Hodgkin Lymphoma

Starting breast cancer screening in young adulthood has the potential to sharply reduce deaths from the disease among women who have received chest radiation for childhood cancer, a modeling study suggests.

Two strategies – annual mammography with MRI and annual MRI alone – at least halved breast cancer mortality when started at the ages of 25 or 30 years.

Jennifer M. Yeh, PhD, of Harvard Medical School in Boston and colleagues reported these results in the Annals of Internal Medicine.

When cost was also considered, 30 years emerged as the preferred starting age, dropping the incremental cost-effectiveness ratio (ICER) below the generally accepted threshold of $100,000 per quality-adjusted life-year gained.

“Our findings underscore the importance of making sure that young women previously treated with chest radiation are informed about their elevated breast cancer risk and the benefits of routine screening. Both primary care providers and oncologists who care for survivors should discuss breast cancer screening with these patients,” Dr. Yeh and colleagues wrote.

“Screening guidelines should emphasize the importance of MRI screening (with or without mammography) among survivors,” the authors recommended. “Our findings also highlight the importance of ensuring that survivors have access to health insurance coverage for MRI screening.”
 

Implications for awareness, coverage

“My hope is that, by showing the significantly decreased risk of death associated with early breast cancer screening, with harm-benefit ratios considerably lower than benchmarks for average-risk women, this study will help health insurance companies see the benefit in covering early screening for at-risk survivors,” commented Karen E. Effinger, MD, of Emory University, Atlanta, and the Aflac Cancer & Blood Disorders Center at Children’s Healthcare of Atlanta.

“In many survivors, the cost of current screening [as recommended by] guidelines is prohibitive,” added Dr. Effinger, who was not involved in the current study.

The main concern regarding the study’s findings is generalizability to the contemporary era, given the use of a cohort diagnosed and treated decades ago and changes in radiation techniques and dosing since then, she noted in an interview. This limitation was addressed in a sensitivity analysis that halved the women’s base-case lifetime risk of breast cancer and still netted similar results.

“However, it will take many years to determine the true risk reduction of our current treatment strategies,” Dr. Effinger acknowledged.

“It is crucial that we improve our education of both survivors and our colleagues who care for these survivors, especially in regard to risk of subsequent malignancies and the benefits of screening,” Dr. Effinger maintained. “While many people are aware of the risk of breast cancer associated with BRCA mutations, the increased risk in survivors of childhood cancer is not as recognized by nononcologists. This study reinforces that increasing this awareness can save lives.”

In educating their patients about preventive care, health care providers must strike “a fine balance between discussing the risks and benefits of screening without provoking significant anxiety,” she concluded. “It is important for survivors to establish care with a primary care provider in order to develop trust and receive the guidance they need to decrease the risk of early mortality.”
 

Study details

Dr. Yeh and colleagues developed models to compare outcomes with various screening strategies among women aged 20 years who had received chest radiotherapy for childhood cancer during 1970-1986. The women had been diagnosed with Hodgkin lymphoma (55%), Wilms tumor (12%), non-Hodgkin lymphoma (8%), and other cancers.

The investigators conducted their analysis using data from the Childhood Cancer Survivor Study and other published sources, a lifetime time horizon, and a payer perspective.

The team assessed three strategies: no screening; digital mammography with MRI screening starting at 25 years of age (the current Children’s Oncology Group recommendation), 30 years, or 35 years and continuing to 74 years of age; and MRI only starting at age 25, 30, or 35 years and continuing to age 74 years.

The main study results showed that, without screening, women who had received chest radiation for childhood cancer had a 10%-11% lifetime risk of breast cancer mortality across models.

Relative to no screening, starting at age 25 years, the largest share of deaths was averted with the strategy of annual mammography with MRI – 56.3%-71.2% – or with the strategy of annual MRI alone – 55.7%-62.0%.

These two strategies also yielded the most screening tests, as well as the most false-positive test results and benign biopsy results.

For women who started screening at age 25, there were 4,188-4,879 false-positive test results per 1,000 women for mammography plus MRI and 3,283-3,764 false-positive results per 1,000 women for MRI alone.

For women who started screening at age 25, there were 1,340-1,561 benign biopsy results per 1,000 women for mammography plus MRI and 1,248-1,430 benign results per 1,000 women for MRI alone.

After cost was factored in, beginning screening at age 30 emerged as the preferred strategy to achieve an ICER threshold of less than $100,000 per quality-adjusted life-year gained.

When started at 30 years of age, annual mammography with MRI averted 54.7%-68.8% of breast cancer deaths, with an ICER of $25,400-$113,200 per quality-adjusted life-year gained. Annual MRI alone averted 54.0%-60.0% of breast cancer deaths, with an ICER of $21,800-$50,580 per quality-adjusted life-year gained.

This research was supported by grants from the National Cancer Institute, American Cancer Society, and American Lebanese Syrian Associated Charities. The authors disclosed relationships with GE Healthcare and Biovector. Dr. Effinger disclosed no relevant conflicts of interest.

Atopic eczema was linked with a significantly increased risk of lymphoma, and severe eczema was associated with a twofold increase in non-Hodgkin lymphoma (NHL) risk, according to two matched longitudinal cohort studies from England and Denmark.

“In this study, no evidence was found that people with atopic eczema are at increased risk of most cancers. An exception is the observed association between atopic eczema and lymphoma, particularly NHL, [which] increased with eczema severity,” Kathryn E. Mansfield, PhD, wrote in JAMA Dermatology. Adjusted hazard ratios for NHL in the English cohort were 1.06 (99% CI, 0.90-1.25) for mild atopic eczema, 1.24 (99% CI, 1.04-1.48) for moderate eczema, and 2.08 (99% CI, 1.42-3.04) for severe eczema, reported Dr. Mansfield of the London School of Hygiene and Tropical Medicine and associates.

Past studies of a possible link between atopic eczema and cancer have produced conflicting evidence, which might reflect “two competing theories” – that cancer risk falls with greater immune surveillance, and that cancer risk rises with immune stimulation, the researchers wrote. Immunosuppressive treatment and an impaired skin barrier might also increase the risk of cancer, but the evidence is conflicting.

For the study, they analyzed electronic health records linked with hospital admissions and death records in England and national health registry data from Denmark. The English cohort included 471,970 adults with atopic eczema and 2,239,775 adults without atopic eczema. The Danish cohort was composed of individuals of any age, including 44,945 who had eczema and with 445,673 who did not. Participants were matched based on factors such as age, sex, and primary care practice. The researchers excluded individuals with a history of cancer, apart from nonmelanoma skin cancer or keratinocyte cancer. (For analyses of skin cancer risk, they also excluded individuals with a history of nonmelanoma skin cancer.)

Overall, there was “little evidence” for a link between atopic eczema and cancer (adjusted hazard ratio in England, 1.04; 99% CI, 1.02-1.06; aHR in Denmark, 1.05; 99% CI, 0.95-1.16) or for most specific types of cancer, the investigators wrote.

In England, however, eczema was associated with a significantly increased risk for noncutaneous lymphoma, with an adjusted HRs of 1.19 (99% CI, 1.07-1.34) for NHL, and 1.48 (99% CI, 1.07-2.04) for Hodgkin lymphoma. Lymphoma risk was highest among adults with severe eczema, defined as those who had been prescribed a systemic treatment for their disease, who had received phototherapy, or who had been referred to a specialist or admitted to a hospital for atopic eczema. Point estimates in the Danish cohort also revealed a higher risk for lymphoma among individuals with moderate to severe atopic eczema, compared with those with eczema, but the 99% CIs crossed 1.0.

The findings highlight the need to be aware of, screen for, and study the pathogenesis of heightened lymphoma risk among patients with atopic eczema, said Shawn Demehri, MD, PhD, of the department of dermatology and cancer center, at Massachusetts General Hospital, Boston, who was not involved in the study.

“Prospectively collected data from large cohorts of eczema patients is a strength of this study,” he said in an interview. “However, the age range included in the study is suboptimal for assessing cancer as an outcome. The lower incidence of cancer in younger individuals hinders the ability to detect differences in cancer risk between the two groups.” (Approximately 57% of individuals in the English cohort were aged 18-44 years, while approximately 70% of those in the Danish cohort were less than 18 years.)

Understanding how eczema affects the risk of non-Hodgkin lymphoma is an important future direction of research, Dr. Demehri emphasized. “The landscape of atopic eczema therapeutics has dramatically changed in the recent years. It will be very interesting to determine how new biologics impact cancer risk in eczema patients.”

Partial support for the work was provided by the Wellcome Trust, the Royal Society, the Dagmar Marshalls Fund, and the Aase and Ejnar Danielsens Fund. Dr. Mansfield disclosed support from a Wellcome Trust grant. Her coinvestigators disclosed ties to TARGET-DERM, Pfizer, and GlaxoSmithKline, and from the Wellcome Trust, Medical Research Council, the National Institute for Health Research, the British Heart Foundation, Diabetes UK, and IMI Horizon 2020 funding BIOMAP. Dr. Demehri reported having no relevant conflicts of interest.

The majority of patients with early-stage unfavorable Hodgkin lymphoma respond well enough to a current standard regimen of four cycles of chemotherapy and can skip the additional radiotherapy that is normally included in the combined modality treatment, say experts reporting the final results from an international phase 3 randomized trial dubbed HD17.

“Most patients with this disease will not need radiotherapy any longer,” concluded first author Peter Borchmann, MD, assistant medical director in the department of hematology/oncology at the University Hospital Cologne (Germany).

Dr. Borchmann was speaking online as part of the virtual edition of the European Hematology Association 25th Annual Congress 2020.

“Importantly, the mortality of patients with early-stage unfavorable Hodgkin lymphoma in the HD17 study did not differ from the normal healthy German population, and this is the first time we have had this finding in one of our studies,” he emphasized.

Dr. Borchmann added that positron emission tomography imaging is key in deciding which patients can skip radiation.

“We conclude from the HD17 trial that the combined modality concept can and should be replaced by a PET-guided omission of radiotherapy for patients with newly diagnosed early-stage unfavorable Hodgkin lymphoma,” he said.

“The vast majority of early-stage unfavorable Hodgkin lymphoma patients can be treated with the brief and highly effective 2+2 chemotherapy alone,” he added.

Therefore, he continued, “PET-guided 2+2 chemotherapy is the new standard of care for the German Hodgkin study group,” which conducted the trial.

The use of both chemotherapy and radiation has long been a standard approach to treatment, and this combined modality treatment is highly effective, Dr. Borchmann explained. But it can cause long-term damage, and the known longer-term negative effects of radiotherapy, such as cardiovascular disease and second malignancies, are a particular concern because patients with early-stage Hodgkin lymphoma are relatively young, with a median age of around 30 years at disease onset.

An expert approached for comment said that the momentum to skip radiotherapy when possible is an ongoing issue, and importantly, this study adds to those efforts.

“The treatment of Hodgkin lymphoma has moved for many years now to less radiation therapy, and this trend will continue with the results of this study,” commented John G. Gribben, MD, director of the Stem Cell Transplantation Program and medical director of the North East London Cancer Research Network Centre at Barts Cancer Center of Excellence and the London School of Medicine.

“We have moved to lower doses and involved fields with the intent of decreasing toxicity, and particularly long-term toxicity from radiotherapy,” he said in an interview.

For the multicenter, phase 3 HD17 trial, Dr. Borchmann and colleagues turned to PET to identify patients who had and had not responded well to chemotherapy (PET negative and PET positive) and to determine if those who had responded well could safely avoid radiotherapy without compromising efficacy.

“We wanted to determine if we could reduce the treatment intensity by omission of radiotherapy in patients who respond very well to the systemic treatment, so who have a complete metabolic remission after the chemotherapy,” Dr. Borchmann said.

The 2+2 treatment approach includes two cycles of eBEACOPP (bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone) and two subsequent cycles of ABVD (doxorubicin, bleomycin, vinblastine, and dacarbazine).

The trial enrolled 1,100 patients with newly diagnosed Hodgkin lymphoma between January 2012 and March 2017. Of these, 979 patients had confirmed PET results, with 651 (66.5%) found to be PET negative, defined as having a Deauville score (DS) of less than 3 (DS3); 238 (24.3%) were DS3, and 90 (9.2%) were DS4.

The study met its primary endpoint of noninferiority in progression-free survival (PFS) at 5 years, with a PFS of 95.1% in the PET-guided group (n = 447), compared with 97.3% in the standard combined-modality treatment group (n = 428), over a median observation time of 45 months, for a difference of 2.2% (P = .12).

“We found that the survival levels were very high, and we can safely conclude the noninferiority of the PET-guided approach in PET-negative patients,” Dr. Borchmann said.

A further analysis showed that the 597 PET-negative patients who did not receive radiotherapy because of their PET status had 5-year PFS that was noninferior to the combined modality group (95.9% vs. 97.7%, respectively; P = .20).

And among 646 patients who received the 2+2 regimen plus radiotherapy, of those confirmed as PET positive (n = 328), the estimated 5-year PFS was significantly lower (94.2%), compared with those determined to be PET negative (n = 318; 97.6%; hazard ratio, 3.03).

A cut-off of DS4 for positivity was associated with a stronger effect, with a lower estimated 5-year PFS of 81.6% vs. 98.8% for DS3 patients and 97.6% for DS less than 3 (P < .0001).

“Only DS4 has a prognostic impact, but not DS3,” Dr. Borchmann said. “DS4 positivity indicates a relevant risk for treatment failure, however, there are few patients in this risk group (9.2% in this trial).”

The 5-year overall survival rates in an intent-to-treat analysis were 98.8% in the standard combined modality group and 98.4% in the PET-guided group.

With a median observation time of 47 months, there have been 10 fatal events in the trial out of 1,100 patients, including two Hodgkin lymphoma-related events and one treatment-related death.

“Overall, Hodgkin lymphoma or treatment-related mortality rates were extremely low,” Dr. Borchmann said.

The study was funded by Deutsche Krebshilfe. Dr. Borchmann and Dr. Gribben have reported no relevant financial relationships.

The majority of patients with early-stage unfavorable Hodgkin lymphoma respond well enough to a current standard regimen of four cycles of chemotherapy and can skip the additional radiotherapy that is normally included in the combined modality treatment, say experts reporting the final results from an international phase 3 randomized trial dubbed HD17.

“Most patients with this disease will not need radiotherapy any longer,” concluded first author Peter Borchmann, MD, assistant medical director in the department of hematology/oncology at the University Hospital Cologne (Germany).

Dr. Borchmann was speaking online as part of the virtual edition of the European Hematology Association 25th Annual Congress 2020.

“Importantly, the mortality of patients with early-stage unfavorable Hodgkin lymphoma in the HD17 study did not differ from the normal healthy German population, and this is the first time we have had this finding in one of our studies,” he emphasized.

Dr. Borchmann added that positron emission tomography imaging is key in deciding which patients can skip radiation.

“We conclude from the HD17 trial that the combined modality concept can and should be replaced by a PET-guided omission of radiotherapy for patients with newly diagnosed early-stage unfavorable Hodgkin lymphoma,” he said.

“The vast majority of early-stage unfavorable Hodgkin lymphoma patients can be treated with the brief and highly effective 2+2 chemotherapy alone,” he added.

Therefore, he continued, “PET-guided 2+2 chemotherapy is the new standard of care for the German Hodgkin study group,” which conducted the trial.

The use of both chemotherapy and radiation has long been a standard approach to treatment, and this combined modality treatment is highly effective, Dr. Borchmann explained. But it can cause long-term damage, and the known longer-term negative effects of radiotherapy, such as cardiovascular disease and second malignancies, are a particular concern because patients with early-stage Hodgkin lymphoma are relatively young, with a median age of around 30 years at disease onset.

An expert approached for comment said that the momentum to skip radiotherapy when possible is an ongoing issue, and importantly, this study adds to those efforts.

“The treatment of Hodgkin lymphoma has moved for many years now to less radiation therapy, and this trend will continue with the results of this study,” commented John G. Gribben, MD, director of the Stem Cell Transplantation Program and medical director of the North East London Cancer Research Network Centre at Barts Cancer Center of Excellence and the London School of Medicine.

“We have moved to lower doses and involved fields with the intent of decreasing toxicity, and particularly long-term toxicity from radiotherapy,” he said in an interview.

Hidradenitis suppurativa (HS) was associated with a significantly increased risk of any cancer as well as for several specific cancers in a population-based study of approximately 200,000 individuals in Korea.

HS is associated with severe comorbidities, and previous studies have suggested a link between HS and cancer development, wrote Joon Min Jung, MD, of the University of Ulsan College of Medicine, Seoul, Korea, and colleagues.

“The aberrant immune response and chronic inflammation in HS and genetic and environmental factors associated with the disease may all be factors in the development of cancer,” but large, population-based studies of cancer in HS patients are limited, they noted.

In a study published in JAMA Dermatology, the researchers reviewed data from 22,468 adults with HS and 179,734 matched controls, in the Korean National Health Insurance System, seen by physicians between January 2009 and December 2017. The average age of the participants was 34 years, and 64% were male.

Overall, HS patients had a significantly higher risk of cancer compared with controls, with an adjusted hazard ratio (aHR) of 1.28.

As for specific cancers, HS patients had a significantly higher risk for Hodgkin lymphoma (aHR 5.08), oral cavity and pharyngeal cancer (aHR 3.10), central nervous system cancer (aHR 2.40), nonmelanoma skin cancer (aHR 2.06), prostate cancer (aHR 2.05), and colorectal cancer (aHR 1.45).

The risk of any cancer was not significantly different between women with HS and female controls (after adjustment for comorbidities), but was significantly higher among men with HS compared with male controls, also after adjustment for comorbidities (aHR, 1.37). In addition, HS patients in both younger (less than 40 years) and older (aged 40 years and older) age groups had increased cancer risk compared with age-matched controls. Overall cancer risk and the risk of most cancer types were higher among HS patients with moderate to severe disease than in those with mild disease, with the exception of nonmelanoma skin cancer, prostate cancer, lymphoma, and leukemia.

“Overall cancer risk showed a tendency to increase with worsening HS severity, reinforcing the possibility of an association between HS and cancer development,” the researchers noted. “However, we could not identify tendencies in some specific cancers, such as nonmelanoma skin cancer, CNS cancer, and prostate cancer, because the number of occurrences of those cancers was too small in the group with moderate to severe HS.”

The study findings were limited by several factors including the potential underestimate of HS cases in the population and the inability of the study design to adjust for factors including smoking status, alcohol use, and obesity, the researchers noted. However, the results support an increased cancer risk in HS patients and suggest the need to promote lifestyle modifications to reduce risk, and to increase cancer surveillance in these patients, they said. “For early detection of skin cancer, more aggressive histologic examination and a high level of suspicion are required,” they added.

The study was supported by the National Research Foundation of Korea and the Korea Health Technology R&D Project. The researchers had no financial conflicts to disclose.

Pembrolizumab treatment significantly improved progression-free survival versus brentuximab vedotin in a randomized, phase 3 trial including patients with relapsed or refractory classical Hodgkin lymphoma, an investigator has reported.

Median progression-free survival (PFS) was 13.2 versus 8.3 months in favor of pembrolizumab, according to the report on the KEYNOTE-204 trial, which included patients with classical Hodgkin lymphoma who either had relapsed after autologous stem cell transplant (SCT) or were ineligible for autologous SCT.

The PFS improvement was “statistically significant and clinically meaningful,” said investigator John Kuruvilla, MD, of Princess Margaret Cancer Centre in Toronto.

“This PFS benefit extended to key subgroups, including those ineligible for autologous transplant, patients with primary refractory disease, and patients who were brentuximab-vedotin naive,” Dr. Kuruvilla added in his presentation, which was part of the American Society of Clinical Oncology virtual scientific program.

Pneumonitis was more frequent in the pembrolizumab arm, but “appeared in general to be quite well managed” among patients who experienced this adverse event, according to Dr. Kuruvilla, who said that treatment with the programmed death–1 inhibitor should be considered “the preferred treatment option and the new standard of care” for patients with relapsed/refractory classic Hodgkin lymphoma who have relapsed after autologous SCT or are ineligible for it.

Although the pneumonitis findings are important to keep in mind, results of KEYNOTE-204 are indeed “practice defining” and immediately impactful, said Mark J. Roschewski, MD, clinical investigator in the lymphoid malignancies branch at the Center for Cancer Research, part of the National Cancer Institute, Bethesda, Md.

“I would select pembrolizumab over brentuximab for this patient population, particularly those that are refractory to chemotherapy,” he said in a commentary on the study also included in the virtual ASCO proceedings.

“There may be specific patient populations that I’d reconsider, such as those that might be at high risk for lung toxicity,” he added. “They may not be suitable for this, but it’s something to at least to be aware of.”

Although the antibody-drug conjugate brentuximab vedotin has been considered the standard of care for patients with relapse after autologous SCT, there has historically been no standard of care for patients who are ineligible for transplant because of chemorefractory disease, advanced age, or comorbidities, Dr. Kuruvilla said in his presentation.

In the KEYNOTE-204 study, 304 patients with relapsed/refractory classic Hodgkin lymphoma were randomized to receive either pembrolizumab 200 mg or brentuximab at 1.8 mg/kg intravenously every 3 weeks for up to 35 cycles.

The median age of patients was 36 years in the pembrolizumab arm and 35 years in the brentuximab vedotin arm, according to the report. Approximately 37% of the patients had previously undergone autologous SCT. About 40% had been refractory to frontline therapy, while 28% relapsed within 12 months of therapy and 32% relapsed later than 12 months.

Median PFS by blinded independent central review was 13.2 versus 8.3 months in the pembrolizumab and brentuximab arms, respectively (hazard ratio, 0.65; 95% confidence interval, 0.48-0.88; P = .00271), Dr. Kuruvilla reported.

The benefit extended to “key subgroups” in the trial, he added, including those who were ineligible for autologous SCT, those with primary refractory disease, and those who were naive to brentuximab vedotin, with HRs of 0.61, 0.52, and 0.67, respectively.

Pembrolizumab was also associated with more durable responses versus brentuximab vedotin, according to the investigator.

The overall response rate was 65.6% and 54.2%, respectively, for pembrolizumab and brentuximab, although this difference of approximately 11 percentage points did not meet criteria for statistical significance, he said. Duration of response was 20.7 months or pembrolizumab and 13.8 months for brentuximab.

The rate of serious treatment-related adverse events was similar between groups, according to Dr. Kuruvilla, who reported grade 3-5 events occurring in 19.6% and 25.0% of the pembrolizumab and brentuximab arms. Serious treatment-related adverse events were numerically more frequent in the pembrolizumab arm (16.2% vs. 10.5%) and there was one treatment-related death caused by pneumonia, seen in the pembrolizumab arm.

Pneumonitis occurred in 2.6% of the brentuximab-treated patients and in 10.8% of pembrolizumab-treated patients, of which half of cases were grade 3-4, according to the report.

In the pembrolizumab arm, pneumonitis was felt to be drug-related in 15 of 16 cases, according to Dr. Kuruvilla, who added that 15 of 16 patients required corticosteroid therapy. “This has led to the resolution of the pneumonitis in 12 of 16 patients, with ongoing resolution in one further patient.”

Research funding for KEYNOTE-204 came from Merck Sharp & Dohme. Dr. Kuruvilla provided disclosures related to Merck and a variety of other pharmaceutical companies. Dr. Roschewski said he had no relationships to disclose.

Median PFS by blinded independent central review was 13.2 versus 8.3 months in the pembrolizumab and brentuximab arms, respectively (hazard ratio, 0.65; 95% confidence interval, 0.48-0.88; P = .00271), Dr. Kuruvilla reported.

The benefit extended to “key subgroups” in the trial, he added, including those who were ineligible for autologous SCT, those with primary refractory disease, and those who were naive to brentuximab vedotin, with HRs of 0.61, 0.52, and 0.67, respectively.

Pembrolizumab was also associated with more durable responses versus brentuximab vedotin, according to the investigator.

The overall response rate was 65.6% and 54.2%, respectively, for pembrolizumab and brentuximab, although this difference of approximately 11 percentage points did not meet criteria for statistical significance, he said. Duration of response was 20.7 months or pembrolizumab and 13.8 months for brentuximab.

The rate of serious treatment-related adverse events was similar between groups, according to Dr. Kuruvilla, who reported grade 3-5 events occurring in 19.6% and 25.0% of the pembrolizumab and brentuximab arms. Serious treatment-related adverse events were numerically more frequent in the pembrolizumab arm (16.2% vs. 10.5%) and there was one treatment-related death caused by pneumonia, seen in the pembrolizumab arm.

Pneumonitis occurred in 2.6% of the brentuximab-treated patients and in 10.8% of pembrolizumab-treated patients, of which half of cases were grade 3-4, according to the report.

In the pembrolizumab arm, pneumonitis was felt to be drug-related in 15 of 16 cases, according to Dr. Kuruvilla, who added that 15 of 16 patients required corticosteroid therapy. “This has led to the resolution of the pneumonitis in 12 of 16 patients, with ongoing resolution in one further patient.”

Research funding for KEYNOTE-204 came from Merck Sharp & Dohme. Dr. Kuruvilla provided disclosures related to Merck and a variety of other pharmaceutical companies. Dr. Roschewski said he had no relationships to disclose.

Pembrolizumab treatment significantly improved progression-free survival versus brentuximab vedotin in a randomized, phase 3 trial including patients with relapsed or refractory classical Hodgkin lymphoma, an investigator has reported.

Median progression-free survival (PFS) was 13.2 versus 8.3 months in favor of pembrolizumab, according to the report on the KEYNOTE-204 trial, which included patients with classical Hodgkin lymphoma who either had relapsed after autologous stem cell transplant (SCT) or were ineligible for autologous SCT.

The PFS improvement was “statistically significant and clinically meaningful,” said investigator John Kuruvilla, MD, of Princess Margaret Cancer Centre in Toronto.

“This PFS benefit extended to key subgroups, including those ineligible for autologous transplant, patients with primary refractory disease, and patients who were brentuximab-vedotin naive,” Dr. Kuruvilla added in his presentation, which was part of the American Society of Clinical Oncology virtual scientific program.

Pneumonitis was more frequent in the pembrolizumab arm, but “appeared in general to be quite well managed” among patients who experienced this adverse event, according to Dr. Kuruvilla, who said that treatment with the programmed death–1 inhibitor should be considered “the preferred treatment option and the new standard of care” for patients with relapsed/refractory classic Hodgkin lymphoma who have relapsed after autologous SCT or are ineligible for it.

Although the pneumonitis findings are important to keep in mind, results of KEYNOTE-204 are indeed “practice defining” and immediately impactful, said Mark J. Roschewski, MD, clinical investigator in the lymphoid malignancies branch at the Center for Cancer Research, part of the National Cancer Institute, Bethesda, Md.

“I would select pembrolizumab over brentuximab for this patient population, particularly those that are refractory to chemotherapy,” he said in a commentary on the study also included in the virtual ASCO proceedings.

“There may be specific patient populations that I’d reconsider, such as those that might be at high risk for lung toxicity,” he added. “They may not be suitable for this, but it’s something to at least to be aware of.”

Although the antibody-drug conjugate brentuximab vedotin has been considered the standard of care for patients with relapse after autologous SCT, there has historically been no standard of care for patients who are ineligible for transplant because of chemorefractory disease, advanced age, or comorbidities, Dr. Kuruvilla said in his presentation.

In the KEYNOTE-204 study, 304 patients with relapsed/refractory classic Hodgkin lymphoma were randomized to receive either pembrolizumab 200 mg or brentuximab at 1.8 mg/kg intravenously every 3 weeks for up to 35 cycles.

The median age of patients was 36 years in the pembrolizumab arm and 35 years in the brentuximab vedotin arm, according to the report. Approximately 37% of the patients had previously undergone autologous SCT. About 40% had been refractory to frontline therapy, while 28% relapsed within 12 months of therapy and 32% relapsed later than 12 months.

Median PFS by blinded independent central review was 13.2 versus 8.3 months in the pembrolizumab and brentuximab arms, respectively (hazard ratio, 0.65; 95% confidence interval, 0.48-0.88; P = .00271), Dr. Kuruvilla reported.

Nearly one in five individuals with cancer who are treated with immune checkpoint inhibitors develop thyroid dysfunction, new research suggests.

Sebastian Kaulitzki/Fotolia

Immune checkpoint inhibitors have revolutionized the treatment of many different types of cancers, but can also trigger a variety of immune-related adverse effects. As these drugs become more widely used, rates of these events appear to be more common in the real-world compared with clinical trial settings.

In their new study, Zoe Quandt, MD, of the University of California, San Francisco (UCSF), and colleagues specifically looked at thyroid dysfunction in their own institution’s EHR data and found more than double the rate of hypothyroidism and more than triple the rate of hyperthyroidism, compared with rates in published trials.

Moreover, in contrast to previous studies that have found differences in thyroid dysfunction by checkpoint inhibitor type, Dr. Quandt and colleagues instead found significant differences by cancer type.

Dr. Quandt presented the findings during a virtual press briefing held March 31originally scheduled for ENDO 2020.

“Thyroid dysfunction following checkpoint inhibitor therapy appears to be much more common than was previously reported in clinical trials, and this is one of the first studies to show differences by cancer type rather than by checkpoint inhibitor type,” Dr. Quandt said during the presentation.

However, she also cautioned that there’s “a lot more research to be done to validate case definitions and validate these findings.”

Asked to comment, endocrinologist David C. Lieb, MD, associate professor of medicine at Eastern Virginia Medical School in Norfolk, said in an interview, “These drugs are becoming so much more commonly used, so it’s not surprising that we’re seeing more endocrine complications, especially thyroid disease.”

“Endocrinologists need to work closely with oncologists to make sure patients are being screened and followed appropriately.”

‘A much higher percentage than we were expecting’

Dr. Quandt’s study included 1,146 individuals treated with checkpoint inhibitors at UCSF during 2012-2018 who did not have thyroid cancer or preexisting thyroid dysfunction.

Pembrolizumab (Keytruda) was the most common treatment (45%), followed by nivolumab (Opdivo) (20%). Less than 10% of patients received atezolizumab (Tecentriq), durvalumab (Imfizi), ipilimumab (Yervoy) monotherapy, combined ipilimumab/nivolumab, or other combinations of checkpoint inhibitors.

A total of 19.1% developed thyroid disease, with 13.4% having hypothyroidism and 9.5% hyperthyroidism. These figures far exceed those found in a recent meta-analysis of 38 randomized clinical trials of checkpoint inhibitors that included 7551 patients.

“Using this approach, we found a much higher percentage of patients who developed thyroid dysfunction than we were expecting,” Dr. Quandt said.

In both cases, the two categories – hypothyroidism and hyperthyroidism – aren’t mutually exclusive as hypothyroidism can arise de novo or subsequent to hyperthyroidism.

Dr Lieb commented, “It would be interesting to see what the causes of hyperthyroidism are – thyroiditis or Graves disease.”

Dr. Quandt mentioned a possible reason for the large difference between clinical trial and real-world data.

“Once we’re actually using these drugs outside of clinical trials, some of the restrictions about using them in people with other autoimmune diseases have been lifted, so my guess is that as we give them to a broader population we’re seeing more of these [adverse effects],” she suggested.

Also, “In the initial trials, people weren’t quite as aware of the possibilities of these side effects, so now we’re doing many more labs. Patients get thyroid function tests with every infusion, so I think we’re probably catching more patients who develop disease.”
 

Differences by cancer type, not checkpoint inhibitor type

And in a new twist, Dr. Quandt found that, in contrast to the differences seen by checkpoint inhibitor type in randomized trials, “surprisingly, we found that this difference did not reach statistical significance.”

“Instead, we saw that cancer type was associated with development of thyroid dysfunction, even after taking checkpoint inhibitor type into account.”

The percentages of patients who developed thyroid dysfunction ranged from 9.7% of those with glioblastoma to 40.0% of those with renal cell carcinoma.

The reason for this is not clear, said Dr. Quandt in an interview.

One possibility relates to other treatments patients with cancer also receive. In renal cell carcinoma, for example, patients also are treated with tyrosine kinase inhibitors, which can also cause thyroid dysfunction, so they may be more susceptible. Or there may be shared antigens activating the immune system.

“That’s definitely one of the questions we’re looking at,” she said.

Dr. Quandt and Dr. Lieb have reported no relevant financial relationships.

A patient with HIV remission induced by stem cell transplantation continues to be disease free at the 30-month mark.

The individual, referred to as the London patient, received allogeneic hematopoietic stem cell transplantation (allo-HSCT) for stage IVB Hodgkin lymphoma. The transplant donor was homozygous for the CCR5 delta-32 mutation, which confers immunity to HIV because there’s no point of entry for the virus into immune cells.

After extensive sampling of various tissues, including gut, lymph node, blood, semen, and cerebrospinal fluid (CSF), Ravindra Kumar Gupta, MD, PhD, and colleagues found no detectable virus that was competent to replicate. However, they reported that the testing did detect some “fossilized” remnants of HIV DNA persisting in certain tissues.

The results were shared in a video presentation of the research during the Conference on Retroviruses & Opportunistic Infections, which was presented online this year. CROI organizers chose to hold a virtual meeting because of concerns about the spread of COVID-19.

The London patient’s HIV status had been reported the previous year at CROI 2019, but only blood samples were used in that analysis.

In a commentary accompanying the simultaneously published study in the Lancet, Jennifer Zerbato, PhD, and Sharon Lewin, FRACP, PHD, FAAHMS, asked: “A key question now for the area of HIV cure is how soon can one know if someone has been cured of HIV?

“We will need more than a handful of patients cured of HIV to really understand the duration of follow-up needed and the likelihood of an unexpected late rebound in virus replication,” continued Dr. Zerbato, of the University of Melbourne, and Dr. Lewin, of the Royal Melbourne Hospital and Monash University, also in Melbourne.

In their ongoing analysis of data from the London patient, Dr. Gupta, a virologist at the University of Cambridge (England), and associates constructed a mathematical model that maps the probability for lifetime remission or cure of HIV against several factors, including the degree of chimerism achieved with the stem cell transplant.

In this model, when chimerism reaches 80% in total HIV target cells, the probability of remission for life is 98%; when donor chimerism reaches 90%, the probability of lifetime remission is greater than 99%. Peripheral T-cell chimerism in the London patient has held steady at 99%.

Dr. Gupta and associates obtained some testing opportunistically: A PET-CT scan revealed an axillary lymph node that was biopsied after it was found to have avid radiotracer uptake. Similarly, the CSF sample was obtained in the course of a work-up for some neurologic symptoms that the London patient was having.

In contrast to the first patient who achieved ongoing HIV remission from a pair of stem cell transplants received over 13 years ago – the Berlin patient – the London patient did not receive whole-body radiation, but rather underwent a reduced-intensity conditioning regimen. The London patient experienced a bout of gut graft-versus-host disease (GVHD) about 2 months after his transplant, but has been free of GVHD in the interval. He hasn’t taken cytotoxic agents or any GVHD prophylaxis since 6 months post transplant.

Though there’s no sign of HIV that’s competent to replicate, “the London patient has shown somewhat slow CD4 reconstitution,” said Dr. Gupta and coauthors in discussing the results.

The patient had a reactivation of Epstein-Barr virus (EBV) about 21 months after analytic treatment interruption (ATI) of antiretroviral therapy that was managed without any specific treatment, but he hasn’t experienced any opportunistic infections. However, his CD4 count didn’t rebound to pretransplant levels until 28 months after ATI. At that point, his CD4 count was 430 cells per mcL, or 23.5% of total T cells. The CD4:CD8 ratio was 0.86; normal range is 1.5-2.5.

The researchers used quantitative real-time polymerase chain reaction (rt-PCR) to look for packaging site and envelope (env) DNA fragments, and droplet digital PCR to quantify HIV-1 DNA.

The patient’s HIV-1 plasma load measured at 30 months post ATI on an ultrasensitive assay was below the lower limit of detection (less than 1 copy per mL). Semen viremia measured at 21 months was also below the lower limit of detection, as was CSF measured at 25 months.

Samples were taken from the patient’s rectum, cecum, sigmoid colon, and terminal ileum during a colonoscopy conducted 22 months post ATI; all tested negative for HIV DNA via droplet digital PCR.

The lymph node had large numbers of EBV-positive cells and was positive for HIV-1 env and long-terminal repeat by double-drop PCR, but no integrase DNA was detected. Additionally, no intact proviral DNA was found on assay.

Dr. Gupta and associates speculated that “EBV reactivation could have triggered EBV-specific CD4 and CD8 T-cell responses and proliferation, potentially including CD4 T cells containing HIV-1 DNA.” Supporting this hypothesis, EBV-specific CD8 T-cell responses in peripheral blood were “robust,” and the researchers also saw some CD4 response.

“Similar to the Berlin patient, highly sensitive tests showed very low levels of so-called fossilized HIV-1 DNA in some tissue samples from the London patient. Residual HIV-1 DNA and axillary lymph node tissue could represent a defective clone that expanded during hyperplasia within the lymph note sampled,” noted Dr. Gupta and coauthors.

Responses of CD4 and CD8 T cells to HIV have also remained below the limit of detection, though cytomegalovirus-specific responses persist in the London patient.

As with the Berlin patient, standard enzyme-linked immunosorbent assay (ELISA) testing has remained positive in the London patient. “Standard ELISA testing, therefore, cannot be used as a marker for cure, although more work needs to be done to assess the role of detuned low-avidity antibody assays in defining cure,” noted Dr. Gupta and associates.

The ongoing follow-up plan for the London patient is to obtain viral load testing twice yearly up to 5 years post ATI, and then obtain yearly tests for a total of 10 years. Ongoing testing will confirm the investigators’ belief that “these findings probably represent the second recorded HIV-1 cure after CCR5 delta-32/delta-32 allo-HSCT, with evidence of residual low-level HIV-1 DNA.”

Dr. Zerbato and Dr. Lewin advised cautious optimism and ongoing surveillance: “In view of the many cells sampled in this case, and the absence of any intact virus, is the London patient truly cured? The additional data provided in this follow-up case report is certainly exciting and encouraging but, in the end, only time will tell.”

Dr. Gupta reported being a consultant for ViiV Healthcare and Gilead Sciences; several coauthors also reported financial relationships with pharmaceutical companies. The work was funded by amfAR, the American Foundation for AIDS Research, and the Wellcome Trust. Dr. Lewin reported grants from the National Health and Medical Research Council of Australia, the National Institutes of Health, the American Foundation for AIDS Research, Gilead Sciences, Merck, ViiV Healthcare, Leidos, the Wellcome Trust, the Australian Centre for HIV and Hepatitis Virology Research, and the Melbourne HIV Cure Consortium.

Responses of CD4 and CD8 T cells to HIV have also remained below the limit of detection, though cytomegalovirus-specific responses persist in the London patient.

As with the Berlin patient, standard enzyme-linked immunosorbent assay (ELISA) testing has remained positive in the London patient. “Standard ELISA testing, therefore, cannot be used as a marker for cure, although more work needs to be done to assess the role of detuned low-avidity antibody assays in defining cure,” noted Dr. Gupta and associates.

The ongoing follow-up plan for the London patient is to obtain viral load testing twice yearly up to 5 years post ATI, and then obtain yearly tests for a total of 10 years. Ongoing testing will confirm the investigators’ belief that “these findings probably represent the second recorded HIV-1 cure after CCR5 delta-32/delta-32 allo-HSCT, with evidence of residual low-level HIV-1 DNA.”

Dr. Zerbato and Dr. Lewin advised cautious optimism and ongoing surveillance: “In view of the many cells sampled in this case, and the absence of any intact virus, is the London patient truly cured? The additional data provided in this follow-up case report is certainly exciting and encouraging but, in the end, only time will tell.”

A patient with HIV remission induced by stem cell transplantation continues to be disease free at the 30-month mark.

The individual, referred to as the London patient, received allogeneic hematopoietic stem cell transplantation (allo-HSCT) for stage IVB Hodgkin lymphoma. The transplant donor was homozygous for the CCR5 delta-32 mutation, which confers immunity to HIV because there’s no point of entry for the virus into immune cells.

After extensive sampling of various tissues, including gut, lymph node, blood, semen, and cerebrospinal fluid (CSF), Ravindra Kumar Gupta, MD, PhD, and colleagues found no detectable virus that was competent to replicate. However, they reported that the testing did detect some “fossilized” remnants of HIV DNA persisting in certain tissues.

The results were shared in a video presentation of the research during the Conference on Retroviruses & Opportunistic Infections, which was presented online this year. CROI organizers chose to hold a virtual meeting because of concerns about the spread of COVID-19.

The London patient’s HIV status had been reported the previous year at CROI 2019, but only blood samples were used in that analysis.

In a commentary accompanying the simultaneously published study in the Lancet, Jennifer Zerbato, PhD, and Sharon Lewin, FRACP, PHD, FAAHMS, asked: “A key question now for the area of HIV cure is how soon can one know if someone has been cured of HIV?

“We will need more than a handful of patients cured of HIV to really understand the duration of follow-up needed and the likelihood of an unexpected late rebound in virus replication,” continued Dr. Zerbato, of the University of Melbourne, and Dr. Lewin, of the Royal Melbourne Hospital and Monash University, also in Melbourne.

In their ongoing analysis of data from the London patient, Dr. Gupta, a virologist at the University of Cambridge (England), and associates constructed a mathematical model that maps the probability for lifetime remission or cure of HIV against several factors, including the degree of chimerism achieved with the stem cell transplant.

In this model, when chimerism reaches 80% in total HIV target cells, the probability of remission for life is 98%; when donor chimerism reaches 90%, the probability of lifetime remission is greater than 99%. Peripheral T-cell chimerism in the London patient has held steady at 99%.

Dr. Gupta and associates obtained some testing opportunistically: A PET-CT scan revealed an axillary lymph node that was biopsied after it was found to have avid radiotracer uptake. Similarly, the CSF sample was obtained in the course of a work-up for some neurologic symptoms that the London patient was having.

In contrast to the first patient who achieved ongoing HIV remission from a pair of stem cell transplants received over 13 years ago – the Berlin patient – the London patient did not receive whole-body radiation, but rather underwent a reduced-intensity conditioning regimen. The London patient experienced a bout of gut graft-versus-host disease (GVHD) about 2 months after his transplant, but has been free of GVHD in the interval. He hasn’t taken cytotoxic agents or any GVHD prophylaxis since 6 months post transplant.

Though there’s no sign of HIV that’s competent to replicate, “the London patient has shown somewhat slow CD4 reconstitution,” said Dr. Gupta and coauthors in discussing the results.

The patient had a reactivation of Epstein-Barr virus (EBV) about 21 months after analytic treatment interruption (ATI) of antiretroviral therapy that was managed without any specific treatment, but he hasn’t experienced any opportunistic infections. However, his CD4 count didn’t rebound to pretransplant levels until 28 months after ATI. At that point, his CD4 count was 430 cells per mcL, or 23.5% of total T cells. The CD4:CD8 ratio was 0.86; normal range is 1.5-2.5.

The researchers used quantitative real-time polymerase chain reaction (rt-PCR) to look for packaging site and envelope (env) DNA fragments, and droplet digital PCR to quantify HIV-1 DNA.

The patient’s HIV-1 plasma load measured at 30 months post ATI on an ultrasensitive assay was below the lower limit of detection (less than 1 copy per mL). Semen viremia measured at 21 months was also below the lower limit of detection, as was CSF measured at 25 months.

Samples were taken from the patient’s rectum, cecum, sigmoid colon, and terminal ileum during a colonoscopy conducted 22 months post ATI; all tested negative for HIV DNA via droplet digital PCR.

The lymph node had large numbers of EBV-positive cells and was positive for HIV-1 env and long-terminal repeat by double-drop PCR, but no integrase DNA was detected. Additionally, no intact proviral DNA was found on assay.

Dr. Gupta and associates speculated that “EBV reactivation could have triggered EBV-specific CD4 and CD8 T-cell responses and proliferation, potentially including CD4 T cells containing HIV-1 DNA.” Supporting this hypothesis, EBV-specific CD8 T-cell responses in peripheral blood were “robust,” and the researchers also saw some CD4 response.

“Similar to the Berlin patient, highly sensitive tests showed very low levels of so-called fossilized HIV-1 DNA in some tissue samples from the London patient. Residual HIV-1 DNA and axillary lymph node tissue could represent a defective clone that expanded during hyperplasia within the lymph note sampled,” noted Dr. Gupta and coauthors.

Responses of CD4 and CD8 T cells to HIV have also remained below the limit of detection, though cytomegalovirus-specific responses persist in the London patient.

Brentuximab vedotin plus doxorubicin, vinblastine, and dacarbazine (A+AVD) provides “robust, sustained efficacy” in patients with Hodgkin lymphoma, according to investigators.

In the ECHELON-1 trial, investigators compared A+AVD to doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) as frontline treatment for stage III or IV Hodgkin lymphoma. The 3-year progression-free survival (PFS) was superior in patients who received A+AVD, and this benefit was seen across most subgroups.

David J. Straus, MD, of Memorial Sloan Kettering Cancer Center in New York and his colleagues detailed these findings in Blood.

The phase 3 trial (NCT01712490) enrolled 1,334 patients with stage III or IV classical Hodgkin lymphoma. They were randomized to receive A+AVD (n = 664) or ABVD (n = 670). Baseline characteristics were similar between the treatment arms.

Positron emission tomography status after cycle 2 (PET2) was similar between the treatment arms as well. Most patients – 89% of the A+AVD arm and 86% of the ABVD arm – were PET2 negative. Treating physicians used PET2 status as a guide to potentially switch patients to an alternative regimen (radiotherapy or chemotherapy with or without transplant).

In a prior analysis, the study’s primary endpoint was modified PFS (time to progression, death, or noncomplete response after frontline therapy) per an independent review committee (N Engl J Med. 2018;378:331-44). The 2-year modified PFS rate was 82.1% in the A+AVD arm and 77.2% in the ABVD arm (hazard ratio, 0.77; P = .04).

PFS update

In the current analysis, the main exploratory endpoint was PFS per investigator. The 3-year PFS rate was significantly higher in the A+AVD arm than in the ABVD arm – 83.1% and 76.0%, respectively (HR, 0.704; P = .005).

The investigators observed a “consistent improvement in PFS” in the A+AVD arm, regardless of disease stage, International Prognostic score, Eastern Cooperative Oncology Group status, sex, or age. There was a significant improvement in PFS with A+AVD in PET2-negative patients and a trend toward improvement in PET2-positive patients. In the PET2-negative patients, the 3-year PFS was 85.8% in the A+AVD arm and 79.5% in the ABVD arm (HR, 0.69; P = .009). In PET2-positive patients, the 3-year PFS was 67.7% and 51.5%, respectively (HR, 0.59; P = .077).

“These data highlight that A+AVD provides a durable efficacy benefit, compared with ABVD, for frontline stage III/IV cHL [classical Hodgkin lymphoma], which is consistent across key subgroups regardless of patient status at PET2,” Dr. Straus and his colleagues wrote.

Safety update

In both treatment arms, peripheral neuropathy continued to improve or resolve with longer follow-up. Among patients who developed peripheral neuropathy, 78% in the A+AVD arm and 83% in the ABVD arm had improvement or resolution of the condition at 3 years.

Most patients had complete resolution of peripheral neuropathy; 62% in the A+AVD arm and 73% in the ABVD arm. The median time to complete resolution was 28 weeks (range, 0-167 weeks) after stopping A+AVD and 14 weeks (range, 0-188 weeks) after stopping ABVD.

The incidence of secondary malignancies was similar between the treatment arms. There were 14 secondary malignancies in the A+AVD arm (6 solid tumors, 8 hematologic malignancies) and 20 in the ABVD arm (9 solid tumors, 11 hematologic malignancies).

“A+AVD provided a sustained PFS benefit with a predictable and manageable safety profile,” Dr. Straus and colleagues wrote. “These data further support the advantages of A+AVD versus ABVD as frontline treatment of patients with advanced stage III or IV cHL [classical Hodgkin lymphoma].”

The ECHELON-1 trial was sponsored by Millennium Pharmaceuticals (a subsidiary of Takeda) and Seattle Genetics. The investigators disclosed relationships with Millennium, Takeda, Seattle Genetics, and a range of other companies.

Adult survivors of pediatric cancers appear to be experiencing fewer major cardiac events in adulthood partly because of reduced radiotherapy exposure, especially among survivors of Hodgkin lymphoma, recent research published in BMJ has shown.

“Contemporary cancer treatment has focused on advancing cure rates while attempting to minimize long term adverse effects,” Daniel A. Mulrooney, MD, of the Division of Cancer Survivorship, Department of Oncology, at St. Jude Children’s Research Hospital, Arlington, Va., and colleagues wrote. “Patterns of exposure to cardiotoxic treatment have changed over time, with fewer children receiving chest directed radiation, with lower doses and smaller volumes for those who do, and an increased use of anthracyclines, albeit with reduced cumulative doses as the risk for late-onset heart failure became apparent.”

Although research has been published on improved survival rates of children who underwent cancer treatment in the 1990s, compared with those who received treatment in the 1980s and 1970s, Dr. Mulrooney and colleagues set out to determine whether cardiac outcomes were reduced as well. They conducted a retrospective study of 23,462 5-year survivors of pediatric cancer, which consisted of leukemia, brain cancer, Hodgkin lymphoma, non-Hodgkin lymphoma, renal tumors, neuroblastoma, soft-tissue sarcomas, and bone sarcomas diagnosed between January 1970 and December 1999. Researchers compared the cardiac outcomes of the survivors, including heart failure, coronary artery disease, valvular heart disease, pericardial disease, and arrhythmias, with a comparison group of their siblings (n = 5,057) separated by decade. The adult survivors tended to be women (46% vs. 40%) with a median age of 6.1 years at diagnosis and 27.7 years at final follow-up.

Of the 6,193 participants treated for cancer in the 1970s, the 20-year cumulative incidence of heart failure was 0.69%, while the 9,363 participants treated in the 1980s had an incidence of 0.74%, and 7,906 participants in the 1990s had a cumulative incidence of 0.54% over 20 years. The 20-year cumulative incidence for coronary artery disease (CAD) was 0.38% for participants in the 1970s, 0.24% for participants in the 1980s, and 0.19% for participants in the 1990s (P less than .01). Researchers noted the 20-year cumulative incidence of valvular disease, pericardial disease, and arrhythmias did not decrease between the 1970s and the 1990s.

When comparing the rate of major cardiac events of participants in the 1980s and 1990s with those of the 1970s, CAD diagnoses significantly decreased in the 1980s (hazard ratio, 0.65; 95% confidence interval, 0.45-0.92) and 1990s (HR, 0.53; 95% CI, 0.36-0.77), while there was no significant decrease in heart failure or valvular heart disease risk over time. After adjusting for cardiac radiation, overall risk for CAD was attenuated (HR, 0.90; 0.78-1.05), and Hodgkin lymphoma survivors saw the greatest change between unadjusted (HR, 0.77; 95% CI, 0.66-0.89) and adjusted risk (HR, 0.87; 95% CI, 0.69-1.10) when accounting for cardiac radiation.

“While additional longitudinal follow-up is needed to establish whether similar reductions in the cumulative incidence of heart failure can be confirmed in multivariable analysis, these results suggest that efforts to modify cancer therapies in children and promote health surveillance for survivors are beginning to show benefits not only in overall survival but also in late adverse cardiac effects,” the researchers concluded.

In a related editorial, Mike Hawkins, DPhil, of the Centre for Childhood Cancer Survivor Studies, Institute of Applied Health Research at the University of Birmingham (England), and colleagues said that, while measuring cardiotoxicity is important for this patient population, traditional risk factors with independent associations to cardiac outcomes should also be studied. Guidelines on follow-up for these patients are also needed to inform clinical practice, such as those produced by the International Late Effects of Childhood Cancer Guideline Harmonization Group, they added.

“Survivorship issues are extremely important to patients, their families, and their doctors,” they said. “In two research priority setting initiatives in the United Kingdom, detailed consultation with patients with cancer, survivors, families, friends, and healthcare professionals identified further research into the consequences of cancer as a top priority.”

This study was funded by grants from the National Cancer Institute, Cancer Center Support (CORE) to St. Jude Children’s Research Hospital and American Lebanese Syrian Associated Charities. The authors of the study and the editorial reported no relevant conflicts of interest.

Although research has been published on improved survival rates of children who underwent cancer treatment in the 1990s, compared with those who received treatment in the 1980s and 1970s, Dr. Mulrooney and colleagues set out to determine whether cardiac outcomes were reduced as well. They conducted a retrospective study of 23,462 5-year survivors of pediatric cancer, which consisted of leukemia, brain cancer, Hodgkin lymphoma, non-Hodgkin lymphoma, renal tumors, neuroblastoma, soft-tissue sarcomas, and bone sarcomas diagnosed between January 1970 and December 1999. Researchers compared the cardiac outcomes of the survivors, including heart failure, coronary artery disease, valvular heart disease, pericardial disease, and arrhythmias, with a comparison group of their siblings (n = 5,057) separated by decade. The adult survivors tended to be women (46% vs. 40%) with a median age of 6.1 years at diagnosis and 27.7 years at final follow-up.

Of the 6,193 participants treated for cancer in the 1970s, the 20-year cumulative incidence of heart failure was 0.69%, while the 9,363 participants treated in the 1980s had an incidence of 0.74%, and 7,906 participants in the 1990s had a cumulative incidence of 0.54% over 20 years. The 20-year cumulative incidence for coronary artery disease (CAD) was 0.38% for participants in the 1970s, 0.24% for participants in the 1980s, and 0.19% for participants in the 1990s (P less than .01). Researchers noted the 20-year cumulative incidence of valvular disease, pericardial disease, and arrhythmias did not decrease between the 1970s and the 1990s.

When comparing the rate of major cardiac events of participants in the 1980s and 1990s with those of the 1970s, CAD diagnoses significantly decreased in the 1980s (hazard ratio, 0.65; 95% confidence interval, 0.45-0.92) and 1990s (HR, 0.53; 95% CI, 0.36-0.77), while there was no significant decrease in heart failure or valvular heart disease risk over time. After adjusting for cardiac radiation, overall risk for CAD was attenuated (HR, 0.90; 0.78-1.05), and Hodgkin lymphoma survivors saw the greatest change between unadjusted (HR, 0.77; 95% CI, 0.66-0.89) and adjusted risk (HR, 0.87; 95% CI, 0.69-1.10) when accounting for cardiac radiation.

“While additional longitudinal follow-up is needed to establish whether similar reductions in the cumulative incidence of heart failure can be confirmed in multivariable analysis, these results suggest that efforts to modify cancer therapies in children and promote health surveillance for survivors are beginning to show benefits not only in overall survival but also in late adverse cardiac effects,” the researchers concluded.

In a related editorial, Mike Hawkins, DPhil, of the Centre for Childhood Cancer Survivor Studies, Institute of Applied Health Research at the University of Birmingham (England), and colleagues said that, while measuring cardiotoxicity is important for this patient population, traditional risk factors with independent associations to cardiac outcomes should also be studied. Guidelines on follow-up for these patients are also needed to inform clinical practice, such as those produced by the International Late Effects of Childhood Cancer Guideline Harmonization Group, they added.

“Survivorship issues are extremely important to patients, their families, and their doctors,” they said. “In two research priority setting initiatives in the United Kingdom, detailed consultation with patients with cancer, survivors, families, friends, and healthcare professionals identified further research into the consequences of cancer as a top priority.”

This study was funded by grants from the National Cancer Institute, Cancer Center Support (CORE) to St. Jude Children’s Research Hospital and American Lebanese Syrian Associated Charities. The authors of the study and the editorial reported no relevant conflicts of interest.

Vitamin D deficiency is associated with worse progression-free and overall survival among patients with Hodgkin lymphoma, according to new study findings.

Sven Borchmann, MD, of the University of Cologne (Germany) and German Hodgkin Study Group and coauthors conducted a case-control study of 351 patients enrolled in the German Hodgkin Study Group trials who had available baseline serum samples. Pretreatment vitamin D levels were assessed and categorized as deficient (less than 30 nmol/L), insufficient (30-49 nmol/L), or sufficient (50 nmol/L or greater). The findings were published in the Journal of Clinical Oncology.

The researchers found that before starting treatment, 50% of patients were vitamin D deficient.

Patients with baseline vitamin D deficiency had significantly lower progression-free survival – 10.2% lower at 5 years and 17.6% lower at 10 years – compared with patients with either sufficient or insufficient vitamin D levels (P less than .001). They also had 2% lower overall survival at 5 years and 11.1% lower overall survival at 10 years (P less than .001).

The researchers also conducted preclinical studies in effort to understand the effect of vitamin D on Hodgkin lymphoma cells and in Hodgkin lymphoma tumor models.

They explored the effect of vitamin D on cultured Hodgkin lymphoma cell lines and saw a dose-response effect of calcitriol in reducing cell proliferation rates. They then looked at the effect of calcitriol on cell lines that were also exposed to doxorubicin or etoposide, and found calcitriol improved the cytotoxicity of these chemotherapy agents, especially at lower doses.

Finally, they conducted an in-vivo mouse study using Hodgkin lymphoma xenografts, and looked at whether vitamin D supplementation increased the effect of doxorubicin or etoposide. This revealed that chemotherapy and vitamin D supplementation together were significantly better at controlling tumor growth, compared with monotherapy with either vitamin D or doxorubicin and compared with placebo.

“On the basis of our study results and the limited toxicity of vitamin D replacement therapy, we would advocate for vitamin D deficiency screening and replacement to be incorporated into future randomized clinical trials to properly clarify the role of vitamin D replacement in HL [Hodgkin lymphoma],” the researchers wrote. “The goal of these trials should be to determine whether vitamin D replacement in HL improves outcome.”

No study funding information was reported. Dr. Borchmann reported honoraria and research funding from Takeda. Other authors reported financial disclosures related to Takeda, Roche, Bristol-Myers Squibb, and other companies.
