WASHINGTON – Noninvasive diagnostic devices may increasingly play a part in which lesions you choose to biopsy, Darrell S. Rigel, MD, said at the annual meeting of the American Academy of Dermatology.

“If you incorporate the data from these devices into the biopsy decision, you can improve biopsy sensitivity and accuracy of selection. I think there’s no question with these technologies that’s a true statement,” said Dr. Rigel, of New York University Langone Health.

When considering diagnostic devices, evaluate whether they produce results that outperform dermatologists, are low cost, user-friendly, time-efficient and have a high sensitivity and specificity, Dr. Rigel advised. But since no device has a perfect sensitivity and specificity, they cannot be followed blindly. The data from these devices should be used to inform, but not replace, clinical decisions made by dermatologists.

“They’re basically additional information to integrate into the biopsy decision,” he said. “At the end of the day, if you see something with a low score but it really looks funky, the reality is you have to really consider it for biopsy.”

Dr. Rigel discussed five device types that were used to analyze a number of preselected, noninvasive melanoma lesions. The devices required little training to use and a dermatologist would be required to correctly identify the lesions in a deeper analysis.

• Multispectral digital skin lesion analysis (MDSLA) uses 10 spectral wavelengths to measure the light reflected from the tissue, generating a score from a proprietary algorithm that predicts the risk of melanoma. Use of MDSLA improved the biopsy sensitivity for melanoma from 65% to 93% among 179 dermatologists who reviewed images of 24 lesions, 5 of which were melanoma (Arch Dermatol. 2012;148(4):541-3).
• Spectrophotometric intracutaneous analysis scope uses a similar analytic method as the MDSLA device but is difficult to find in the United States; however, one recent study cited a sensitivity of 81.4% and a specificity of 86.4%, indicating it has value for diagnosing melanoma.
• Raman spectroscopy uses monochromatic laser light to analyze the vibratory patterns of cells and examines the shifts in the light to identify a “molecular fingerprint” of potentially cancerous cells, has a high sensitivity and a “relatively reasonable specificity,” Dr. Rigel said.
• Elastic scattering spectroscopy, a newer technology that uses a smartphone-sized device to measure the difference in light scattered from different cellular structures, holds promise to reduce the number of negative biopsies when differentiating between malignant and benign skin conditions. It is currently pending approval with the Food and Drug Administration.
• Electrical impedance spectroscopy (EIS), which uses an electrical alternating current to detect the electrical resistance of potentially cancerous tissue, generates a score with a high negative predictive value and a higher positive predictive value as the score increases. In a study of melanoma diagnoses made by dermatology trainees, use of EIS decreased the number of missed melanomas by 23.4% and resulted in fewer benign biopsies. (J Amer Acad Dermatol. 2019;80:285-7).

All these technologies have been proven effective, but have encountered various economic roadblocks, including delays in regulatory approval, which are partly responsible for why some are no longer on the market, Dr. Rigel said. “If you have to wait 5 years or 7 years to get approval of these devices, by the time they’re approved, the technology is already passed by.”

There are also issues with reimbursements, Dr. Rigel noted, which can further reduce the clinical implementation of these technologies.

Dr. Rigel reported relationships with Derm Tech International, Scibase (maker of EIS) and a number of dermatologic drug companies.

Diet plays an important role in patient response to anti-programmed death-1 (PD-1) cancer immunotherapy, preliminary findings from a gut microbiome study involving 146 melanoma patients suggest.

Specifically, a high-fiber diet was associated with a more diverse gut microbiome and with improved response to anti-PD-1 therapy, whereas a diet high in sugar and processed meat was associated with fewer of the gut bacteria known to be associated with improved response, Christine Spencer, PhD, reported during a press conference highlighting data to be presented at the upcoming American Association for Cancer Research (AACR) annual meeting in Atlanta.

“We found that patients who reported eating high-fiber diets were about five times as likely to respond to anti-PD-1 checkpoint blockade immunotherapy (odds ratio vs. low-fiber diet, 5.3),” said Dr. Spencer, a research scientist at the Parker Institute for Cancer Immunotherapy.

Notably, more than 40% of patients reported taking probiotics, and those, surprisingly, were also associated with reduced gut microbiome diversity, she said.

For this study, Dr. Spencer and her colleagues at the University of Texas MD Anderson Cancer Center, Houston, analyzed prospectively collected fecal samples from 146 melanoma patients, and collected baseline diet information via the National Cancer Institute dietary screener questionnaire, as well as information about probiotic and antibiotic use, in a subset of 113 who were initiating therapy at MD Anderson. Those patients were then followed to assess therapy response.

“Our early data suggest that different foods and supplements may impact response to cancer immunotherapy in patients, and we think this is likely mediated by the gut microbiome,” she said.

Since only 20%-30% of cancer patients respond to immunotherapy, the findings hint at potential approaches for improving gut microbiome diversity, and thus response to anti-PD-1 cancer immunotherapy.

“Eat your high-fiber foods: fruits, vegetables, and whole grains – lots of different kinds and lots of them,” she said. “High-fiber diets have been linked to health benefits in several other contexts, and this study, although preliminary, shows fiber is linked to more favorable gut microbiome in patients, and better response to cancer immunotherapy.”

Conversations about the use of probiotic supplements also are important, she said.

“A lot of people have the perception that probiotics will provide health benefits, but that might not be the case in cancer patients. We’re not saying all of them are bad, but the message is that these factors have never before been studied in patients on immunotherapy, and our data suggest for the first time that they could matter,” she said, noting that future directions include validation of the findings in larger cohorts.

The Food and Drug Administration has approved pembrolizumab (Keytruda) for the adjuvant treatment of patients with melanoma with lymph node involvement following resection.

FDA approval is based on results from the randomized, double-blind, placebo-controlled EORTC1325/KEYNOTE‑054 trial, in which 1,019 patients with completely resected stage III melanoma received either a placebo or 200 mg of pembrolizumab every 3 weeks for up to 1 year until disease recurrence or unacceptable toxicity.

Recurrence-free survival was significantly better in the pembrolizumab group than in the placebo group (hazard ratio, 0.57; 95% confidence interval, 0.46-0.70; P less than .001). The median recurrence-free survival time was 20.4 months in the placebo group and was not reached in the pembrolizumab group, the FDA said in a press release.

About three-quarters of patients received pembrolizumab for at least 6 months, while 14% of patients had to stop pembrolizumab treatment because of adverse events. The most common adverse events in pembrolizumab-treated patients included diarrhea, pruritus, nausea, arthralgia, hypothyroidism, cough, rash, asthenia, influenzalike illness, weight loss, and hyperthyroidism.

“The recommended pembrolizumab dose and schedule for the adjuvant treatment of melanoma is 200 mg administered as an IV infusion over 30 minutes every 3 weeks until disease recurrence or unacceptable toxicity, for a maximum of 1 year,” the FDA said in the press release.

Immune checkpoint inhibitors are safe and effective in HIV-infected patients with advanced cancers, according to authors of a recently published systematic review.

The treatment was well tolerated and associated with a 9% rate of grade 3 or higher immune-related adverse events, according to results of the review of 73 patient cases.

There were no adverse impacts on HIV load or CD4 cell count detected in the patients, according to researchers Michael R. Cook, MD, and Chul Kim, MD, MPH, of Georgetown University, Washington.

Antitumor activity of the checkpoint inhibitors in lung cancer patients was comparable to what has been seen in previous randomized clinical trials that excluded HIV-infected individuals, Dr. Cook and Dr. Kim reported in JAMA Oncology.

“Based on the results of the present systematic review, and in the absence of definitive prospective data suggesting an unfavorable risk-to-benefit ratio, immune checkpoint inhibitor therapy may be considered as a viable treatment option for HIV-infected patients with advanced cancer,” they said.

There are preclinical data suggesting that immune checkpoint modulation could improve function of HIV-specific T cells, the investigators added.

“Prospective trials of immune checkpoint inhibitors are necessary to elucidate the antiviral efficacy of immune checkpoint inhibitor therapy in patients with HIV infection and cancer,” they said.

Several such trials are underway to evaluate the role of the pembrolizumab, nivolumab, nivolumab plus ipilimumab, and durvalumab in HIV-infected patients with advanced-stage cancers, according to the review authors.

In the present systematic review, Dr. Cook and Dr. Kim conducted a literature search and reviewed presentations from major annual medical conferences.

Of the 73 HIV-infected patients they identified, most had non–small cell lung cancer (34.2%), melanoma (21.9%), or Kaposi sarcoma (12.3%), while the rest had anal cancer, head and neck cancer, or other malignancies. Most patients had received either nivolumab (39.7%) or pembrolizumab (35.6%).

There were “no concerning findings” among these patients with regard to immune-mediated toxicities or changes in HIV-related parameters.

Six of 70 patients had immune-related adverse events of grade 3 or greater.

Thirty-four patients had documented HIV loads before and after receiving an immune checkpoint inhibitor. Of those, 28 had undetectable HIV loads at baseline, and all but 2 (7%) maintained undetectable loads in the posttreatment evaluation.

Of the remaining six with detectable HIV loads before treatment, five had a decrease in viral load, to the point that four had undetectable HIV viral load in the posttreatment evaluation, the investigators reported.

The overall response rate was 30% for the lung cancer patients, 27% for melanoma, and 63% for Kaposi sarcoma.

In the non–small cell lung cancer subset, response rates were 26% for those who had received previous systemic treatment, and 50% for those who had not, which was similar to findings from major checkpoint inhibitor trials that excluded HIV-infected individuals, the investigators said.

The American Society of Clinical Oncology Conquer Cancer Foundation and Georgetown University supported the study. Dr. Kim reported disclosures related to CARIS Life Science and AstraZeneca.

WASHINGTON – Unquestionably, immunotherapy is revolutionizing the care of patients with various solid tumors and hematologic malignancies.

Neil Osterweil/MDedge News

But it’s equally true that there’s no such thing as either a free lunch or a cancer therapy free of side effects, whether it’s increased risk for heart failure associated with anthracycline-based chemotherapy, or inflammatory conditions, arrhythmias, and thromboembolic events associated with immune checkpoint inhibitors, said R. Frank Cornell, MD, of Vanderbilt University Medical Center in Nashville, Tenn.

“Early awareness and intervention is critical for improved outcomes, and a multidisciplinary approach between oncology, cardiology, the clinic nurse, and other health care providers is critical in managing these patients with these complicated therapies,” he said at the American College of Cardiology’s Advancing the Cardiovascular Care of the Oncology Patient meeting.
 

Checkpoint inhibitors and the heart

Toxicities associated with immune checkpoint inhibitors such as the programmed death 1/ligand 1 (PD-1/PD-L1) inhibitors nivolumab (Opdivo) and pembrolizumab (Keytruda) and the cytotoxic T-lymphocyte antigen 4 antibody ipilimumab (Yervoy) tend to mimic autoimmune conditions, Dr. Cornell said.

Cardiovascular events associated with these agents, while uncommon, include myocarditis, pericarditis, arrhythmias, impaired ventricular function with heart failure, vasculitis, and venous thromboembolism, he said, citing an American Society of Clinical Oncology (ASCO) clinical practice guideline (J Clin Oncol 2018;36[17]:1714-68).

Dr. Cornell described the case of a 63-year-old woman with disseminated metastatic melanoma who presented to the emergency department 10 days after starting on combination therapy with ipilimumab and nivolumab. She had developed shortness of breath, pleuritic chest pain, and a mild cough for 1 or 2 days.

Her cardiac laboratory markers had been normal at baseline, but were markedly elevated on presentation, and electrocardiograms showed complete heart block and subsequent ventricular tachycardia.

The patient was started on high-dose prednisone, but she died in hospital, and an autopsy showed that the cause of death was infiltration into the myocardium of CD3-positive and CD8-positive T lymphocytes.

“So how do we manage this? This is a good opportunity, I think, for further cardiology and oncology collaboration to develop more robust guidelines for what we can do to best prevent this,” Dr. Cornell said.

Patients started on the ipilimumab/nivolumab combination should be tested weekly for cardiac troponin, creatine kinase (CK) and CK-muscle/brain (CK-MB) weekly for the first 3-4 weeks of therapy. Therapy should be stopped if troponin levels continue to rise, and the patient should be started on high-dose steroids, he said.

The role of other anti-inflammatory agents such as infliximab (Remicade and biosimilars) is unclear and needs further study, he added.

Dr. Cornell cited a 2018 letter to The Lancet by Javid J. Moslehi, MD, and colleagues from Vanderbilt describing an increase in reports of fatal myocarditis among patients treated with checkpoint inhibitors.

“We highlight the high mortality rate with severe immune checkpoint inhibitor–related myocarditis, which is more frequent with combination PD-1 and CTLA-4 blockade, but can also occur with monotherapy. Myocarditis was observed across immune checkpoint inhibitor regimens, although it remains too early to determine whether the incidence differs between use of anti-PD1 and anti-PD-L1 drugs. Furthermore, this condition occurs early on during therapy and across cancer types,” they wrote.

Most of the patients had no preexisting cardiovascular disease, and most were not taking medications for hypertension, cardiovascular disease, or diabetes.
 

CAR-T cells and cardiac disease

The primary cardiac complications associated with CAR-T cell therapy are related to the cytokine release syndrome (CRS), a condition marked by progressive elevation in inflammatory cytokines that in turn leads to marked elevations in C-reactive protein (CRP), interferon gamma, tumor necrosis factor al, and release of pro-inflammatory cytokines including interleukin (IL) 6, IL-10, IL-12, and IL-1 beta.

In rare instances, CRS can lead to disseminated intravascular coagulation (DIC), capillary leak syndrome, and a hemophagocytic lymphohistiocytosis-like (HLH) syndrome, Dr. Cornell said.

Package inserts for the two Food and Drug Administration–approved CAR-T cell products, axicabtagene ciloleucel (Yescarta) and tisagenlecleucel (Kymriah) show that each was associated in clinical trials with a high incidence of CRS.

Among patients treated with axicabtagene ciloleucel, 94% developed CRS, which was grade 3 or greater in severity in 13%. The median time to onset was 2 days, and the median duration was 7 days. Cardiovascular adverse events included grade 3 or greater tachycardia in 2%, arrhythmias in 7%, edema in 1%, dyspnea in 3%, pleural effusion in 2%, hypotension in 15%, hypertension in 6%, and thrombosis in 1%.

Among patients treated with tisagenlecleucel, 79% treated for B-cell acute lymphoblastic leukemia (B-ALL) and 74% treated for diffuse large B cell lymphoma (DLBCL) developed CRS, which was grade 3 or greater in 49% and 23% of patients, respectively. The median time to onset was 3 days, and the median duration of CRS was 8 days.

Cardiovascular adverse events of grade 3 or greater among these patients included tachycardia in 4%, fluid overload in 7%, edema in 1%, dyspnea in 12%, pulmonary edema in 4%, hypotension in 22%, and hypertension in 6%.

Risk factors for CRS include high pre-infusion tumor burden, active infections, and concurrent inflammatory processes, Dr. Cornell said.

Prevention of cardiovascular complications of CAR-T cell therapy requires management of CRS. Patients with grade 2 or greater CRS should receive the anti-IL-6 agent tocilizumab (Actemra) 8 mg/kg intravenously over 1 hour to a maximum dose of 800 mg. Tocilizumab infusions can be repeated every 8 hours as needed if the patient is not responsive to intravenous fluids or increasing supplement oxygen, but should be limited to a maximum of three doses over 24 hours, and a maximum total of four doses.

Patients with grade 3 CRS should also receive intravenous methylprednisolone 1 mg/kg twice daily or the equivalent amount of dexamethasone, with corticosteroids continued until the severity of CRS is grade 1 or less, then tapered over 3 days,

Patients with grade 4 CRS should also receive IV methylprednisolone 1,000 mg per day for 3 days, and if symptoms improve, continue management as per grade 3, Dr. Cornell said.

Dr. Cornell reported having nothing to disclose.

But it’s equally true that there’s no such thing as either a free lunch or a cancer therapy free of side effects, whether it’s increased risk for heart failure associated with anthracycline-based chemotherapy, or inflammatory conditions, arrhythmias, and thromboembolic events associated with immune checkpoint inhibitors, said R. Frank Cornell, MD, of Vanderbilt University Medical Center in Nashville, Tenn.

“Early awareness and intervention is critical for improved outcomes, and a multidisciplinary approach between oncology, cardiology, the clinic nurse, and other health care providers is critical in managing these patients with these complicated therapies,” he said at the American College of Cardiology’s Advancing the Cardiovascular Care of the Oncology Patient meeting.
 

Checkpoint inhibitors and the heart

Toxicities associated with immune checkpoint inhibitors such as the programmed death 1/ligand 1 (PD-1/PD-L1) inhibitors nivolumab (Opdivo) and pembrolizumab (Keytruda) and the cytotoxic T-lymphocyte antigen 4 antibody ipilimumab (Yervoy) tend to mimic autoimmune conditions, Dr. Cornell said.

Cardiovascular events associated with these agents, while uncommon, include myocarditis, pericarditis, arrhythmias, impaired ventricular function with heart failure, vasculitis, and venous thromboembolism, he said, citing an American Society of Clinical Oncology (ASCO) clinical practice guideline (J Clin Oncol 2018;36[17]:1714-68).

Dr. Cornell described the case of a 63-year-old woman with disseminated metastatic melanoma who presented to the emergency department 10 days after starting on combination therapy with ipilimumab and nivolumab. She had developed shortness of breath, pleuritic chest pain, and a mild cough for 1 or 2 days.

Her cardiac laboratory markers had been normal at baseline, but were markedly elevated on presentation, and electrocardiograms showed complete heart block and subsequent ventricular tachycardia.

The patient was started on high-dose prednisone, but she died in hospital, and an autopsy showed that the cause of death was infiltration into the myocardium of CD3-positive and CD8-positive T lymphocytes.

“So how do we manage this? This is a good opportunity, I think, for further cardiology and oncology collaboration to develop more robust guidelines for what we can do to best prevent this,” Dr. Cornell said.

WASHINGTON – The personalized NEO-PV-1 neoantigen vaccine plus poly-ICLC adjuvant in combination with the checkpoint inhibitor nivolumab is well tolerated and shows clinical activity, according to findings from the ongoing phase 1b NT-001study of patients with metastatic melanoma, smoking-associated non–small cell lung cancer (NSCLC), and bladder cancer.

No vaccine-related serious adverse events occurred in 34 patients in a per-protocol set who were treated with the regimen, Siwen Hu-Lieskovan, MD, PhD, reported at the annual meeting of the Society for Immunotherapy of Cancer.

“We found that NEO-PV-01 in combination with nivolumab was very safe; we did not see any grade 3 to grade 4 toxicity associated with the combination,” said Dr. Hu-Lieskovan, a medical oncologist at the University of California, Los Angeles.

Most adverse events that occurred were mild and related to the local injection, she noted.

Although safety was the primary endpoint of the study, Dr. Hu-Lieskovan and her colleagues also looked at immune responses and treatment efficacy, however, with respect to translational data her presentation addressed only the findings in the melanoma and lung cancer patients.

All patients exhibited an immune response to the vaccine, with 56% of the epitopes generating CD4- and/or CD8-positive T cell responses.

“These immune responses were very durable and still could be detected 52 weeks into the treatment,” she said. Additionally, epitope spreading – increased immune response targeting nonvaccine epitopes (which is indirect evidence of vaccine-induced tumor toxicity) – was observed in 8 of 10 patients tested.

The study subjects, including 16 adults with melanoma, 11 with NSCLC, and 7 with bladder cancer, were treated with nivolumab every 2 weeks for 12 weeks prior to vaccination (while their personalized vaccine was being developed). NEO-PV-01 – which included up to 20 unique peptides plus the immunostimulant poly-ICLC – was then administered subcutaneously in five priming doses followed by two booster doses over the next 12 weeks. Of note, very few patients had programmed cell death protein 1 expression of 50% or greater, including only 13.3%, 28.6%, and 0% of the melanoma, NSCLC, and bladder cancer patients, respectively, and tumor mutation burden was consistent with published reports, she said.

As for efficacy, 11 of 16 melanoma patients (68.6%) had either a partial response (8 pre vaccination and an additional 3 post vaccination) or stable disease. One (6.3%) had a postvaccination complete response, Dr. Hu-Lieskovan said.

“[This is] much better than the historical data,” she noted, adding that 12 patients (75%) are still on the study and continuing treatment with response duration of at least 39.7 weeks.

Of the 11 NSCLC patients, 5 (45.5%) had a partial response (3 pre vaccination and 2 post vaccination), and none had a complete response. Seven (63.6%) remained on the study and were continuing treatment, and response duration was at least 30.6 weeks.

An exploratory analysis of tumor responses after vaccination showed that the majority of melanoma patients and half of the lung cancer patients had further tumor shrinkage after vaccination, and some patients were converted to responders. Most – including some with stable or progressive disease – stayed on treatment, she said.

The findings demonstrate that NEO-PV-01 is very well tolerated and associated with post vaccine responses observed after week 24.

“We saw evidence of vaccination-induced immune response specific to the injected vaccine, as well as epitope spreading, and the T cells induced by these neoantigens can traffic into the tumor and they seem to be functional,” she concluded.

Dr. Hu-Lieskovan reported receiving consulting fees and/or research support from Amgen, BMS, Genmab, Merck, and Vaccinex. She is the UCLA site principal investigator for the NT-001 study and has conducted contracted research for Astellas, F Star, Genentech, Nektar Therapeutics, Neon Therapeutics, Pfizer, Plexxikon, and Xencor.

Suicide risk significantly increases within the first year of a cancer diagnosis, with risk varying by type of cancer, according to investigators who conducted a retrospective analysis representing nearly 4.7 million patients.

Risk of suicide in that first year after diagnosis was especially high in pancreatic and lung cancers, while by contrast, breast and prostate cancer did not increase suicide risk, reported the researchers, led by Hesham Hamoda, MD, MPH, of Boston Children’s Hospital/Harvard Medical School, and Ahmad Alfaar, MBBCh, MSc, of Charité–Universitätsmedizin Berlin.

That variation in suicide risk by cancer type suggests that prognosis and 5-year relative survival play a role in increasing suicide rates, according to Dr. Hamoda, Dr. Alfaar, and their coauthors.

“After the diagnosis, it is important that health care providers be vigilant in screening for suicide and ensuring that patients have access to social and emotional support,” they wrote in a report published in Cancer. Their analysis was based on 4,671,989 patients with a diagnosis of cancer in the Surveillance, Epidemiology, and End Results (SEER) database between 2000 and 2014. Out of 1,005,825 of those patients who died within the first year of diagnosis, the cause of death was suicide for 1,585, or 0.16%.

Overall, the risk of suicide increased significantly among cancer patients versus the general population, with an observed-to-expected (O/E) ratio of 2.51 per 10,000 person-years, the investigators found. The risk was highest in the first 6 months, with an O/E mortality of 3.13 versus 1.8 in the latter 6 months.

The highest ratios were seen for pancreatic cancer, with an O/E ratio of 8.01, and lung cancer, with a ratio of 6.05, the researchers found in further analysis.

Significant increases in suicide risk were also seen for colorectal cancer (2.08) and melanoma (1.45), though rates were not significantly different versus the general population for breast (1.23) and prostate (0.99), according to the reported data.

Suicide risk was relatively high for any cancer with distant metastases (5.63), though still significantly higher at 1.65 in persons with localized/regional disease, the data show.

The increased suicide risk persisted more than 1 year after the cancer diagnosis, though not to the degree observed within that first year, they added.

Most patients with suicide as a cause of death were white (90.2%) and male (87%). Nearly 60% were between the ages of 65 and 84 at the time of suicide.

Social support plays an integral role in suicide prevention among cancer patients, the researchers noted.

Previous studies suggest that support programs may decrease suicide risk by making patients better aware of their prognosis, receptive to decreased social stigma, or less likely to have stress related to cost of care, they said.

“Discussing the quality of life after diagnosis, the effectiveness of therapy, and the prognosis of the disease and maintaining a trusting relationship with health care professionals all decrease the likelihood of suicide immediately after a diagnosis of cancer,” they said.

Dr. Hamoda, Dr. Alfaar, and their coauthors reported no conflicts of interest. Funding for the study came in part from the German Academic Exchange Service (Dr. Alfaar).

Their analysis was based on 4,671,989 patients with a diagnosis of cancer in the Surveillance, Epidemiology, and End Results (SEER) database between 2000 and 2014. Out of 1,005,825 of those patients who died within the first year of diagnosis, the cause of death was suicide for 1,585, or 0.16%.

Overall, the risk of suicide increased significantly among cancer patients versus the general population, with an observed-to-expected (O/E) ratio of 2.51 per 10,000 person-years, the investigators found. The risk was highest in the first 6 months, with an O/E mortality of 3.13 versus 1.8 in the latter 6 months.

The highest ratios were seen for pancreatic cancer, with an O/E ratio of 8.01, and lung cancer, with a ratio of 6.05, the researchers found in further analysis.

Significant increases in suicide risk were also seen for colorectal cancer (2.08) and melanoma (1.45), though rates were not significantly different versus the general population for breast (1.23) and prostate (0.99), according to the reported data.

Suicide risk was relatively high for any cancer with distant metastases (5.63), though still significantly higher at 1.65 in persons with localized/regional disease, the data show.

The increased suicide risk persisted more than 1 year after the cancer diagnosis, though not to the degree observed within that first year, they added.

Most patients with suicide as a cause of death were white (90.2%) and male (87%). Nearly 60% were between the ages of 65 and 84 at the time of suicide.

Social support plays an integral role in suicide prevention among cancer patients, the researchers noted.

Previous studies suggest that support programs may decrease suicide risk by making patients better aware of their prognosis, receptive to decreased social stigma, or less likely to have stress related to cost of care, they said.

“Discussing the quality of life after diagnosis, the effectiveness of therapy, and the prognosis of the disease and maintaining a trusting relationship with health care professionals all decrease the likelihood of suicide immediately after a diagnosis of cancer,” they said.

Dr. Hamoda, Dr. Alfaar, and their coauthors reported no conflicts of interest. Funding for the study came in part from the German Academic Exchange Service (Dr. Alfaar).

Suicide risk significantly increases within the first year of a cancer diagnosis, with risk varying by type of cancer, according to investigators who conducted a retrospective analysis representing nearly 4.7 million patients.

Risk of suicide in that first year after diagnosis was especially high in pancreatic and lung cancers, while by contrast, breast and prostate cancer did not increase suicide risk, reported the researchers, led by Hesham Hamoda, MD, MPH, of Boston Children’s Hospital/Harvard Medical School, and Ahmad Alfaar, MBBCh, MSc, of Charité–Universitätsmedizin Berlin.

The Food and Drug Administration has granted accelerated approval for pembrolizumab (Keytruda) for the treatment of pediatric and adult Merkel cell carcinoma, specifically for recurrent locally advanced or metastatic disease.

Because it is an accelerated approval, “continued approval for this indication may be contingent upon verification and description of clinical benefit in the confirmatory trials,” according to the FDA press release announcing the approval.

Pembrolizumab is a programmed death receptor-1 (PD-1)-blocking antibody that was previously approved for treatment of unresectable or metastatic melanoma.

More about the latest approval, as well as full prescribing information, can be found on the FDA’s website.

Severe sleep-disordered breathing was significantly associated with more aggressive skin cancer in a study of 443 adults.

Dlumen/Thinkstock

Sleep-disordered breathing (SDB) has been associated with increased cancer risk and mortality, but no large studies have examined the association in specific cancers, wrote Miguel Angel Martinez-Garcia, MD, of La Fe University and Polytechnic Hospital, Valencia, Spain, and his colleagues.

The researchers conducted a sleep study of 443 adults with melanoma within 6 months of their diagnoses. The findings were published in the journal CHEST®. Overall, patients with more severe sleep apnea were nearly twice as likely to have aggressive type melanoma, compared with those with less severe sleep apnea.

Sleep apnea was defined via the Apnea Hypopnea Index (AHI) and the desaturation indices (DI). Aggressive melanoma was defined as a Breslow index greater than 1 mm, compared with 1 mm or less.

Patients with AHI greater than 15.6 events per hour or in the DI4% tertile (more than 9.3 desaturations per hour) were approximately twice as likely (1.94 and 1.93 times, respectively) to have a more aggressive melanoma as were those with less severe sleep apnea, after adjustment for age, gender, body mass index, and melanoma location.

The average age of the patients was 60 years, 51% were male, and the average time between the melanoma diagnosis and the sleep study was 82 days. Sleep symptoms were not significantly different between the patients with aggressive or less aggressive melanoma. However, in addition to more severe sleep apnea, those with aggressive melanoma were significantly more likely to be older, male, and have a higher BMI than were those with less aggressive disease.

“Among the most salient findings were the dependence of the association between SDB and the markers of melanoma aggressiveness on both age and the actual indicators of tumor aggressiveness,” the researchers noted. The association was significant in patients younger than 55 years only if their Breslow index was greater than 2 mm, the researchers said.

The study findings were limited by the absence of full overnight polysomnography to assess SDB because not all participating centers had access to that option, the researchers noted. However, the results support an independent link between sleep apnea and common measures of aggressive melanoma, especially in younger patients, they said. “Future prospective studies are needed to confirm whether the presence and treatment of SDB and its evolution over time are also associated with poor melanoma outcomes, including death, the pathophysiological mechanisms underlying this association,” they added.

The study was supported in part by Fondo de Investigation Sanitaria, SEPAR, Red Respira, and Sociedad Valenciana de Neumología. The researchers had no financial conflicts to disclose

A review of registry data from a major cancer center revealed a strong, bidirectional association between renal cell carcinoma (RCC) and melanoma.

A greater than twofold risk of melanoma in patients with RCC, and a nearly threefold risk of RCC in melanoma patients, were found in the review of the International Tumor Registry Database at The University of Texas MD Anderson Cancer Center.

The incidence of subsequent melanomas or RCCs in this study was in line with other recent reports from cancer registry analyses, reported Kevin B. Kim, MD, and his coinvestigators.

“Clinicians should be more watchful for these secondary cancers in patients with a history of melanoma or RCC,” they wrote. The report is in Cancer Epidemiology.

They found a total of 13,879 patients with melanoma and 7,597 patients with RCC in their review. Of those patients, 89 had both a melanoma and an RCC diagnosis. About 30% were first diagnosed with RCC, 61% were first diagnosed with melanoma, and 9% had both diagnoses around the same time.

Among the RCC-first patients, the standardized incidence ratio for developing a second primary melanoma was 2.31 (95% confidence interval, 1.52-3.37; P less than .001), while for melanoma-first patients, for developing a second primary RCC, it was 2.87 (95% CI, 2.16-3.74; P less than .001).

Those statistics were consistent with other registry reports, according to Dr. Kim and his colleagues, who wrote that the standardized incidence ratios in those studies ranged from 1.28 to 2.5.

In the MD Anderson registry study, nearly one-third of patients with secondary primary melanoma or RCC had a history of additional secondary cancers, according to the researchers. Those diagnoses included nonmelanoma skin cancers, leukemias, prostate cancer, breast cancer, and colon cancer, among others.

That suggested the presence of possible common risk factors that may have included abnormal genetics, though the database lacked the genetic sequencing and family history data to explore that hypothesis further.

“It would be highly desirable to assess germline genetic information on patients and their families, and also somatic gene aberrations in the tumor lesions, in a more systematic way in order to better elucidate the contribution of the genetics in the association between melanoma and RCC,” Dr. Kim and his colleagues said.

They reported that they had no conflicts of interest.
