As many as 40% of lumpectomies leave positive margins that necessitate a second surgery, but a novel fluorescent imaging agent used along with a direct visualization system may improve complete resection rates, new phase 3 findings show.

Pegulicianine (Lumisight), an investigational and activatable fluorescent imaging agent used with a novel direct visualization system, helped identify residual tumor or circumvent second surgeries in about 10% of patients in the trial.

Use of the agent and direct visualization system – both from Lumicell and currently under review by the Food and Drug Administration – could provide more complete resection for patients with early breast cancer and avert the need for reexcisions, the investigators write.

The findings were published online in NEJM Evidence and were subsequently presented at the annual meeting of the American Society of Breast Surgeons.

Local recurrence following lumpectomy increases the risk of dying from breast cancer, and the risk of local recurrence is directly linked to inadequate tumor removal during lumpectomy. In about 20%-40% of lumpectomies, positive margins are identified after surgery.

To improve patient outcomes, investigators assessed whether a novel fluorescence-guided surgery system helped surgeons perform more complete resections during lumpectomy.

In the Novel Surgical Imaging for Tumor Excision (INSITE) trial, 392 patients were randomly assigned to undergo pegulicianine fluorescence-guided surgery (n = 357) or standard lumpectomy (n = 35).

To prevent surgeons from performing a smaller than standard lumpectomy in anticipation of using the pegulicianine fluorescence-guided system, patients were randomly assigned to the pegulicianine fluorescence-guided surgery group or the control group. The groups were revealed only after the surgeon completed the standard lumpectomy.

“Randomization was not designed to provide a control group for analysis of device performance,” The authors explain. “In this study design, each patient undergoing pegulicianine fluorescence-guided surgery served as her own control,” they write. The investigators compared final margin pathology after standard lumpectomy and after guided surgery. Those in the control group were included in the safety analysis.

Study participants were women aged 18 years or older who were undergoing lumpectomy for stage I–III breast cancer and/or ductal carcinoma in situ. All patients received pegulicianine 1.0 mg/kg via a 3-minute intravenous infusion 2-6 hours before surgery.

The agent produces a signal at sites of residual tumor, and a handheld probe illuminates the cavity during surgery. A tumor detection algorithm then analyzes and displays the images to the surgeon in real time – an overall process that adds about 7 minutes to the operative procedure, the authors say.

Investigators identified invasive cancers in 316 patients and in situ cancers in 76 patients. Among the 357 patients in the treatment group, 27 (7.6%) were found to have residual tumor after standard lumpectomy. For 22 patients, cavity orientations were deemed negative on standard margin evaluations, the authors report.

With use of pegulicianine fluorescence-guided surgery, positive margins were converted to negative margins for 9 of 62 patients (14.5%), potentially averting a second surgery in those patients.

Overall, the authors say that pegulicianine fluorescence-guided surgery removed residual tumor (27 of 357) or avoided second surgeries (9 of 357) in 10% of patients in the trial.

The current trial findings confirm results regarding the safety and efficacy of pegulicianine fluorescence-guided surgery and the direct visualization system that were reported in a prior multicenter feasibility study, the authors say.

Pegulicianine fluorescence-guided surgery met prespecified thresholds for removal of residual tumor and specificity, at 85.2%, but did not meet the prespecified threshold for sensitivity, which was only 49.3%.

The rate of serious adverse events with pegulicianine was 0.5% (two patients), similar to that of other contrast agents. Administration of the agent was stopped because of adverse events for six patients, the investigators write.

Serious adverse events included grade 3 hypersensitivity in one patient and an anaphylactic reaction in another. The other four adverse events included an allergic reaction, milder hypersensitivity, nausea, and pegulicianine extravasation. All adverse events resolved, and patients proceeded to standard lumpectomy.

Overall, the trial findings “suggest that a more complete breast cancer resection may be achieved” with pegulicianine fluorescence-guided surgery and the direct visualization system, lead investigator Barbara Smith, MD, PhD, director of the breast program at Massachusetts General Hospital and professor of surgery at Harvard Medical School, both in Boston, said in a press release. “Given the low complication rate, minimal added operative time and, most importantly, the discovery of additional cancer left behind after a lumpectomy, the Lumicell [system] has the potential to be a critical adjunct to enhance standard practice for breast cancer patients.”

The system also has the potential to reduce “the patient burden of additional surgery” and decrease “costs associated with a return to the operating room,” the authors conclude.

The INSITE trial was funded by Lumicell and the National Institutes of Health. Dr. Smith reported unpaid research collaboration with Lumicell.

Communities with easy access to fast food were 77% more likely to have high levels of obesity-related cancer mortality, based on data from a new cross-sectional study of more than 3,000 communities.

Although increased healthy eating has been associated with reduced risk of obesity and with reduced cancer incidence and mortality, access to healthier eating remains a challenge in communities with less access to grocery stores and healthy food options (food deserts) and/or easy access to convenience stores and fast food (food swamps), Malcolm Seth Bevel, PhD, of the Medical College of Georgia, Augusta, and colleagues, wrote in their paper, published in JAMA Oncology.

In addition, data on the association between food deserts and swamps and obesity-related cancer mortality are limited, they said.

“We felt that the study was important given the fact that obesity is an epidemic in the United States, and multiple factors contribute to obesity, especially adverse food environments,” Dr. Bevel said in an interview. “Also, I lived in these areas my whole life, and saw how it affected underserved populations. There was a story that needed to be told, so we’re telling it,” he said in an interview.

In a study, the researchers analyzed food access and cancer mortality data from 3,038 counties across the United States. The food access data came from the U.S. Department of Agriculture Food Environment Atlas (FEA) for the years 2012, 2014, 2015, 2017, and 2020. Data on obesity-related cancer mortality came from the Centers for Disease Control and Prevention for the years from 2010 to 2020.

Food desert scores were calculated through data from the FEA, and food swamp scores were based on the ratio of fast-food restaurants and convenience stores to grocery stores and farmers markets in a modification of the Retail Food Environment Index score.

The researchers used an age-adjusted, multiple regression model to determine the association between food desert and food swamp scores and obesity-related cancer mortality rates. Higher food swamp and food desert scores (defined as 20.0 to 58.0 or higher) were used to classify counties as having fewer healthy food resources. The primary outcome was obesity-related cancer mortality, defined as high or low (71.8 or higher per 100,000 individuals and less than 71.8 per 100,000 individuals, respectively).

Overall, high rates of obesity-related cancer mortality were 77% more likely in the counties that met the criteria for high food swamp scores (adjusted odds ratio 1.77). In addition, researchers found a positive dose-response relationship among three levels of both food desert scores and food swamp scores and obesity-related cancer mortality.

A total of 758 counties had obesity-related cancer mortality rates in the highest quartile. Compared to counties with low rates of obesity-related cancer mortality, counties with high rates of obesity-related cancer mortality also had a higher percentage of non-Hispanic Black residents (3.26% vs. 1.77%), higher percentage of adults older than 65 years (15.71% vs. 15.40%), higher rates of adult obesity (33.0% vs. 32.10%), and higher rates of adult diabetes (12.50% vs. 10.70%).

Possible explanations for the results include the lack of interest in grocery stores in neighborhoods with a population with a lower socioeconomic status, which can create a food desert, the researchers wrote in their discussion. “Coupled with the increasing growth rate of fast-food restaurants in recent years and the intentional advertisement of unhealthy foods in urban neighborhoods with [people of lower income], the food desert may transform into a food swamp,” they said.

The findings were limited by several factors including the study design, which did not allow for showing a causal association of food deserts and food swamps with obesity-related cancer mortality, the researchers noted. Other limitations included the use of groups rather than individuals, the potential misclassification of food stores, and the use of county-level data on race, ethnicity, and income, they wrote.

The results indicate that “food swamps appear to be a growing epidemic across the U.S., likely because of systemic issues, and should draw concern and conversation from local and state officials,” the researchers concluded.
 

Community-level investments can benefit individual health

Dr. Bevel said he was not surprised by the findings, as he has seen firsthand the lack of healthy food options and growth of unhealthy food options, especially for certain populations in certain communities. “Typically, these are people who have lower socioeconomic status, primarily non-Hispanic Black or African American or Hispanic American,” he said “I have watched people have to choose between getting fruits/vegetables versus their medications or running to fast food places to feed their families. What is truly surprising is that we’re not talking about people’s lived environment enough for my taste,” he said.  

“I hope that our data and results can inform local and state policymakers to truly invest in all communities, such as funding for community gardens, and realize that adverse food environments, including the barriers in navigating these environments, have significant consequences on real people,” said Dr. Bevel. “Also, I hope that the results can help clinicians realize that a patient’s lived environment can truly affect their obesity and/or obesity-related cancer status; being cognizant of that is the first step in holistic, comprehensive care,” he said. 

“One role that oncologists might be able to play in improving patients’ access to healthier food is to create and/or implement healthy lifestyle programs with gardening components to combat the poorest food environments that their patients likely reside in,” said Dr. Bevel. Clinicians also could consider the innovative approach of “food prescriptions” to help reduce the effects of deprived, built environments, he noted.

Looking ahead, next steps for research include determining the severity of association between food swamps and obesity-related cancer by varying factors such as cancer type, and examining any potential racial disparities between people living in these environments and obesity-related cancer, Dr. Bevel added.
 

Data provide foundation for multilevel interventions

The current study findings “raise a clarion call to elevate the discussion on food availability and access to ensure an equitable emphasis on both the importance of lifestyle factors and the upstream structural, economic, and environmental contexts that shape these behaviors at the individual level,” Karriem S. Watson, DHSc, MS, MPH, of the National Institutes of Health, Bethesda, Md., and Angela Odoms-Young, PhD, of Cornell University, Ithaca, N.Y., wrote in an accompanying editorial.

The findings provide a foundation for studies of obesity-related cancer outcomes that take the community environment into consideration, they added.

The causes of both obesity and cancer are complex, and the study findings suggest that the links between unhealthy food environments and obesity-related cancer may go beyond dietary consumption alone and extend to social and psychological factors, the editorialists noted.

“Whether dealing with the lack of access to healthy foods or an overabundance of unhealthy food, there is a critical need to develop additional research that explores the associations between obesity-related cancer mortality and food inequities,” they concluded.

The study received no outside funding. The researchers and the editorialists had no financial conflicts to disclose.

Watson, DHSc, MS, MPH, of the National Institutes of Health, Bethesda, Md., and Angela Odoms-Young, PhD, of Cornell University, Ithaca, N.Y., wrote in an accompanying editorial.

The findings provide a foundation for studies of obesity-related cancer outcomes that take the community environment into consideration, they added.

The causes of both obesity and cancer are complex, and the study findings suggest that the links between unhealthy food environments and obesity-related cancer may go beyond dietary consumption alone and extend to social and psychological factors, the editorialists noted.

“Whether dealing with the lack of access to healthy foods or an overabundance of unhealthy food, there is a critical need to develop additional research that explores the associations between obesity-related cancer mortality and food inequities,” they concluded.

The study received no outside funding. The researchers and the editorialists had no financial conflicts to disclose.

PHOENIX – Treating superficial and nodular basal cell cancers (BCCs) with an apoptotic process induced by controlled hyperthermia resulted in strong histologic clearance of tumors, an interim report from an ongoing study showed.

“For 2,000 years, it’s been known that heat can kill cancers,” an apoptotic reaction “rather than a destructive reaction coming from excessive heat,” Christopher B. Zachary, MD, said at the annual conference of the American Society for Laser Medicine and Surgery, where the study was presented during an abstract session.

Dr. Zachary, professor and chair emeritus of the department of dermatology at the University of California, Irvine, and colleagues, evaluated a novel, noninvasive technique of controlled hyperthermia and mapping protocol (CHAMP) designed to help clinicians with margin assessment and treatment of superficial and nodular BCCs. For this prospective study, which was first described at the 2022 ASLMS annual conference and is being conducted at three centers, 73 patients with biopsy-proven superficial and nodular BCCs have been scanned with the VivoSight Dx optical coherence tomography (OCT) device to map BCC tumor margins.

The BCCs were treated with the Sciton 1,064-nm Er:YAG laser equipped with a 4-mm beam diameter scan pattern with no overlap and an 8-millisecond pulse duration, randomized to either standard 120-140 J/cm² pulses until tissue graying and contraction was observed, or the CHAMP controlled hyperthermia technique using repeated 25 J/cm² pulses under thermal camera imaging to maintain a consistent temperature of 55º C for 60 seconds. Patients were rescanned by OCT at 3 to 12 months for any signs of residual tumor and if positive, were retreated. Finally, lesions were excised for evidence of histological clearance.

To date, 48 patients have completed the study. Among the 26 patients treated with the CHAMP method, 22 (84.6%) were histologically clear, as were 19 of the 22 (86.4%) in the standard treatment group. Ulceration was uncommon with the CHAMP method, and patients healed with modest erythema, Dr. Zachary said.

Pretreatment OCT mapping of BCCs indicated that tumors extended beyond their 5-mm clinical margins in 11 cases (15%). “This will be of interest to those who treat BCCs by Mohs or standard excision,” he said. Increased vascularity measured by dynamic OCT was noted in most CHAMP patients immediately after irradiation, which suggests that apoptosis was the primary mechanism of tumor response instead of vascular destruction.

“The traditional technique for using the long pulsed 1,064-nm Er:YAG laser to cause damage and destruction of BCC is 120-140 J/cm² at one or two passes until you get to an endpoint of graying and contraction of tissue,” Dr. Zachary said. “That’s opposed to the ‘Low and Slow’ approach [where you use] multiple pulses at 25 J/cm² until you achieve an optimal time and temperature. If you treat above 60º C, you tend to get epidermal blistering, prolonged healing, and interestingly, absence of pain. I think that’s because you kill off the nerve fibers. With the low fluence multiple scan technique, you’re going for an even flat-top heating.”

Currently, he and his colleagues consider 55 degrees at 60 seconds as “the optimal parameters,” he said, but “it could be 45 degrees at 90 seconds or two minutes. We don’t know yet.”

In an interview at the meeting, one of the abstract session moderators, Mathew M. Avram, MD, JD, director of laser, cosmetics, and dermatologic surgery at Massachusetts General Hospital, Boston, said that he was encouraged by the study results as investigations into effective, noninvasive treatment of BCC continue to move forward. “Details matter such as the temperature [of energy delivery] and noninvasive imaging to delineate the appropriate margins,” said Dr. Avram, who has conducted research on the 1,064-nm long-pulsed Nd:YAG laser as an alternative treatment for nonfacial BCCs in patients who are poor surgical candidates.

“Hopefully, at some point,” he said, such approaches will “become the standard of care for many BCCs that we are now treating surgically. I don’t think this will happen in the next 3 years, but I think in the long term, it will emerge as the treatment of choice.”

The study is being funded by Michelson Diagnostics. Sciton provided the long-pulsed 1,064-nm lasers devices being used in the trial. Dr. Zachary reported having no relevant disclosures. Dr. Avram disclosed that he has received consulting fees from Sciton.

Among women with early-stage, high-risk breast cancer, strong adherence to prevention recommendations was linked with a significantly reduced risk of breast cancer recurrence and mortality in a new study.

Following such recommendations surrounding smoking, physical activity (PA), eating fruits and vegetables and reducing or eliminating sugar-sweetened beverages seemed to be the most beneficial, wrote the authors of the paper published online in JAMA Network Open.

Rikki A. Cannioto, PhD, EdD, with the department of cancer prevention & control, Roswell Park Comprehensive Cancer Center in Buffalo, N.Y., led the prospective cohort study of 1,340 patients.

The American Institute for Cancer Research and American Cancer Society regularly recommend and publish lifestyle modifications for cancer prevention. To conduct this study Dr. Cannioto and colleagues developed an aggregate lifestyle scoring index to investigate whether those recommendations have an effect on high-risk breast cancer survival.

Highest adherence vs. lowest cut death risk by more than half

The researchers found patients with highest vs. lowest lifestyle index scores saw a 37% reduction in cancer recurrence (hazard ratio, 0.63; 95% confidence interval, 0.48-0.82) and a 58% reduction in mortality (HR, 0.42; 95% CI, 0.30-0.59).

“As a person who has based her career on the belief that our modifiable lifestyle behaviors are associated with cancer survival, I was actually surprised about how strong these associations were, especially for breast cancer recurrence,” Dr. Cannioto said in an interview,

The author also expressed surprise about the associations that were seen “in patients diagnosed with triple-negative breast cancer and HER2-positive breast cancer, which are the two subtypes traditionally more aggressive and more difficult to treat.”

Most patients in the study were diagnosed with hormone receptor–positive breast cancer (873 [65.3%]); completed some education beyond high school (954 [71.2%]); were postmenopausal (696 [52.5%]); and self-identified as non-Hispanic White (1,118 [83.7%]).

Patients were drawn from the Diet, Exercise, Lifestyles, and Cancer Prognosis (DELCaP) study, a prospective, observational cohort study ancillary to a multicenter phase 3 trial led by the Southwest Oncology Group (SWOG). The DELCaP study was designed to examine lifestyles before diagnosis, during treatment, and at 1 and 2 years after treatment.

Never smoking, physical activity had strongest links

Never smoking and meeting or exceeding PA guidelines had the strongest and most consistent associations with outcomes; each factor was linked with a 44%-45% reduced risk of mortality and a 35% reduced risk of recurrence.

Strongest adherence to the alcohol and body mass index (BMI) recommendations were not significantly associated with improved outcomes.

Partial and full adherence to red and processed meat recommendations were associated with significant reductions in mortality, but not recurrence.

The authors note that, while medications are the foundation for breast cancer treatment, lifestyle interventions could be a safe and inexpensive additional strategy for delaying and preventing recurrence and death.

“Such developments could be especially impactful for patients diagnosed with more aggressive tumors that do not respond well to current therapies,” they write.

Dr. Cannioto says the guidelines around physical activity advise 150 minutes or more of moderate to vigorous intensity a week. But she noted that this research shows that any physical activity can lead to longer survival.

“The greatest benefits from physical activity occur from moving from a sedentary lifestyle to beginning to be active,” she said.

Dr. Cannioto acknowledged the homogeneity of the study population as a limitation and recommended the associations next be tested in a more racially and ethnically diverse population of breast cancer patients.

This work was supported by the National Cancer Institute, the Breast Cancer Research Foundation, and Amgen.

Timing of a switch to treatment from gefitinib to osimertinib based on molecular progression led to an earlier switch than timing based on conventional measures in a new study of 100 adults with epidermal growth factor (EGFR)–mutant non–small cell lung cancer (NSCLC).

Previous studies have suggested that molecular progression of disease in patients with EGFR-mutant NSCLC, as measured by sequential plasma EGFR T790M, may precede radiological progression, as measured by Response Evaluation Criteria in Solid Tumors (RECIST).

However, the impact of these measures on timing of treatment changes and patient outcomes has not been examined, wrote Jordi Remon, MD, of Paris (France)–Saclay University and colleagues, in Annals of Oncology.

The European Organization for Research Treatment and Cancer Lung Cancer Group designed a phase 2 clinical trial known as APPLE to evaluate the use of sequential plasma EGFR T790M and determine the optimal sequencing for gefitinib and osimertinib in patients with EGFR-mutant NSCLC.

The researchers reported results from two randomized arms of the APPLE trial. In arm B, 52 patients received gefitinib until emergence of circulating tumor DNA (ctDNA) EGFR T790M mutation, based on the cobas EGFR test v2 (a real-time PCR test), or progression of disease based on Response Evaluation Criteria in Solid Tumors (RECIST). In arm C, 51 patients received gefitinib until disease progression based on RECIST. Both arms then switched to osimertinib. Patients randomized to a third arm (arm A) received osimertinib upfront until progression of disease based on RECIST, and they were not included in the current study.

The primary endpoint was progression-free survival (PFS) while receiving osimertinib at 18 months in patients who were originally randomized to gefitinib, then switched to osimertinib at the emergence of circulating tumor DNA. Secondary endpoints included PFS, overall response rate, overall survival, and brain PFS.

Patients entered the study between November 2017 and February 2020. A total of 75% and 65% of those in arms B and C, respectively, were female, approximately 65% had the mutation EGFR Del19, and approximately one-third had baseline brain metastases. In arm B, 17% of patients switched to osimertinib based on the emergence of ctDNA T790M mutation before progressive disease based on RECIST. The median time to molecular disease progression was 266 days.

More patients in arm B met the primary endpoint of PFS while receiving osimertinib at 18 months (67.2%) than in arm C (53.5%), after a median follow-up of 30 months.

As for secondary endpoints, the median PFS in the two arms was 22.0 months and 20.2 months, respectively. Median overall survival was 42.8 months in arm C and was not reached in arm B. The median brain PFS was 24.4 months for arm B and 21.4 months for arm C.

The benefits seen in the osimertinib patients may be due in part to the timing of the switch to correspond with molecular or radiological disease progression, the researchers wrote in their discussion.

In the future, more research is needed to determine whether molecular monitoring may impact patients’ outcomes, compared with monitoring based on radiological progression, they said.

The findings were limited by several factors, mainly the rapid evolution in the treatment landscape of EGFR-mutant NSCLC, the researchers noted.

Osimertinib is currently considered the preferred first-line treatment by most physicians, they said. “The APPLE trial is the first prospective study supporting the role of dynamic adaptive strategies based on ctDNA monitoring in patients with EGFR-mutant advanced NSCLC.”

The study was supported by AstraZeneca. Lead author Dr. Remon had no financial conflicts to disclose. Corresponding author Dr. Dziadziuszko disclosed honoraria for consultancy or lectures from AstraZeneca, Roche, Novartis, MSD, Takeda, Pfizer, Amgen, and Bristol-Myers Squibb.

In arm B, 52 patients received gefitinib until emergence of circulating tumor DNA (ctDNA) EGFR T790M mutation, based on the cobas EGFR test v2 (a real-time PCR test), or progression of disease based on Response Evaluation Criteria in Solid Tumors (RECIST). In arm C, 51 patients received gefitinib until disease progression based on RECIST. Both arms then switched to osimertinib. Patients randomized to a third arm (arm A) received osimertinib upfront until progression of disease based on RECIST, and they were not included in the current study.

The primary endpoint was progression-free survival (PFS) while receiving osimertinib at 18 months in patients who were originally randomized to gefitinib, then switched to osimertinib at the emergence of circulating tumor DNA. Secondary endpoints included PFS, overall response rate, overall survival, and brain PFS.

Patients entered the study between November 2017 and February 2020. A total of 75% and 65% of those in arms B and C, respectively, were female, approximately 65% had the mutation EGFR Del19, and approximately one-third had baseline brain metastases. In arm B, 17% of patients switched to osimertinib based on the emergence of ctDNA T790M mutation before progressive disease based on RECIST. The median time to molecular disease progression was 266 days.

More patients in arm B met the primary endpoint of PFS while receiving osimertinib at 18 months (67.2%) than in arm C (53.5%), after a median follow-up of 30 months.

As for secondary endpoints, the median PFS in the two arms was 22.0 months and 20.2 months, respectively. Median overall survival was 42.8 months in arm C and was not reached in arm B. The median brain PFS was 24.4 months for arm B and 21.4 months for arm C.

The benefits seen in the osimertinib patients may be due in part to the timing of the switch to correspond with molecular or radiological disease progression, the researchers wrote in their discussion.

In the future, more research is needed to determine whether molecular monitoring may impact patients’ outcomes, compared with monitoring based on radiological progression, they said.

The findings were limited by several factors, mainly the rapid evolution in the treatment landscape of EGFR-mutant NSCLC, the researchers noted.

Osimertinib is currently considered the preferred first-line treatment by most physicians, they said. “The APPLE trial is the first prospective study supporting the role of dynamic adaptive strategies based on ctDNA monitoring in patients with EGFR-mutant advanced NSCLC.”

The study was supported by AstraZeneca. Lead author Dr. Remon had no financial conflicts to disclose. Corresponding author Dr. Dziadziuszko disclosed honoraria for consultancy or lectures from AstraZeneca, Roche, Novartis, MSD, Takeda, Pfizer, Amgen, and Bristol-Myers Squibb.

The immunotherapy blinatumomab improves short-term outcomes when added to standard chemotherapy for infants with KMT2A-rearranged acute lymphoblastic leukemia (ALL), according to a report in the New England Journal of Medicine.

Two-year disease-free and overall survival measures, as well as the percentage of children who had complete minimal residual disease (MRD) responses, were substantially higher among the 30 infants in the study than in historical controls treated with the same chemotherapy backbone in an earlier trial, Interfant-06.

“These outcome data are very promising, given the poor survival and lack of improvements in outcomes among infants with KMT2A-rearranged ALL in recent decades,” said the investigators, led by Inge M. van der Sluis, MD, PhD, a hematologist-oncologist at Princess Maxima Center for Pediatric Oncology in Utrecht, the Netherlands.

“The low incidence of relapse after treatment with blinatumomab is remarkable, given that in historical controls relapses occur frequently and early during therapy,” the investigators stated. Although the “follow-up time was relatively short” in the study, “it included the period historically defined” as being at high risk of relapse, they said.

The team suggested that future research should assess whether infants benefit from multiple courses of blinatumomab, rather than the one course used in the study, and whether blinatumomab plus chemotherapy can replace stem cell transplants for high-risk infants.
 

Pediatric community responds

There was excitement on Twitter about the results; a number of pediatric blood cancer specialists were impressed and posted the study on that platform. Comments included, “Wow! After years of stagnation, a huge step forward for infant leukemia” and “great news for infant lymphoblastic leukemia.”

Akshay Sharma, MBBS, a pediatric bone marrow transplant and cellular therapy specialist at St. Jude Children’s Research Hospital, Memphis, also posted. He said in an interview that the findings are “very exciting.”

The “outcomes of children diagnosed with leukemia in their infancy, particularly if they have a KMT2A rearrangement, have been dismal. This is terrific progress and a testament to the role that immunotherapy and novel agents will be playing in treatment of several malignant diseases in the decade to come,” he said.

Another poster, Pratik “Tik” Patel, MD, a pediatric hematology/oncology fellow at Emory University in Atlanta, told this news organization that the study “is welcome news to pediatric oncologists” and highlights “the success in incorporating newer immune-based therapeutics upfront in treatment rather than in relapsed/refractory settings.”

The National Cancer Institute–funded Children’s Oncology Group is thinking the same way. The group is launching a large, randomized trial to test if adding blinatumomab to chemotherapy upfront for B-cell acute lymphoblastic leukemia and lymphoblastic lymphoma improves outcomes in children and young adults aged 1-31 years. Results are due after 2029.
 

Study details

Blinatumomab is an expensive “T-cell engager” that helps cytotoxic CD3+T cells link to and destroy leukemic CD19+ B cells. Past studies have shown that it’s safe and works in older children and adults with B-lineage ALL after intensive chemotherapy, but until now the approach hadn’t been tested in infants, the investigators said.

The 30 subjects in the study were under a year old and newly diagnosed with KMT2A-rearranged ALL. They were treated with the Interfant-06 chemotherapy regimen – cytosine arabinoside and other agents – plus one postinduction course of blinatumomab at 15 micrograms/m² per day as a 4-week continuous infusion. Eight of nine high-risk patients had allogeneic hematopoietic stem cell transplants.

Overall survival was 93.3% over a median follow up of 26.3 months, substantially higher than the 65.8% in the Interfant-06 trial. Two-year disease-free survival was 81.6% versus 49.4% in Interfant-06.

Sixteen patients (53%) were MRD negative after blinatumomab infusion and 12 (40%) had low levels of MRD. All of the children who continued chemotherapy went on to become MRD negative.

There were no permanent blinatumomab discontinuations and no treatment related deaths. Serious toxic effects were consistent with those in older patients and included four fevers, four infections, and one case each of hypertension and vomiting.

There were no cases of severe cytokine release syndrome (CRS) because of the low tumor burden of the subjects. Likewise, there were no obvious neurologic adverse events – like CRS, a particular concern with blinatumomab – but “we cannot rule out underreporting of mild neurologic symptoms that may have been unrecognized in infants,” the investigators said.

Patients who relapsed in the study had CNS involvement at relapse. “This underscores the need for adequate intrathecal chemotherapy during the blinatumomab infusion, because the efficacy of blinatumomab for the treatment of CNS leukemia may be limited,” they said.

The work was supported by Amgen, the maker of blinatumomab, as well as the Princess Maxima Center Foundation, the Danish Childhood Cancer Foundation, and others. Dr. Sluis is a consultant and researcher for Amgen. Five other authors were also consultants/advisers/researchers for the company. Dr. Sharma and Dr. Patel didn’t have any relevant disclosures.

The American Society of Clinical Oncology has released updated guidelines for treating anxiety and depression in adult cancer survivors.

Since the last guidelines, published in 2014, screening and assessment for depression and anxiety have improved, and a large new evidence base has emerged. To ensure the most up-to-date recommendations, a group of experts spanning psychology, psychiatry, medical and surgical oncology, internal medicine, and nursing convened to review the current literature on managing depression and anxiety. The review included 61 studies – 16 meta-analyses, 44 randomized controlled trials, and one systematic review – published between 2013 and 2021.

“The purpose of this guideline update is to gather and examine the evidence published since the 2014 guideline ... [with a] focus on management and treatment only.” The overall goal is to provide “the most effective and least resource-intensive intervention based on symptom severity” for patients with cancer, the experts write.

The new clinical practice guideline addresses the following question: What are the recommended treatment approaches in the management of anxiety and/or depression in survivors of adult cancer?

After an extensive literature search and analysis, the study was published online in the Journal of Clinical Oncology.

The expert panel’s recommendations fell into three broad categories – general management principles, treatment and care options for depressive symptoms, and treatment and care options for anxiety symptoms – with the guidelines for managing depression and anxiety largely mirroring each other.

The authors caution, however, that the guidelines “were developed in the context of mental health care being available and may not be applicable within other resource settings.”
 

General management principals

All patients with cancer, along with their caregivers, family members, or trusted confidants, should be offered information and resources on depression and anxiety. The panel gave this a “strong” recommendation but provided the caveat that the “information should be culturally informed and linguistically appropriate and can include a conversation between clinician and patient.”

Clinicians should select the most effective and least intensive intervention based on symptom severity when selecting treatment – what the panelists referred to as a stepped-care model. History of psychiatric diagnoses or substance use as well as prior responses to mental health treatment are some of the factors that may inform treatment choice.

For patients experiencing both depression and anxiety symptoms, treatment of depressive symptoms should be prioritized.

When referring a patient for further evaluation or care, clinicians “should make every effort to reduce barriers and facilitate patient follow-through,” the authors write. And health care professionals should regularly assess the treatment responses for patients receiving psychological or pharmacological interventions.

Overall, the treatments should be “supervised by a psychiatrist, and primary care or oncology providers work collaboratively with a nurse care manager to provide psychological interventions and monitor treatment compliance and outcomes,” the panelists write. “This type of collaborative care is found to be superior to usual care and is more cost-effective than face-to-face and pharmacologic treatment for depression.”
 

Treatment and care options for depressive and anxiety symptoms

For patients with moderate to severe depression symptoms, the panelists again stressed that clinicians should provide “culturally informed and linguistically appropriate information.” This information may include the frequency and symptoms of depression as well as signs these symptoms may be getting worse, with contact information for the medical team provided.

Among patients with moderate symptoms, clinicians can offer patients a range of individual or group therapy options, including cognitive-behavioral therapy (CBT), behavioral activation, mindfulness-based stress reduction, or structured physical activity and exercise. For patients with severe symptoms of depression, clinicians should offer individual therapy with one of these four treatment options: CBT, behavioral activation, mindfulness-based stress reduction, or interpersonal therapy.

The panelists offered almost identical recommendations for patients with anxiety, except mindfulness-based stress reduction was an option for patients with severe symptoms.

Clinicians can also provide pharmacologic options to treat depression or anxiety in certain patients, though the panelists provided the caveat that evidence for pharmacologic management is weak.

“These guidelines make no recommendations about any specific pharmacologic regimen being better than another,” the experts wrote. And “patients should be warned of potential harm or adverse effects.”

Overall, the panelists noted that, as highlighted in the 2014 ASCO guideline, the updated version continues to stress the importance of providing education on coping with stress, anxiety, and depression.

And “for individuals with elevated symptoms, validation and normalizing patients’ experiences is crucial,” the panelists write.

Although the timing of screening is not the focus of this updated review, the experts recognized that “how and when patients with cancer and survivors are screened are important determinants of timely management of anxiety and depression.”

And unlike the prior guideline, “pharmacotherapy is not recommended as a first-line treatment, neither alone nor in combination,” the authors say.

Overall, the panelists emphasize how widespread the mental health care crisis is and that problems accessing mental health care remain. “The choice of intervention to offer patients facing such obstacles should be based on shared decision-making, taking into account availability, accessibility, patient preference, likelihood of adverse events, adherence, and cost,” the experts conclude.

Adults with cancer experienced significant reductions in pain after taking medicinal cannabis, in a study.

Physician-prescribed cannabis, particularly cannabinoids, has been shown to ease cancer-related pain in adult cancer patients, who often find inadequate pain relief from medications including opioids, Saro Aprikian, MSc, a medical student at the Royal College of Surgeons, Dublin, and colleagues, wrote in their paper.

However, real-world data on the safety and effectiveness of cannabis in the cancer population and the impact on use of other medications are lacking, the researchers said.

In the study, published in BMJ Supportive & Palliative Care, the researchers reviewed data from 358 adults with cancer who were part of a multicenter cannabis registry in Canada between May 2015 and October 2018.

The average age of the patients was 57.6 years, and 48% were men. The top three cancer diagnoses in the study population were genitorurinary, breast, and colorectal.

Pain was the most common reason for obtaining a medical cannabis prescription, cited by 72.4% of patients.

Data were collected at follow-up visits conducted every 3 months over 1 year. Pain was assessed via the Brief Pain Inventory (BPI) and revised Edmonton Symptom Assessment System (ESAS-r) questionnaires and compared to baseline values. Patients rated their pain intensity on a sliding scale of 0 (none) to 10 (worst possible). Pain relief was rated on a scale of 0% (none) to 100% (complete).

Compared to baseline scores, patients showed significant decreases at 3, 6 and 9 months for BPI worst pain (5.5 at baseline, 3.6 for 3, 6, and 9 months) average pain (4.1 at baseline, 2.4, 2.3, and 2.7 for 3, 6, and 9 months, respectively), overall pain severity (2.7 at baseline, 2.3, 2.3, and 2.4 at 3, 6, and 9 months, respectively), and pain interference with daily life (4.3 at baseline, 2.4, 2.2, and 2.4 at 3, 6, and 9 months, respectively; P less than .01 for all four pain measures).

“Pain severity as reported in the ESAS-r decreased significantly at 3-month, 6-month and 9-month follow-ups,” the researchers noted.

In addition, total medication burden based on the medication quantification scale (MQS) and morphine equivalent daily dose (MEDD) were recorded at 3, 6, 9, and 12 months. MQS scores decreased compared to baseline at 3, 6, 9, and 12 months in 10%, 23.5%, 26.2%, and 31.6% of patients, respectively. Also compared with baseline, 11.1%, 31.3%, and 14.3% of patients reported decreases in MEDD scores at 3, 6, and 9 months, respectively.

Overall, products with equal amounts of active ingredients tetrahydrocannabinol (THC) and cannabidiol (CBD) were more effective than were those with a predominance of either THC or CBD, the researchers wrote.

Medical cannabis was well-tolerated; a total of 15 moderate to severe side effects were reported by 11 patients, 13 of which were minor. The most common side effects were sleepiness and fatigue, and five patients discontinued their medical cannabis because of side effects. The two serious side effects reported during the study period – pneumonia and a cardiovascular event – were deemed unlikely related to the patients’ medicinal cannabis use.

The findings were limited by several factors, including the observational design, which prevented conclusions about causality, the researchers noted. Other limitations included the loss of many patients to follow-up and incomplete data on other prescription medications in many cases.

The results support the use of medical cannabis by cancer patients as an adjunct pain relief strategy and a way to potentially reduce the use of other medications such as opioids, the authors concluded.

The study was supported by the Canadian Consortium for the Investigation of Cannabinoids, Collège des Médecins du Québec, and the Canopy Growth Corporation. The researchers had no financial conflicts to disclose.

Adults with cancer experienced significant reductions in pain after taking medicinal cannabis, in a study.

Physician-prescribed cannabis, particularly cannabinoids, has been shown to ease cancer-related pain in adult cancer patients, who often find inadequate pain relief from medications including opioids, Saro Aprikian, MSc, a medical student at the Royal College of Surgeons, Dublin, and colleagues, wrote in their paper.

However, real-world data on the safety and effectiveness of cannabis in the cancer population and the impact on use of other medications are lacking, the researchers said.

In the study, published in BMJ Supportive & Palliative Care, the researchers reviewed data from 358 adults with cancer who were part of a multicenter cannabis registry in Canada between May 2015 and October 2018.

The average age of the patients was 57.6 years, and 48% were men. The top three cancer diagnoses in the study population were genitorurinary, breast, and colorectal.

Pain was the most common reason for obtaining a medical cannabis prescription, cited by 72.4% of patients.

Data were collected at follow-up visits conducted every 3 months over 1 year. Pain was assessed via the Brief Pain Inventory (BPI) and revised Edmonton Symptom Assessment System (ESAS-r) questionnaires and compared to baseline values. Patients rated their pain intensity on a sliding scale of 0 (none) to 10 (worst possible). Pain relief was rated on a scale of 0% (none) to 100% (complete).

NEW YORK – In a blood cancer conference session – “Will autologous stem cell transplant (ASCT) continue to be the standard of care (SoC) in frontline therapy for multiple myeloma (MM)?” – two experts weighed in on the merits of their approaches to treating MM at the Great Debates and Updates Hematologic Malignancies conference.

Hematologist-oncologists whose top priority is ensuring that patients have the best chance of progression-free survival (PFS) will continue to choose ASCT as a best practice, argued Amrita Krishnan, MD, hematologist at the Judy and Bernard Briskin Center for Multiple Myeloma Research, City of Hope Comprehensive Cancer Center, Duarte, Calif.

A differing perspective was presented by C. Ola Landgren, MD, PhD, hematologist at the Sylvester Comprehensive Cancer Center at the University of Miami. Dr. Landgren cited evidence that, for newly diagnosed MM patients treated successfully with modern combination therapies, ASCT is not a mandatory treatment step before starting maintenance therapy. 

Making a case for ASCT as the SoC, Dr. Krishnan noted, “based on the DETERMINATION trial [DT], there is far superior rate of PFS with patients who get ASCT up front, compared patients who got only conventional chemotherapy with lenalidomide, bortezomib, and dexamethasone [RVd]. PFS is the endpoint we look for in our treatment regimens.

“If you don’t use ASCT up front, you may lose the opportunity at later relapse. This is not to say that transplant is the only tool at our disposal. It is just an indispensable one. The GRIFFIN trial [GT] has shown us that robust combinations of drugs [both RVd and dexamethasone +RVd] can improve patient outcomes both before and after ASCT,” Dr. Krishnan concluded.

In his presentation, Dr. Landgren stated that, in the DT, while PFS is prolonged by the addition of ASCT to RVd, adding ASCT did not significantly increase overall survival (OS) rates. He added that treatment-related AEs of grade 3+ occurred in only 78.2% of patients on RVd versus 94.2% of RVd + ASCT patients.

“ASCT should not be the SoC frontline treatment in MM because it does not prolong OS. The IFM trial and the DT both show that there is no difference in OS between drug combination therapy followed by transplant and maintenance versus combination therapy alone, followed by transplant and maintenance. Furthermore, patients who get ASCT have higher risk of developing secondary malignancies, worse quality of life, and higher long-term morbidity with other conditions,” Dr. Landgren said.

He cited the MAIA trial administered daratumumab and lenalidomide plus dexamethasone (DRd) to patients who were too old or too frail to qualify for ASCT. Over half of patients in the DRd arm of MAIA had an estimated progression-free survival rate at 60 months.

“Furthermore, GT and the MANHATTAN clinical trials showed that we can safely add CD38-targeted monoclonal antibodies to standard combination therapies [lenalidomide, bortezomib, and dexamethasone (KRd)], resulting in higher rates of minimal-residual-disease (MRD) negativity. That means modern four-drug combination therapies [DR-RVd and DR-KRd] will allow more [and more newly diagnosed] MM patients to achieve MRD negativity in the absence of ASCT,” Dr. Landgren concluded.

Asked to comment on the two viewpoints, Joshua Richter, MD, director of myeloma treatment at the Blavatnik Family Center at Chelsea Mount Sinai, New York, said: “With some patients, we can get similar outcomes, whether or not we do a transplant. Doctors need to be better at choosing who really needs ASCT. Older people with standard-risk disease or people who achieve MRD-negative status after pharmacological treatment might not need to receive a transplant as much as those who have bulk disease or high-risk cytogenetics.

“Although ASCT might not be the best frontline option for everyone, collecting cells from most patients and storing them has many advantages. It allows us to do have the option of ASCT in later lines of therapy. In some patients with low blood counts, we can use stored cells to reboot their marrow and make them eligible for trials of promising new drugs,” Dr. Richter said.

Dr. Krishnan disclosed relationships with Takeda, Amgen, GlaxoSmithKline, Bristol-Myers Squibb, Sanofi, Pfizer, Adaptive, Regeneron, Janssen, AstraZeneca, Artiva, and Sutro. Dr. Landgren reported ties with Amgen, BMS, Celgene, Janssen, Takedam Glenmark, Juno, Pfizer, Merck, and others. Dr. Richter disclosed relationships with Janssen, BMS, and Takeda.

The U.S. government plans to no longer require federal workers or international air travelers to be vaccinated for COVID-19, the Biden administration has announced. 

The move means vaccines will no longer be required for workers who are federal employees, federal contractors, Head Start early education employees, workers at Medicare-certified health care facilities, and those who work at U.S. borders. International air travelers will no longer be required to prove their vaccination status. The requirement will be lifted at the end of the day on May 11, which is also when the federal public health emergency declaration ends.

“While vaccination remains one of the most important tools in advancing the health and safety of employees and promoting the efficiency of workplaces, we are now in a different phase of our response when these measures are no longer necessary,” an announcement from the White House stated.

White House officials credited vaccine requirements with saving millions of lives, noting that the rules ensured “the safety of workers in critical workforces including those in the healthcare and education sectors, protecting themselves and the populations they serve, and strengthening their ability to provide services without disruptions to operations.”

More than 100 million people were subject to the vaccine requirement, The Associated Press reported. All but 2% of those covered by the mandate had received at least one dose or had a pending or approved exception on file by January 2022, the Biden administration said, noting that COVID deaths have dropped 95% since January 2021 and hospitalizations are down nearly 91%.

In January, vaccine requirements were lifted for U.S. military members.

On the government-run website Safer Federal Workforce, which helped affected organizations put federal COVID rules into place, agencies were told to “take no action to implement or enforce the COVID-19 vaccination requirement” at this time.
