Severe health conditions decrease among childhood cancer survivors
CHICAGO—The 15-year cumulative incidence of severe health conditions for survivors of childhood cancer has decreased over the past 30 years, from 12.7% for those diagnosed in the 1970s to 10.1% and 8.9% for those diagnosed in the 1980s and 1990s, respectively. And the decreases were greatest for patients with Wilms’ tumor and Hodgkin lymphoma (HL), followed by patients with astrocytoma, non-Hodgkin lymphoma (NHL), and acute lymphoblastic leukemia (ALL).
Investigators of the Childhood Cancer Survivor Study (CCSS) undertook a retrospective cohort analysis of children aged 0 – 14 years diagnosed with cancer between 1970 and 1999. Their goal was to determine whether cancer therapy modifications have maintained cure rates while decreasing the risk of late effects of therapy.
Todd M. Gibson, PhD, of St Jude Children’s Research Hospital in Memphis, Tennessee, presented the findings at the 2017 annual meeting of the American Society for Clinical Oncology (ASCO) as abstract LBA10500.
Researchers analyzed data from 23,600 childhood cancer survivors in the CCSS who were alive 5 years after diagnosis. The patients had leukemia, lymphoma, CNS malignancies, Wilms tumor, neuroblastoma, or soft-tissue/bone sarcoma.
Dr Gibson noted that while 83% of children with a malignancy achieve a 5-year survival, more than half develop at least one severe, disabling, life-threatening health condition by age 50.
The survivors were a median age at last follow-up of 28 years (range, 5-63) and the median time since diagnosis was 21 years (range, 5-43).
The investigators found significant decreases in severe health conditions in 6 diagnostic groups:
- Wilms tumor, decreased from 13% to 5% (P<0.0001)
- HL, decreased from 18% to 11% (P<0.0001)
- Astrocytoma, decreased from 15% to 9% (P=0.004)
- NHL, decreased from 10% to 6% (P=0.04)
- ALL, decreased from 9% to 7% (P=0.002)
- Ewings sarcoma, decreased from 19% to 10% (P=0.01)
They found no reductions in subsequent severe health conditions among survivors of neuroblastoma, acute myeloid leukemia (AML), soft tissue sarcoma, or osteosarcoma.
The investigators believe the decreases were driven mainly by a reduced incidence of endocrine conditions, subsequent malignant neoplasms, gastrointestinal and neurological conditions, but not cardiac or pulmonary conditions.
They also analyzed the reduction in treatment intensities by decade for different diseases and found they correlated with the reduced incidence of serious chronic health conditions by 15 years after diagnosis.

Single-dose RT suffices for treatment of spinal cord compression due to mets
CHICAGO – A single dose of radiation therapy appears to work as well as multiple doses given over a week for treating spinal cord compression due to metastatic cancer, according to findings of the SCORAD III trial reported at the annual meeting of the American Society of Clinical Oncology.
“There is no standard radiotherapy schedule,” first author Peter Hoskin, MD, FCRP, FRCR, an oncologist at the Mount Vernon Cancer Centre in Middlesex, England, noted in a press briefing. “A range of radiation doses are used internationally, from single doses of 8 to 10 Gy ranging up to 4 weeks of treatment delivering 40 Gy.”
The noninferiority phase III trial enrolled nearly 700 patients in the United Kingdom and Australia with spinal cord compression due to metastases, the majority of whom were able to walk at baseline. They were randomized evenly to receive either 8 Gy of radiation in a single fraction or 20 Gy split into five fractions given over consecutive days.
Results showed that at 8 weeks, more than two-thirds of patients in each group were able to walk, the trial’s primary endpoint. The lower bound of the confidence interval for the difference between groups fell just outside the trial’s margin for noninferiority.
Additionally, the two groups were statistically indistinguishable with respect to median overall survival, bowel and bladder function, and the rate of grade 3 or 4 toxicity.
“A single dose of 8 Gy is as effective as 20 Gy in five fractions for a range of clinically relevant endpoints, particularly ambulatory status, both at 8 weeks and indeed at all time points between 1 week and 12 weeks,” Dr. Hoskin summarized. The trial also underscores the importance of early diagnosis, as the majority of patients who were ambulatory initially remained so with radiation therapy, regardless of dosing schedule.
“A single dose of radiotherapy in our minds is now recommended in this setting. It has major advantages for these patients,” he maintained. “An important thing to realize is that these patients had a very short survival; median survival in this study was only 13 weeks. A single dose has enormous advantages in those patients with short survival times, and of course, it is increasingly cost effective.”
Findings in context
The trial population was not fully representative of all patients with spinal cord compression due to metastases, with underrepresentation of some cancers, such as breast cancer, and the modest survival, Dr. Hoskin acknowledged.
Some patients on the trial have survived for many months and even years, he noted. “We have looked at patients at longer times, although it was not in the protocol, and there was no obvious difference [in outcomes]. But there is some evidence to suggest that for the longer-surviving patients, a more prolonged fractionation may be appropriate, although clearly that needs to be investigated properly in a formal randomized trial.”
“This is the first study that really shows equal outcomes in terms of meaningful benefits for patients with a single dose of radiotherapy versus a much longer course, allowing patients to spend more time with their families, more time doing the things they want to do,” commented ASCO Expert Joshua A. Jones, MD, MA, of the Hospital of the University of Pennsylvania in Philadelphia.
“We still have work to do to figure out for patients who have longer than this average survival of 3 months what is the most appropriate regimen,” he agreed. “But for many patients, this is going to provide tremendous benefit with the idea that sometimes, less really is more.”
Study details
SCORAD III, which was funded by Cancer Research UK, enrolled 688 patients with metastatic prostate (44%), lung (18%), breast (11%), and gastrointestinal (11%) cancers.
At baseline, 66% were able to walk without or with an aid (ambulatory status 1 or 2), whereas the rest were unable to walk but still had some limb power (ambulatory status 3) or had flaccid paraplegia (ambulatory status 4).
At 8 weeks, the proportion of patients with ambulatory status 1 or 2 was 69.5% in the group who received the 8-Gy single-dose radiation therapy and 73.3% in the group who received the 20-Gy multidose radiation therapy, for a risk difference of –3.78%, reported Dr. Hoskin.
The 90% confidence interval for the difference between groups of –11.85% to 4.28% slightly exceeded the trial’s predefined 11% margin for noninferiority.
Among patients having ambulatory status 1 or 2 at baseline, the proportion maintaining that status at 8 weeks was 62.20% with the single dose and 63.07% with multiple doses. Median overall survival was 12.4 weeks and 13.7 weeks, respectively, a nonsignificant difference.
Patients in the single-dose and multidose groups had similar rates of grade 3 or 4 toxicity (20.6% vs. 20.4%), but the former had a lower rate of grade 1 or 2 toxicity (51.0% vs. 56.9%).

Severe health conditions decline in childhood cancer survivors
CHICAGO – Severe health problems occurring 5 or more years after diagnosis of a childhood cancer have steadily declined, based on an analysis of 23,600 participants in the Childhood Cancer Survivor Study, funded by the National Institutes of Health.
For all childhood cancer survivors, the 15-year cumulative incidence of severe health conditions decreased from 12.7% in those diagnosed in the 1970s, to 10.1% in the 1980s, and to 8.8% among those diagnosed in the 1990s (per 10 years: hazard ratio, 0.84 [95% confidence interval, 0.80-0.89]), Todd M. Gibson, PhD, of St. Jude Children’s Research Hospital, Memphis, reported at a press conference at the annual meeting of the American Society of Clinical Oncology.
The association with diagnosis decade was attenuated (HR, 0.92 [95% CI, 0.85-1.00]) when detailed treatment data were included in the model, indicating that treatment reductions mediated risk.
Changes in childhood cancer treatment protocols to reduce the intensity of therapy – along with improved screening and early detection – have not only extended lifespan for many survivors, but also have reduced the incidence of serious chronic morbidity, Dr. Gibson said.
As the data address children diagnosed over 15 years ago, it is likely that improvements since then in determining patient risk and targeting therapy might result in further incremental improvements, he said in an interview.
By cancer type, severe health problems by 15 years after diagnosis decreased from 13% to 5% among survivors of Wilms’ tumor, from 18% to 11% among survivors of Hodgkin lymphoma, from 15% to 9% among survivors of astrocytoma, from 10% to 6% among survivors of non-Hodgkin lymphoma, and from 9% to 7% among survivors of acute lymphoblastic leukemia. The conclusions are based on the incidence of severe, disabling/life-threatening, or fatal chronic health conditions (Common Terminology Criteria for Adverse Events, grades 3-5) among 5-year survivors diagnosed prior to age 21 years from 1970 through 1999.
Adjusted for sex and attained age, significant reduction in risk over time was found among survivors of Wilms tumor (HR, 0.57 [95% CI, 0.46-0.70]), Hodgkin lymphoma (HR, 0.75 [95% CI, 0.65-0.85]), astrocytoma (HR, 0.77 [95% CI, 0.64-0.92]), non-Hodgkin lymphoma (HR, 0.79 [95% CI, 0.63-0.99]), and acute lymphoblastic leukemia (HR, 0.86 [95% CI, 0.76-0.98]).
The decreases in serious health conditions were largely driven by a reduced incidence of endocrine conditions (1970s: 4.0% vs. 1990s: 1.6%; HR, 0.66 [95% CI, 0.59-0.73]) and subsequent malignant neoplasms (1970s: 2.4% vs. 1990s: 1.6%; HR, 0.85 [95% CI, 0.76-0.96]).
Gastrointestinal (HR, 0.80 [95% CI, 0.66-0.97]) and neurological conditions (HR, 0.77 [95% CI, 0.65-0.91]) also were reduced, but cardiac and pulmonary conditions were not. Changes in childhood cancer treatment protocols have not only extended lifespan for many survivors, but also have reduced the incidence of serious chronic morbidity in this population, Dr. Gibson concluded.

The decreases in serious health conditions were largely driven by a reduced incidence of endocrine conditions (1970s: 4.0% vs. 1990s: 1.6%; HR, 0.66 [95% CI, 0.59-0.73]) and subsequent malignant neoplasms (1970s: 2.4% vs. 1990s: 1.6%; HR, 0.85 [95% CI, 0.76-0.96]).
Gastrointestinal (HR, 0.80 [95% CI, 0.66-0.97]) and neurological conditions (HR, 0.77 [95% CI, 0.65-0.91]) also were reduced, but cardiac and pulmonary conditions were not. Changes in childhood cancer treatment protocols have not only extended lifespan for many survivors, but also have reduced the incidence of serious chronic morbidity in this population, Dr. Gibson concluded.

VIDEO: Helping cancer patients cope with psychological side effects
CHICAGO – Oncologists are highly skilled at minimizing side effects associated with toxic but curative therapies, but are less adept at helping patients cope with the distress, anxiety, fear, and other emotions associated with cancer.
Three studies presented at the annual meeting of the American Society of Clinical Oncology detail randomized, controlled trials of psychological interventions aimed at helping patients cope with a new cancer diagnosis, reduce fears of a recurrence, and come to grips with the realities of advanced disease, including fears of death or disability.
Don S. Dizon, MD, from the Massachusetts General Hospital Cancer Center, Boston, discusses the social and financial barriers that cancer patients face when they experience distress, and the difficulties that providers face with limited time and financial resources to help patients cope in this video interview.

Oral HPV infections sharply lower for vaccinated youth
Vaccination against human papillomavirus (HPV) appears to be highly effective at preventing oral infection with oncogenic types of the virus, based on the results of a cohort study of a nationally representative sample of more than 2,600 U.S. young adults.
“HPV-positive oropharynx cancer is the fastest rising cancer among young white men in the United States. Over 90% of these cancers are caused by HPV type 16,” said senior study author Maura L. Gillison, MD, PhD, who conducted the research at Ohio State University, Columbus. “HPV 16 is one of the types covered in currently recommended HPV vaccines that have been shown to be safe and effective in the prevention of anogenital infections and associated cancers.
Results of the study showed that only about a sixth of the young adults surveyed between 2011 and 2014 had received at least one dose of an HPV vaccine. But relative to peers who had not received any doses, these young adults had an 88% lower prevalence of oral infection with HPV types 16, 18, 6, and 11, which are covered by vaccines; in particular, prevalence was 100% lower, with complete absence of these infections, in vaccinated young men, compared with unvaccinated young men, Dr. Gillison said in a presscast leading up to the annual meeting of the American Society of Clinical Oncology.
Analyses further suggested that based on levels of vaccine uptake seen in 2014 in the population, the vaccine was preventing only about 17% of the total of approximately 927,000 preventable oral infections with these virus types in that year.
“Our data indicate that HPV vaccines have tremendous potential to prevent oral infection,” said Dr. Gillison, noting that they are already strongly recommended by numerous health and medical organizations. Unfortunately, at the time of the study, “low vaccine uptake limited the population impact of the vaccine.”
However, there is now “considerable optimism,” she said, because recent data have shown that 60% of girls and 40% of boys younger than 18 have received at least one dose of HPV vaccine, marking a major increase in uptake.
“We can’t say that this is cause effect, the impact of these vaccines on infection, because this isn’t a prospective clinical trial,” she acknowledged. “Nevertheless, we can conclude that HPV vaccination may have additional benefits beyond prevention of anogenital cancers.”
The findings are encouraging in that they suggest it will be possible to avert infection-induced oropharyngeal cancer, according to ASCO President-Elect Bruce E. Johnson, MD, who is also chief clinical research officer at the Dana-Farber Cancer Institute and professor of medicine at Harvard Medical School, both in Boston.
“This certainly shows that in the target population to get vaccination, you can indeed prevent the infection, which is one of the first steps that would eventually potentially lead to cancer,” he said.
In the study, Dr. Gillison and her colleagues analyzed data from 2,627 men and women aged 18-33 years who participated in the National Health and Nutrition Examination Survey in the years 2011-2014. Oral rinses were collected as part of the survey to assess HPV infection.
The results showed that 18% of the young adults overall reported having received at least one dose of HPV vaccine, although receipt was much higher among young women than among young men (29% vs. 7%).
The prevalence of oral infection with HPV types 16/18/6/11 was sharply lower for these vaccinated young adults, compared with unvaccinated peers in the cohort as a whole (0.11% vs. 1.6%; P = .008). In a sex-stratified analysis, the reduction was especially striking among men (0% vs. 2%, P = .007), reported Dr. Gillison, who is now professor of thoracic/head and neck medical oncology at the University of Texas MD Anderson Cancer Center, Houston.
The vaccinated and unvaccinated groups did not differ significantly with respect to the combined prevalence of oral infection with 33 types of HPV that are not covered by vaccines.
When HPV vaccine uptake in the population in 2014 was considered, estimates suggested that vaccination was preventing only 17% of all vaccine-preventable oral HPV 16/18/6/11 infections in that year (25% in women and 7% in men).
Research on anogenital HPV infection, especially cervical HPV infection, suggests that most individuals will clear the infection on their own naturally, without any intervention, Dr. Gillison said. However, research has failed to identify good predictors of clearance or persistence.
“That’s why there is the current recommendation for universal vaccination of young boys and girls, because we don’t know how to distinguish someone who, like the overwhelming majority of individuals, is going to clear their infection with their own immune system, versus those who don’t have that capability and could progress to cancer,” she said.
Dr. Gillison disclosed that she has a consulting or advisory role with GlaxoSmithKline, Lilly, Bristol-Myers Squibb, AstraZeneca, Merck, and Celgene, and that she receives research funding (institutional) from Bristol-Myers Squibb, Kyowa Hakko Kirin, AstraZeneca, and Merck.

Healthy lifestyle, tree nuts may protect against colon cancer recurrence
Oncologists whose patients with treated early colon cancer ask what they can do to prevent it from coming back can now more strongly endorse lifestyle modification, based on findings from a pair of cohort studies reported at a presscast leading up to the annual meeting of the American Society of Clinical Oncology.
Both studies were conducted among more than 800 patients with stage III colon cancer participating in a nationwide randomized adjuvant chemotherapy trial who completed comprehensive lifestyle questionnaires.
Data for the studies were collected prospectively, noted ASCO President Daniel F. Hayes, MD. “So, that takes a lot of the biases out of the classic retrospective observational studies where patients are asked, ‘Do you remember what you did several years ago?’ Most of us would not. In this case, it was in real time, so it makes these findings even more compelling, in my opinion.
“We can now present optimism to patients with early-stage colon cancer,” Dr. Hayes added. “The odds of surviving colon cancer if it is not metastatic are quite high these days, thanks to lots of hard work and a number of trials done over the last 30 years showing that adequate surgery and adjuvant chemotherapy improve survival.”
Therefore, patients today have even more reason to make a commitment to a healthy lifestyle, which may further improve their outcomes, in addition to its other benefits, he commented.
At the same time, the studies’ findings should not be used to justify skipping good standard of care treatment for early colon cancer, stressed Dr. Hayes, who is also clinical director of the breast oncology program and Stuart B. Padnos Professor in breast cancer research at the University of Michigan in Ann Arbor.
“Nobody wants to undergo chemotherapy. We understand that,” Dr. Hayes said. “But chemotherapy clearly saves lives, so people should not interpret these two abstracts as suggesting that, if you live a healthy lifestyle and if you eat tree nuts, you don’t need to take the chemotherapy that your oncologist would recommend. That’s a very dangerous interpretation, and it’s not what we’re trying to get across. It’s that healthy people live healthier.”
In the first study, Erin Van Blarigan, ScD, assistant professor of epidemiology and biostatistics, University of California, San Francisco, and her colleagues assessed adherence to the American Cancer Society’s Nutrition and Physical Activity Guidelines for Cancer Survivors among 992 patients with stage III colon cancer who enrolled in the Cancer and Leukemia Group B (CALGB) 89803 adjuvant chemotherapy trial within 8 weeks of cancer resection.
“The guidelines are based on published scientific studies, but it’s not actually known if patients who follow the guidelines after diagnosis live longer,” she explained in the presscast.
All patients completed a validated lifestyle questionnaire during and 6 months after completing chemotherapy. Responses were used to assign patients points reflecting guideline adherence on body weight; regular physical activity; a dietary pattern high in vegetables, fruits, and whole grains, and low in red meat and processed meat; and alcohol intake (not specifically included in the guidelines but described in the text).
When lifestyle scores were calculated without consideration of alcohol intake, 26% of patients had a score of 0-1, corresponding to the least healthy lifestyle, while 9% had a score of 5-6, corresponding to the most healthy lifestyle, Dr. Van Blarigan reported.
Risks of both disease-free and overall survival events fell significantly with increasing score (P = .01). Compared with peers who scored 0-1, patients who scored 5-6 had a 42% lower risk of death.
When lifestyle scores were calculated with consideration of alcohol intake, 19% of patients had a score of 0-2, while 16% had a score of 6-8.
Here, too, risks of both disease-free and overall survival events fell significantly with increasing score (P = .002). Compared with peers who scored 0-2, patients who scored 6-8 had a 51% lower risk of death.
“Colon cancer patients who had a healthy body weight, engaged in regular physical activity of approximately 1 hour 5 days a week, and ate a diet rich in a variety of vegetables and fruit – choosing whole grains over refined ones, avoiding red and processed meats, and drinking small to moderate amounts of alcohol – had longer disease-free and overall survival, compared with patients who did not engage in these behaviors,” summarized Dr. Van Blarigan.
The mechanism by which low to moderate alcohol intake, compared with none, may be protective is unclear, but the pattern is consistent with that seen for other diseases, she said.
“There has been some literature in cardiovascular disease about changes in insulin and inflammation and elasticity of blood vessels and things like that,” Dr. Van Blarigan noted. “So, I think that’s something to explore further for colon cancer.”
In the second study, Temidayo Fadelu, MD, a clinical fellow in medicine at the Dana-Farber Cancer Institute in Boston, and his colleagues assessed nut intake among 826 patients enrolled in the same trial. They used questionnaires completed 6 months after the end of chemotherapy, which asked about consumption of tree nuts, peanuts, and peanut butter.
“States of energy excess are associated with an increased risk of colon cancer death and recurrence … and one mechanism is thought to maybe be hyperinsulinemia,” he commented in the presscast. Research has found nut consumption to be associated with lower incidences of type 2 diabetes, metabolic syndrome, and insulin resistance.
Study results showed that the adjusted risks of both disease-free survival and overall survival events fell with increasing frequency of total nut consumption. Patients eating nuts at least twice weekly (19% of the cohort) had a 42% lower adjusted risk of disease-free survival events and a 57% lower adjusted risk of death, relative to counterparts who never ate nuts.
“We don’t really know what the underlying biologic mechanism is for this association, but we hypothesize that it’s perhaps due to the influence of nuts on insulin resistance,” Dr. Fadelu said, noting that they contain fatty acids, fiber, and flavonoids and that insulin levels rise to a lesser degree after eating nuts than after eating foods such as simple sugars. “There need to be further studies to really evaluate this hypothesis,” he added.
“We did a secondary analysis, and we observed that the association described was limited to tree nuts; the association was not seen with peanuts or peanut butter intake,” noted Dr. Fadelu, who reported that he had no disclosures. “Peanuts are technically legumes, and this difference may perhaps be due to the different biochemical composition between peanuts and tree nuts.”
Dr. Van Blarigan reported that she had no disclosures. Dr. Fadelu reported that he had no disclosures.

In the first study, Erin Van Blarigan, ScD, assistant professor of epidemiology and biostatistics, University of California, San Francisco, and her colleagues assessed adherence to the American Cancer Society’s Nutrition and Physical Activity Guidelines for Cancer Survivors among 992 patients with stage III colon cancer who enrolled in the Cancer and Leukemia Group B (CALGB) 89803 adjuvant chemotherapy trial within 8 weeks of cancer resection.
“The guidelines are based on published scientific studies, but it’s not actually known if patients who follow the guidelines after diagnosis live longer,” she explained in the presscast.
All patients completed a validated lifestyle questionnaire during and 6 months after completing chemotherapy. Responses were used to assign patients points reflecting guideline adherence on body weight; regular physical activity; a dietary pattern high in vegetables, fruits, and whole grains, and low in red meat and processed meat; and alcohol intake (not specifically included in the guidelines but described in the text).
When lifestyle scores were calculated without consideration of alcohol intake, 26% of patients had a score of 0-1, corresponding to the least healthy lifestyle, while 9% had a score of 5-6, corresponding to the most healthy lifestyle, Dr. Van Blarigan reported.
Risks of both disease-free and overall survival events fell significantly with increasing score (P = .01). Compared with peers who scored 0-1, patients who scored 5-6 had a 42% lower risk of death.
When lifestyle scores were calculated with consideration of alcohol intake, 19% of patients had a score of 0-2, while 16% had a score of 6-8.
Here, too, risks of both disease-free and overall survival events fell significantly with increasing score (P = .002). Compared with peers who scored 0-2, patients who scored 6-8 had a 51% lower risk of death.
“Colon cancer patients who had a healthy body weight, engaged in regular physical activity of approximately 1 hour 5 days a week, and ate a diet rich in a variety of vegetables and fruit – choosing whole grains over refined ones, avoiding red and processed meats, and drinking small to moderate amounts of alcohol – had longer disease-free and overall survival, compared with patients who did not engage in these behaviors,” summarized Dr. Van Blarigan.
The mechanism by which low to moderate alcohol intake, compared with none, may be protective is unclear, but the pattern is consistent with that seen for other diseases, she said.
“There has been some literature in cardiovascular disease about changes in insulin and inflammation and elasticity of blood vessels and things like that,” Dr. Van Blarigan noted. “So, I think that’s something to explore further for colon cancer.”
In the second study, Temidayo Fadelu, MD, a clinical fellow in medicine at the Dana-Farber Cancer Institute in Boston, and his colleagues assessed nut intake among 826 patients enrolled in the same trial. They used questionnaires completed 6 months after the end of chemotherapy, which asked about consumption of tree nuts, peanuts, and peanut butter.
“States of energy excess are associated with an increased risk of colon cancer death and recurrence … and one mechanism is thought to maybe be hyperinsulinemia,” he commented in the presscast. Research has found nut consumption to be associated with lower incidences of type 2 diabetes, metabolic syndrome, and insulin resistance.
Study results showed that the adjusted risks of both disease-free survival and overall survival events fell with increasing frequency of total nut consumption. Patients eating nuts at least twice weekly (19% of the cohort) had a 42% lower adjusted risk of disease-free survival events and a 57% lower adjusted risk of death, relative to counterparts who never ate nuts.
“We don’t really know what the underlying biologic mechanism is for this association, but we hypothesize that it’s perhaps due to the influence of nuts on insulin resistance,” Dr. Fadelu said, noting that they contain fatty acids, fiber, and flavonoids and that insulin levels rise to a lesser degree after eating nuts than after eating foods such as simple sugars. “There need to be further studies to really evaluate this hypothesis,” he added.
“We did a secondary analysis, and we observed that the association described was limited to tree nuts; the association was not seen with peanuts or peanut butter intake,” noted Dr. Fadelu, who reported that he had no disclosures. “Peanuts are technically legumes, and this difference may perhaps be due to the different biochemical composition between peanuts and tree nuts.”
Dr. Van Blarigan reported that she had no disclosures. Dr. Fadelu reported that he had no disclosures.
Oncologists whose patients with treated early colon cancer ask what they can do to prevent it from coming back can now more strongly endorse lifestyle modification, based on findings from a pair of cohort studies reported at a presscast leading up to the annual meeting of the American Society of Clinical Oncology.
Both studies were conducted among more than 800 patients with stage III colon cancer participating in a nationwide randomized adjuvant chemotherapy trial who completed comprehensive lifestyle questionnaires.
Data for the studies were collected prospectively, noted ASCO President Daniel F. Hayes, MD. “So, that takes a lot of the biases out of the classic retrospective observational studies where patients are asked, ‘Do you remember what you did several years ago?’ Most of us would not. In this case, it was in real time, so it makes these findings even more compelling, in my opinion.
“We can now present optimism to patients with early-stage colon cancer,” Dr. Hayes added. “The odds of surviving colon cancer if it is not metastatic are quite high these days, thanks to lots of hard work and a number of trials done over the last 30 years showing that adequate surgery and adjuvant chemotherapy improve survival.”
Therefore, patients today have even more reason to make a commitment to a healthy lifestyle, which may further improve their outcomes, in addition to its other benefits, he commented.
At the same time, the studies’ findings should not be used to justify skipping good standard of care treatment for early colon cancer, stressed Dr. Hayes, who is also clinical director of the breast oncology program and Stuart B. Padnos Professor in breast cancer research at the University of Michigan in Ann Arbor.
“Nobody wants to undergo chemotherapy. We understand that,” Dr. Hayes said. “But chemotherapy clearly saves lives, so people should not interpret these two abstracts as suggesting that, if you live a healthy lifestyle and if you eat tree nuts, you don’t need to take the chemotherapy that your oncologist would recommend. That’s a very dangerous interpretation, and it’s not what we’re trying to get across. It’s that healthy people live healthier.”

Early allo SCT advised for high-risk mantle cell lymphoma
High-risk patients with mantle cell lymphoma who have a matched related donor have a better chance for survival if they don’t delay allogeneic hematopoietic stem cell transplantation (allo SCT), based on a small single-center study reported by Daniel Allen Kobrinski, DO, and his colleagues at Loyola University, Chicago.
They based the recommendation on the outcomes of 29 mantle cell lymphoma patients who underwent allo SCT at Loyola University Medical Center between Jan. 1, 1999 and Jan. 1, 2016. Before having allo SCT, 23 of 29 patients had three or more lines of treatment. Six had myeloablative conditioning and 23 had reduced-intensity conditioning; 15 had a related donor, 6 had a matched unrelated donor, and 8 had an unmatched cord blood donor.
Probability estimates for overall survival and non–relapse mortality at 5 years were calculated from the date of allo SCT to the date of patient death or last known follow-up. The 5-year rate of overall survival was 42% and the rate of non–relapse mortality was 53%. Based on a univariate analysis, the risk of death was lower in patients who received total body irradiation-based conditioning (hazard ratio, 0.19; 95% confidence interval, 0.04-0.81; P = .03), and in those who had HLA-matched, related donor transplants (HR, 0.29; 95% CI, 0.11-0.79; P = .02).
Patients who received more than three lines of prior treatment had a higher risk of death (HR, 2.77; 95% CI, 1.05-7.34; P = .04).
Four of the patients had grade III/IV acute graft-versus-host disease (GVHD) and four relapsed. Two patients died from acute GVHD, and most of the other deaths were from treatment-related toxicities.
Dr. Kobrinski had no relationships to disclose.
