FDA approves trastuzumab-deruxtecan for HER2-low breast cancer

The Food and Drug Administration has approved trastuzumab deruxtecan (Enhertu, Daiichi Sankyo/ AstraZeneca) for the treatment of patients with unresectable or metastatic HER2-low breast cancer.

This is the first therapy approved for HER2-low breast cancer, a newly defined subset of HER2-negative breast cancer in which there are some HER2 proteins on the cell surface, but not enough to warrant classification as HER2-positive cancer, the FDA said in a press release.

The indication is for patients who have received prior chemotherapy in the metastatic setting or for patients whose cancer has returned during adjuvant chemotherapy or within 6 months of completing it.

Approval was based on the DESTINY-Breast04 trial, which included 557 patients with unresectable or metastatic HER2-low breast cancer. The trial had two cohorts: 494 hormone receptor–positive (HR+) patients, and 63 hormone receptor–negative (HR–) patients.



Of these patients, 373 were randomly assigned to received trastuzumab deruxtecan every 3 weeks, and 184 were randomly assigned to receive physician’s choice of chemotherapy (eribulin, capecitabine, gemcitabine, nab paclitaxel, or paclitaxel).

Among patients who received trastuzumab deruxtecan, progression-free survival was longer (10.1 months vs. 5.4 months), as was overall survival (23.9 months vs. 17.5 months), compared with those in the chemotherapy group.

“Overall, these results establish HER2-low metastatic breast cancer as a targetable population of breast cancer with trastuzumab deruxtecan as a new standard of care in this setting,” Shanu Modi, MD, said in June at a press conference held during the annual meeting of the American Society of Clinical Oncology, where she presented the results.

The most common adverse reactions in the trial were nausea, fatigue, alopecia, vomiting, constipation, decreased appetite, musculoskeletal pain, and diarrhea. The agent carries a boxed warning regarding the risk of interstitial lung disease and embryo-fetal toxicity.

The targeted agent is not recommended for women who are pregnant.

Node-negative triple-negative breast cancer prognosis lies within stromal lymphocytes

Article Type
Changed
Wed, 01/04/2023 - 17:16

Young women with a new diagnosis of node-negative triple-negative breast cancer (TNBC) who have high levels of stromal tumor-infiltrating lymphocytes (sTILs) have a very good long-term prognosis, and may be suitable candidates for reduced intensity pre- or postoperative chemotherapy, according to a team of European investigators.

Among 441 women in a Dutch cancer registry who were younger than 40 when they were diagnosed with node-negative TNBC and had not undergone systemic therapy, those who had 75% or more TILs in the intratumoral stromal area had a 15-year cumulative incidence of distant metastases or death of just 2.1%, and every 10% increase in sTILs was associated with a 19% decrease in the risk of death.

In contrast, the 15-year cumulative incidence of distant metastases was 38.4% for women with stromal TIL scores of less than 30%, according to researchers writing in the Journal of Clinical Oncology.

“These data could be used as a starting point for designing a randomized controlled chemotherapy de-escalation trial. The current study confirms the importance of sTILs as a valuable addition to the set of standard prognostic factors in patients with TNBC,” wrote the researchers, who were led by Sabine C. Linn, MD, of the Netherlands Cancer Institute, Amsterdam.
 

Markers for immune response

Stromal TILs, a mixture of mononuclear immune cells, have been shown in previous studies to be prognostic for outcomes in patients with early-stage TNBC treated either with or without neoadjuvant or adjuvant chemotherapy.

For example, investigators cited a study published in JCO in 2014, that showed among women with TNBC enrolled in the phase 3 ECOG 2197 clinical trial and the related ECOG 119 clinical trial, after a nearly 11-year follow-up, higher sTIL scores were associated with significantly better prognosis with every 10% increase translating into a 14% reduction in the risk of recurrence or death (P = .02).

“The prognostic importance of sTILs is, however, unexplored in patients diagnosed under age 40 years, let alone in the subgroup of systemic therapy–naive patients,” Dr. Linn and colleagues wrote.
 

Retrospective study

To see whether the prognostic value of sTILs was as strong among young, systemic therapy–naive women, the investigators conducted a retrospective study of women enrolled in the Netherlands Cancer Registry who were diagnosed with node-negative TNBC from 1989 to 2000. The patients selected had undergone only locoregional treatment, including axillary node dissection, but had not received any systemic therapy.

Pathologists reviewed samples, with TILs reported for the stromal compartment. The samples were grouped by sTIL score categories of high (75% or greater), intermediate (30% to less than 75%), or low (less than 30%). The investigators looked at overall survival (OS) and distant metastasis-free survival (DMFS) stratified by sTIL scores,

During a median follow-up of 15 years, 107 women died or developed distant metastases, and 78 experienced a second primary cancer.

The results were as noted, with patients in the highest category of sTILs having very low rates of either death or distant metastases during follow-up.

“We confirm the prognostic value of sTILs in young patients with early-stage N0 TNBC who are systemic therapy naive by taking advantage of a prospectively collected population-based cohort. Increasing sTILs are significantly associated with improved OS and DMFS. Patients with high sTILs (> 75%) had an excellent 10-year overall survival and a very low 10-year incidence of distant metastasis or death.

The study was supported by grants from The Netherlands Organization for Health Research and Development, A Sister’s Hope, De Vrienden van UMC Utrecht, Agilent Technologies, the Dutch Cancer Society, and Breast Cancer Research Foundation. Dr. Linn reported consulting with and receiving compensation from Daiichi Sankyo, as well as receiving research funding from Genentech/Roche, AstraZeneca, Bristol-Myers Squibb, Tesaro, Merck, Immunomedics, Eurocept Pharmaceuticals, Agendia, and Novartis.

Life and death decisions: What keeps oncologists up at night

Article Type
Changed
Tue, 02/07/2023 - 12:08

It was 2 a.m. And Rebecca Shatsky, MD, could not sleep.

The breast oncologist was thinking about a patient of hers with metastatic cancer.

The patient’s disease had been asymptomatic for some time. Then without warning, her cancer suddenly exploded. Her bone marrow was failing, and her liver was not far behind.

Dr. Shatsky had a treatment plan ready to go but still, she felt uneasy.

“I had to be honest with her that I didn’t know if this plan would work,” says Dr. Shatsky, a medical oncologist at University of California, San Diego (UCSD).

That night, after visiting the patient in the hospital, Dr. Shatsky lay awake going over her next move, making sure it was the right one and hoping it would help keep the disease at bay.

“It’s so much pressure when someone is depending on you to make life or death decisions,” Dr. Shatsky said.

And in the quiet hours of night, these concerns grow louder.

Dr. Shatsky is not alone. Oncologists face difficult decisions every day, and many wrestle with these choices long after their day in the clinic is over.

“There’s no off button,” says Aaron Goodman, MD, a hematologist at UCSD Health who goes by “Papa Heme” on Twitter. “I’m always thinking about my patients. Constantly.”

The public rarely gets a glimpse of these private moments. On occasion, oncologists will share a personal story, but more often, insights come from broad research on the ethical, emotional, and psychological toll of practicing medicine.

Many oncologists carry this baggage home with them because they have no other option.

“There is simply no time to process the weight of the day when I’ve got seven more patients who need my full attention before lunch,” Mark Lewis, MD, director, department of gastrointestinal oncology, Intermountain Healthcare, Salt Lake City, Utah. “That is why my processing happens outside of the office, when my brain can be quiet.”
 

What am I missing?

Dr. Goodman recognizes the gravity of each decision he makes. He pores over every detail of a patient’s scans, lab results, history, and symptoms.

But no matter how many times he checks and rechecks, one question nags at him: What am I missing?

For Dr. Goodman, this exhaustive level of attention is worth it.

“When errors are made, it’s someone’s life,” Dr. Goodman said. “Nothing would have prepared me for this responsibility. Until it lies on you, it’s impossible to understand how much trust patients put into us.”

That trust becomes most apparent for Dr. Goodman when facing a decision about how to treat a patient with acute myeloid leukemia who’s in remission.

Give more chemotherapy to root out the leukemia cells still lurking in the body, and the patient faces a high risk of the cancer returning. Pick stem cell transplant, and the chance of being cured goes up significantly, but the patient could also die within 100 days of the transplant.

“All together, the data show I’m helping patients with a transplant, but for the individual, I could be causing harm. Someone could be living less because of a decision I made,” Dr. Goodman said.

For patients with advanced cancer, oncologists may need to think several moves ahead. Mapping out a patient’s treatment options can feel like a game of chess. Dr. Shatsky is always trying to anticipate how the tumor will behave, what is driving it, and how lifestyle factors may influence a patient’s response in the present and the future.

“It is a mind game,” she says. “Like in chess, I try to outsmart my opponent. But with advanced cancer, there are not necessarily clear-cut guidelines or one way to manage the disease, and I have to do the best I can with drugs I have.”

That’s the art of oncology: Balancing the many knowns and unknowns of a person’s cancer alongside the toxicities of treatment and a patient’s hopes and goals.

Throughout the year, Don Dizon, MD, will see a number of patients with advanced disease. In these instances, the question he often wrestles with is if the patient can’t be cured, whether more treatment will just cause greater harm.

Dr. Dizon recently faced this dilemma with an older patient with metastatic disease who had not done well with an initial treatment regimen. After outlining the risks for more chemotherapy, he explained one option would be to forgo it and simply treat her symptoms.

“It’s an impossible choice,” says Dr. Dizon, director of women’s cancers at Lifespan Cancer Institute and director of medical oncology at Rhode Island Hospital, Providence.

Chemotherapy can provide symptom relief, but it can also be toxic – and patients may be so frail, they can die from more therapy.

“I told my patient, if in your heart, you want to try more therapy, that’s okay. But it’s also okay if you don’t,” Dr. Dizon recalled.

Her response: “You’re supposed to give me the answer.”

However, for patients approaching the end of life, there often is no right answer. 

“It’s part of the discomfort you live with as a patient and oncologist, and when I leave the clinic, that’s one thing that follows me home,” Dr. Dizon said. “At the end of the day, I need to look in the mirror and know I did the best I could.”
 

 

 

The difficult conversation

Every Sunday, Dr. Lewis feels the weight of the week ahead. He and his wife, a pediatrician, call it the “Sunday scaries.”

It’s when Dr. Lewis begins thinking about the delicate conversations to come, rehearsing how he’s going to share the news that a person has advanced cancer or that a cancer, once in remission, has returned.

“Before the pandemic, I had 36 people come to a visit where I delivered some very heavy news and it became a Greek chorus of sobbing,” he recalls.

For every oncologist, delivering bad news is an integral part of the job. But after spending months, sometimes years, with a patient and the family, Dr. Lewis knows how to take the temperature of the room – who will likely prefer a more blunt style and who might need a gentler touch.

“The longer you know a patient and family, the better you can gauge the best approach,” Dr. Lewis said. “And for some, you know it’ll be complete devastation no matter what.”

When Jennifer Lycette, MD, prepares for a difficult conversation, she’ll run down all the possible ways it could go. Sometimes her brain will get stuck in a loop, cycling through the different trajectories on repeat.

“For years, I didn’t know how to cope with that,” said Dr. Lycette, medical director at Providence Oncology and Hematology Care Clinic in Seaside, Ore. “I wasn’t taught the tools to cope with that in my medical training. It took midcareer professional coaching that I sought out on my own to learn to remind myself that no matter what the person says, I have the experience and skill set to handle what comes next and to simply be present in the moment with the patient.”

The question that now sits with Dr. Lycette hours after a visit is what she could have done better. She knows from experience how important it is to choose her words carefully.

Early in her career, Dr. Lycette had a patient with stage IV cancer who wanted to know more about the death process. Because most people ask about pain, she assured him that he likely wouldn’t experience too much pain with his type of cancer.

“It will probably be like falling asleep,” said Dr. Lycette, hoping she was offering comfort. “When I saw him next, he told me he hadn’t slept.”

He was afraid that if he did, he wouldn’t wake up.

In that moment, Dr. Lycette realized the power that her words carry and the importance of trying to understand the inner lives of her patients.
 

Life outside the clinic

Sometimes an oncologist’s late-night ruminations have little to do with cancer itself.

Manali Patel, MD, finds herself worrying if her patients will have enough to eat and whether she will be able to help.

“I was up at 3 a.m. one morning, thinking about how we’re going to fund a project for patients from low-income households who we discovered were experiencing severe food insecurity – what grants we need, what foundations we can work with,” said Dr. Patel, a medical oncologist at Stanford Hospital and Clinics and the VA Palo Alto Health Care System in California.

The past few years of the pandemic have added a new layer of worry for Dr. Patel.

“I don’t want my patients to die from a preventable virus when they’ve already been through so much suffering,” Dr. Patel said.

This thought feeds worries about how her actions outside the clinic could unintentionally harm her patients. Should she go to a big medical conference? A family gathering? The grocery store?

“There are some places you can’t avoid, but these decisions have caused a lot of strife for me,” she said. “The health and safety of our patients – that’s in our wheelhouse – but so many of the policies are outside of our control.”
 

 

 

The inevitable losses and the wins

For patients with metastatic disease, eventually the treatment options will run out.

Dr. Shatsky likes to be up front with patients about that reality: “There will come a day when I will tell you there’s nothing more I can do, and you need to trust that I’m being honest with you and that’s the truth.”

For Dr. Goodman, the devastation that bad news brings patients and families is glaring. He knows there will be no more normalcy in their lives.

“I see a lot of suffering, but I know the suffering happens regardless of whether I see it or not,” Dr. Goodman said.

That’s why holding on to the victories can be so important. Dr. Goodman recalled a young patient who came to him with a 20-cm tumor and is now cured. “Had I not met that individual and done what I had done, he’d be dead, but now he’s going to live his life,” Dr. Goodman said. “But I don’t wake up at 2 a.m. thinking about that.”

Dr. Shatsky gets a lot of joy from the wins – the patients who do really well, the times when she can help a friend or colleagues – and those moments go a long way to outweigh the hurt, worry, and workload.

When dealing with so much gray, “the wins are important, knowing you can make a difference is important,” Dr. Dizon said.

And there’s a delicate balance.

“I think patients want an oncologist who cares and is genuinely invested in their outcomes but not someone who is so sad all the time,” Dr. Lewis said. “When I lose a patient, I still grieve each loss, but I can’t mourn every patient’s death like it’s a family member. Otherwise, I’d break.”

What would you do if you had terminal cancer?

Dr. Dizon recalled how a friend handled the news. She went home and made dinner, he said.

Ultimately, she lived for many years. She saw her kids get married, met her first grandchild, and had time to prepare, something not everyone gets the chance to do.

That’s why it’s important to “do what you normally do as long as you can,” Dr. Dizon said. “Live your life.”

Dr. Shatsky is always trying to anticipate how the tumor will behave, what is driving it, and how lifestyle factors may influence a patient’s response in the present and the future.

“It is a mind game,” she says. “Like in chess, I try to outsmart my opponent. But with advanced cancer, there are not necessarily clear-cut guidelines or one way to manage the disease, and I have to do the best I can with drugs I have.”

That’s the art of oncology: Balancing the many knowns and unknowns of a person’s cancer alongside the toxicities of treatment and a patient’s hopes and goals.

Throughout the year, Don Dizon, MD, will see a number of patients with advanced disease. In these instances, the question he often wrestles with is if the patient can’t be cured, whether more treatment will just cause greater harm.

Dr. Dizon recently faced this dilemma with an older patient with metastatic disease who had not done well with an initial treatment regimen. After outlining the risks for more chemotherapy, he explained one option would be to forgo it and simply treat her symptoms.

“It’s an impossible choice,” says Dr. Dizon, director of women’s cancers at Lifespan Cancer Institute and director of medical oncology at Rhode Island Hospital, Providence.

Chemotherapy can provide symptom relief, but it can also be toxic – and patients may be so frail, they can die from more therapy.

“I told my patient, if in your heart, you want to try more therapy, that’s okay. But it’s also okay if you don’t,” Dr. Dizon recalled.

Her response: “You’re supposed to give me the answer.”

However, for patients approaching the end of life, there often is no right answer. 

“It’s part of the discomfort you live with as a patient and oncologist, and when I leave the clinic, that’s one thing that follows me home,” Dr. Dizon said. “At the end of the day, I need to look in the mirror and know I did the best I could.”
 

 

 

The difficult conversation

Every Sunday, Dr. Lewis feels the weight of the week ahead. He and his wife, a pediatrician, call it the “Sunday scaries.”

It’s when Dr. Lewis begins thinking about the delicate conversations to come, rehearsing how he’s going to share the news that a person has advanced cancer or that a cancer, once in remission, has returned.

“Before the pandemic, I had 36 people come to a visit where I delivered some very heavy news and it became a Greek chorus of sobbing,” he recalls.

For every oncologist, delivering bad news is an integral part of the job. But after spending months, sometimes years, with a patient and the family, Dr. Lewis knows how to take the temperature of the room – who will likely prefer a more blunt style and who might need a gentler touch.

“The longer you know a patient and family, the better you can gauge the best approach,” Dr. Lewis said. “And for some, you know it’ll be complete devastation no matter what.”

When Jennifer Lycette, MD, prepares for a difficult conversation, she’ll run down all the possible ways it could go. Sometimes her brain will get stuck in a loop, cycling through the different trajectories on repeat.

“For years, I didn’t know how to cope with that,” said Dr. Lycette, medical director at Providence Oncology and Hematology Care Clinic in Seaside, Ore. “I wasn’t taught the tools to cope with that in my medical training. It took midcareer professional coaching that I sought out on my own to learn to remind myself that no matter what the person says, I have the experience and skill set to handle what comes next and to simply be present in the moment with the patient.”

The question that now sits with Dr. Lycette hours after a visit is what she could have done better. She knows from experience how important it is to choose her words carefully.

Early in her career, Dr. Lycette had a patient with stage IV cancer who wanted to know more about the death process. Because most people ask about pain, she assured him that he likely wouldn’t experience too much pain with his type of cancer.

“It will probably be like falling asleep,” said Dr. Lycette, hoping she was offering comfort. “When I saw him next, he told me he hadn’t slept.”

He was afraid that if he did, he wouldn’t wake up.

In that moment, Dr. Lycette realized the power that her words carry and the importance of trying to understand the inner lives of her patients.
 

Life outside the clinic

Sometimes an oncologist’s late-night ruminations have little to do with cancer itself.

Manali Patel, MD, finds herself worrying if her patients will have enough to eat and whether she will be able to help.

“I was up at 3 a.m. one morning, thinking about how we’re going to fund a project for patients from low-income households who we discovered were experiencing severe food insecurity – what grants we need, what foundations we can work with,” said Dr. Patel, a medical oncologist at Stanford Hospital and Clinics and the VA Palo Alto Health Care System in California.

The past few years of the pandemic have added a new layer of worry for Dr. Patel.

“I don’t want my patients to die from a preventable virus when they’ve already been through so much suffering,” Dr. Patel said.

This thought feeds worries about how her actions outside the clinic could unintentionally harm her patients. Should she go to a big medical conference? A family gathering? The grocery store?

“There are some places you can’t avoid, but these decisions have caused a lot of strife for me,” she said. “The health and safety of our patients – that’s in our wheelhouse – but so many of the policies are outside of our control.”
 

 

 

The inevitable losses and the wins

For patients with metastatic disease, eventually the treatment options will run out.

Dr. Shatsky likes to be up front with patients about that reality: “There will come a day when I will tell you there’s nothing more I can do, and you need to trust that I’m being honest with you and that’s the truth.”

For Dr. Goodman, the devastation that bad news brings patients and families is glaring. He knows there will be no more normalcy in their lives.

“I see a lot of suffering, but I know the suffering happens regardless of whether I see it or not,” Dr. Goodman said.

That’s why holding on to the victories can be so important. Dr. Goodman recalled a young patient who came to him with a 20-cm tumor and is now cured. “Had I not met that individual and done what I had done, he’d be dead, but now he’s going to live his life,” Dr. Goodman said. “But I don’t wake up at 2 a.m. thinking about that.”

Dr. Shatsky gets a lot of joy from the wins – the patients who do really well, the times when she can help a friend or colleagues – and those moments go a long way to outweigh the hurt, worry, and workload.

When dealing with so much gray, “the wins are important, knowing you can make a difference is important,” Dr. Dizon said.

And there’s a delicate balance.

“I think patients want an oncologist who cares and is genuinely invested in their outcomes but not someone who is so sad all the time,” Dr. Lewis said. “When I lose a patient, I still grieve each loss, but I can’t mourn every patient’s death like it’s a family member. Otherwise, I’d break.”

What would you do if you had terminal cancer?

Dr. Dizon recalled how a friend handled the news. She went home and made dinner, he said.

Ultimately, she lived for many years. She saw her kids get married, met her first grandchild, and had time to prepare, something not everyone gets the chance to do.

That’s why it’s important to “do what you normally do as long as you can,” Dr. Dizon said. “Live your life.”

A version of this article first appeared on Medscape.com.

It was 2 a.m. And Rebecca Shatsky, MD, could not sleep.

The breast oncologist was thinking about a patient of hers with metastatic cancer.

The patient’s disease had been asymptomatic for some time. Then without warning, her cancer suddenly exploded. Her bone marrow was failing, and her liver was not far behind.

Dr. Shatsky had a treatment plan ready to go but still, she felt uneasy.

“I had to be honest with her that I didn’t know if this plan would work,” says Dr. Shatsky, a medical oncologist at University of California, San Diego (UCSD).

That night, after visiting the patient in the hospital, Dr. Shatsky lay awake going over her next move, making sure it was the right one and hoping it would help keep the disease at bay.

“It’s so much pressure when someone is depending on you to make life or death decisions,” Dr. Shatsky said.

And in the quiet hours of night, these concerns grow louder.

Dr. Shatsky is not alone. Oncologists face difficult decisions every day, and many wrestle with these choices long after their day in the clinic is over.

“There’s no off button,” says Aaron Goodman, MD, a hematologist at UCSD Health who goes by “Papa Heme” on Twitter. “I’m always thinking about my patients. Constantly.”

The public rarely gets a glimpse of these private moments. On occasion, oncologists will share a personal story, but more often, insights come from broad research on the ethical, emotional, and psychological toll of practicing medicine.

Many oncologists carry this baggage home with them because they have no other option.

“There is simply no time to process the weight of the day when I’ve got seven more patients who need my full attention before lunch,” Mark Lewis, MD, director, department of gastrointestinal oncology, Intermountain Healthcare, Salt Lake City, Utah. “That is why my processing happens outside of the office, when my brain can be quiet.”
 

What am I missing?

Dr. Goodman recognizes the gravity of each decision he makes. He pores over every detail of a patient’s scans, lab results, history, and symptoms.

But no matter how many times he checks and rechecks, one question nags at him: What am I missing?

For Dr. Goodman, this exhaustive level of attention is worth it.

“When errors are made, it’s someone’s life,” Dr. Goodman said. “Nothing would have prepared me for this responsibility. Until it lies on you, it’s impossible to understand how much trust patients put into us.”

That trust becomes most apparent for Dr. Goodman when facing a decision about how to treat a patient with acute myeloid leukemia who’s in remission.

Give more chemotherapy to root out the leukemia cells still lurking in the body, and the patient faces a high risk of the cancer returning. Pick stem cell transplant, and the chance of being cured goes up significantly, but the patient could also die within 100 days of the transplant.

“All together, the data show I’m helping patients with a transplant, but for the individual, I could be causing harm. Someone could be living less because of a decision I made,” Dr. Goodman said.

For patients with advanced cancer, oncologists may need to think several moves ahead. Mapping out a patient’s treatment options can feel like a game of chess. Dr. Shatsky is always trying to anticipate how the tumor will behave, what is driving it, and how lifestyle factors may influence a patient’s response in the present and the future.

Study confirms BRCA1 and BRCA2 linked to seven cancers

Article Type
Changed
Fri, 12/16/2022 - 10:06

A large case-control study finds the range of cancer types associated with pathogenic variants in BRCA1 and BRCA2 is broader than previously determined from prior analyses showing associations with breast, ovarian, prostate, and pancreatic cancers. The finding, published in JAMA Oncology suggests a possible broader clinical relevance for BRCA1 and BRCA2 genetic testing.

Pathogenic variants in BRCA1 were found to be associated with biliary tract cancer, in BRCA2 with esophageal cancer, and in BRCA1/2 with gastric cancer.

“The results suggest the range of cancer types associated with pathogenic variants in BRCA1 and BRCA2 is likely broader than that determined from previous analysis of largely European ancestry cohorts,” wrote authors who were led by Yukihide Momozawa, DVM, PhD, RIKEN Center for Integrative Medical Sciences, Japan.

“These risk association findings, together with our analysis of an association with family history of cancer and clinical phenotypes, are relevant for developing and adapting guidelines about genetic testing, treatment options, and treatability with PARP [poly adenosine diphosphate-ribose polymerase] inhibitors for each cancer type,” the authors wrote.

Dr. Momozawa and associates conducted a large-scale sequencing study across 14 common cancer types in 63,828 patients (mean age 64 years, 42% female) and 37,086 controls on data drawn from a Japanese nationwide biobank between April 2003 and March 2018. They estimated the risk of each cancer type and determined clinical characteristics associated with pathogenic variant carrier status, while also investigating the utility of family history in detecting patients with pathogenic variants.

Three hundred fifteen pathogenic variants were identified. An odds ratios of greater than 4.0 (with P < 1 × 10−4 as the threshold of significance) for the pathogenic variants were found for biliary tract cancer (OR, 17.4; 95% confidence interval, 5.8-51.9) in BRCA1, esophageal cancer (OR, 5.6; 95% CI, 2.9-11.0) in BRCA2, and gastric cancer (OR, 5.2; 95% CI, 2.6-10.5) in BRCA1, and (OR, 4.7; 95% CI, 3.1-7.1) in BRCA2. Two other cancer types were found to be associated with BRCA1, and four other cancer types with BRCA2. Enrichment of carrier patients was shown in biliary tract, female breast, ovarian, and prostate cancers in accordance with increased numbers of reported cancer types in relatives.

Male patients with breast cancer had a very high carrier frequency of pathogenic variants in BRCA2 (18.9%), but not BRCA1 (1.89%). Patients with ovarian cancer showed the next highest proportion (BRCA1, 4.86%; BRCA2, 3.42%). Frequency exceeding 1% was seen for several other cancer types (two cancer types for BRCA1, four cancer types for BRCA2). More than one cancer types was identified in 4,128 patients (6.3%). Carrier frequency of pathogenic variants in BRCA1 was 0.44% with one cancer type, 0.85% with two cancer types, and 0.69% with three cancer types. It was 0.97%, 1.40%, and 1.74%, respectively, in BRCA2.

“The results of this large-scale registry-based case-control study suggest that pathogenic variants in BRCA1 and BRCA2 were associated with the risk of seven cancer types. These results indicate broader clinical relevance of BRCA1 and BRCA2 genetic testing,” the authors wrote.

PARP inhibitors were developed based on the mechanism in BRCA1 and BRCA2 of homologous recombination repair defects associated with pathogenic variants. PARP inhibitors have been found to have therapeutic efficacy also in pathogenic variants found to be enriched in prostate and pancreatic cancers. While risk for additional cancer types (for example, biliary tract cancer, cervical cancer, colorectal cancer, endometrial cancer, esophageal cancer, and stomach cancer) has been reported after analyzing family members for the presence of pathogenic variants and performing case-control analyses, evidence for an association with these cancer types has not been considered sufficient for them to be adopted into clinical management guidelines, the authors wrote.

In an interview, Dr. Momozawa said that BRCA1 and BRCA2 genetic testing should be expanded in Japan. “But further studies are needed to reveal how much. If a clinical trial of a PARP inhibitor for these three cancer types reveals its clinical utility, the importance of this expansion will increase.”

Dr. Momozawa and associates state that while their selection of controls without a family history of cancer affects the generalizability of the study results, the estimated cumulative risks were comparable with those based on prospective cohorts, suggesting the study design did not greatly affect the results.

Sociogenomics may explain race disparities in breast cancer mortality

Article Type
Changed
Wed, 01/04/2023 - 17:16

Racial differences in cancer outcomes are widespread. Studies indicate that Black people face higher rates of mortality for most cancers than their White counterparts. To bridge this racial gap, researchers need to investigate the biological effects of structural racism and discrimination on cancer outcomes, experts say.

“As a physician, I always like to think that I can influence care in that if I just find the right drugs, help patients understand what their options are, it will help them,” said Ruth Carlos, MD, a radiologist with the University of Michigan Hospital, Ann Arbor. But these things alone are often not enough, because a large proportion of the variation in cancer outcomes is attributable to neighborhood social conditions and the physical environment. “It is incredibly important for us to start to understand just how the neighborhood exerts this effect.”

In a commentary published in the Journal of Clinical Oncology, Dr. Carlos and colleagues highlighted the limitations of previous studies aimed at identifying the causes of racial differences in cancer outcomes. They call upon researchers to turn instead to the long-underexamined biological effects of structural racism and discrimination that contribute to these differences.

In the past, studies on the role of race in health outcomes largely looked at race as a proxy for genetic predisposition. But such an interpretation is flawed, because no genes are specific for a racial or ethnic group, Dr. Carlos and coauthors wrote. Researchers have shown that the vast majority of genetic variation occurs within, rather than between groups.

In an analysis published in Science, researchers reported that within-group differences account for more than 90% of genetic variation.

“Using race in these analyses was not necessarily wrong, but the inferences may have been flawed or incomplete,” Dr. Carlos said. On one hand, looking at genetic predisposition has led to important insights, such as the link between mutations in the BRCA gene and increased risk for breast and ovarian cancer.

However, genetic variation alone is not enough to explain the disparities in cancer outcomes between racial and ethnic groups. The fact that breast cancer can be more aggressive in Black women raises several questions, Dr. Carlos said. Is the cancer worse because Black women have a specific genetic predisposition? Is it worse because Black women exist in a society that marginalizes them and exposes them to increased stress, which in turn produces bad outcomes? Or, could it be both?

Despite progress in the screening, diagnosis and treatment of breast cancer, Black women are 40% more likely to die from the disease than White women. At the time of diagnosis, Black women are more likely to have high-grade, more aggressive breast cancer molecular subtypes, and to have had their cancer spread to the lymph nodes. They also tend to be diagnosed at more advanced stages of breast cancer while at the same time, experience higher rates of false-positive screening results.

Although researchers have hypothesized that genetic differences related to African or European ancestry might contribute, studies have not turned up any differences in cancer susceptibility genes by race. Other factors, such as racial differences in the stage of presentation, molecular subtypes, and disparities in treatment, have also emerged as potential culprits.

In her commentary, Dr. Carlos and colleagues wrote that disparities in breast cancer outcomes previously attributed to race need to be examined from multiple angles. This means looking at both the complex interactions between social conditions and policies, which encompass racism both at the individual and structural level, and stressors such as the experience of discrimination in addition to potential biological and genetic contributions.

Many studies now provide evidence for the harmful effects of racism on health. For breast cancer, specifically, studies also suggest that factors such as racial segregation can influence the stage at which Black women get diagnosed and their likelihood of dying from the disease.

However, an important question that remains is what biological changes occur in women exposed to the kind of persistent low-level stress that is associated with structural racism and discrimination, Dr. Carlos said. “We don’t know what stress pathways actually manifest in the body and how they eventually produce the disease.” Studies to address this issue are important, “especially if you would like to develop interventions to prevent or mitigate disease.”

To address this issue, Dr. Carlos and colleagues called upon the research community to conduct both studies that delineate the underlying biology as well as those that test potential interventions – particularly those associated with breast cancer screening outcomes – to try to shed light on why Black women receive more false positives and diagnoses of more aggressive cancer.

Interventions that can target these specific biological pathways could potentially reduce the negative effects of structural racism and discrimination as well as the effects of other social factors that contribute to breast cancer outcomes, “to ultimately help enhance clinical outcomes and close persistent disparities gaps,” the authors wrote.

Quality of life benefit exaggerated in some cancer studies

Article Type

Fri, 12/16/2022 - 10:06

 

Only a small number of research clinical trials for cancer drugs actually show benefit in quality of life, according to a study published in JAMA Oncology.

The study found trials that failed to show improved quality of life often reported their quality of life outcomes more favorably. Non–immunotherapy-targeted drugs were found to lead to worse quality of life outcomes more often than did cytotoxic agents. And, while there is an association between quality of life benefit and overall survival, no such association was found with progression-free survival.

“In this study, we evaluated the outcomes of cancer drug trials with regard to patients’ quality of life and found that only a quarter of phase 3 cancer drug trials in the advanced-disease setting demonstrated improved quality of life,” wrote authors who were led by Bishal Gyawali, MD, PhD, of the Cancer Research Institute, Queen’s University, Kingston, Ont.

“Improved quality of life outcomes were associated with improved overall survival but not with improved progression-free survival. Importantly, almost half of the cancer drugs drug trials that showed improved progression-free survival showed no improved overall survival or quality of life (i.e., PFS-only benefit). Some reports included conclusions regarding quality of life (QOL) findings that were not directly supported by the trial data, particularly for inferior or non–statistically significant QOL outcomes, thereby framing the findings in a favorable light or downplaying detrimental effects of the study intervention on QOL. Furthermore, contrary to common perception, inferior QOL outcomes were more common with targeted drugs than cytotoxic drugs. Taken together, these findings have important policy implications,” the authors wrote.

These findings are based on the results of a cohort study of 45 phase 3 research clinical trials of 24,806 patients. Only a small percentage of patients showed QOL benefits. The study found that industry-funded clinical trial reports often framed QOL findings more favorably than was warranted by the data.

The study found improved QOL with experimental agents in 11 of 45 randomized controlled trials (24.4%). Studies that reported improved QOL were more likely to also show improved overall survival as compared with trials in which quality of life was not improved (7 of 11 [64%] versus 10 of 34 [29%] trials). For improved progression-free survival, however, there was no positive association (6 of 11 [55%] trials versus 17 of 34 [50%] trials without improved QOL). Among six trials reporting worsening QOL, three (50%) were trials of targeted drugs. Among 11 trials reporting improved QOL, 6 (55%) were trials of immunotherapy drugs. Among the 34 trials in which QOL was not improved compared with controls, the findings were framed favorably (versus neutrally or negatively) in the abstract or conclusions in 16 (47%), an observation that was statistically significantly associated with industry funding (chi-squared = 6.35; P = .01).

“It is important to clearly understand and communicate the effects of cancer drugs”

To fulfill the obligation to inform patients about proposed treatments, the authors wrote that it is important to clearly understand and communicate the effects of cancer drugs on patient quality of life alongside their effects on overall survival and intermediate end points such as progression-free survival. “Patients with advanced cancer expect treatment to help them live longer or have better lives,” the authors wrote. In that respect, in clinical trials of cancer medicines, overall survival and quality of life are the most important measures. Toxicity profiles and disease progression delays do not reliably predict quality of life, and studies have shown poor correlations between quality of life, overall survival, and progression-free survival. This raises the question of validity of progression-free survival as a surrogate endpoint. “Progression-free survival is meaningless without overall survival or quality of life gains,” Dr. Gyawali said in an interview.

Writing in The Lancet Oncology in March, Dr. Gyawali stated that, because progression free survival “does not directly measure how a patient feels or functions, or how long a patient lives, progression-free survival was not intended to inform clinical practice or establish whether a new therapy provides clinically meaningful benefits for patients. However, over the past 2 decades, it has become the most common primary endpoint in oncology clinical trials. We are deeply worried about how the term survival in this phrase can influence clinical practice and patient choices. We propose replacing the phrase progression-free survival with a less ambiguous term: progression-free interval.”

In JAMA Oncology, Dr. Gyawali aimed to elucidate relationships between QOL, overall survival, and progression-free survival, and to assess, as well, how QOL results are framed, especially in industry-sponsored research. When drug trials they analyzed showed no change in QOL but reported that QOL did not worsen or QOL was maintained rather than stating that QOL did not improve, or if there was downplaying of worse QOL outcomes, the study had favorable interpretation, Dr. Gyawali and associates wrote. The expectation of patients receiving cancer drugs would be improved QOL rather than “not worse” QOL, Dr. Gyawali said.

Regarding the finding that QOL outcomes were described as favorable in 47% of trials with unimproved QOL outcomes, Dr. Gyawali said, “the bias in reporting should be corrected by the reviewers and editors of journals. Also, quality of life reporting should be made mandatory. Without unbiased quality of life information, informed decision making on whether or not to use a certain drug is impossible. Patients and physicians need to know that information. Regulators can demand that this should be mandatory in all trials in noncurative settings.”

He remarked further on the worsening QOL in some targeted drug trials, “People tout chemo-free regimens as automatically having better quality of life, but that doesn’t seem to be the case. Targeted drugs can have a severe impact on quality of life, probably due to prolonged duration of side effects. Quality of life should be measured and reported for all drugs.”

Dr. Gyawali and associates noted the limitation in that several studies with negative QOL results are not published at all or are published after a considerable delay, so the present observations may understate the issues that have been raised.

Dr. Gyawali declared that he received no funding and disclosed no conflicts of interest for this study.

‘Unexpected’: Breast cancer spreads most during sleep

Article Type
Changed
Fri, 12/16/2022 - 10:06

New research shows that the metastatic spread of breast cancer occurs predominantly during sleep, a discovery the investigators called “striking and unexpected.”

“This has not been shown before [and] we were surprised, indeed,” Nicola Aceto, PhD, professor of molecular oncology, Swiss Federal Institute of Technology Zürich, said in an interview.

The findings carry potential implications for the timing of biopsy and treatment of metastasis-prone cancers, the authors said.

The study was published online in Nature. 

Circulating tumor cells (CTCs) are generally believed to shed constantly or following particular events such as surgery or physical activity; however, the processes that regulate tumor cell metastasis and how circadian rhythms may play into tumorigenesis remain unclear.

To better understand these processes, Dr. Aceto and colleagues collected blood samples from 30 women with breast cancer at 4:00 a.m. and 10:00 a.m. – times representing the body’s resting and active phases, respectively.

The researchers observed that more than 78% of all CTCs obtained were from samples taken during the resting phase.

This finding is astounding, Harrison Ball, a PhD candidate, and Sunitha Nagrath, PhD, with the University of Michigan, Ann Arbor, wrote in Nature News & Views .

Dr. Aceto and colleagues also found that CTCs generated at night divide more quickly and therefore have a higher potential to metastasize, compared with those generated during the day, which “are devoid of metastatic ability,” according to the authors, who obtained similar results in a series of mouse models.

The team also observed that key circadian rhythm hormones (such as melatonintestosterone, and glucocorticoids) regulate CTC generation, and insulin promotes tumor cell proliferation in a time-dependent manner, suggesting a “need for time-controlled approaches for the characterization and treatment of breast cancer,” the authors wrote.
 

Practice changing?

Dr. Ball and Dr. Nagrath said the time-dependent nature of CTC dynamics could very well transform how cancer patients are assessed and treated.

“The data pointing to CTC proliferation and release during the rest phase suggest that doctors might need to become more conscious of when to administer specific treatments,” they wrote.

Both cautioned, however, that large clinical trials would be needed before any consideration of circadian rhythms is incorporated into standard practice. It’s also unclear whether these results in breast cancer hold true for other tumor types.

Mariana G. Figueiro, PhD, who was not involved in the research, agreed that, if studies confirm more metastatic spread at night, “there is an opportunity to treat patients at strategic times.”

Dr. Figueiro, of the Icahn School of Medicine at Mount Sinai, New York, also saw a potential impact on the timing of blood draws. “I think tightening up on how people do biopsies and bloodwork based on circadian time is important.”

Marleen Meyers, MD, agreed that these findings could have many clinical implications.

“The most obvious is that the time of day [that] treatment is administered may influence efficacy,” said Dr. Meyers, clinical professor of medicine at New York University Langone’s Perlmutter Cancer Center.

But, Dr. Meyers noted, the benefits of treating someone at night would need to be weighed against the downsides of interrupting a person’s normal sleep-wake cycle. “If this finding is clinically important it will be a challenge incorporating this into clinical care,” she said.

New research shows that the metastatic spread of breast cancer occurs predominantly during sleep, a discovery the investigators called “striking and unexpected.”

“This has not been shown before [and] we were surprised, indeed,” Nicola Aceto, PhD, professor of molecular oncology, Swiss Federal Institute of Technology Zürich, said in an interview.

The findings carry potential implications for the timing of biopsy and treatment of metastasis-prone cancers, the authors said.

The study was published online in Nature. 

Circulating tumor cells (CTCs) are generally believed to shed constantly or following particular events such as surgery or physical activity; however, the processes that regulate tumor cell metastasis and how circadian rhythms may play into tumorigenesis remain unclear.

To better understand these processes, Dr. Aceto and colleagues collected blood samples from 30 women with breast cancer at 4:00 a.m. and 10:00 a.m. – times representing the body’s resting and active phases, respectively.

The researchers observed that more than 78% of all CTCs obtained were from samples taken during the resting phase.

This finding is astounding, Harrison Ball, a PhD candidate, and Sunitha Nagrath, PhD, with the University of Michigan, Ann Arbor, wrote in Nature News & Views .

Dr. Aceto and colleagues also found that CTCs generated at night divide more quickly and therefore have a higher potential to metastasize, compared with those generated during the day, which “are devoid of metastatic ability,” according to the authors, who obtained similar results in a series of mouse models.

The team also observed that key circadian rhythm hormones (such as melatonintestosterone, and glucocorticoids) regulate CTC generation, and insulin promotes tumor cell proliferation in a time-dependent manner, suggesting a “need for time-controlled approaches for the characterization and treatment of breast cancer,” the authors wrote.
 

Practice changing?

Dr. Ball and Dr. Nagrath said the time-dependent nature of CTC dynamics could very well transform how cancer patients are assessed and treated.

“The data pointing to CTC proliferation and release during the rest phase suggest that doctors might need to become more conscious of when to administer specific treatments,” they wrote.

Both cautioned, however, that large clinical trials would be needed before any consideration of circadian rhythms is incorporated into standard practice. It’s also unclear whether these results in breast cancer hold true for other tumor types.

Mariana G. Figueiro, PhD, who was not involved in the research, agreed that, if studies confirm more metastatic spread at night, “there is an opportunity to treat patients at strategic times.”

Dr. Figueiro, of the Icahn School of Medicine at Mount Sinai, New York, also saw a potential impact on the timing of blood draws. “I think tightening up on how people do biopsies and bloodwork based on circadian time is important.”

Good chemo vs. bad chemo: When too much is a bad thing

Article Type

Fri, 12/16/2022 - 10:06

A new study finds that mortality is significantly higher among patients with advanced solid tumors who are admitted to the hospital for chemotherapy treatment.

The findings – released in a poster session at the annual meeting of the American Society of Clinical Oncology – found that patients with solid tumors were more likely to be treated for nonurgent indications, not be referred to palliative care, and die within 60 days, compared with patients with hematologic malignancies.

Decisions about inpatient chemotherapy should not be uniform and instead should be based on a case-by-case basis, said Natalie Berger, MD, a hematologist-oncologist at Mount Sinai Hospital,, New York, and the study’s lead author.

Inpatient chemotherapy can be appropriate in certain situations, such as when chemotherapy must be given in the hospital and when it must be administered quickly after a patient presents with cancer symptoms and needs relief, she said.

However, “sometimes patients are admitted due to infection, side effects of chemotherapy or cancer, or for reasons unrelated to their cancer, and chemotherapy may be administered when it is not appropriate. It is also overutilized at the end of life which can lead to more aggressive end-of-life care rather than focusing on quality of life and supportive care,” Dr. Berger said.

The study is based on a retrospective chart review of 880 patients admitted to Mount Sinai Hospital between January 2016 and December 2017 to receive chemotherapy.

They found that the type of tumor was used to determine the urgency of an in-hospital stay for chemotherapy (odds ratio, 0.42; 95% CI, 0.25-0.72; P = .001). Patients with solid tumors or older patients or patients with a functional impairment score (Karnofsky Performance Scale) of 50% were less likely to respond to chemotherapy. There was also a decrease in quality of life among these patients, but only 46% of patients with solid tumors and 15% of patients with hematologic malignancies met with a palliative care professional.

One-third (34%) of patients with solid tumors didn’t have urgent indications, 43% of patients had no response to inpatient chemotherapy, and 20% died within 60 days, compared with patients with hematologic malignancies (19%, 19%, and 9%, respectively).

“There are many reasons why this [high mortality rate in patients with solid tumors] may be happening. Solid tumor patients are more often admitted at a later stage of their cancer when they are sicker, and they were also less likely to have a response to inpatient chemotherapy. Older patients and patients with a poor performance status were also less likely to respond to chemotherapy. This indicates that these patients were sicker, and chemotherapy use may not have been appropriate and palliative care may be underutilized,” she said.

Dr. Berger and colleagues have created a standardized protocol to assess “the appropriateness” of inpatient chemotherapy, improve quality of life, and reduce chemotherapy and health care utilization at the end of life. The protocol has been implemented as a pilot program at Mount Sinai Hospital, Dr. Berger said.

“Any inpatient chemotherapy case that meets standard accepted criteria for required inpatient administration are auto-approved through the electronic survey. For cases outside of standard criteria, further information must be inputted to determine appropriateness of inpatient treatment and are then scored electronically and reviewed by committee physicians and pharmacists,” she said.

Gabriel A. Brooks, MD, MPH, an oncologist with Dartmouth Hitchcock Medical Center, Lebanon, N.H., who was not affiliated with the study, said that inpatient chemotherapy treatment is under scrutiny elsewhere as well.

“There has been recognition that patients who are otherwise sick enough to require hospital admission are often too sick to benefit from chemotherapy,” although there are exceptions. “There is certainly a movement to limit inpatient chemotherapy to situations where it is most likely to be beneficial. Some of this is driven by cost pressures. For instance, Medicare pays for inpatient hospitalizations using the DRG [diagnosis-related group] system. Hospitals cannot charge a la carte for treatments given in the hospital. Instead, they are reimbursed at a fixed rate based on the hospital diagnoses. This will often lead to poor reimbursement of high-cost cancer treatments.”

Dr. Brooks said the study offers insight into who’s getting inpatient chemotherapy. However, “what I can’t tell from this poster is how often the solid tumor patients are getting first-line chemotherapy [as] these patients may be presenting late or may have a potentially treatable cancer with a narrow closing window for treatment versus later-line chemotherapy.”

He also noted that patient and family wishes are missing from the research. “This is critical. Patients and families should be informed that inpatient chemotherapy may not provide the benefit they are hoping for, especially for patients with solid tumors starting later lines of therapy. Patients should be informed that there are alternatives to inpatient chemotherapy, such as hospice referral or waiting for possible outpatient treatment – if their condition improves. But when a patient wants to try inpatient chemotherapy and their doctor wants to offer it, then it is likely a reasonable thing to try.”

Going forward, he said, “qualitative study is needed to better understand when and why inpatient chemotherapy is used. There are likely some clear good uses and some clear bad uses of inpatient chemotherapy. Can outpatient regimens be substituted for the regimens where patients are directly admitted? Or, can outpatient protocols be devised for these regimens? Are there specific situations where inpatient chemotherapy is the right thing (leukemia, esophageal cancer with worsening dysphagia, etc.)?”

No study funding was received.

My picks for best of ASCO 2022

CHICAGO – The American Society of Clinical Oncology recently wrapped its annual meeting in Chicago. Many of us attended virtually, or in person, and were wowed by some of the abstracts and their implications for our patients – some practice changing. Here, I highlight some presentations that stood out to me.

A first-line treatment for metastatic colorectal cancer

The plenary session did not disappoint. In abstract LBA1, investigators presented first-line treatment for patients with metastatic colorectal cancer who were randomized to receive mFOLFOX6 with either bevacizumab or panitumumab in RAS wild-type positive patients. This was the phase 3 PARADIGM trial.

Dr. David H. Henry

The primary outcome for this study was overall survival. It included 823 patients who were randomized 1:1 with a subset analysis of whether the primary tumor was on the left or right side of the colon. At 61 months follow-up, the median overall survival results for left-sided colon cancer was 38 months versus 34 months. It was statistically significant favoring the panitumumab arm. It improved the curable resection rate for patients with left-sided tumors from 11% in the bevacizumab arm to 18% in the panitumumab arm. Interestingly, patients randomized with right-sided tumors showed no difference in overall survival. The investigator, Takayuki Yoshino, MD, PhD, National Cancer Center Hospital East, Kashiwa, Japan, said the study findings support the use of mFOLFOX6 with panitumumab in left-sided RAS wild type as first-line therapy in metastatic colorectal patients. 
 

A possible new standard of care in breast cancer

Shanu Modi, MD, of Memorial Sloan Kettering Cancer Center, New York, received a standing ovation and deserved it. In the phase 3 clinical trial DESTINY-Breast04 (abstract LBA3), she demonstrated that trastuzumab deruxtecan (T-DXd) for patients with metastatic breast cancer who were HER2 low (IHC 1+ or 2+ ISH-), led to a statistically significant and clinically meaningful benefit in both progression free survival and overall survival. In this trial, patients were randomized 2:1 to receive trastuzumab deruxtecan or physician’s choice of chemotherapy. All patients had at least one to two lines of chemotherapy before entering the trial. Hormone-positive patients were allowed if they had already received and failed, or progressed on hormone therapy. 

Previously, most patients were treated either with eribulin with some receiving capecitabine, gemcitabine or taxane, or hormone therapy if hormone positive.

The progression-free survival was 10.1 versus 5.4 months in hormone-positive patients, and in all patients (hormone receptor positive or negative), there was a likewise improvement of 9.9 versus 5.1 months progression free survival.

Overall survival was equally impressive. In the hormone receptor–positive patients, the hazard ratio was 0.64 with a 23.9 versus 17.5 month survival. If all patients were included, the HR was again 0.64 with 23.4 versus 16.8 month survival. Even the triple-negative breast cancer patients had a HR of 0.48 with 18.2 versus 8.3 months survival. Adverse events were quite tolerable with some nausea, some decreased white count, and only an interstitial lung disease of grade 2 or less in 12%. 

Trastuzumab deruxtecan is a targeted treatment which, in addition to striking its target, also targets other tumor cells that are part of the cancer. The results of this study may lead to a new standard of care of this patient population.

The study by Dr. Modi and colleagues was simultaneously published in the New England Journal of Medicine.
 

 

 

Improving outcomes in multiple myeloma

In abstract LBA4, Paul G. Richardson, MD, of the Dana-Farber Cancer Institute, Boston, asks if autologous stem cell transplant (ASCT) can improve outcomes after induction with an RVD regimen (lenalidomide, bortezomib, and dexamethasone) and lenalidomide (Revlimid) maintenance for newly diagnosed patients with multiple myeloma in the DETERMINATION study.

The take home here was quite interesting. In fact, there is no difference in overall survival if patients get this standard RVD/lenalidomide maintenance induction with or without ASCT. However, the progression free survival was better with ASCT: 46 versus 67 months (improvement of 21 months). However, there were some caveats. There was toxicity and change in quality of life for a while in those patients receiving ASCT as would be expected. Furthermore, the study only allowed 65 years old or younger and ASCT may not be wise for older patients. The discussant made a strong point that African Americans tend to have higher risk disease with different mutations and might also be better served by have ASCT later.

The conclusion was that, given all the new therapies in myeloma for second line and beyond, ASCT should be a discussion with each new patient and not an automatic decision.

This study was simultaneously published in the New England Journal of Medicine.
 

Adagrasib promising for pretreated patients with NSCLC with KRAS mutation

In patients with advanced or metastatic non–small cell lung cancer (NSCLC), adagrasib was found to be well tolerated and “demonstrates promising efficacy” for patients with the KRAS G12C mutation (KRYSTAL-1, abstract 9002). This was a phase 2 registration trial of 116 patients who were treated with 600 mg of adagrasib twice orally. Patients all had previous chemotherapy or immunotherapy or both. The overall response rate was a surprisingly good 43% (complete response and partial response). Disease control was an incredible 80% if stable disease was included. The duration of response was 8.5 months, progression-free survival was 6.5 months, and overall survival was 12.6 months. Furthermore, 33% of those with brain metastases had a complete response or partial response.

The take-home message is that, since 15% of NSCLC metastatic patients are KRAS mutant G12C, we should be watching for such patients in our biomarker analysis. While we have sotorasib – approved by the Food and Drug Administration for NSCLC – the results of this study suggests we may have another new molecule in the same class.
 

Neoadjuvant chemotherapy with immunotherapy for NSCLC

It may be time to consider neoadjuvant chemotherapy with immunotherapy, such as nivolumab, for patients with NSCLC in order to achieve the best response possible.

In NADIM II, investigators led by Mariano Provencio-Pulla, MD, of the Hospital Universitario Puerta de Hierro-Majadahonda, Madrid, confirmed the superiority of chemotherapy with immunotherapy for patients with resectable stage IIIA NSCLC. NADIM included patients with resectable stage IIIA/B NSCLC who were randomized 2:1 to receive carboplatin taxol neoadjuvant therapy with or without nivolumab before and after surgery. The pathological complete response rates overall were 36% versus 7%, favoring the nivolumab arm, but even higher pCR rates occurred in patients with PD-L1 over 50%.

In closing, always check MMR, KRAS, BRAF, and HER2. For wild-type left-sided mCRC, consider FOLFOX or FOLFIRI with an anti-EGFR. For KRAS mutant or right-sided colon tumor, consider FOLFOX or FOLFIRI with bevacizumab, followed by maintenance 5FU or capecitabine, with or without bevacizumab.

In this trial, patients were randomized 2:1 to receive trastuzumab deruxtecan or physician’s choice of chemotherapy. All patients had at least one to two lines of chemotherapy before entering the trial. Hormone-positive patients were allowed if they had already received and failed, or progressed on hormone therapy. 

Previously, most patients were treated either with eribulin with some receiving capecitabine, gemcitabine or taxane, or hormone therapy if hormone positive.

The progression-free survival was 10.1 versus 5.4 months in hormone-positive patients, and in all patients (hormone receptor positive or negative), there was a likewise improvement of 9.9 versus 5.1 months progression free survival.

Overall survival was equally impressive. In the hormone receptor–positive patients, the hazard ratio was 0.64 with a 23.9 versus 17.5 month survival. If all patients were included, the HR was again 0.64 with 23.4 versus 16.8 month survival. Even the triple-negative breast cancer patients had a HR of 0.48 with 18.2 versus 8.3 months survival. Adverse events were quite tolerable with some nausea, some decreased white count, and only an interstitial lung disease of grade 2 or less in 12%. 

Trastuzumab deruxtecan is a targeted treatment which, in addition to striking its target, also targets other tumor cells that are part of the cancer. The results of this study may lead to a new standard of care of this patient population.

The study by Dr. Modi and colleagues was simultaneously published in the New England Journal of Medicine.
 

 

 

Improving outcomes in multiple myeloma

In abstract LBA4, Paul G. Richardson, MD, of the Dana-Farber Cancer Institute, Boston, asks if autologous stem cell transplant (ASCT) can improve outcomes after induction with an RVD regimen (lenalidomide, bortezomib, and dexamethasone) and lenalidomide (Revlimid) maintenance for newly diagnosed patients with multiple myeloma in the DETERMINATION study.

The take home here was quite interesting. In fact, there is no difference in overall survival if patients get this standard RVD/lenalidomide maintenance induction with or without ASCT. However, the progression free survival was better with ASCT: 46 versus 67 months (improvement of 21 months). However, there were some caveats. There was toxicity and change in quality of life for a while in those patients receiving ASCT as would be expected. Furthermore, the study only allowed 65 years old or younger and ASCT may not be wise for older patients. The discussant made a strong point that African Americans tend to have higher risk disease with different mutations and might also be better served by have ASCT later.

The conclusion was that, given all the new therapies in myeloma for second line and beyond, ASCT should be a discussion with each new patient and not an automatic decision.

Adagrasib promising for pretreated patients with NSCLC with KRAS mutation

In patients with advanced or metastatic non–small cell lung cancer (NSCLC), adagrasib was found to be well tolerated and “demonstrates promising efficacy” for patients with the KRAS G12C mutation (KRYSTAL-1, abstract 9002). This was a phase 2 registration trial of 116 patients who were treated with 600 mg of adagrasib twice orally. Patients all had previous chemotherapy or immunotherapy or both. The overall response rate was a surprisingly good 43% (complete response and partial response). Disease control was an incredible 80% if stable disease was included. The duration of response was 8.5 months, progression-free survival was 6.5 months, and overall survival was 12.6 months. Furthermore, 33% of those with brain metastases had a complete response or partial response.

The take-home message is that, since 15% of NSCLC metastatic patients are KRAS mutant G12C, we should be watching for such patients in our biomarker analysis. While we have sotorasib – approved by the Food and Drug Administration for NSCLC – the results of this study suggests we may have another new molecule in the same class.
 

Neoadjuvant chemotherapy with immunotherapy for NSCLC

It may be time to consider neoadjuvant chemotherapy with immunotherapy, such as nivolumab, for patients with NSCLC in order to achieve the best response possible.

In NADIM II, investigators led by Mariano Provencio-Pulla, MD, of the Hospital Universitario Puerta de Hierro-Majadahonda, Madrid, confirmed the superiority of chemotherapy with immunotherapy for patients with resectable stage IIIA NSCLC. NADIM included patients with resectable stage IIIA/B NSCLC who were randomized 2:1 to receive carboplatin taxol neoadjuvant therapy with or without nivolumab before and after surgery. The pathological complete response rates overall were 36% versus 7%, favoring the nivolumab arm, but even higher pCR rates occurred in patients with PD-L1 over 50%.

In closing, always check MMR, KRAS, BRAF, and HER2. For wild-type left-sided mCRC, consider FOLFOX or FOLFIRI with an anti-EGFR. For KRAS mutant or right-sided colon tumor, consider FOLFOX or FOLFIRI with bevacizumab, followed by maintenance 5FU or capecitabine, with or without bevacizumab.

CHICAGO – The American Society of Clinical Oncology recently wrapped its annual meeting in Chicago. Many of us attended virtually, or in person, and were wowed by some of the abstracts and their implications for our patients – some practice changing. Here, I highlight some presentations that stood out to me.

A first-line treatment for metastatic colorectal cancer

The plenary session did not disappoint. In abstract LBA1, investigators presented first-line treatment for patients with metastatic colorectal cancer who were randomized to receive mFOLFOX6 with either bevacizumab or panitumumab in RAS wild-type positive patients. This was the phase 3 PARADIGM trial.

Dr. David H. Henry

The primary outcome for this study was overall survival. It included 823 patients who were randomized 1:1 with a subset analysis of whether the primary tumor was on the left or right side of the colon. At 61 months follow-up, the median overall survival results for left-sided colon cancer was 38 months versus 34 months. It was statistically significant favoring the panitumumab arm. It improved the curable resection rate for patients with left-sided tumors from 11% in the bevacizumab arm to 18% in the panitumumab arm. Interestingly, patients randomized with right-sided tumors showed no difference in overall survival. The investigator, Takayuki Yoshino, MD, PhD, National Cancer Center Hospital East, Kashiwa, Japan, said the study findings support the use of mFOLFOX6 with panitumumab in left-sided RAS wild type as first-line therapy in metastatic colorectal patients. 
 

A possible new standard of care in breast cancer

This breast tumor subtype disproportionately affects Black women

Hormone receptor positive (HR+) basal tumors are biologically analogous to triple negative breast cancer (TNBC), independent of race. That finding, suggested by transcriptomic analyses of a racially diverse cohort that identified racial disparities in the proportion of HR-positive basal tumors, underscores a need for diverse racial representation in clinical trials, researchers recently reported at the annual meeting of the American Society of Clinical Oncology.

The leading cause of cancer-associated death among Black women is breast cancer, and compared with White women, Black women are 41% more likely to die from breast cancer, said Sonya A. Reid, MD, MPH, a medical oncologist with the Vanderbilt-Ingram Cancer Center, Nashville, Tenn., and the study author.

Few studies, Dr. Reid said, have evaluated if tumor biology differences contribute to the racial outcome disparity. Hormone receptor-positive tumors classified as basal-type with Blueprint genomic analysis (HR+/Basal) are overrepresented among Black women. These tumors are thought to be similar to triple negative breast cancer tumors (TNBC) which are more aggressive and tend to have worse outcomes.

TNBC, Dr. Reid said, is associated with low ACKR1 expression, which encodes the Duffy antigen and correlates with worse breast cancer outcomes. Given the overrepresentation and worse outcomes among Black women with HR-positive basal tumors, Dr. Reid and colleagues compared differentially expressed genes (DEGs) by race and subtype.

Their analysis of data from 2,657 women with stage 1, 2, and 3 breast cancer, showed that among 455 Black women, 315 had luminal (HR-positive luminal) and 140 had basal tumors (66 HR-positive basal and 74 HR-negative basal). Among White women included as a reference group (n = 2,202), tumors were were HR-positive luminal in 1,825 and HR-positive basal or HR-negative basal in 158 and 219, respectively. The proportion of Black women with HR-positive basal tumors was significantly higher, compared with White women (15% versus 7%; P <0.001) as was the proportion of Black women with HR-negative basal tumors, compared with White women (16% versus 10%; P <0.001).

Women included in the study were participants in the ongoing BEST study (5R01CA204819) at Vanderbilt University Medical Center, Nashvlile, Tenn., or FLEX study (NCT03053193). In a multidimensional scaling analysis, HR-positive basal tumors clustered with TNBC rather than with HR-positive luminal tumors. While a differential gene expression analysis comparing HR-positive basal with HR-positive luminal tumors resulted in over 700 differently expressed genes in Black women, no such genes were identified when comparing HR-positive basal tumors with TNBC. ACKR1 expression in HR-positive basal tumors was comparable to TNBC in Black women (P = 0.81) and White women (P = 0.46). In contrast, HR-positive basal tumors had significantly lower ACKR1 expression than HR-positive luminal tumors in Black (P < 0.01) and White women (P < 0.01).

The findings highlight the importance of further genomic classification for patients with HR-positive tumors, Dr. Reid said.

“Molecular subtype classification is not standard of care for patients with localized breast cancer. However, the current analysis suggests that genomic classification could have important clinical implications. Women with HR-positive basal tumors should not be treated uniformly with HR-poisitive luminal tumors. Our data suggest that HR-positive basal tumors are transcriptomically similar to TNBC tumors and should potentially be treated similar to TNBC,” she said.

There are several genomic tests that are widely available clinically to guide treatment decisions and are covered by insurance, Dr. Reid said. Prior studies have shown racial disparity in the omission of genomic tests to guide treatment decisions, however. “Increasing access [to] and awareness of genomic testing will improve guideline-adherent care for all patients. We must intentionally recruit minority patients into clinical trials, knowing that Black women are more likely to die of their breast cancer,” she said.

A further impediment lies in the fact that while most minority patients receive their care in the community, most clinical trials are offered at large academic centers, Dr. Reid said. Future trials, she urged, should include a predetermined percentage of racial/ethnic groups in the clinical trial design to reflect the breast cancer population.

Limitations of the study included that race was self-reported. She noted further that the data for survival are not yet mature. She added, “We will also be evaluating the association of different systemic treatment options across the different molecular subtypes.”

Dr. Reid reported no relevant disclosures.
