There were no significant differences in COVID-19 outcomes between cases caught by routine screening and screening based on symptoms/exposure history among cancer outpatients treated at Mayo Clinic facilities, according to a review of 224 cases.

The finding led to a shift away from routine COVID-19 screening to screening based on symptoms and exposures, said lead investigator Zhuoer Xie, MD, a hematology/oncology fellow at Mayo’s Rochester, Minn., campus.

“We are so happy” to see these results and be able to move away from routine screening. It’s burdensome and uncomfortable for patients and expensive to administer, Dr. Xie said at the AACR Virtual Meeting: COVID-19 and Cancer (Abstract S06-03).

Also, “our results provide reassurance that cancer care may safely continue during the pandemic with appropriate precautions,” she said.

Like many institutions, Mayo instituted routine COVID-19 screening for cancer outpatients at the start of the pandemic, requiring patients be tested 24 hours before systemic treatment, radiation therapy, or surgery. People on multiday regimens were screened twice a week.

Among 5,452 patients at the Rochester campus and its surrounding satellites, plus Mayo’s facilities in Phoenix and Jacksonville, Fla., routine screening picked up 63 COVID-19 cases (1.2%) from March 18 to July 31, 2020.

The outcomes were compared with 161 COVID-19 cases screened due to symptoms and exposure history. Most of the patients were on cancer surveillance as opposed to active treatment with routine testing.

Overall, 17.5% of cases caught by routine screening (11/63) were hospitalized versus 26.7% of patients screened for risk factors (43/161).

There was one COVID-19-related ICU admission among the 63 routine screening cases (1.6%) and nine ICU admissions (5.6%) among the risk-factor screening group. Three people diagnosed by routine screening (4.8%) died, compared with six deaths in the risk factor screening group (3.7%). The differences were not statistically significant, and there was no difference in treatment delay based on screening method.

The mortality rate was substantially lower than previously reported for COVID-19 among cancer patients, perhaps in part because Mayo facilities were not overwhelmed with cases early in the pandemic, so there was never a shortage of hospital beds and other resources, Dr. Xie said.

“Many of us are glad to see your data. It’s comforting,” said presentation moderator Solange Peters, MD, PhD, head of medical oncology at the Centre Hospitalier Universitaire Vaudois in Lausanne, Switzerland.

With proper precautions, “we can firmly encourage patients to come” in for their “cancer treatment without any hesitation,” Dr. Peters said.

“We feel the same way. We tell our patients this might be the safest place for you to be. Everybody is masked; everybody is taking all the precautions,” said Sheena Bhalla, MD, a hematology/oncology fellow as the Icahn School of Medicine at Mount Sinai, New York.

“We are [also] reaching out to patients who have been hesitant” about the COVID-19 vaccine, Dr. Bhalla said, “and trying to get them vaccinated. We are still learning how cancer patients will do with the vaccine, but we think that some protection is better than no protection.”

Currently at Mayo’s main campus in Rochester and its surrounding clinics, COVID-19 screening is based on symptoms, exposure, and factors such as high risk for neutropenic fever.

Mayo’s Arizona and Florida campuses had a surge of cases a few months ago, so routine screening is still used there but only on a monthly basis for people on active treatment.

Consistent with previous reports, older age and lymphopenia increased the risk of COVID-19 hospitalization in Mayo’s study, but comorbidities and active cancer treatment did not.

COVID-19 patients were a median of 62 years old, and 42% were women. Breast, genitourinary, and gastrointestinal tumors were the most common cancers.

Respiratory failure and sepsis were the most common complications among the 54 hospital admissions; eight patients required intubation.

When early-stage seminoma metastasizes to one or two retroperitoneal lymph nodes, surgical excision is an “attractive” alternative to standard chemotherapy or radiation, according to an investigator from the phase 2 SEMS trial.

The trial enrolled 55 men with early-stage seminoma and isolated retroperitoneal disease, and all of them underwent retroperitoneal lymph node dissection (RPLND). At 2 years, the recurrence rate was 18%, the recurrence-free survival rate was 84%, and the overall survival rate was 100%. Surgical complications occurred in 13% of patients.

“The SEMS trial establishes RPLND as a first-line treatment alternative for testicular seminoma with isolated retroperitoneal lymphadenopathy up to 3 cm ... It’s an attractive option given the favorable long-term morbidity of RPLND,” said co-principal investigator Siamak Daneshmand, MD, of the University of Southern California (USC), Los Angeles.

“The whole point is to offer an alternative treatment that will avoid long-term toxicity ... It makes no sense treating isolated retroperitoneal lymphadenopathy with strong chemotherapy that’s meant for more widely disseminated disease,” Dr. Daneshmand said.

He presented results from the SEMS trial at the 2021 Genitourinary Cancers Symposium (Abstract 375).
 

Practice-changing?

Dr. Daneshmand called the trial results “practice-changing” and noted that surgery “makes sense” to patients and providers, especially because RPLND is already an established option for early-stage non-seminoma testicular cancer. In fact, USC has continued to offer RPLND for early-stage seminoma since this trial ended 2 years ago, Dr. Daneshmand said.

Study discussant Pilar Laguna, MD, PhD, of Istanbul Medipol University in Turkey, offered a different viewpoint. She said the SEMS trial had an “excellent” design, but, due to the relatively short follow-up, she would recommend caution.

“We in Europe do not recommend primary retroperitoneal lymph node dissection in seminoma outside a trial or institutional study,” Dr. Laguna said.

Still, she said the SEMS trial “establishes a solid base” for ongoing prospective trials of primary RPLND in early-stage seminoma.
 

Trial details

The SEMS trial enrolled 55 patients with pure testicular seminoma. They had stage I disease with 1-3 cm relapse (25%) or stage IIA/B disease with no more than two lymph nodes in any dimension (75%). Imaging was done within 6 weeks of surgery to avoid under staging, and serum tumor markers could be no more than 1.5 times the upper limit of normal.

The majority of subjects were White, and the median age was 34 years (range, 21-64 years). Including USC, the trial was conducted at 12 North American sites.

Patients had open modified-template surgeries by surgeons who had performed at least eight open RPLNDs in 1 year or more than 24 in 3 years. Surgeries at USC used a midline approach, with a typical hospital stay of 1 day.

The median follow-up was 2 years. The overall recurrence rate was 18% (10/55), with a median time to recurrence of 8 months.

All 10 cases of recurrence were salvageable – 8 with chemotherapy and 2 with surgical resection. All of the recurrences were retroperitoneal.

“If you can cure 80% [of men] without radiation or chemotherapy, that’s very significant. These are young patients, and chemotherapy and radiation have long-term side effects. The important thing to remember is if men do recur, they are salvageable,” Dr. Daneshmand said.

Seven patients (13%) had surgical complications that were largely minor. The exceptions were one case of pulmonary embolism and one case of chylous ascites that required drainage. There were no long-term complications, including retrograde ejaculation.

The SEMS study was funded by the Think Different Foundation. Dr. Daneshmand and Dr. Laguna said they have no relevant disclosures.

The combined clinical cell-cycle risk (CCR) score – derived from both clinical and genetic factors – can identify patients with intermediate- and high-risk localized prostate cancer who could potentially forgo androgen deprivation therapy (ADT), a retrospective study suggests.

The score can identify patients in whom the risk of metastasis after dose-escalated radiation is so small that adding ADT no longer makes clinical sense, according to investigator Jonathan Tward, MD, PhD, of the Genitourinary Cancer Center at the University of Utah, Salt Lake City.

His group’s study, which included 741 patients, showed that, below a CCR score of 2.112, the 10-year risk of metastasis was 4.2% with radiation therapy (RT) alone and 3.9% with the addition of ADT.

“Whether you have RT alone, RT plus any duration of ADT, insufficient duration ADT, or sufficient ADT duration by guideline standard, the risk of metastasis never exceeds 5% at 10 years” even in high- and very-high-risk men, Dr. Tward said.

He and his team found that half the men in their study with unfavorable intermediate-risk disease, 20% with high-risk disease, and 5% with very-high-risk disease scored below the CCR threshold.

This implies that, for many men, ADT after radiation “adds unnecessary morbidity for an extremely small absolute risk reduction in metastasis-free survival,” Dr. Tward said at the 2021 Genitourinary Cancers Symposium, where he presented the findings (Abstract 195).
 

Value of CCR

The CCR score tells you if the relative metastasis risk reduction with ADT after radiation – about 50% based on clinical trials – translates to an absolute risk reduction that would matter, Dr. Tward said in an interview.

“Each patient has in their own mind what that risk reduction is that works for them,” he added.

For some patients, a 1%-2% drop in absolute risk is worth it, he said, but most patients wouldn’t be willing to endure the side effects of hormone therapy if the absolute benefit is less than 5%.

The CCR score is a validated prognosticator of metastasis and death in localized prostate cancer. It’s an amalgam of traditional clinical risk factors from the Cancer of the Prostate Risk Assessment (CAPRA) score and the cell-cycle progression (CCP) score, which measures expression of cell-cycle proliferation genes for a sense of how quickly tumor cells are dividing.

The CCP test is available commercially as Prolaris. It is used mostly to make the call between active surveillance and treatment, Dr. Tward explained, “but I had a hunch this off-the-shelf test would be very good at” helping with ADT decisions after radiation.
 

‘Uncomfortable’ findings, barriers to acceptance

“People are going to be very uncomfortable with these findings because it’s been ingrained in our heads for the past 20-30 years that you must use hormone therapy with high-risk prostate cancer, and you should use hormone therapy with intermediate risk,” Dr. Tward said.

“It took me a while to believe my own data, but we have used this test for several years to help men decide if they would like to have hormone therapy after radiation. Patients clearly benefit from this information,” he said.

The 2.112 cut point for CCR was determined from a prior study that was presented at GUCS 2020 (Abstract 346) and recently accepted for publication.

In the validation study Dr. Tward presented at GUCS 2021, 70% of patients had intermediate-risk disease, and 30% had high- or very-high-risk disease according to National Comprehensive Cancer Network criteria.

All 741 patients received RT equivalent to at least 75.6 Gy at 1.8 Gy per fraction, with 84% getting or exceeding 79.2 Gy. About half the men (53%) had ADT after RT.

Genetic testing was done on stored biopsy samples years after the men were treated. Half of them were below the CCR threshold of 2.112. For those above it, the 10-year risk of metastasis was 25.3%.

CCR outperformed CCP alone, CAPRA alone, and NCCN risk groupings for predicting metastasis risk after RT.

Though this validation study was “successful,” additional research is needed, according to study discussant Richard Valicenti, MD, of the University of California, Davis.

“Widespread acceptance for routine use faces challenges since no biomarker has been prospectively tested or shown to improve long-term outcome,” Dr. Valicenti said. “Clearly, the CCR score may provide highly precise, personalized estimates and justifies testing in tiered and appropriately powered noninferiority studies according to NCCN risk groups. We eagerly await the completion and reporting of such trials so that we have a more personalized approach to treating men with prostate cancer.”

The current study was funded by Myriad Genetics, the company that developed the Prolaris test. Dr. Tward disclosed relationships with Myriad Genetics, Bayer, Blue Earth Diagnostics, Janssen Scientific Affairs, and Merck. Dr. Valicenti has no disclosures.

He and his team found that half the men in their study with unfavorable intermediate-risk disease, 20% with high-risk disease, and 5% with very-high-risk disease scored below the CCR threshold.

This implies that, for many men, ADT after radiation “adds unnecessary morbidity for an extremely small absolute risk reduction in metastasis-free survival,” Dr. Tward said at the 2021 Genitourinary Cancers Symposium, where he presented the findings (Abstract 195).
 

Value of CCR

The CCR score tells you if the relative metastasis risk reduction with ADT after radiation – about 50% based on clinical trials – translates to an absolute risk reduction that would matter, Dr. Tward said in an interview.

“Each patient has in their own mind what that risk reduction is that works for them,” he added.

For some patients, a 1%-2% drop in absolute risk is worth it, he said, but most patients wouldn’t be willing to endure the side effects of hormone therapy if the absolute benefit is less than 5%.

The CCR score is a validated prognosticator of metastasis and death in localized prostate cancer. It’s an amalgam of traditional clinical risk factors from the Cancer of the Prostate Risk Assessment (CAPRA) score and the cell-cycle progression (CCP) score, which measures expression of cell-cycle proliferation genes for a sense of how quickly tumor cells are dividing.

The CCP test is available commercially as Prolaris. It is used mostly to make the call between active surveillance and treatment, Dr. Tward explained, “but I had a hunch this off-the-shelf test would be very good at” helping with ADT decisions after radiation.
 

‘Uncomfortable’ findings, barriers to acceptance

“People are going to be very uncomfortable with these findings because it’s been ingrained in our heads for the past 20-30 years that you must use hormone therapy with high-risk prostate cancer, and you should use hormone therapy with intermediate risk,” Dr. Tward said.

“It took me a while to believe my own data, but we have used this test for several years to help men decide if they would like to have hormone therapy after radiation. Patients clearly benefit from this information,” he said.

The 2.112 cut point for CCR was determined from a prior study that was presented at GUCS 2020 (Abstract 346) and recently accepted for publication.

In the validation study Dr. Tward presented at GUCS 2021, 70% of patients had intermediate-risk disease, and 30% had high- or very-high-risk disease according to National Comprehensive Cancer Network criteria.

All 741 patients received RT equivalent to at least 75.6 Gy at 1.8 Gy per fraction, with 84% getting or exceeding 79.2 Gy. About half the men (53%) had ADT after RT.

Genetic testing was done on stored biopsy samples years after the men were treated. Half of them were below the CCR threshold of 2.112. For those above it, the 10-year risk of metastasis was 25.3%.

CCR outperformed CCP alone, CAPRA alone, and NCCN risk groupings for predicting metastasis risk after RT.

Though this validation study was “successful,” additional research is needed, according to study discussant Richard Valicenti, MD, of the University of California, Davis.

“Widespread acceptance for routine use faces challenges since no biomarker has been prospectively tested or shown to improve long-term outcome,” Dr. Valicenti said. “Clearly, the CCR score may provide highly precise, personalized estimates and justifies testing in tiered and appropriately powered noninferiority studies according to NCCN risk groups. We eagerly await the completion and reporting of such trials so that we have a more personalized approach to treating men with prostate cancer.”

The current study was funded by Myriad Genetics, the company that developed the Prolaris test. Dr. Tward disclosed relationships with Myriad Genetics, Bayer, Blue Earth Diagnostics, Janssen Scientific Affairs, and Merck. Dr. Valicenti has no disclosures.

The Food and Drug Administration has approved cemiplimab-rwlc (Libtayo) as the first immunotherapy to treat patients with locally advanced or metastatic basal cell carcinoma (BCC) previously treated with a hedgehog pathway inhibitor or in whom an HHI is inappropriate.

The FDA granted full approval for the locally advanced BCC indication and accelerated approval for the metastatic BCC indication, according to a press release from Regeneron and Sanofi, the companies jointly developing cemiplimab.

Cemiplimab is a programmed death–1 inhibitor that was first FDA approved in 2018 for locally advanced or metastatic cutaneous squamous cell carcinoma not eligible for curative surgery or radiation.

The new approval “will change the treatment paradigm for patients with advanced basal cell carcinoma,” according to Karl Lewis, MD, a professor at the University of Colorado at Denver, Aurora, and an investigator on the phase 2 trial of cemiplimab.

“While the primary systemic treatment options are hedgehog inhibitors, many patients will eventually progress on or become intolerant to this therapy,” Dr. Lewis said in the press release. “With Libtayo [cemiplimab], these patients now have a new immunotherapy option.”

The approval of cemiplimab in BCC was based on an open-label, phase 2 trial of 132 patients with advanced BCC. Patients could not tolerate, had progressed on, or had not responded to HHIs after 9 months of treatment.

Cemiplimab was given at 350 mg every 3 weeks. The study was not placebo controlled and has not been published, a Regeneron spokesperson said.

There were 112 patients in the efficacy analysis. The overall response rate was 21% (6/28) in metastatic BCC patients, with no complete responders. In locally advanced BCC patients, the objective response rate was 29% (24/84), with five complete responders.

The median duration of response was not reached in either group but was at least 6 months long in all metastatic patients and in 79% (19/84) of the locally advanced BCC patients.

The most common adverse events among the 132 subjects evaluable for safety were fatigue (49%), musculoskeletal pain (33%), diarrhea (25%), rash (22%), pruritus (20%), and upper respiratory tract infection (15%).

Serious adverse events occurred in 32% of patients, including colitis, acute kidney injury, adrenal insufficiency, and anemia. Adverse events led to discontinuation in 13% of patients, most often for colitis and general physical health deterioration.

For now at least, total body irradiation (TBI) plus etoposide remains the conditioning regimen of choice for children undergoing allogeneic hematopoietic stem cell transplant for acute lymphoblastic leukemia (ALL), according to an open-label, phase 3 trial from Europe.

The investigators sought to answer a question many physicians have raised: With improvements in human leukocyte antigen typing, better graft-versus-host disease prophylaxis, and other advances, can myeloablative chemotherapy conditioning replace TBI, which is more toxic?

The downstream effects of TBI can include secondary malignancies and cataracts, as well as impaired growth and impaired gonadal and cognitive function.

But the answer to that question is no, or at least, not yet.

The phase 3 trial included individuals with ALL who were aged 4-21 years at time of transplant. They were randomly assigned to receive either fractionated TBI at 12 Gy plus etoposide or chemotherapy based on a myeloablative regimen: fludarabine, thiotepa, and either busulfan or treosulfan.

The trial was stopped after 413 patients had undergone randomization – quite a bit short of the 1,000-patient goal. The trial was terminated because TBI proved clearly superior on an interim analysis at a median follow-up of 2.1 years.

The results showed that 72% of the TBI group – but only 51% of the chemotherapy arm – were relapse free at 2 years with no graft-versus-host disease (P = .0003).

The 2-year treatment-related mortality rate was 2% in the TBI group but 9% with chemotherapy conditioning (P = .03).

The study was published Feb. 1, 2020, in the Journal of Clinical Oncology.

“We recommend TBI plus etoposide conditioning for patients [aged over] 4 years old with high-risk ALL undergoing allogeneic HSCT [hematopoietic stem cell transplant],” they concluded. The investigators were led by Christina Peters, MD, a pediatrics professor at the St. Anna Children’s Cancer Research Institute, Vienna.

The benefits of TBI held on multivariate analysis and across subgroups, including children in their first and second remissions and among those with high-risk cytogenetics. Relapse risk factors, such as age at transplant, leukemic phenotype, and molecular aberrations, did not significantly affect outcomes, the authors reported.

Given that relapses plateaued with TBI at 2.5 years but were still on the upswing for patients who underwent chemoconditioning, “it is unlikely that secondary malignancies after TBI could jeopardize the survival advantage,” they wrote.

“So does this mean that the HCT community is forever chained to TBI as a standard of care? Certainly, it means that without very sound rationale to deviate, a TBI-based preparative regimen is the preferred therapy at present,” Michael Pulsipher, MD, head of blood and marrow transplantation at Children’s Hospital Los Angeles, commented in an accompanying editorial.

However, “there are approaches under study currently that may define patients who do not need TBI for high rates of cure,” he suggested. Those approaches include selecting patients with the deepest remissions and using KIR-favorable haplotype to harness natural killer cell activity.

“In our new world of chimeric antigen receptor T-cells and immunotherapies, surely we can find safer paths to success,” Dr. Pulsipher wrote.

With regard to patient selection, the investigators noted that a recent review that included more than 3,000 children with ALL found no overall survival benefit with TBI versus chemoconditioning for patients in first complete remission but worse outcomes with chemoconditioning among patients in second complete remission. “A similar trend was observed in our subgroup analyses; however, our study was not powered to assess statistical significance in a sample size of 413 patients,” they wrote.

Minimal residual disease did not influence survival outcomes, probably because the investigators were aggressive in inducing deep remission in their patients before transplant, so for most patients, MRD was undetectable or very low beforehand.

The study was funded by Amgen, Jazz Pharmaceuticals, Neovii, Medac, and others. Dr. Peters and coauthors, as well as Dr. Pulsipher have disclosed numerous ties with those and/or other companies.

An investigational elastography technique for evaluating thyroid nodules while individuals use their voice could improve the detection of malignant tumors, which are sometimes missed by ultrasound and fine-needle aspiration biopsy, say French researchers. However, it has not yet been tested for cancer detection.

The new approach involves holding a linear ultrasound probe to the throat of the patient, who is then requested to vocalize an “eee” sound at 150 Hz. A loudspeaker plays a 150-Hz sound to guide the patient.

The vocal vibrations generated, called shear waves, are detected by the probe as they pass through the thyroid. Software the researchers developed calculates the velocity of the shear waves, which move faster through stiffer tissue. The software produces a stiffness map that is then superimposed onto a gray-scale (B mode) thyroid image from the ultrasound.

Cancerous tissue is stiffer than healthy tissue and benign nodules, so shear waves pass through it more quickly, the researchers explained. Areas of particular stiffness that are revealed by the test are a concern.

The study was published online Jan. 12 in Applied Physics Letters.

The new approach is a noninvasive method that “would reduce the stress of patients during their medical exams. Having to sing during a medical exam can perhaps help release some of the nervous tension even more,” lead investigator Steve Beuve, PhD, of the Université de Tours (France), said in a press release. The main benefit of this technique is that it is “quick and easy,” he added. Data acquisition takes about a second, and no specialized equipment is required. Imaging can be rendered by any Doppler ultrasound set at an ultrafast frame rate to track the shear waves. The computer program automatically calculates wave velocity through various parts of the thyroid.

The technique, dubbed vocal passive elastography (VPE), has not yet been tested to see how well it distinguishes cancerous from benign thyroid nodules.

“We want to cooperate with physicians to propose protocols to verify [VPE’s] relevance,” Dr. Beuve said.

Because no data are currently available on how accurate VPE is in diagnosing malignant nodules, it is not possible to comment on its potential usefulness, Aya Kamaya, MD, a radiology professor at Stanford (Calif.) University Medical Center, said in an interview.

Ultrasound elastography for diagnosing thyroid disease has been in development for years. More than 100 reports have been published in the medical literature since 2005. Various devices are available commercially, but for now, elastography for thyroid nodules remains investigational, she said.

Another expert who was approached for comment was more critical.

Lisa Orloff, MD, a professor and director of endocrine head and neck surgery and the thyroid tumor program at Stanford University, noted that, in general, “elastography has not gained more traction in thyroid evaluation to date because it does not appear to reduce the need for [fine-needle aspiration] of suspicious nodules based on gray-scale ultrasound alone, without elastography.”

As for the French report, she said that “while the voice might be a convenient shear wave source, I am very skeptical at many levels. I get the impression that [this is] a laboratory-based concept that is fraught with confounding factors in attempting real-world application.

“One concern is that the thyroid gland and nodule stiffness are affected by factors including underlying goiter, autoimmune disease, fluid content of nodules, calcifications, and other variables that can be present in benign or malignant conditions. And there are so many variables that would affect an individual patient’s ability (or not) to phonate at 150 Hz,” Dr. Orloff said.

VPE is an extension of passive elastography, which extracts elasticity data from the natural vibrations caused by the heart, blood pulsatility, and muscle activity, the authors explained. The team turned to vocalization at 150 Hz in part to overcome the physiological background noise in the thyroid from carotid pulsation at about 1-10 Hz.

The group is exploring vocalizations at other frequencies and is working to improve the computer program interface. They are also exploring VPE for other organs, including the brain.

The source of funding for the study and the authors’ relevant financial relationships were not reported.

Lisa Orloff, MD, a professor and director of endocrine head and neck surgery and the thyroid tumor program at Stanford University, noted that, in general, “elastography has not gained more traction in thyroid evaluation to date because it does not appear to reduce the need for [fine-needle aspiration] of suspicious nodules based on gray-scale ultrasound alone, without elastography.”

As for the French report, she said that “while the voice might be a convenient shear wave source, I am very skeptical at many levels. I get the impression that [this is] a laboratory-based concept that is fraught with confounding factors in attempting real-world application.

“One concern is that the thyroid gland and nodule stiffness are affected by factors including underlying goiter, autoimmune disease, fluid content of nodules, calcifications, and other variables that can be present in benign or malignant conditions. And there are so many variables that would affect an individual patient’s ability (or not) to phonate at 150 Hz,” Dr. Orloff said.

VPE is an extension of passive elastography, which extracts elasticity data from the natural vibrations caused by the heart, blood pulsatility, and muscle activity, the authors explained. The team turned to vocalization at 150 Hz in part to overcome the physiological background noise in the thyroid from carotid pulsation at about 1-10 Hz.

The group is exploring vocalizations at other frequencies and is working to improve the computer program interface. They are also exploring VPE for other organs, including the brain.

The source of funding for the study and the authors’ relevant financial relationships were not reported.

It’s been shown that hospitalized cancer patients and those undergoing active treatment are at high risk for severe COVID-19 complications. A new study shows that patients with cancer in remission are at higher risk, too.

For the study, investigators from the University of Pennsylvania, Philadelphia, analyzed 323 patients with SARS-CoV-2 infection in a research database with more than 4,800 patients. About 20% of database patients were Black, but they accounted for almost 65% of the infections, reflecting previous reports of increased risk for COVID among Black people.

A total of 67 of the infected patients had cancer, including 18 patients with active cancer and 49 patients whose cancer was in remission. After adjusting for demographics, smoking status, and comorbidities, a diagnosis of cancer more than doubled the odds of hospitalization and increased the odds of 30-day mortality nearly sixfold.

Worse outcomes were more strongly associated with active cancer, but patients whose cancer was in remission were also at higher risk than patients who did not have cancer.

It’s not only “patients hospitalized or on treatment ... all oncology patients need to take significant precautions during the pandemic to protect themselves,” senior investigator Kara Maxwell, MD, PhD, hematologist/oncologist and assistant professor at the University of Pennsylvania, said in a press release.

The study was published online on Jan. 21 in JNCI Cancer Spectrum.

The good news is that steps to prevent SARS-CoV-2 infection work, suggests a second report from the University of Pennsylvania. Among 124 cancer patients who underwent outpatient infusions from May to October 2020, not a single one experienced seroconversion over a median of 13 clinical visits. That second study was published on Jan. 16 in medRxiv and is pending peer review.

The zero seroconversion rate likely reflects “the success of transmission mitigation measures within health care facilities,” wrote investigators led by Lova Sun, MD, a hematology/oncology fellow at the University of Pennsylvania.

Like many institutions, the University of Pennsylvania Health System (Penn Medicine) is aggressive in protecting outpatients against the virus, the authors wrote. Among other steps, patients are queried about symptoms and contacts before their office visit, and their temperature is taken when they come in. Masks are worn, check-in is contactless, the number of visitors is limited, and patients who test positive are treated in a separate space.

In addition, patients in the study also reported that they wore masks and practiced social distancing in their daily lives.

Approached for comment, hematologist/oncologist Charles Shapiro, MD, a professor at the Icahn School of Medicine at Mount Sinai and director of translational breast cancer research at Mount Sinai Hospital, both in New York, said he wasn’t surprised that the prevention measures followed at Penn Medicine work. They are very similar to the measures followed at Mount Sinai oncology clinics, and “there’ve been very few COVID cases in our shop,” he added.

The bigger take-home message from both studies is that cancer patients, regardless of their age or if they are in remission, should be prioritized for vaccination against COVID-19, which is the best way to mitigate risk. “I strongly urge my patients to get it” if they can, he said.

The problem in New York is that immunizations are largely limited to people aged 65 years and older. Younger cancer patients are left out, and access has been spotty for all patients. “Vaccine is available one day, then not the next. It’s disheartening,” Dr. Shapiro said in an interview. “Hopefully, with the new administration, this will smooth out,” and the age limit will drop.

The study was supported by the National Institutes of Health, among other organizations. Dr. Lova, Dr. Maxwell, and Dr. Shapiro have disclosed no relevant financial relationships.

A new tool for predicting the risk of severe chemotherapy toxicity in older adults with early-stage breast cancer outperforms existing models and should help older patients and physicians make treatment decisions with more confidence, according to investigators.

They devised and tested the tool, called the Cancer and Aging Research Group–Breast Cancer (CARG-BC) score, in two cohorts of patients aged 65 years or older with stage I-III breast cancer.

The area under the curve for predicting grade 3-5 toxicity was 0.75 in the development cohort and 0.69 in the validation cohort, for a combined AUC of 0.73.

The CARG-BC score outperformed both Karnofsky performance status (AUC, 0.50) and the Cancer and Aging Research Group Chemotherapy Toxicity Tool (AUC, 0.56).

CARG-BC risk groups were also associated with hospitalizations, dose modifications, and early termination of treatment.

Allison Magnuson, DO, of the University of Rochester (N.Y.), and colleagues described these results in the Journal of Clinical Oncology.
 

About CARG-BC

To calculate a patient’s CARG-BC score, the researchers added up points assigned to eight independent predictors of grade 3-5 chemotherapy toxicity:

• Planned anthracycline use (1 point)
• Stage II or III disease (3 points)
• Planned treatment duration longer than 3 months (4 points)
• Abnormal liver function (3 points)
• Low hemoglobin level (3 points)
• A fall in the previous 6 months (4 points)
• Limited ability to walk more than 1 mile (3 points)
• Lack of social support (3 points)

Patients with scores of 0-5 have a low risk, those with scores of 6-11 have an intermediate risk, and those with scores of 12 or above have a high risk of grade 3-5 toxicity.
 

Patient characteristics and results

There were 283 patients in the development cohort and 190 in the validation cohort. There were no significant demographic, disease, or treatment differences between the cohorts.

All patients had a mean age of 70.5 years, 36.2% had stage I disease, 42.9% had stage II, and 20.9% had stage III disease. Three-quarters of patients were non-Hispanic White, and 99.4% were women. Roughly a third of patients had received an anthracycline-based regimen.

Overall, about a quarter of patients had an unplanned dose reduction (24%), dose delay (26%), stopped treatment early (24%), or were hospitalized during treatment (23%). All of these occurrences were more likely in intermediate- and high-risk patients versus low-risk patients (P < .001).

In the development cohort, 19% of low-risk patients, 54% of intermediate-risk patients, and 87% of high-risk patients developed grade 3-5 chemotherapy toxicity.

Compared with the 93 patients in the low-risk group, the odds of toxicity was almost 5 times greater for the 159 intermediate-risk subjects, and 28 times greater for the 30 high-risk subjects.

In the validation cohort, grade 3-5 toxicity rates were 27% in the low-risk group, 45% in the intermediate-risk group, and 76% in the high-risk group.

This study had its limitations, including that a majority of subjects (72.2%) had a college education, and the validation cohort was accrued from the same 16 institutions as the development cohort.

“Further validation in a more diverse population should be considered,” the investigators wrote.
 

A ‘useful’ tool for guiding therapy

The investigators noted that chemotherapy is a complex decision for older adults with stage I-III breast cancer. While it may be indicated, chemotherapy is underused often because of the higher risk of severe toxicity in older people.

“Unfortunately, older adults aged 65 and over, who comprise about half of all breast cancer diagnoses, are significantly less likely to be offered chemotherapy compared to younger patients – sometimes because their doctors fear they won’t be able to tolerate it,” investigator Mina Sedrak, MD, of City of Hope National Medical Center in Duarte, Calif., said in a press release.

The CARG-BC score may be useful to direct therapy in older adults with early-stage breast cancer, the investigators wrote. They noted that intensifying supportive care and developing modified treatment regimens may be appropriate for patients at higher risk for toxicity.

“Although this score should not be used as the only factor in deciding whether to administer and/or alter the dose or schedule of chemotherapy, the CARG-BC score can be used to facilitate this complex decision-making process, along with clinical judgment and patient preferences,” they wrote.

“I think this is a great tool. [It] will be helpful to me to have a more accurate conversation with geriatric patients about the actual risk/benefit ratio for chemotherapy in early breast cancer,” said Amy Tiersten, MD, of Mount Sinai Hospital in New York, when asked for comment.

“If routinely implemented, it may help reduce age bias and also identify older patients who may look well but may be vulnerable and quickly decompensate while undergoing treatment,” said Lidia Schapira, MD, of Stanford (Calif.) University. “Importantly, it can be used to guide conversations about trade-offs and to start a frank conversation about an older patient’s fears and concerns about treatment.”

This research was funded by the National Institute on Aging, the Breast Cancer Research Foundation, and the Center for Cancer and Aging at City of Hope. The investigators, Dr. Schapira, and Dr. Tiersten had no relevant disclosures.

In contrast to what has been seen in other tumor types, recurrent glioblastoma (rGBM) may respond better to immunotherapy when tumor mutational burden (TMB) is low, new research suggests.

There’s an “unexpected correlation between TMB, tumor-intrinsic inflammation, and survival after immunotherapy” in this patient population, researchers noted in a Nature Communications report.

Cases of rGBM in which TMB is low are more likely to respond to immunotherapy than cases in which TMB is higher, the investigators concluded from an analysis of tumor tissue from more than 100 patients.

“We need to do a prospective study and establish a threshold in a particular assay format,” senior author David Ashley, MBBS, PhD, a neurosurgery professor at Duke University, Durham, N.C., said in an interview.

Andrew Sloan, MD, a neurosurgery professor at the Seidman Cancer Center, Cleveland, said in a comment that “many have given up on immunotherapy for GBM because these tumors tend to have lower TMB than tumors that typically respond to immunotherapy, including checkpoint inhibitors.” (Examples include melanoma and lung cancer.)

“If the findings are confirmed, it would be very useful clinically to select” patients for immunotherapy, Dr. Sloan commented.
 

Correlation seen with rGBM, not primary tumor

Recurrence of GBM is almost inevitable, even when aggressive standard-of-care therapy is given initially, according to Dr. Ashley and colleagues. Studies have indicated that, in 10%-20% of patients with rGBM, disease responds to subsequent immunotherapy, and patients live beyond the predicted median survival of about 12 months. It’s been unclear, however, what distinguishes these survivors from the other patients.

Dr. Ashley and colleagues looked for common genetic factors that distinguish survivors.

The tumor tissue the team analyzed came from three studies. The first was a trial of an intratumoral infusion of a recombinant nonpathogenic poliorhinovirus chimera (PVSRIPO), developed at Duke University, that induces innate inflammation and T-cell attack. Among 61 patients, 21% were alive at 3 years versus 4% of historical control patients.

The second study was a review of 66 patients with GBM who underwent treatment with pembrolizumab or nivolumab. The median survival was 14.3 months among those who experienced a response versus10.1 months for those who did not.

The third study involved more than 1,000 patients with advanced cancer who underwent treatment with checkpoint inhibitors. There was no survival benefit among the 117 patients with glioma who were treated with checkpoint inhibitors.

In the PVSRIPO trial, rGBM tumors from patients who survived longer than 20 months harbored very low TMB, less than 0.6 mutations/Mb. In the two checkpoint inhibitor trials, among 110 patients with rGBM, survival was longer for those whose TMB was at or below the median level.

The differences in survival were not driven by differences in steroid dosing, unfavorable responses among patients with hypermutations, or the presence or absence of IDH1 or PTEN mutations or MGMT promoter methylation, according to Dr. Ashley and colleagues.

“Increased survival of immunotherapy-treated rGBM patients with very low TMB is due to immunotherapy response,” the investigators concluded.

As for the explanation, the team found that rGBM tumors with lower TMB levels had enriched inflammatory gene signatures, compared with tumors with higher TMB levels.

The correlation – and longer survival with low TMB – was not observed in primary GBM tumors, “indicating that a relationship between tumor-intrinsic inflammation and TMB develops upon recurrence. ... We postulate that the baseline inflammatory status of rGBM tumors determines their susceptibility to immunotherapy,” the authors wrote.

Because the correlation between tumor inflammation and TMB was robust in rGBM but not in primary tumors, it might well have been caused by standard-of-care therapy, which affects mutation levels.

“Chemotherapy, which is the standard of care for newly diagnosed glioblastoma, might be altering the inflammatory response in these tumors” and priming an inflammatory process that increases vulnerability to immunotherapy in recurrent tumors, Dr. Ashley said in a press release.

Shorter time to recurrence also correlated with lower TMB and favorable response to PVSRIPO, so shorter duration of standard therapy or shorter time from initial surgery might improve immunotherapy response, he speculated.

The study was funded by the National Institutes of Health and other organizations. Dr. Ashley and other investigators own intellectual property related to PVSRIPO, which has been licensed to Istari Oncology. Several investigators hold equity in and/or are paid consultants for Istari. Dr. Sloan is the Ohio principal investigator for an rGBM PVSRIPO and pembrolizumab study funded by the company.

Andrew Sloan, MD, a neurosurgery professor at the Seidman Cancer Center, Cleveland, said in a comment that “many have given up on immunotherapy for GBM because these tumors tend to have lower TMB than tumors that typically respond to immunotherapy, including checkpoint inhibitors.” (Examples include melanoma and lung cancer.)

“If the findings are confirmed, it would be very useful clinically to select” patients for immunotherapy, Dr. Sloan commented.
 

Correlation seen with rGBM, not primary tumor

Recurrence of GBM is almost inevitable, even when aggressive standard-of-care therapy is given initially, according to Dr. Ashley and colleagues. Studies have indicated that, in 10%-20% of patients with rGBM, disease responds to subsequent immunotherapy, and patients live beyond the predicted median survival of about 12 months. It’s been unclear, however, what distinguishes these survivors from the other patients.

Dr. Ashley and colleagues looked for common genetic factors that distinguish survivors.

The tumor tissue the team analyzed came from three studies. The first was a trial of an intratumoral infusion of a recombinant nonpathogenic poliorhinovirus chimera (PVSRIPO), developed at Duke University, that induces innate inflammation and T-cell attack. Among 61 patients, 21% were alive at 3 years versus 4% of historical control patients.

The second study was a review of 66 patients with GBM who underwent treatment with pembrolizumab or nivolumab. The median survival was 14.3 months among those who experienced a response versus10.1 months for those who did not.

The third study involved more than 1,000 patients with advanced cancer who underwent treatment with checkpoint inhibitors. There was no survival benefit among the 117 patients with glioma who were treated with checkpoint inhibitors.

In the PVSRIPO trial, rGBM tumors from patients who survived longer than 20 months harbored very low TMB, less than 0.6 mutations/Mb. In the two checkpoint inhibitor trials, among 110 patients with rGBM, survival was longer for those whose TMB was at or below the median level.

The differences in survival were not driven by differences in steroid dosing, unfavorable responses among patients with hypermutations, or the presence or absence of IDH1 or PTEN mutations or MGMT promoter methylation, according to Dr. Ashley and colleagues.

“Increased survival of immunotherapy-treated rGBM patients with very low TMB is due to immunotherapy response,” the investigators concluded.

As for the explanation, the team found that rGBM tumors with lower TMB levels had enriched inflammatory gene signatures, compared with tumors with higher TMB levels.

The correlation – and longer survival with low TMB – was not observed in primary GBM tumors, “indicating that a relationship between tumor-intrinsic inflammation and TMB develops upon recurrence. ... We postulate that the baseline inflammatory status of rGBM tumors determines their susceptibility to immunotherapy,” the authors wrote.

Because the correlation between tumor inflammation and TMB was robust in rGBM but not in primary tumors, it might well have been caused by standard-of-care therapy, which affects mutation levels.

“Chemotherapy, which is the standard of care for newly diagnosed glioblastoma, might be altering the inflammatory response in these tumors” and priming an inflammatory process that increases vulnerability to immunotherapy in recurrent tumors, Dr. Ashley said in a press release.

Shorter time to recurrence also correlated with lower TMB and favorable response to PVSRIPO, so shorter duration of standard therapy or shorter time from initial surgery might improve immunotherapy response, he speculated.

The study was funded by the National Institutes of Health and other organizations. Dr. Ashley and other investigators own intellectual property related to PVSRIPO, which has been licensed to Istari Oncology. Several investigators hold equity in and/or are paid consultants for Istari. Dr. Sloan is the Ohio principal investigator for an rGBM PVSRIPO and pembrolizumab study funded by the company.

In contrast to what has been seen in other tumor types, recurrent glioblastoma (rGBM) may respond better to immunotherapy when tumor mutational burden (TMB) is low, new research suggests.

There’s an “unexpected correlation between TMB, tumor-intrinsic inflammation, and survival after immunotherapy” in this patient population, researchers noted in a Nature Communications report.

Cases of rGBM in which TMB is low are more likely to respond to immunotherapy than cases in which TMB is higher, the investigators concluded from an analysis of tumor tissue from more than 100 patients.

Use of linked-color imaging for upper gastrointestinal tract endoscopy improves the detection of neoplasms in comparison with conventional white-light imaging, according to results from a randomized trial involving more than 1,500 patients.

Linked-color imaging (LCI) is an advanced illumination technique that combines white light with narrow-band short-wavelength light to enhance the contrast of red and white hues during endoscopy, making it easier to recognize subtle differences in mucosal color.

At present, LCI is available only on systems manufactured by Fujifilm (that is, the Lasereo endoscopic system marketed in Japan and the Eluxeo system in the United States and Europe). The system includes the light source and a processor and can be used with various endoscopes.

“Combined with previous studies that show the efficacy of LCI in detecting large intestinal neoplasia, our findings make a strong case for wider adoption of this modality in surveillance of the entire endoscopically accessible digestive tract,” senior investigator and gastroenterologist Mototsugu Kato, MD, of the Hakodate National Hospital, Hokkaido, Japan, said in a press release.

The randomized trial was conducted at 19 Japanese hospitals by 58 expert endoscopists, all of whom were experienced with LCI.

“We need further research to confirm [LCI’s] efficacy in the hands of general clinicians for upper GI screening” of an average-risk population, Dr. Kato said.

Results from the trial were published in Annals of Internal Medicine.

Approached for comment, gastroenterologist Marvin Ryou, MD, director of endoscopic innovation at Brigham and Women’s Hospital, Boston, said that he has used Fujifilm’s LCI technology mostly for polyp detection on colonoscopy and has found it useful.

LCI “has been shown to be helpful for the detection of colonic neoplasia, and this Japanese multicenter study provides additional evidence of utility in foregut neoplasm detection. I would look forward to future studies of LCI in an average-risk population,” he said.
 

Details of the randomized trial

All of the trial participants had previous or current gastrointestinal cancer and were undergoing upper GI endoscopic surveillance. Patients were a little older than 70 years on average, and more than 75% were men.

The patients underwent two examinations during their endoscopy sessions, one performed with LCI, and the other with conventional white-light imaging (WLI). The endoscopy system used in the study allowed the scope to switch between the two modalities, as well as others.

Overall, 750 patients were randomly assigned to undergo LCI first and then WLI; 752 underwent WLI first and then LCI.

In both groups, lesions were most common in the stomach, followed by the esophagus and the pharynx.

Neoplastic lesions in the pharynx, esophagus, or stomach – confirmed by histology – were detected in 60 patients (8%) with LCI versus 36 patients (4.8%) with WLI. This translated to a 1.67 times higher rate of detection.

First-pass WLI missed 26 lesions that were picked up by second-pass LCI. Five lesions were missed by LCI and were subsequently detected by WLI, which translated to a greater than 80% reduction in missed lesions with LCI.

Procedure time was longer with LCI than WLI, but mean differences were less than 20 seconds.

The investigators said that there is a possibility of overdiagnosis with both systems, but perhaps more so with LCI. Overall, WLI detected 121 lesions on first pass, 30.6% of which were neoplastic; first-pass LCI detected 185 lesions, 35.7% of which were neoplastic.

The trial was funded by Fujifilm. One investigator has received a grant and another has received research funding from Fujifilm. Dr. Ryou is a consultant for the company.
