Radiation Could Make Mesothelioma Immunotherapy More Effective

Doctors at the Princess Margaret Cancer Center in Toronto are studying the use of hypofractionated radiation to increase the effectiveness of immunotherapy for patients with mesothelioma. They are expected to launch soon a clinical trial that will add an immunotherapy combination to the high-dose radiation and aggressive surgery mix that has been so successful in Toronto. “There are a lot of questions that still need to be answered, but if I was a betting man, I’d lay odds on it [working well],” Dr. John Cho of the cancer center’s clinical research unit, told The Mesothelioma Center at Asbestos.com. “It’s all very promising.” Cho has been working closely with thoracic surgeon and mesothelioma specialist Dr. Marc de Perrot at Toronto General Hospital. Perrot was the lead author of an editorial published recently by the Journal of Thoracic Disease, suggesting the radiation and immunotherapy combination could become standard of care for pleural mesothelioma patients. “Our group demonstrated that non-ablative, hypofractionated radiation can also have a major impact on the immune system in mesothelioma,” Perrot wrote. “Hence, the combination of non-ablative hypofractionated radiation with targeted immunotherapy is a promising strategy for the near future in mesothelioma.” SMART Evolves into SMARTER The research team in Toronto is continuing to build on its unconventional Surgery for Mesothelioma After Radiation Ther...

Authors: Musio F Abstract INTRODUCTION: Anemia has and will continue to be a central theme in medicine particularly as clinicians are treating a burgeoning population of complex multi-organ system processes. As a result of multiple randomized controlled trials (RCTs), meta-analyses, and societal recommendations overly restrictive paradigms and under-administration of erythropoiesis stimulating agents (ESAs) have likely been followed by clinicians among all specialties. AREAS COVERED: A review of anemia in the context of chronic kidney disease, hematologic malignancies and cancer is presented with focus on the e...

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...

Authors: Leprieur EG, Jablons DM, He B Abstract The Sonic Hedgehog (Shh) pathway is physiologically involved during embryogenesis, but is also activated in several diseases, including solid cancers. Previous studies have demonstrated that the Shh pathway is involved in oncogenesis, tumor progression and chemoresistance in lung cancer and mesothelioma. The Shh pathway is also closely associated with epithelial-mesenchymal transition and cancer stem cells. Recent findings have revealed that a small proportion of lung cancer cells expressed an abnormal full-length Shh protein, associated with cancer stem cell features...

The Moffitt Cancer Center in Tampa has opened a mesothelioma clinical trial involving an anti-cancer enzyme drug showing unprecedented success with the most difficult disease subtypes. Patients with sarcomatoid and biphasic histology — the most treatment-resistant subtypes of mesothelioma — can now enroll in a phase 2/3 clinical trial involving the effectiveness of ADI-PEG 20 (pegylated arginine deiminase) in combination with standard chemotherapy. Thoracic surgeon Dr. Jacques Fontaine, director of the Mesothelioma Research and Treatment Center at Moffitt, told Asbestos.com that he and fellow investigators are ...

The goal of surgery in the multimodal treatment of pleural malignancies such as malignant pleural mesothelioma (MPM) or Non-small cell lung cancer with pleural spread (p-NSCLC) is to achieve a macroscopic compete resection (MCR). We have investigated the use of intraoperative photodynamic therapy to reduce the rate of local recurrence following MCR using a variety of photosensitizers, including porfimer sodium and HPPH. With lung sparing MCR and intraoperative PDT, patients with locally advanced, epithelial MPM experience median overall progression free and overall survival of 13 and 36 months, respectively.
