Better Muscle Mass Linked to Improved Immunotherapy Response

Researchers at Osaka University in Japan have identified a key component of physical health associated with response to immunotherapy drugs. Among people with non-small cell lung cancer, higher levels of muscle mass predicted a better response to PD-1 inhibitor immunotherapy. Sarcopenia — the term used to describe low muscle mass levels — appears to reduce the benefits a person receives from immunotherapy cancer treatment. “Sarcopenia at baseline is a significant predictor of worse outcome in patients with advanced NSCLC [non-small cell lung cancer] receiving PD-1 blockade,” the study investigators wrote. The results, published February 21 in Nature Scientific Reports, highlight the importance of good baseline strength and physical function for mesothelioma patients considering immunotherapy treatments. Immunotherapy is not a standard mesothelioma treatment option. However, there are more than a dozen clinical trials currently investigating PD-1 inhibitor therapy for the asbestos-related cancer. “Screening for sarcopenia may help identify patients more likely to achieve a long-term response in routine clinical practice,” the authors wrote. Strong Body, Stronger Immunotherapy Response Rate Researchers collected information on 42 men and women with non-small cell lung cancer seen at their facility between January 2016 and September 2018. The patients were treated with Opdivo (nivolumab) or Keytruda (pembrolizumab). CT scans available in the ...

Patients with mesothelioma are now eligible for a multicancer clinical trial studying the effectiveness of personalized immunotherapy at the University of California, San Diego Medical Center. The phase I clinical trial involves a combination of Keytruda (pembrolizumab), a proven immunotherapy drug, and an individualized vaccine based upon the genetic mutations found in each patient’s cancer. “This is the future of cancer treatment,” Dr. Ezra Cohen, principal investigator and director of the San Diego Center for Precision Immunotherapy, told The Mesothelioma Center at Asbestos.com. “Now, we still ha...

Abstract Pemetrexed (PMX) is a multi-targeted antifolate drug used for the treatment of malignant pleural mesothelioma (MPM) and non-small cell lung cancer. Hyaluronan (HA) in blood is well known as a disease marker of MPM. We synthesized PMX-conjugated hyaluronan (HA-ADH-PMX) for the first time to develop a novel anticancer chemotherapeutic agent. HAs with different molecular weights (76 and 130 kDa) were first derivatized with adipic dihydrazide (ADH) and then conjugated to PMX. The obtained HA-ADH-PMX retained inhibitory activity against folate metabolism enzymes; thymidylate synthase was inhibited to the sam...

This study quantifies the disturbing trend that, despite the expansion in the number of patients eligible for expensive and potentially toxic ICIs [immune checkpoint inhibitors], the ratio of those benefiting is decreasing,” wrote Dr. Daniel V.T. Catenacci, co-author of an editorial that accompanied the study in JAMA Network. “Observations in this article are sobering and remind us to keep expectations realistic.” Both Catenacci and Haslem agreed that the study should serve as a reminder to patients, physicians and policy makers to have more realistic discussions about the use of, and expectations of, the...

Sarah Cannon Research Institute in Nashville, Tennessee, and MD Anderson Cancer Center in Houston have opened a much-anticipated clinical trial involving a novel T-cell therapy for patients with mesothelioma. The two institutions are establishing dosage levels and measuring efficacy of TC-210, a type of immunotherapy that targets mesothelin, a cell surface protein highly expressed in several cancers. The study also is open to patients with certain types of bile duct, ovarian and non-small cell lung cancer. Participation is based upon individual levels of mesothelin expression. Researchers at the two centers are hoping to ...

Conclusions This review describes how leukocyte-heparanase can be a double-edged sword in tumor progression; it can enhance tumor immune surveillance and tumor cell clearance, but also promote tumor survival and growth. We also discuss the potential of using heparanase in leukocyte therapies against tumors, and the effects of heparanase inhibitors on tumor progression and immunity. We are just beginning to understand the influence of heparanase on a pro/anti-tumor immune response, and there are still many questions to answer. How do the pro/anti-tumorigenic effects of heparanase differ across different cancer types? Does...

This study hypothesized that similar VOCs might be detected after HBOT. Methods: Ten healthy volunteers of the Royal Netherlands Navy underwent six HBOT sessions (95 min at 253 kPa, including three 5-min “air breaks”), i.e., on five consecutive days followed by another session after 2 days of rest. At 30 min before the dive, and at 30 min, 2 and 4 h post-dive, exhaled breath was collected and followed by PFT. Exhaled breath samples were analyzed using gas chromatography-mass spectrometry (GC-MS). After univariate tests and correlation of retention times, ion fragments could be identified using a reference data...

Tumor Treating Fields (TTFields) are a clinically applied anti-neoplastic treatment modality delivered via noninvasive application of low intensity, intermediate frequency, alternating electric fields. This therapy is approved for the treatment of patients with glioblastoma and pilot studies have demonstrated the safety as well as preliminary effectiveness of TTFields application in patients with non-small cell lung cancer and mesothelioma. Here we evaluated the potential of TTFields therapy to induce immunogenic cell death (ICD) and evaluate the efficacy of concurrent application of TTFields and anti-PD-1 therapy in murin...
