Radiation May Help Mesothelioma Immunotherapy Treatment Work Better

mesothelioma radiation treatment

Hypofractionated radiation for mesothelioma could change how doctors treat this rare cancer.  Researchers in Toronto, Canada have been testing hypofractionated radiation in mesothelioma surgery patients. They have used it to shrink tumors before lung-removing EPP surgery. Hypofractionated radiation is faster than than standard radiation. It may also cause fewer side effects. Now, doctors want to know what else this type of radiation might be good for. They plan to test how well hypofractionated radiation works with less radical mesothelioma surgery. There is also evidence that hypofractionated radiation may strengthen mesothelioma immunotherapy treatment. Radiation Before Mesothelioma Surgery Doctors at the Princess Margaret Cancer Center in Toronto ran a clinical trial called SMART. SMART stands for Surgery for Mesothelioma After Radiation Therapy. … Continue reading Radiation May Help Mesothelioma Immunotherapy Treatment Work Better »

Old Drug May Breath New Life Into Mesothelioma Radiotherapy

Researchers at the University of Ohio may have found a way to make radiation therapy more effective for people with mesothelioma and other types of solid tumors. They’re using a muscle relaxant approved in the 1800s to increase the level of oxygen in cancer cells and make them more susceptible to the damaging effects of radiation. The research could have wide-ranging implications, especially for patients fighting treatment-resistant malignancies like pleural mesothelioma. The Limitations of Radiation for Pleural Mesothelioma Mesothelioma is a fast-growing cancer associated with asbestos exposure that occurs on the membranes around internal organs. Although the irregular shape and tricky location of mesothelioma tumors can make them difficult to treat with radiotherapy, advanced targeting techniques are making it more … Continue reading Old Drug May Breath New Life Into Mesothelioma Radiotherapy »

New Study Points to Benefits of IMRT for Mesothelioma Treatment

There is more evidence that mesothelioma patients who have lung sparing surgery can live longer if it’s followed up with highly targeted radiation therapy. In the first study to come out of Israel on the subject, a team of oncologists, pulmonologists, radiation oncologists, and thoracic surgeons at Rabin Medicine Center in Petah Tikva say intensity modulated radiation therapy (IMRT) is safe and effective for slowing down the growth of pleural mesothelioma tumors. The Challenge of Radiotherapy for Mesothelioma The irregularity of malignant mesothelioma tumors makes them difficult to treat with standard external beam radiotherapy without damaging healthy tissue and causing serious side effects. This is particularly problematic in patients who still have both lungs, either because they were not good … Continue reading New Study Points to Benefits of IMRT for Mesothelioma Treatment »

Radiotherapy LIkely to Play a Bigger Role in Future Mesothelioma Therapy

New research suggests that radiotherapy is likely to play a larger role in the multi-modal treatment of malignant pleural mesothelioma in the future, supporting and enhancing treatments such as surgery and immunotherapy. Radiation scrambles the DNA inside cancer cells, interrupting their life cycle and making replication impossible. If it were possible to irradiate only mesothelioma cells without affecting the surrounding healthy tissue, radiotherapy might even be able to cure cancers like mesothelioma. But as the authors of a new study published in the Journal of Thoracic Disease point out, until recently, radiotherapy has been of limited use in the treatment of mesothelioma because it hasn’t been precise enough. Thanks to new technology, that is changing. Why Mesothelioma is Hard to … Continue reading Radiotherapy LIkely to Play a Bigger Role in Future Mesothelioma Therapy »

Mesothelioma Survival Improves with Post-Surgery Radiation

Pleural mesothelioma patients who undergo radiotherapy after their surgery tend to live longer than those whose treatment plan does not include radiation. Unfortunately, only a small percentage of patients who could stand to benefit from this treatment actually get it. Researchers at Houston Methodist Hospital, Baylor, and The University of Texas have come to that conclusion after analyzing data from the National Cancer Database on nearly 25,000 patients with malignant pleural mesothelioma from 2004 to 2013. It was the largest study of adjuvant radiotherapy for mesothelioma ever conducted. Radiotherapy in Mesothelioma Treatment Although radiotherapy is not routinely used in mesothelioma treatment, when it is used, it is typically either palliative as a way to relieve symptoms, or as an add-on … Continue reading Mesothelioma Survival Improves with Post-Surgery Radiation »

Radiation for Mesothelioma: Could Proton Therapy Be the Answer?

Researchers at the Maryland Proton Therapy Treatment Center say a highly-targeted version of proton beam radiation could be the future of radiotherapy for malignant pleural mesothelioma. In a new journal article, doctors at the center detail the evolution of radiation treatment for pleural mesothelioma, from standard photon-based therapy to targeted proton therapy. “Radiation therapy has historically been used [for mesothelioma] only in the palliative setting or as adjuvant therapy after extrapleural pneumonectomy,” notes the report. But the researchers go on to say that radiotherapy advances such as intensity-modulated radiation therapy (IMRT) and a more precise form of proton beam therapy called pencil-beam scanning, are changing the value of radiotherapy for mesothelioma patients. Radiation’s Role in Pleural Mesothelioma Treatment Radiation works … Continue reading Radiation for Mesothelioma: Could Proton Therapy Be the Answer? »

Experimental Mesothelioma Therapy Shrinks Mouse Tumors by 80 Percent

An innovative approach to mesothelioma treatment being developed in Italy has produced results researchers call “very promising”. The treatment reduced the size of mesothelioma tumors in  mice by 80 to 85 percent in just over a month. Noninvasive image-guided Boron Neutron Capture Therapy (BNCT) utilizes the unique properties of boron to destroy mesothelioma cells from the inside out. It has been used as an alternative to conventional radiation therapy for the treatment of malignant brain tumors and recurrent head and neck cancers. The new Italian study is the latest to evaluate this approach for patients with malignant mesothelioma, a hard-to-treat membrane cancer caused by exposure to asbestos. Boron Neutron Capture Therapy for Mesothelioma BNCT is a two-step cancer treatment approach. … Continue reading Experimental Mesothelioma Therapy Shrinks Mouse Tumors by 80 Percent »

Hard-to-Find Therapy Fights Mesothelioma Tumors with Carbon Ions

Carbon ion therapy—a cancer treatment developed in California but currently only available outside the US—may have the ability to significantly slow down the growth and spread of pleural mesothelioma tumors. Researchers at one of the world’s most experienced carbon ion therapy centers in Chiba, Japan shared that conclusion in a new article in the journal Oncotarget. According to the new research, carbon ion beams directed at two lines of malignant mesothelioma cells in the lab “suppressed cell viability”. The addition of cisplatin, one of two primary chemotherapy drugs used in the treatment of mesothelioma around the world, “significantly enhanced its action.” The news is likely to be both exciting and frustrating for American mesothelioma patients who do not yet have … Continue reading Hard-to-Find Therapy Fights Mesothelioma Tumors with Carbon Ions »

New Technology Could Change How Mesothelioma Treatment is Monitored

New technology could eventually make it easier, less painful, and less expensive to track the progress of patients undergoing treatment for malignant mesothelioma and other cancers. A research team led by University of Wisconsin-Madison pharmacy professor Seungpyo Hong has developed what they say is a more efficient method for capturing free-floating cancer cells in the blood. The developers say the system is far more effective than existing systems at capturing these hard-to-find circulating tumor cells (CTCs) and could be used to supplement other technologies for tracking cancer treatment. Mesothelioma Biopsy vs CTC Tracking Although mesothelioma therapies have advanced in recent years, there is still no cure for the asbestos-linked cancer. As scientists work to develop new kinds of treatments like … Continue reading New Technology Could Change How Mesothelioma Treatment is Monitored »

New Mesothelioma Treatment Combines Immunotherapy and Targeted Radiation

Researchers at one of the nation’s top cancer institutes are betting on a combination of radiation and immunotherapy in the continued pursuit of better treatments for malignant mesothelioma. Memorial Sloan Kettering in New York is now recruiting relapsed mesothelioma patients into a safety and efficacy study of stereotactic body radiation therapy (SBRT) and the immunotherapy drug avelumab. The new trial is based on the idea that radiation may boost the immune system’s anti-mesothelioma response and that avelumab may enhance the effect. “The combination of radiation therapy and immunotherapy may be more effective against mesothelioma than either treatment alone,” writes lead researcher and radiation oncologist Andreas Rimner, MD, in a summary of the new study. SBRT in Mesothelioma Treatment The first … Continue reading New Mesothelioma Treatment Combines Immunotherapy and Targeted Radiation »
