC that has progressed on crizotinib and at least one other ALK inhibitor. Lorlatinib was granted accelerated approval for this indication based on response rate and duration.

The CROWN study was intended to support the conversion to full approval, according to Pfizer, which is developing both lorlatinib and crizotinib. Pfizer also plans to use the results of CROWN to seek a first-line indication for lorlatinib in NSCLC.

CROWN enrolled 296 patients with stage IIIB/IV ALK-positive NSCLC who had received no prior systemic treatment. Patients with asymptomatic treated or untreated CNS metastases were eligible.

There were 149 patients randomized to lorlatinib at 100 mg daily and 147 randomized to crizotinib at 250 mg twice daily. Five patients in the crizotinib arm were included in the analysis but were not treated, Dr. Solomon said.

The median age was 61 years in the lorlatinib arm and 56 years in the crizotinib arm. Nearly all patients were White (48% in the lorlatinib arm and 49% in the crizotinib arm) or Asian (44% in both arms). A majority of patients were women (56% in the lorlatinib arm and 62% in the crizotinib arm), and more than half said they never smoked (54% in the lorlatinib arm and 64% in the crizotinib arm).
 

Response and PFS

According to blinded independent central review, the objective response rate was 76% with lorlatinib (113/149) and 58% with crizotinib (85/147). There were four complete responses with lorlatinib and none with crizotinib.

Among patients who had measurable or nonmeasurable brain metastases at baseline, the intracranial ORR was 66% with lorlatinib (25/38) and 20% (8/40) with crizotinib. In patients with only measurable brain metastases at baseline, the intracranial ORR was 82% with lorlatinib (14/17) and 23% with crizotinib (3/13).

The 12-month PFS rate was 78% in the lorlatinib arm and 39% in the crizotinib arm. The median PFS was 9.3 months in the crizotinib arm but was not reached in the lorlatinib arm, which “corresponded to a 72% reduction in the risk of death or progression [hazard ratio, 0.21; P < .001],” Dr. Solomon said.

“[T]he PFS for alectinib in the first line is approximately 3 years,” Dr. Lovly noted. “We anxiously await additional data for lorlatinib to see how long the PFS will be.”

The median time to intracranial progression was 16.6 months in the crizotinib arm but was not reached in the lorlatinib arm (HR, 0.07; P < .001).

“These data indicate the ability of lorlatinib not only to delay the progression of existing brain metastases, but also to prevent the development of new brain metastases,” Dr. Solomon said.

Dr. Lovly noted that the efficacy of lorlatinib in the brain is “quite compelling,” but other ALK inhibitors have demonstrated similar results.

As for overall survival, the data are still immature. The median overall survival was not reached with lorlatinib or crizotinib (HR, 0.72).
 

 

 

Toxicity

Dr. Solomon noted that lorlatinib “does have a different toxicity profile, compared to other ALK inhibitors.” Specifically, lorlatinib is associated with hypercholesterolemia and hypertriglyceridemia, which have not been seen with other ALK inhibitors.

Lorlatinib is also associated with neurocognitive problems, including inattention, memory impairment, and mild confusion. Mood effects include emotional lability – “someone watching a movie might burst into tears when they wouldn’t have otherwise,” Dr. Solomon said – as well as anxiety and depression.

“So it’s important to tell not just the patient but their family about these things so that they identify when [the events] happen,” Dr. Solomon said. “That’s key because [the events are] completely reversible when you stop the drug. With dose interruption, those effects will resolve.”

Other adverse events that were more common with lorlatinib (a 10% or greater difference in frequency from crizotinib) included edema, weight gain, and peripheral neuropathy. Diarrhea, nausea, fatigue, vision disorders, constipation, and increased liver enzymes were more common with crizotinib. Grade 3-4 adverse events led to discontinuation in fewer than 10% of patients in each arm.

The study was funded by Pfizer, and the investigators included employees. Dr. Solomon is an adviser for Pfizer and other companies, and Dr. Lovly’s industry ties included being both an advisor and speaker for Pfizer.

These findings “support the use of lorlatinib as a highly effective first-line therapy for patients with advanced ALK-positive NSCLC,” said Benjamin Solomon, MBBS, PhD, of the Peter MacCallum Cancer Centre in Melbourne.

“The CROWN study clearly establishes lorlatinib as another option” among other first-line ALK inhibitors, Dr. Solomon said when presenting the findings at the European Society for Medical Oncology Virtual Congress 2020.

“We now have multiple options for first-line treatment of patients with ALK-positive lung cancer,” noted study discussant Christine Lovly, MD, PhD, a medical oncologist and associate professor at Vanderbilt University Medical Center in Nashville, Tenn.

The question now, she said, is how to choose among these options. The drugs have all bested crizotinib in trials but haven’t gone head to head against one another.
 

Lorlatinib and CROWN

Lorlatinib is currently approved in the United States to treat ALK-positive metastatic NSCLC that has progressed on crizotinib and at least one other ALK inhibitor. Lorlatinib was granted accelerated approval for this indication based on response rate and duration.

The CROWN study was intended to support the conversion to full approval, according to Pfizer, which is developing both lorlatinib and crizotinib. Pfizer also plans to use the results of CROWN to seek a first-line indication for lorlatinib in NSCLC.

CROWN enrolled 296 patients with stage IIIB/IV ALK-positive NSCLC who had received no prior systemic treatment. Patients with asymptomatic treated or untreated CNS metastases were eligible.

There were 149 patients randomized to lorlatinib at 100 mg daily and 147 randomized to crizotinib at 250 mg twice daily. Five patients in the crizotinib arm were included in the analysis but were not treated, Dr. Solomon said.

The median age was 61 years in the lorlatinib arm and 56 years in the crizotinib arm. Nearly all patients were White (48% in the lorlatinib arm and 49% in the crizotinib arm) or Asian (44% in both arms). A majority of patients were women (56% in the lorlatinib arm and 62% in the crizotinib arm), and more than half said they never smoked (54% in the lorlatinib arm and 64% in the crizotinib arm).
 

Response and PFS

According to blinded independent central review, the objective response rate was 76% with lorlatinib (113/149) and 58% with crizotinib (85/147). There were four complete responses with lorlatinib and none with crizotinib.

Among patients who had measurable or nonmeasurable brain metastases at baseline, the intracranial ORR was 66% with lorlatinib (25/38) and 20% (8/40) with crizotinib. In patients with only measurable brain metastases at baseline, the intracranial ORR was 82% with lorlatinib (14/17) and 23% with crizotinib (3/13).

The 12-month PFS rate was 78% in the lorlatinib arm and 39% in the crizotinib arm. The median PFS was 9.3 months in the crizotinib arm but was not reached in the lorlatinib arm, which “corresponded to a 72% reduction in the risk of death or progression [hazard ratio, 0.21; P < .001],” Dr. Solomon said.

“[T]he PFS for alectinib in the first line is approximately 3 years,” Dr. Lovly noted. “We anxiously await additional data for lorlatinib to see how long the PFS will be.”

The median time to intracranial progression was 16.6 months in the crizotinib arm but was not reached in the lorlatinib arm (HR, 0.07; P < .001).

“These data indicate the ability of lorlatinib not only to delay the progression of existing brain metastases, but also to prevent the development of new brain metastases,” Dr. Solomon said.

Dr. Lovly noted that the efficacy of lorlatinib in the brain is “quite compelling,” but other ALK inhibitors have demonstrated similar results.

As for overall survival, the data are still immature. The median overall survival was not reached with lorlatinib or crizotinib (HR, 0.72).
 

 

 

Toxicity

Dr. Solomon noted that lorlatinib “does have a different toxicity profile, compared to other ALK inhibitors.” Specifically, lorlatinib is associated with hypercholesterolemia and hypertriglyceridemia, which have not been seen with other ALK inhibitors.

Lorlatinib is also associated with neurocognitive problems, including inattention, memory impairment, and mild confusion. Mood effects include emotional lability – “someone watching a movie might burst into tears when they wouldn’t have otherwise,” Dr. Solomon said – as well as anxiety and depression.

“So it’s important to tell not just the patient but their family about these things so that they identify when [the events] happen,” Dr. Solomon said. “That’s key because [the events are] completely reversible when you stop the drug. With dose interruption, those effects will resolve.”

Other adverse events that were more common with lorlatinib (a 10% or greater difference in frequency from crizotinib) included edema, weight gain, and peripheral neuropathy. Diarrhea, nausea, fatigue, vision disorders, constipation, and increased liver enzymes were more common with crizotinib. Grade 3-4 adverse events led to discontinuation in fewer than 10% of patients in each arm.

The study was funded by Pfizer, and the investigators included employees. Dr. Solomon is an adviser for Pfizer and other companies, and Dr. Lovly’s industry ties included being both an advisor and speaker for Pfizer.
