Five-minute SC injection of daratumumab in RRMM
Data from the Apollo study provide proof for the subcutaneous administration (SC) of daratumumab (Darzalex Faspro) in combination with pomalidomide (Pomalyst) and dexamethasone (Pd) for patients with relapsed or refractory multiple myeloma (RRMM).
The SC formulation of daratumumab (with hyaluronidase) was approved in the United States in May, and is administered by injection into the abdomen over 3-5 minutes. Previously the drug was available only as an intravenous infusion.
“The appeal of subcutaneous daratumumab is the 5 minutes it needs for administering, cutting down considerable on ‘chair/clinic’ time. Intravenous daratumumab is given over several hours,” said Joseph Mikhael, MD, MEd, chief medical officer of the International Myeloma Foundation. He also highlighted the low rates of infusion reactions seen with the subcutaneous daratumumab triplet.
“In the COVID era the subcutaneous route may be the way to go,” he said in an interview.
“This is an effective combination with a predictable safety profile that allows for the use of SC daratumumab along with oral pomalidomide and dexamethasone for patients who have received at least one prior line of therapy that included lenalidomide [Revlimid] and a proteasome inhibitor,” commented lead author Meletios A. Dimopoulos, MD, of the National and Kapodistrian University of Athens.
The triplet combination was associated with a 37% reduced risk for progression or death, compared with the two-drug combination of pomalidomide and dexamethasone.
He presented the results from the Apollo trial at the annual meeting of the American Society of Hematology.
Treatment landscape of RRMM
Dr. Mikhael, who is also professor in the applied cancer research and drug discovery division at the Translational Genomics Research Institute, Phoenix, provided his insights into Apollo as well as how this triplet fits into the treatment landscape of RRMM.
Daratumumab is approved for use in both RRMM and newly diagnosed MM, either alone or in combination with standard-of-care regimens. The drug already has eight specific indications for the intravenous formulation, and five indications for the SC formulation of daratumumab, Dr. Mikhael noted. The Apollo study “will likely provide the subcutaneous approval for the daratumumab triplet in MM.”
According to Dr. Mikhael, the triplet of daratumumab with pomalidomide and dexamethasone is the most commonly used combination at first relapse, and this phase 3 study provides confirmatory evidence for its initial approval. The initial approval for intravenous daratumumab and Pd was based on a phase 1b study, he noted.
“The Apollo study is the first randomized trial comparing the triplet of D-Pd to Pd,” Noopur Raje, MD, of the Massachusetts General Hospital, Boston, said in an interview. She explained that the majority of patients included in Apollo were refractory to lenalidomide, which is the patient population typically seen at the time of first relapse. “This regimen will be adopted at either first or second relapse in the majority of patients,” Dr. Raje said.
“In keeping with strategy in MM, we use the best triplet first and do not save the best for last,” Dr. Mikhael said. The triplet of the proteasome inhibitor bortezomib (Velcade), lenalidomide, and dexamethasone is used in first-line MM. “Most patients meet the criteria for using D-Pd at first relapse,” he added, noting that all patients in the study have received a proteasome inhibitor and lenalidomide as first-line therapy and had relapsed with or were refractory to these agents.
“The short administration time and significantly low rates of infusion-site reactions are two important considerations for using this triplet with the subcutaneous formulation of daratumumab [at first relapse],” he said.
In the treatment landscape of MM, the triplet of isatuximab (Sarclisa), pomalidomide, and dexamethasone has recently been approved for RRMM based on data from the ICARIA study. Isatuximab and daratumumab are both CD38-directed antibodies. Dr. Mikhael pointed out that the datasets from ICARIA and Apollo with respect to progression-free survival (PFS) and hazard ratios overlapped and were remarkably similar. However, daratumumab now has an advantage in being available as an SC formulation.
The landscape of MM treatment has been changing rapidly in recent years, and more changes may be afoot. Dr. Mikhael suggested that the quartet of daratumumab, bortezomib, lenalidomide, and dexamethasone is likely to move into the first-line setting for MM based on data from the GRIFFIN study (trial update in Abstract 3243), and then the choice of drugs to use in first relapse would also change.
Apollo study details
Apollo was an open-label, phase 3 study that randomly assigned patients with RRMM to receive SC daratumumab in combination with pomalidomide and low-dose dexamethasone (D-Pd; n = 151) or the two-drug combination of Pd (n = 153).
Approximately 80% of the patients were refractory to lenalidomide and half were refractory to a proteasome inhibitor.
Median duration of SC daratumumab administration was 5 minutes. Median duration of study treatment was longer for patients on D-Pd (11.5 months vs. 6.6 months for Pd).
For the primary endpoint, at a median follow up of 16.9 months, median PFS was 12.4 months for patients receiving D-Pd and 6.9 months for those receiving Pd. One-year PFS was 52% for patients receiving the triplet combination and 35% for those receiving Pd. Treatment effect was generally consistent across subgroups examined, Dr. Dimopoulos reported.
Depth of response was significantly higher for patients on D-Pd. Stringent complete remission or CR was seen in 25% of patients on D-Pd versus 4% on Pd. Overall response rate was 69% for patients on D-Pd and 45% for patients on Pd alone (P < .0001). Minimal residual disease negativity was more than four times higher with D-Pd (9% vs. 2% for Pd; P = .0102).
The safety profile of D-Pd was consistent with the known safety profile of SC daratumumab and Pd. Infusion-site reactions were grade 1-2 and occurred in 5% of patients; in addition, only grade 1 injection-site reactions were seen and occurred in 2% of patients. The most serious treatment-emergent adverse events in patients on D-Pd were pneumonia (15% vs. 8% for Pd) and lower respiratory tract infection (12% vs. 9% for Pd). Incidence of secondary primary malignancy was 2% for each group.
Apollo results were ‘no surprise’
“These results are of no surprise and further support the current practice of using a three-drug combination in the relapsed setting,” Henry Fung, MD, chair of the department of bone marrow transplant and cellular therapies at Fox Chase Cancer Center, Philadelphia, said in an interview.
Although Dr. Fung agreed that the triplet of a proteasome inhibitor, an immunomodulating drug such as lenalidomide, and the steroid dexamethasone is becoming the standard of care for newly diagnosed MM, D-Pd should be considered an excellent option for patients who have limited choices in the relapsed/refractory setting.
However, he said that the median PFS of 12.4 months for patients receiving D-Pd after a median of two prior regimens is not satisfactory.
“The impact on the natural history of the disease will be limited and the duration of responses decline with each treatment regimen, and the true impact on the disease will be an effective frontline strategy.” Dr. Fung said. “This will not be a practice-changing trial. We need to find out which three-drug regimen works best and what biomarkers can predict the response to individual regimen.”

Duvelisib response rate encouraging in phase 2 PRIMO trial of patients with r/r PTCL
Duvelisib is demonstrating encouraging activity and manageable toxicities among patients with relapsed/refractory peripheral T-cell lymphoma (PTCL) in a phase 2 trial, an investigator said.
The overall response rate in the dose-optimization phase of the PRIMO trial was more than 60% among patients receiving 75 mg of duvelisib twice daily, with a median duration of response exceeding 12 months, said investigator Barbara Pro, MD, of Northwestern University, Chicago.
In the ongoing dose-expansion phase, in which patients start on 75 mg twice daily and then transition to a lower dose, the ORR is over 50%, including complete responses (CRs) in about one-third of patients, Dr. Pro reported at the annual meeting of the American Society of Hematology.
Most previously approved treatments for relapsed/refractory PTCL are associated with ORRs of less than 30%, low rates of CR, and median progression-free survival of less than 4 months, Dr. Pro said in her presentation.
There have been no unexpected toxicities in the dose-expansion phase, and the adverse event profile is consistent with what has been observed previously for this oral phosphatidylinositol 3-kinase (PI3K) inhibitor, according to Dr. Pro.
Based on results to date, Dr. Pro said she and coinvestigators are hopeful that duvelisib will have a place in the treatment armamentarium for relapsed/refractory PTCL in the future.
“This is one of the most effective agents in T-cell lymphoma, and hopefully will be approved and available for treatment soon,” she said in remarks following her presentation of PRIMO study data.
“The next question would be how to try to move this agent up front,” she added. “We’ll have to try to see what could be the possible combinations and evaluate the possible overlapping toxicity with alternative treatments.”
The PRIMO trial provides “very exciting numbers” that include roughly half of relapsed/refractory PTCL patients are responding to the oral therapy, said Andrei R. Shustov, MD, professor of medicine in the division of hematology at the University of Washington, Seattle.
Perhaps more importantly, at least half of those responses have been CRs, Dr. Shustov noted in an interview: “We haven’t seen this yet in T-cell lymphomas, short of brentuximab vedotin targeting CD30,” he said, referring to the 2018 Food and Drug Administration approval of brentuximab vedotin for previously untreated CD30-expressing PTCL.
If duvelisib is approved, it would be the first oral agent with an indication for relapsed/refractory PTCL, which could have important implications for patient quality of life, Dr. Shustov added.
“The fact that you can take a pill at home, and don’t have to be in clinic once a week, or have the port device, or be infused every week would be an incredible change in quality of life,” he said, “and this is really amplified in the older population where quality of life is so important.”
Duvelisib was FDA approved in 2018, at a dose of 25 mg orally twice daily, for the treatment of chronic lymphocytic leukemia/small lymphocytic lymphoma, and follicular lymphoma, following at least two previous treatments.
In relapsed/refractory PTCL, results of a phase 1 study previously published in Blood showed that duvelisib demonstrated an ORR of 50%, or 8 out of 16 patients treated with 25 or 75 mg twice daily continuously.
The phase 2 study described by Dr. Pro at this year’s ASH meeting included 33 patients with relapsed/refractory PTCL treated with duvelisib 25 mg or 75 mg twice daily as part of a dose-optimization phase, and 25 patients treated in an expansion phase at 75 mg twice daily for two 28-day cycles, followed by treatment at 25 mg twice daily.
Starting at the higher dose of 75 mg twice daily is intended to achieve rapid tumor control, while switching to the lower 25-mg twice-daily dose is to maintain long-term control of the disease while mitigating potential for later toxicities, according to the published abstract for the PRIMO trial.
Results of the dose-optimization phase included an ORR by independent review committee of 62% for patients treated at the 75-mg twice-daily dose, and 40% for those treated at 25 mg twice daily. The median duration of response in the 75-mg twice-daily group was 12.2 months, which Dr. Pro said was significantly higher than what was observed for the lower dose.
In the ongoing dose-expansion phase, the ORR by investigator was 52% (13 of 25 patients), with a CR rate of 36% (9 of 25 patients). The reported data show that with a median duration of follow-up of 3.78 months, the median duration of response thus far is 4.1 months.
The most common grade 3 or higher adverse events were increases in ALT and AST, seen in 24% and 20% of patients, respectively. The most common grade 3 or greater hematologic toxicity was decreased lymphocyte count, seen in 16%.
Three serious treatment-emergent adverse events thought to be related to duvelisib occurred in two patients, including grade 5 pneumonitis in one patient, and skin lesion plus posttransplant lymphoproliferative disorder in the other patient, according to Dr. Pro. Serious treatment-emergent adverse events leading to duvelisib discontinuation included increased ALT/AST in 2 patients and pneumonitis in one patient.
Grade 1-2 adverse events reported at ASH included hypertension, nausea, anemia, fatigue, diarrhea, constipation and pyrexia, among others.
Enrollment in the dose-expansion phase of PRIMO is ongoing and should be complete in February, according to Dr. Pro.
Support for the study came from Verastem Oncology and Secura Bio. Dr. Pro reported research funding from Verastem Oncology, Takeda, and other pharmaceutical companies and honoraria from Takeda and Seattle Genetics.

Results of the dose-optimization phase included an ORR by independent review committee of 62% for patients treated at the 75-mg twice-daily dose, and 40% for those treated at 25 mg twice daily. The median duration of response in the 75-mg twice-daily group was 12.2 months, which Dr. Pro said was significantly higher than what was observed for the lower dose.
In the ongoing dose-expansion phase, the ORR by investigator was 52% (13 of 25 patients), with a CR rate of 36% (9 of 25 patients). The reported data show that with a median duration of follow-up of 3.78 months, the median duration of response thus far is 4.1 months.
The most common grade 3 or higher adverse events were increases in ALT and AST, seen in 24% and 20% of patients, respectively. The most common grade 3 or greater hematologic toxicity was decreased lymphocyte count, seen in 16%.
Three serious treatment-emergent adverse events thought to be related to duvelisib occurred in two patients, including grade 5 pneumonitis in one patient, and skin lesion plus posttransplant lymphoproliferative disorder in the other patient, according to Dr. Pro. Serious treatment-emergent adverse events leading to duvelisib discontinuation included increased ALT/AST in 2 patients and pneumonitis in one patient.
Grade 1-2 adverse events reported at ASH included hypertension, nausea, anemia, fatigue, diarrhea, constipation and pyrexia, among others.
Enrollment in the dose-expansion phase of PRIMO is ongoing and should be complete in February, according to Dr. Pro.
Support for the study came from Verastem Oncology and Secura Bio. Dr. Pro reported research funding from Verastem Oncology, Takeda, and other pharmaceutical companies and honoraria from Takeda and Seattle Genetics.

Duvelisib is demonstrating encouraging activity and manageable toxicities among patients with relapsed/refractory peripheral T-cell lymphoma (PTCL) in a phase 2 trial, an investigator said.
The overall response rate in the dose-optimization phase of the PRIMO trial was more than 60% among patients receiving 75 mg of duvelisib twice daily, with a median duration of response exceeding 12 months, said investigator Barbara Pro, MD, of Northwestern University, Chicago.
In the ongoing dose-expansion phase, in which patients start on 75 mg twice daily and then transition to a lower dose, the ORR is over 50%, including complete responses (CRs) in about one-third of patients, Dr. Pro reported at the annual meeting of the American Society of Hematology.
Most previously approved treatments for relapsed/refractory PTCL are associated with ORRs of less than 30%, low rates of CR, and median progression-free survival of less than 4 months, Dr. Pro said in her presentation.
There have been no unexpected toxicities in the dose-expansion phase, and the adverse event profile is consistent with what has been observed previously for this oral phosphatidylinositol 3-kinase (PI3K) inhibitor, according to Dr. Pro.
Based on results to date, Dr. Pro said she and coinvestigators are hopeful that duvelisib will have a place in the treatment armamentarium for relapsed/refractory PTCL in the future.
“This is one of the most effective agents in T-cell lymphoma, and hopefully will be approved and available for treatment soon,” she said in remarks following her presentation of PRIMO study data.
“The next question would be how to try to move this agent up front,” she added. “We’ll have to try to see what could be the possible combinations and evaluate the possible overlapping toxicity with alternative treatments.”
The PRIMO trial provides “very exciting numbers” that include roughly half of relapsed/refractory PTCL patients are responding to the oral therapy, said Andrei R. Shustov, MD, professor of medicine in the division of hematology at the University of Washington, Seattle.
Perhaps more importantly, at least half of those responses have been CRs, Dr. Shustov noted in an interview: “We haven’t seen this yet in T-cell lymphomas, short of brentuximab vedotin targeting CD30,” he said, referring to the 2018 Food and Drug Administration approval of brentuximab vedotin for previously untreated CD30-expressing PTCL.
If duvelisib is approved, it would be the first oral agent with an indication for relapsed/refractory PTCL, which could have important implications for patient quality of life, Dr. Shustov added.
“The fact that you can take a pill at home, and don’t have to be in clinic once a week, or have the port device, or be infused every week would be an incredible change in quality of life,” he said, “and this is really amplified in the older population where quality of life is so important.”
Duvelisib was FDA approved in 2018, at a dose of 25 mg orally twice daily, for the treatment of chronic lymphocytic leukemia/small lymphocytic lymphoma, and follicular lymphoma, following at least two previous treatments.
In relapsed/refractory PTCL, results of a phase 1 study previously published in Blood showed that duvelisib demonstrated an ORR of 50%, or 8 out of 16 patients treated with 25 or 75 mg twice daily continuously.
The phase 2 study described by Dr. Pro at this year’s ASH meeting included 33 patients with relapsed/refractory PTCL treated with duvelisib 25 mg or 75 mg twice daily as part of a dose-optimization phase, and 25 patients treated in an expansion phase at 75 mg twice daily for two 28-day cycles, followed by treatment at 25 mg twice daily.

NHS England starts pilot trial of blood test for many cancers
“Early detection, particularly for hard-to-treat conditions like ovarian and pancreatic cancer, has the potential to save many lives,” said NHS Chief Executive Sir Simon Stevens in a statement.
The pilot trial will use the Galleri blood test, developed by Grail. Sir Stevens described the blood test as “promising” and said it could “be a game changer in cancer care, helping thousands more people to get successful treatment.”
However, some clinicians have expressed concerns over the potential for false-positive results with the test.
Results of a study of the Galleri blood test, published earlier this year, showed that the test detected 50 types of cancer with a specificity of 99.3% and a false positive rate of 0.7%.
It also correctly identified the originating tissue in 90% of cases. However, the sensitivity was lower, at 67%, for the 12 most common cancers, as reported at the time.
The senior author of that study, Michael Seiden, MD, PhD, president of the U.S. Oncology Network, The Woodlands, Tex., noted that it was not a screening study: the test had been used in patients with cancer and in healthy volunteers. He said the test “is intended to be complementary to, and not replace, existing guideline-recommended screening tests and might provide new avenues of investigation for cancers that don’t currently have screening tests.”
The Galleri test uses next-generation sequencing to analyze the arrangement of methyl groups on circulating cell-free DNA in a blood sample.
Several other blood tests for cancer are under development, including the CancerSEEK test, which has been reported to be able to identify eight common cancers. It measures circulating tumor DNA from 16 genes and eight protein biomarkers and then uses machine learning to analyze the data.
Improving early detection rates
The pilot trial of the blood test is due to start in mid-2021 and will involve 165,000 people.
The trial will include 140,000 individuals aged 50-79 years who were identified through their health records and who have no cancer symptoms. They will undergo blood tests annually for 3 years and will be referred for investigation if a test result is positive.
A second group will include 25,000 people with potential cancer symptoms. These patients will be offered the blood test to speed up their diagnosis after referral to a hospital via the normal channels.
The results of the pilot are expected in 2023. If successful, the test will be rolled out to 1 million individuals from 2024 to 2025.
The pilot trial is part of the NHS Long Term Plan, which aims to increase early detection of cancer. At present, around half of cancers in England are diagnosed in stage I or II; the NHS aims to increase this to 75% by 2028.
“The NHS has set itself an ambitious target,” commented Peter Johnson, MD, PhD, national clinical director for cancer at NHS England and Improvement.
“Tests like this may help us get there far faster, and I am excited to see how this cutting-edge technology will work out as we test it in clinics across the NHS,” he added.
Lord David Prior, chair of NHS England, noted that almost 200,000 people die from cancer in the United Kingdom every year and that “many of these people are diagnosed too late for treatment to be effective.
“This collaboration between the NHS and Grail offers the chance for a wide range of cancers to be diagnosed much earlier and could fundamentally change the outlook for people with cancer,” he said.
However, some clinicians raised potential concerns.
Stephen Duffy, PhD, Center for Cancer Prevention, Queen Mary University of London, described the pilot as “very exciting,” but cautioned: “We will need to find out just how early the test detects cancers and whether it can it be used in a way which minimizes anxiety from false positives.”
Yong-Jie Lu, MD, PhD, also at Queen Mary University of London, said: “It is not clear how early it aims to catch cancer. For a cancer screen test, it needs very high specificity (>99%), otherwise it may end up in a similar situation as the PSA [prostate-specific antigen] test for prostate cancer, or even worse.”
Mangesh Thorat, MD, Cancer Prevention Trials Unit, King’s College London, warned: “It is likely that for every testing round ... there will be about 1,000 false-positive results, and the test may not be able to pinpoint the location of cancer in 3%-4% of those with a true positive result, necessitating a range of imaging and other investigations in these participants.”
No funding for the study has been declared. The investigators have disclosed no relevant financial relationships.

Childhood Hodgkin survivors have neurocognitive impairment
More than 2 decades on, adult survivors of childhood Hodgkin lymphoma report significantly more neurocognitive impairment than their siblings, but the differences may be related to risk factors in adulthood rather than to treatment in childhood, investigators say.
Among adults with a history of childhood Hodgkin lymphoma and their siblings as controls, the survivors reported significantly worse functioning than their brothers or sisters in four domains of neurocognitive functioning.
In multivariate analysis, however, while sex, race, activity level and smoking status were all significant predictors for worse neurocognitive impairment, there were no significant associations between chemotherapy drugs or chest radiation and neurocognitive impairment, said Annalynn M. Williams, PhD, from St. Jude Children’s Research Hospital in Memphis.
“Hodgkin lymphoma is the most common cancer diagnosed in adolescents, and for many years we’ve had high cure rates, resulting in a growing population of survivors who are now, unfortunately, at an increased risk for cardiovascular, respiratory, endocrine and neurologic late morbidity. The neurocognitive morbidity in this population, however, is unknown,” she said in oral abstract presented at the annual meeting of the American Society of Hematology.
Survivors and sibs
To better characterize the potential late neurocognitive effects of intensive Hodgkin lymphoma therapy in childhood, Dr. Williams and colleagues polled survivors of childhood Hodgkin lymphoma and randomly selected sibling controls who were participants in the Childhood Cancer Survivor Study (CCSS).
Participants were asked to complete questionnaires regarding four domains of neurocognitive impairment: task efficiency, emotional regulation, organization, and memory. The investigators defined impairment in each domain as a score lower than that of the 90th percentile of community controls from the St. Jude Lifetime Cohort.
A total of 1,564 survivors and 725 controls completed the questionnaires and were included in the study.
The median age at follow-up was slightly higher among survivors, at 37 versus 32 years. The median age at diagnosis was 14, and the median time since diagnosis was 23 years.
In all, 10.8% of survivors reported impaired task efficiency, compared with 7.7% of controls. Problems with emotional regulation were reported by 16.6% of survivors versus 11.5% of siblings, and difficulties with organization and memory were reported by 12.1% versus10.3%, and 8.1% versus 5.7%, respectively.
In a model adjusted for age, sex, and race, the relative risks for neurocognitive impairment among survivors versus siblings, were as follows: task efficiency (RR,1.37); emotional regulation (RR, 1.56); organization (RR, 1.32); memory (RR, 1.72) (all significant by confidence interval).
In a model adjusted for sex, race, smoking status, exercise, age, time since diagnosis, and treatment exposures, risk factors for neurocognitive impairment among survivors included female versus male sex (significant for emotional regulation and memory deficits); non-White versus White (significant for task efficiency); former smoker versus never (significant for all domains except organization); current smoker versus never (significant for task efficiency and emotional regulation); and meeting Centers for Disease Control and Prevention exercise criteria versus not (negatively significant for task efficiency and organization); (P < .05 for all above comparisons).
However, in a model adjusted for relapse, second malignancy, treatment exposures, age, sex, race, time since diagnosis, smoking status and physical activity, only relapse or second malignancy – surrogates for additional treatment exposures – were significantly associated with neurocognitive impairment, and then only in the domain of task efficiency.
Chronic conditions significantly associated with risk for impairment included cardiovascular disease (significant across all domains), respiratory comorbidities (significant for task efficiency), endocrine disorders (significant for task efficiency), and neurologic disorders (significant in all domains except organization).
“While these analyses give us a sense of the presence of neurocognitive impairment in a large sample of Hodgkin lymphoma survivors from across the U.S., these analyses are limited by the self-reported nature of the data,” Dr. Williams acknowledged.
“Because survivors self-report impairments, these likely represent overt, symptomatic neurocognitive impairments. Many more survivors may experience more subtle neurocognitive impairments, and additional research with objective measures of both chronic health conditions and neurocognitive functioning are warranted,” she added.
Smoking gun?
In the question-and-answer session following the presentation, session comoderator Pallawi Torka, MD, from Roswell Park Comprehensive Cancer Center in Buffalo, N.Y., who was not involved in the research, commented that the finding regarding a link between current and former smoking as risk factors for neurocognitive impairment was “intriguing.”
“Do you think that smoking is a cause or an effect of having that impairment in childhood survivors of Hodgkin lymphoma?” she asked.
“That’s a great question, and actually one we have spent a great deal of time discussing, and we’re still trying to tease that apart. We’re still not really sure where that association is coming from,” Dr. Williams replied.
She noted that, in a different sample of CCSS participants from whom biospecimens were collected, the investigators plan to see whether smoking drives inflammation and oxidative stress mechanisms that may be contributing to neurocognitive impairment, or whether smoking is a coping mechanism related to anxiety and depression, which have also been seen in survivors.
Kara Kelly, MD, a pediatric oncologist at Roswell Park, commented that some survivors report symptoms of cognitive dysfunction shortly after treatment, and asked whether there might be a relationship to Hodgkin-specific factors such as B symptoms, in which cytokine-mediated inflammation may play a role.
Dr. Williams said that, “unfortunately, in CCSS these survivors had to be at least 5 years from diagnosis, but in many cases were recruited years after their diagnosis and treatment, so we don’t have data on B symptoms.”
The CCSS is funded by the National Cancer Institute. Dr. Williams, Dr. Palawi, and Dr. Kelly all reported no relevant conflicts of interest to disclose.

The investigators defined impairment in each domain as a score lower than that of the 90th percentile of community controls from the St. Jude Lifetime Cohort.
A total of 1,564 survivors and 725 controls completed the questionnaires and were included in the study.
The median age at follow-up was slightly higher among survivors, at 37 versus 32 years. The median age at diagnosis was 14, and the median time since diagnosis was 23 years.
In all, 10.8% of survivors reported impaired task efficiency, compared with 7.7% of controls. Problems with emotional regulation were reported by 16.6% of survivors versus 11.5% of siblings, and difficulties with organization and memory were reported by 12.1% versus10.3%, and 8.1% versus 5.7%, respectively.
In a model adjusted for age, sex, and race, the relative risks for neurocognitive impairment among survivors versus siblings, were as follows: task efficiency (RR,1.37); emotional regulation (RR, 1.56); organization (RR, 1.32); memory (RR, 1.72) (all significant by confidence interval).
In a model adjusted for sex, race, smoking status, exercise, age, time since diagnosis, and treatment exposures, risk factors for neurocognitive impairment among survivors included female versus male sex (significant for emotional regulation and memory deficits); non-White versus White (significant for task efficiency); former smoker versus never (significant for all domains except organization); current smoker versus never (significant for task efficiency and emotional regulation); and meeting Centers for Disease Control and Prevention exercise criteria versus not (negatively significant for task efficiency and organization); (P < .05 for all above comparisons).
However, in a model adjusted for relapse, second malignancy, treatment exposures, age, sex, race, time since diagnosis, smoking status and physical activity, only relapse or second malignancy – surrogates for additional treatment exposures – were significantly associated with neurocognitive impairment, and then only in the domain of task efficiency.
Chronic conditions significantly associated with risk for impairment included cardiovascular disease (significant across all domains), respiratory comorbidities (significant for task efficiency), endocrine disorders (significant for task efficiency), and neurologic disorders (significant in all domains except organization).
“While these analyses give us a sense of the presence of neurocognitive impairment in a large sample of Hodgkin lymphoma survivors from across the U.S., these analyses are limited by the self-reported nature of the data,” Dr. Williams acknowledged.
“Because survivors self-report impairments, these likely represent overt, symptomatic neurocognitive impairments. Many more survivors may experience more subtle neurocognitive impairments, and additional research with objective measures of both chronic health conditions and neurocognitive functioning are warranted,” she added.
Smoking gun?
In the question-and-answer session following the presentation, session comoderator Pallawi Torka, MD, from Roswell Park Comprehensive Cancer Center in Buffalo, N.Y., who was not involved in the research, commented that the finding regarding a link between current and former smoking as risk factors for neurocognitive impairment was “intriguing.”
“Do you think that smoking is a cause or an effect of having that impairment in childhood survivors of Hodgkin lymphoma?” she asked.
“That’s a great question, and actually one we have spent a great deal of time discussing, and we’re still trying to tease that apart. We’re still not really sure where that association is coming from,” Dr. Williams replied.
She noted that, in a different sample of CCSS participants from whom biospecimens were collected, the investigators plan to see whether smoking drives inflammation and oxidative stress mechanisms that may be contributing to neurocognitive impairment, or whether smoking is a coping mechanism related to anxiety and depression, which have also been seen in survivors.
Kara Kelly, MD, a pediatric oncologist at Roswell Park, commented that some survivors report symptoms of cognitive dysfunction shortly after treatment, and asked whether there might be a relationship to Hodgkin-specific factors such as B symptoms, in which cytokine-mediated inflammation may play a role.
Dr. Williams said that, “unfortunately, in CCSS these survivors had to be at least 5 years from diagnosis, but in many cases were recruited years after their diagnosis and treatment, so we don’t have data on B symptoms.”
The CCSS is funded by the National Cancer Institute. Dr. Williams, Dr. Palawi, and Dr. Kelly all reported no relevant conflicts of interest to disclose.

Durable responses with anti-BCMA CAR T-cell for multiple myeloma
For patients with heavily-pretreated multiple myeloma, the early and deep responses seen with the novel chimeric antigen receptor T-cell (CAR T-cell) construct ciltacabtagene autoleucel (cilta-cel) have also been durable, according to investigators in the CARTITUDE-1 trial.
Among 97 patients with multiple myeloma that had progressed on three or more prior lines of therapy or following treatment with at least two lines of therapy with a proteasome inhibitor and immunomodulating agent, the overall response rate (ORR) was 96.9%, with a median duration of response not reached after a median of 12.4 months of follow-up, reported Deepu Madduri, MD of Mount Sinai Medical Center in New York, and colleagues.
“We saw how heavily pretreated these patients were, and to see a one-time treatment get these kind of response rates is quite exceptional. What’s even more impressive is that 72% of these patients were still maintaining their response at the time of data cutoff,“ she said in an oral abstract presented during the virtual American Society of Hematology annual meeting.
Cilta-cel is a second-generation CAR T containing two single-domain antibodies targeted against B-cell maturation protein (BCMA). BCMA was first described in myeloma in 2004 as a mechanism for the growth and survival of malignant plasma cells.
As previously reported, the same CAR T-cell construct showed a high overall response with manageable toxicities in 74 patients with relapsed/refractory multiple myeloma.
Ciltacabtagene autoleucel was granted a breakthrough therapy designation for relapsed/refractory multiple myeloma by the Food and Drug Administration in December 2019, a priority medicines (PRIME) designation by the European Medicines Agency in April 2019, and breakthrough designation in China in September 2020.
At the 2019 ASH annual meeting, Dr. Madduri reported phase 1b results from the trial, which showed that for 29 patients with heavily pretreated, relapsed/refractory multiple myeloma, the ORR at 6 months median follow-up was 100%, including 69% complete responses, with 27 patients remaining free of disease progression.
Combined data
For the 2020 ASH annual meeting, Dr. Madduri reported combined results from phases 1b and 2 of the CARTITUDE-1 study.
The investigators enrolled patients with multiple myeloma with measurable diseases as assessed by M-protein or serum free light chain levels who had experienced disease progression on at least three prior lines of therapy, or whose disease was refractory to at least two lines of therapy with a proteasome inhibitor, immunomodulatory drug, and an anti-CD38 antibody.
Patients underwent apheresis for T-cell collection, with bridging therapy allowed until the expanded T cells could be delivered.
Following T-cell depletion with cyclophosphamide 300 mg/m2 and fludarabine 30 mg/m2 over 3 days, patients received a single weight-based infusion (compared with fixed-dose infusions used with other CAR T-cell constructs).
The dose was targeted at 0.75x106 CAR-positive cells/kg, with a target range of 0.5–1.0x106, administered 5-7 days after the start of the conditioning regimen.
Of the 101 patients who underwent lymphodepletion, 97 (29 in phase 1b and 68 in phase 2) were treated with cilta-cel. Five of the patients in phase 1b and nine in phase 2 died on study, five of whom succumbed to progressive disease, and three due to adverse events unrelated to treatment. The remaining six patients died from treatment-related causes, including two patients from sepsis or septic shock, and one each from the cytokine release syndrome (CRS)/hemophagocytic lymphohistiocytosis (HLH), lung abscess, respiratory failure, and neurotoxicity.
At the time of data cutoff, 83 patients remained on study.
High ORR
The ORR was 96.9% (94 of 97 patients), comprising 67% stringent complete responses (sCR), 25.8% very good partial responses (VGPR), and 4.1% partial responses (PR).
Among 57 patients evaluable for minimal residual disease (MRD), 53 (93%) were MRD negative. Of this group, 49 had a VGPR or better.
The median time to first response was 1 month (range 0.9 to 8.5 months). At the time of data cutoff 70 patients had an ongoing response.
Among patients followed for a minimum of 6 months, most had cilta-cel CAR T-cells below the level of quantification (2 cells per microliter) in peripheral blood.
At a median follow-up of 12.4 months, 12-month overall progression-free survival rate was 76%, with the median PFS not reached. The 12-month overall survival rate was 88.5%, with the median OS not reached.
Safety data
All patients had at least one hematologic adverse event, 96 of which were grade 3 or 4 in severity. The events include neutropenia, anemia, thrombocytopenia, leukopenia, and lymphopenia. The median time to recovery was 2 weeks for grade 3 or 4 neutropenia and 4 weeks for thrombocytopenia.
Infections of any grade occurred in 57.7% of patients, including grade 3/4 pneumonia in 8.2% and grade 3/4 sepsis in 4.1%.
Grade 3 or 4 nonhematologic toxicities were uncommon, Dr. Madduri noted.
CRS of any grade occurred in 92 patients, but only 4 had grade 3 or 4 CRS.
Neurotoxicities occurred in 20 patients, of whom 10 had grade 3 or 4 neurotoxicity.
Immune effector cell-associated neurotoxicity syndrome (ICANS) occurred in 16 patients, with 2 having grade 3 or greater ICANS. Other neurotoxicities of any grade, many which overlapped with ICANS, occurred in 12 patients, with 9 having grade 3 or 4 neurotoxicity.
The median time to ICANS onset was 8 days, with a median time to recovery of 4 days. Other neurotoxicities took longer to manifest and disappear, however, with a median time to onset of 27 days, and median time to recovery of 75 days.
Neurotoxicity mechanism questioned
In the question-and-answer session following her presentation, an audience member asked whether the investigators had any insights into the mechanism underlying the non-ICANS neurotoxicities they saw.
“We saw no clear etiology in the other neurotoxicities, but we saw that maybe there could be some mild associations with high tumor burden, prior CRS, ICANS, or even the higher expansion and persistence of these cells,” Dr. Madduri replied.
She noted that subsequent to these findings, the investigators have implemented mitigation strategies including allowing patients to have more bridging chemotherapy, more aggressive steroid use for early ICANS, and extensive monitoring.
Eric Smith, MD, PhD, of Memorial Sloan Kettering Cancer Center in New York, said that the non-ICANS neurotoxicity profile of cilta-cel was different from that seen in other CAR T-cell trials, and asked how it compared to that of bi-specific BCMA/CD3 CAR T constructs.
“We did see some nerve palsies and peripheral motor neuropathy, but it wasn’t that many patients, and it’s really hard to compare what happened here with the bi-specifics, as every product is very different,” she said.
The study was sponsored by Janssen Research & Development and Legend Biotech. Dr. Madduri disclosed honoraria, consultancy, and speakers bureau activities for those companies and others.

Allogeneic transplant leads to durable remissions in T-cell lymphomas
, results of a large retrospective observational study suggest.
Five-year progression-free survival (PFS) approached 40% and 5-year overall survival (OS) was over 50% in the study, which according to an investigator is the largest-ever reported patient series of allogeneic stem cell transplantation in T-cell lymphomas.
“We believe that eligible patients with relapsed/refractory T-cell lymphomas should be considered for consultation for allogeneic transplant by an expert clinician,” said investigator Neha Mehta-Shah, MD, of Washington University in St. Louis.
“These decisions should occur on a patient by patient level – but it’s important to consider this,” Dr. Mehta-Shah said at the annual meeting of the American Society of Hematology, held virtually this year.
Notably, patients with cutaneous T-cell lymphoma (CTCL) had a higher rate of relapse yet similar overall survival (OS) compared to patients with common peripheral T-cell lymphoma (PTCL) subtypes, according to Dr. Mehta-Shah.
Among PTCL subtypes, there was a trend toward improved PFS and OS for angioimmunoblastic T-cell lymphoma (AITL), compared with PTCL not otherwise specified (PTCL-NOS) and anaplastic large-cell lymphoma (ALCL), she added.
Catherine M. Diefenbach, MD, director of the clinical lymphoma program at NYU Langone’s Perlmutter Cancer Center, said the results of this retrospective study need to considered in light of the treatment-related risks associated with allogeneic transplantation.
Treatment-related mortality in the study ranged from about 8% to 24%, depending on the donor type, while acute and chronic graft-versus-host-disease (GvHD) was seen in more than 40% of patients, the reported data show.
“If I have a relapsed patient with AITL, I would look to this data and say that patients with AITL appear in a retrospective study to have a strong benefit,” Dr. Diefenbach said in an interview.
“For the other patients, you would describe both potential benefits and also discuss the treatment-associated risks – both the chronic GvHD and transplant-related mortality – and you’d have to balance the risk with the benefits for each individual case,” Dr. Diefenbach added.
The retrospective analysis by Dr. Mehta-Shah and colleagues included 508 consecutive T-cell lymphoma patients receiving allogeneic transplants at 12 academic centers between 2000 and 2019. The most common subtypes were PTCL-NOS in 26%, AITL in 16%, CTCL in 13%, and hepatosplenic T-cell lymphoma (HSTCL) in 7%. About 40% had a matched related donor (MRD) and 39% had a matched unrelated donor (MUD). The conditioning regimen was myeloablative in about a third of patients and nonmyeloablative in two-thirds.
At 5 years, PFS was 39.4% and OS was 50.8% for the overall study cohort, Dr. Mehta-Shah reported, noting that the median time from relapse to death post allogeneic transplant was 10.2 months.
Patients in complete remission at the time of transplant fared better than others, with a median PFS of 44.6 months vs. 8.5 months for those in partial remission, 21.0 months in those with stable disease, and 3.5 months for those with progressive disease at time of transplant, data show.
Patients with common PTCL subtypes had better PFS compared to patients with CTCL, yet OS was similar, according to the investigator. At 5 years, PFS was 43.7% and 18.6%, respectively, for PTCL and CTCL, while OS was 53.1% and 44.0%, respectively.
There was a trend toward improved outcomes for AITL relative to PTCL-NOS and ALCL, with a median PFS of 51.4 months for AITL versus 18.3 months those other subtypes. Similarly, median OS was not reached for AITL versus 73.1 months in the other subtypes.
Treatment-related mortality was lowest for patients with MRDs, or 8.2% at 12 months, Dr. Mehta-Shah reported, while patients with MUDs, mismatched donors, or haploidentical donors had treatment-related mortality of 13% to 16% at 12 months, and those with cord blood donors had treatment-related mortality of nearly 24% at 12 months.
Acute GvHD was observed in 46% of patients and chronic GvHD was seen in nearly 41%, the investigator added.
While these findings are important to consider in individual patient consultations, the study is nevertheless subject to limitations including patient selection and referral bias, according to Dr. Mehta-Shah.
“This was a retrospective analysis of patients who underwent transplant,” she said in a question-and-answer period. “Of course, that is heavily biased by who got to a transplant center, who was well enough to achieve transplant, and who had a donor or donor options, as well as their overall health and depth of remission,” the researcher said.
“I think this just represents what we could tell patients about what may happen to them once they embark on a transplant,” she added, “but really, there would be more prospective work needed to be done for what happens to patients overarching, and how many of them even get to a transplant consultation.”
Further studies should be done to develop predictive tools or biomarkers to determine who benefits from an allogeneic transplant, if there are predictors of relapse following allogeneic transplant, and what are the mechanisms of relapse following allogeneic transplant, according to Dr. Mehta-Shah.
Dr. Mehta-Shah reported research funding from Bristol Myers-Squibb, Celgene, Verastem, Corvus, Innate Pharmaceuticals, and Genentech/Roche. She reported consultancy with Kyowa Hakko Kirin, C4 Therapeutics, and Karyopharm Therapeutics.

Catherine M. Diefenbach, MD, director of the clinical lymphoma program at NYU Langone’s Perlmutter Cancer Center, said the results of this retrospective study need to considered in light of the treatment-related risks associated with allogeneic transplantation.
Treatment-related mortality in the study ranged from about 8% to 24%, depending on the donor type, while acute and chronic graft-versus-host-disease (GvHD) was seen in more than 40% of patients, the reported data show.
“If I have a relapsed patient with AITL, I would look to this data and say that patients with AITL appear in a retrospective study to have a strong benefit,” Dr. Diefenbach said in an interview.
“For the other patients, you would describe both potential benefits and also discuss the treatment-associated risks – both the chronic GvHD and transplant-related mortality – and you’d have to balance the risk with the benefits for each individual case,” Dr. Diefenbach added.
The retrospective analysis by Dr. Mehta-Shah and colleagues included 508 consecutive T-cell lymphoma patients receiving allogeneic transplants at 12 academic centers between 2000 and 2019. The most common subtypes were PTCL-NOS in 26%, AITL in 16%, CTCL in 13%, and hepatosplenic T-cell lymphoma (HSTCL) in 7%. About 40% had a matched related donor (MRD) and 39% had a matched unrelated donor (MUD). The conditioning regimen was myeloablative in about a third of patients and nonmyeloablative in two-thirds.
At 5 years, PFS was 39.4% and OS was 50.8% for the overall study cohort, Dr. Mehta-Shah reported, noting that the median time from relapse to death post allogeneic transplant was 10.2 months.
Patients in complete remission at the time of transplant fared better than others, with a median PFS of 44.6 months vs. 8.5 months for those in partial remission, 21.0 months in those with stable disease, and 3.5 months for those with progressive disease at time of transplant, data show.
Patients with common PTCL subtypes had better PFS compared to patients with CTCL, yet OS was similar, according to the investigator. At 5 years, PFS was 43.7% and 18.6%, respectively, for PTCL and CTCL, while OS was 53.1% and 44.0%, respectively.
There was a trend toward improved outcomes for AITL relative to PTCL-NOS and ALCL, with a median PFS of 51.4 months for AITL versus 18.3 months those other subtypes. Similarly, median OS was not reached for AITL versus 73.1 months in the other subtypes.
Treatment-related mortality was lowest for patients with MRDs, or 8.2% at 12 months, Dr. Mehta-Shah reported, while patients with MUDs, mismatched donors, or haploidentical donors had treatment-related mortality of 13% to 16% at 12 months, and those with cord blood donors had treatment-related mortality of nearly 24% at 12 months.
Acute GvHD was observed in 46% of patients and chronic GvHD was seen in nearly 41%, the investigator added.
While these findings are important to consider in individual patient consultations, the study is nevertheless subject to limitations including patient selection and referral bias, according to Dr. Mehta-Shah.
“This was a retrospective analysis of patients who underwent transplant,” she said in a question-and-answer period. “Of course, that is heavily biased by who got to a transplant center, who was well enough to achieve transplant, and who had a donor or donor options, as well as their overall health and depth of remission,” the researcher said.
“I think this just represents what we could tell patients about what may happen to them once they embark on a transplant,” she added, “but really, there would be more prospective work needed to be done for what happens to patients overarching, and how many of them even get to a transplant consultation.”
Further studies should be done to develop predictive tools or biomarkers to determine who benefits from an allogeneic transplant, if there are predictors of relapse following allogeneic transplant, and what are the mechanisms of relapse following allogeneic transplant, according to Dr. Mehta-Shah.

, results of a large retrospective observational study suggest.
Five-year progression-free survival (PFS) approached 40% and 5-year overall survival (OS) was over 50% in the study, which according to an investigator is the largest-ever reported patient series of allogeneic stem cell transplantation in T-cell lymphomas.
“We believe that eligible patients with relapsed/refractory T-cell lymphomas should be considered for consultation for allogeneic transplant by an expert clinician,” said investigator Neha Mehta-Shah, MD, of Washington University in St. Louis.
“These decisions should occur on a patient by patient level – but it’s important to consider this,” Dr. Mehta-Shah said at the annual meeting of the American Society of Hematology, held virtually this year.

ZUMA-5: Axi-cel yields high response rate in indolent NHL
phase 2 study results presented at the annual meeting of the American Society of Hematology, held virtually this year.
, according toThe overall response rate exceeded 90% in the ZUMA-5 study, which included patients with multiply relapsed follicular lymphoma (FL) or marginal zone lymphoma (MZL) who were treated with this anti-CD19 chimeric antigen receptor (CAR) T cell therapy.
“Although longer follow-up is needed, these responses appear to be durable,” said investigator Caron Jacobson, MD, of Dana-Farber Cancer Institute in Boston.
Complete responses (CRs) after axi-cel treatment were seen in about three-quarters of patients, and most of those patients were still in response with a median follow-up that approached 1.5 years as of this report at the ASH meeting.
In her presentation, Dr. Jacobson said the safety profile of axi-cel in ZUMA-5 was manageable and “at least similar” to what was previously seen in aggressive relapsed lymphomas, referring to the ZUMA-1 study that led to 2017 approval by the Food and Drug Administration of the treatment for relapsed or refractory large B-cell lymphoma after two or more lines of systemic therapy.
The FL patient cohort in ZUMA-5 appeared to have lower rates of cytokine release syndrome (CRS) and high-grade neurotoxicity, compared with the MZL cohort in the study, she added.
Catherine Bollard, MD, of Children’s National Research Institute in Washington, said these results suggest axi-cel may be a “viable treatment option” for some patients with indolent lymphomas who have not responded to other therapies.
“What the field does need is long-term follow-up in the real-world setting to see what the true progression-free and disease-free survival is for these patients,” said Dr. Bollard, who moderated a media briefing that included the ZUMA-5 study.
“It’s really exciting to see this data in the [indolent] lymphoma setting, and I actually would like to see it moved further up in the treatment of patients, earlier in their disease process, if that’s going to be possible,” she added.
Promising results
The report on ZUMA-5, presented by Dr. Jacobson, involved 146 patients with relapsed/refractory indolent NHL: 124 patients with FL and an exploratory cohort of 22 patients with MZL. All patients had received at least two prior lines of therapy.
Following a fludarabine/cyclophosphamide conditioning regimen, patients received axi-cel at the FDA-approved dose of 2 x 106 CAR-positive T cells per kg of body weight. The primary endpoint of the study was overall response rate (ORR).
For 104 patients evaluable for efficacy, the ORR was 92% (96 patients), including CR in 76% (79 patients), data show. Among 84 FL patients evaluable for efficacy, ORR and CR were 94% (79 patients) and 80% (67 patients), respectively, while among 20 evaluable patients in the exploratory MZL cohort, ORR and CR were 60% (12 patients) and 25% (5 patients), respectively.
Sixty-four percent of patients with FL had an ongoing response at a median follow-up of 17.5 months, according to Dr. Jacobson, who added that median duration of response (DOR) had not been reached, while the 12-month DOR rate approached 72%.
The 12-month progression-free survival and overall survival rates were 73.7% and 92.9%, respectively, with medians not yet reached for either survival outcome, according to reported data.
Adverse effects
The incidence of grade 3 or greater neurologic events was lower in FL patients (15%), compared with MZL patients (41%), according to Dr. Jacobson.
While CRS occurred in 82% of patients, rates of grade 3 or greater CRS occurred in just 6% of FL patients and 9% of MZL patients, the investigator said.
There were no grade 5 neurologic events, and one grade 5 CRS was observed, she noted in her presentation.
The median time to onset of CRS was 4 days, compared with 2 days in the ZUMA-1 trial. “This may have implications for the possibility of outpatient therapy,” she said.
A study is planned to look at outpatient administration of axi-cel in patients with indolent NHL, she added.
Dr. Jacobson said she had no conflicts of interest to declare. Coauthors reported disclosures related to Kite, a Gilead Company; Genentech; Epizyme; Verastem; Novartis; and Pfizer, among others.

Cancer rates on the rise in adolescents and young adults
Rates of cancer increased by 30% from 1973 to 2015 in adolescents and young adults (AYAs) aged 15–39 years in the United States, according to a review of almost a half million cases in the National Institutes of Health’s Surveillance, Epidemiology, and End Results database.
There was an annual increase of 0.537 new cases per 100,000 people, from 57.2 cases per 100,000 in 1973 to 74.2 in 2015.
Kidney carcinoma led with the highest rate increase. There were also marked increases in thyroid and colorectal carcinoma, germ cell and trophoblastic neoplasms, and melanoma, among others.
The report was published online December 1 in JAMA Network Open.
“Clinicians should be on the lookout for these cancers in their adolescent and young adult patients,” said senior investigator Nicholas Zaorsky, MD, an assistant professor of radiation oncology and public health sciences at the Penn State Cancer Institute, Hershey, Pennsylvania.
“Now that there is a better understanding of the types of cancer that are prevalent and rising in this age group, prevention, screening, diagnosis and treatment protocols specifically targeted to this population should be developed,” he said in a press release.
The reasons for the increases are unclear, but environmental and dietary factors, increasing obesity, and changing screening practices are likely in play, the authors comment. In addition, “cancer screening and overdiagnosis are thought to account for much of the increasing rates of thyroid and kidney carcinoma, among others,” they add.
The American Cancer Society (ACS) recently found similar increases in thyroid, kidney, and colorectal cancer among AYAs, as well as an increase in uterine cancer.
It’s important to note, however, that “this phenomenon is largely driven by trends for thyroid cancer, which is thought to be a result of overdiagnosis,” said ACS surveillance researcher Kimberly Miller, MPH, when asked to comment on the new study.
“As such, it is extremely important to also consider trends in cancer mortality rates among this age group, which are declining overall but are increasing for colorectal and uterine cancers. The fact that both incidence and mortality rates are increasing for these two cancers suggests a true increase in disease burden and certainly requires further attention and research,” she said.
Historically, management of cancer in AYAs has fallen somewhere between pediatric and adult oncology, neither of which capture the distinct biological, social, and economic needs of AYAs. Research has also focused on childhood and adult cancers, leaving cancer in AYAs inadequately studied.
The new findings are “valuable to guide more targeted research and interventions specifically to AYAs,” Zaorsky and colleagues say in their report.
Among female patients ― 59.1% of the study population ― incidence increased for 15 cancers, including kidney carcinoma (annual percent change [APC], 3.632), thyroid carcinoma (APC, 3.456), and myeloma, mast cell, and miscellaneous lymphoreticular neoplasms not otherwise specified (APC, 2.805). Rates of five cancers declined, led by astrocytoma not otherwise specified (APC, –3.369) and carcinoma of the gonads (APC, –1.743).
Among male patients, incidence increased for 14 cancers, including kidney carcinoma (APC, 3.572), unspecified soft tissue sarcoma (APC 2.543), and thyroid carcinoma (APC, 2.273). Incidence fell for seven, led by astrocytoma not otherwise specified (APC, –3.759) and carcinoma of the trachea, bronchus, and lung (APC, –2.635).
Increased testicular cancer rates (APC, 1.246) could be related to greater prenatal exposure to estrogen and progesterone or through dairy consumption; increasing survival of premature infants; and greater exposure to cannabis, among other possibilities, the investigators say.
Increases in colorectal cancer might be related to fewer vegetables and more fat and processed meat in the diet; lack of exercise; and increasing obesity. Human papillomavirus infection has also been implicated.
Higher rates of melanoma could be related to tanning bed use.
Declines in some cancers could be related to greater use of oral contraceptives; laws reducing exposure to benzene and other chemicals; and fewer people smoking.
Although kidney carcinoma has increased at the greatest rate, it’s uncommon. Colorectal and thyroid carcinoma, melanoma, non-Hodgkin lymphoma, and germ cell and trophoblastic neoplasms of the gonads contribute more to the overall increase in cancers among AYAs, the investigators note.
Almost 80% of the patients were White; 10.3% were Black.
The study was funded by the National Center for Advancing Translational Sciences. The investigators have disclosed no relevant financial relationships.

There was an annual increase of 0.537 new cases per 100,000 people, from 57.2 cases per 100,000 in 1973 to 74.2 in 2015.
Kidney carcinoma led with the highest rate increase. There were also marked increases in thyroid and colorectal carcinoma, germ cell and trophoblastic neoplasms, and melanoma, among others.
The report was published online December 1 in JAMA Network Open.
“Clinicians should be on the lookout for these cancers in their adolescent and young adult patients,” said senior investigator Nicholas Zaorsky, MD, an assistant professor of radiation oncology and public health sciences at the Penn State Cancer Institute, Hershey, Pennsylvania.
“Now that there is a better understanding of the types of cancer that are prevalent and rising in this age group, prevention, screening, diagnosis and treatment protocols specifically targeted to this population should be developed,” he said in a press release.
The reasons for the increases are unclear, but environmental and dietary factors, increasing obesity, and changing screening practices are likely in play, the authors comment. In addition, “cancer screening and overdiagnosis are thought to account for much of the increasing rates of thyroid and kidney carcinoma, among others,” they add.
The American Cancer Society (ACS) recently found similar increases in thyroid, kidney, and colorectal cancer among AYAs, as well as an increase in uterine cancer.
It’s important to note, however, that “this phenomenon is largely driven by trends for thyroid cancer, which is thought to be a result of overdiagnosis,” said ACS surveillance researcher Kimberly Miller, MPH, when asked to comment on the new study.
“As such, it is extremely important to also consider trends in cancer mortality rates among this age group, which are declining overall but are increasing for colorectal and uterine cancers. The fact that both incidence and mortality rates are increasing for these two cancers suggests a true increase in disease burden and certainly requires further attention and research,” she said.
Historically, management of cancer in AYAs has fallen somewhere between pediatric and adult oncology, neither of which capture the distinct biological, social, and economic needs of AYAs. Research has also focused on childhood and adult cancers, leaving cancer in AYAs inadequately studied.
The new findings are “valuable to guide more targeted research and interventions specifically to AYAs,” Zaorsky and colleagues say in their report.
Among female patients ― 59.1% of the study population ― incidence increased for 15 cancers, including kidney carcinoma (annual percent change [APC], 3.632), thyroid carcinoma (APC, 3.456), and myeloma, mast cell, and miscellaneous lymphoreticular neoplasms not otherwise specified (APC, 2.805). Rates of five cancers declined, led by astrocytoma not otherwise specified (APC, –3.369) and carcinoma of the gonads (APC, –1.743).
Among male patients, incidence increased for 14 cancers, including kidney carcinoma (APC, 3.572), unspecified soft tissue sarcoma (APC 2.543), and thyroid carcinoma (APC, 2.273). Incidence fell for seven, led by astrocytoma not otherwise specified (APC, –3.759) and carcinoma of the trachea, bronchus, and lung (APC, –2.635).
Increased testicular cancer rates (APC, 1.246) could be related to greater prenatal exposure to estrogen and progesterone or through dairy consumption; increasing survival of premature infants; and greater exposure to cannabis, among other possibilities, the investigators say.
Increases in colorectal cancer might be related to fewer vegetables and more fat and processed meat in the diet; lack of exercise; and increasing obesity. Human papillomavirus infection has also been implicated.
Higher rates of melanoma could be related to tanning bed use.
Declines in some cancers could be related to greater use of oral contraceptives; laws reducing exposure to benzene and other chemicals; and fewer people smoking.
Although kidney carcinoma has increased at the greatest rate, it’s uncommon. Colorectal and thyroid carcinoma, melanoma, non-Hodgkin lymphoma, and germ cell and trophoblastic neoplasms of the gonads contribute more to the overall increase in cancers among AYAs, the investigators note.
Almost 80% of the patients were White; 10.3% were Black.
The study was funded by the National Center for Advancing Translational Sciences. The investigators have disclosed no relevant financial relationships.

Immune checkpoint inhibitors don’t increase COVID-19 incidence or mortality, studies suggest
Cytokine storm plays a major role in the pathogenesis of COVID-19, according to research published in The Lancet Respiratory Medicine. This has generated concern about using ICIs during the pandemic, given their immunostimulatory activity and the risk of immune-related adverse effects.
However, two retrospective studies suggest ICIs do not increase the risk of developing COVID-19 or dying from the disease.
In a study of 1,545 cancer patients prescribed ICIs and 20,418 matched controls, the incidence of COVID-19 was 1.4% with ICI therapy and 1.0% without it (odds ratio, 1.38; P = .15).
In a case-control study of 50 patients with cancer and COVID-19, 28% of patients who had received ICIs died from COVID-19, compared with 36% of patients who had not received ICIs (OR, 0.36; P = .23).
Vartan Pahalyants and Kevin Tyan, both students in Harvard University’s joint MD/MBA program in Boston, presented these studies at the meeting.
COVID-19 incidence with ICIs
Mr. Pahalyants and colleagues analyzed data from cancer patients treated in the Mass General Brigham health care system. The researchers compared 1,545 patients with at least one ICI prescription between July 1, 2019, and Feb. 29, 2020, with 20,418 matched cancer patients not prescribed ICIs. The team assessed COVID-19 incidence based on positive test results through June 19, 2020, from public health data.
The incidence of COVID-19 was low in both groups – 1.4% in the ICI group and 1.0% in the matched control group (P = .16). Among COVID-19–positive patients, the all-cause death rate was 40.9% in the ICI group and 28.6% in the control group (P = .23).
In multivariate analysis, patients prescribed ICIs did not have a significantly elevated risk for COVID-19 relative to peers not prescribed ICIs (OR, 1.38; P = .15). However, risk was significantly increased for female patients (OR, 1.74; P < .001), those living in a town or county with higher COVID-19 positivity rate (OR, 1.59; P < .001), and those with severe comorbidity (vs. mild or moderate; OR, 9.77; P = .02).
Among COVID-19–positive patients, those prescribed ICIs did not have a significantly elevated risk for all-cause mortality (OR, 1.60; P = .71), but male sex and lower income were associated with an increased risk of death.
“We did not identify an increased risk of [COVID-19] diagnosis among patients prescribed ICIs compared to the controls,” Mr. Pahalyants said. “This information may assist patients and their providers in decision-making around continuation of therapy during this protracted pandemic. However, more research needs to be conducted to determine potential behavioral and testing factors that may have affected COVID-19 diagnosis susceptibility among patients included in the study.”
COVID-19 mortality with ICIs
For their study, Mr. Tyan and colleagues identified 25 cancer patients who had received ICIs in the year before a COVID-19 diagnosis between March 20, 2020, and June 3, 2020, at the Dana-Farber Cancer Institute and Mass General Brigham network. The researchers then matched each patient with a cancer patient having a COVID-19 diagnosis who had not received ICIs during the preceding year.
Overall, 28% of patients who had received ICIs before their COVID-19 diagnosis died from COVID-19, compared with 36% of those who had not received ICIs.
In multivariate analysis, ICI therapy did not predict COVID-19 mortality (OR, 0.36; P = .23). However, the risk of death from COVID-19 increased with age (OR, 1.14; P = .01) and for patients with chronic obstructive pulmonary disease (OR, 12.26; P = .01), and risk was lower for statin users (OR, 0.08; P = .02). Findings were similar in an analysis restricted to hospitalized patients in the ICI group and their matched controls.
Two ICI-treated patients with COVID-19 had persistent immune-related adverse events (hypophysitis in both cases), and one ICI-treated patient developed a new immune-related adverse event (hypothyroidism).
At COVID-19 presentation, relative to counterparts who had not received ICIs, patients who had received ICIs had higher platelet counts (P = .017) and higher D-dimer levels (P = .037). In the context of similar levels of other biomarkers, this finding is “of unclear significance, as all deaths in the cohort were due to respiratory failure as opposed to hypercoagulability,” Mr. Tyan said.
The patients treated with ICIs were more likely to die from COVID-19 if they had elevated troponin levels (P = .01), whereas no such association was seen for those not treated with ICIs.
“We found that ICI therapy is not associated with greater risk for COVID-19 mortality. Our period of follow-up was relatively short, but we did not observe a high incidence of new or persistent immune-related adverse events among our patients taking ICIs,” Mr. Tyan said.
“While larger prospective trials are needed to evaluate long-term safety in the context of COVID-19 infection, our findings support the continuation of ICI therapy during the pandemic as it does not appear to worsen outcomes for cancer patients,” he concluded.
ICI therapy can continue, with precautions
“The question of susceptibility to COVID-19 has been unclear as ICIs do not necessarily cause immunosuppression but certainly result in modulation of a patient’s immune system,” said Deborah Doroshow, MD, PhD, assistant professor at the Tisch Cancer Institute Icahn School of Medicine at Mount Sinai, New York. She was not involved in these studies.
“The findings of the study by Pahalyants and colleagues, which used a very large sample size, appear to convincingly demonstrate that ICI receipt is not associated with an increased susceptibility to COVID-19,” Dr. Doroshow said in an interview.
However, the findings of the study by Tyan and colleagues are more “thought-provoking,” Dr. Doroshow said. She noted that a large study published in Nature Medicine showed previous ICI therapy in cancer patients with COVID-19 increased the risk for hospitalization or severe COVID-19 requiring high-flow oxygen or mechanical ventilation. The new study was much smaller and did not perform statistical comparisons for outcomes such as oxygen requirements.
“I would feel comfortable telling patients that the data suggests that ICI treatment does not increase their risk of COVID-19. However, if they were to be diagnosed with COVID-19, it is unclear whether their previous ICI treatment increases their risk for poor outcomes,” Dr. Doroshow said.
“I would feel comfortable continuing to treat patients with ICIs at this time, but because we know that patients with cancer are generally more likely to develop COVID-19 and have poor outcomes, it is critical that our patients be educated about social distancing and mask wearing to the extent that their living and working situations permit,” she added.
Mr. Pahalyants disclosed no relevant conflicts of interest, and his study did not receive any specific funding. Mr. Tyan disclosed that he is cofounder and chief science officer of Kinnos, and his study did not receive any specific funding. Dr. Doroshow disclosed no relevant conflicts of interest.

Circulating miRNA could be a potential biomarker for early diagnosis of MM
Circulating microRNAs (miRNAs) could be a potential noninvasive biomarker for early diagnosis of multiple myeloma (MM), according to the results of a meta-analysis published online in the Journal of Bone Oncology.
In recent years, because of the rise of the miRNA technique, many scholars have studied its value in the diagnosis of MM, and have obtained good but inconsistent results, according to Shuai-Shuai Gao, of the Xi’an (China) Daxing Hospital, and colleagues. For this reason, they conducted the meta-analysis in order to more clearly determine the role of miRNA in the early diagnosis of MM. The meta-analysis ultimately assessed 32 studies from 15 articles comprising 2,053 MM patients and 1,118 healthy controls.
All the included studies involved newly diagnosed MM patients and healthy controls; the obtained miRNA was derived from serum or plasma specimens; and the report contained relevant statistics such as sensitivity, specificity, and area-under-the-curve values.
High sensitivity and specificity
The researchers found that the overall sensitivity and specificity of using miRNAs for the diagnosis of MM were 0.81 and 0.85, respectively. In addition, the overall positive likelihood ratio, negative likelihood ratio, diagnostic odds ratio, and area under the curve were 5.5, 0.22, 25 and 0.90, respectively.
A subgroup analysis showed that the down-regulation of miRNA clusters with larger samples size of plasma type could carry out a better diagnostic accuracy of MM patients, according to the authors.
“[Circulating miRNAs] not only had high sensitivity and strong specificity, but also had noninvasive and no radiation risks. It is worth continuing to optimize its practicality. In the future, multicenter, more rigorous, and high-quality case-control studies are still needed in clinical practice to improve the efficacy of circulating miRNA in the early diagnosis of MM,” the researchers concluded.
The study did not receive any outside funding and the researchers reported that they had no conflicts.
