IMRT for Long-Term Survival After Mesothelioma Surgery

Intensity modulated radiation therapy (IMRT) can safely slow or even stop mesothelioma progression after surgery as long as the dose is just right. A team of Texas radiation oncologists reached that conclusion after studying the treatment results of 18 mesothelioma patients between 2005 and 2014. IMRT is a highly targeted form of high-dose radiation. While it can have a powerfully negative effect on tumor cells, it can also have an equally negative effect on healthy lung tissue. Some patients have even died from pulmonary toxicity caused by IMRT. But in a report published in the journal Oncology, doctors from Texas A & M Medical Sciences Center and Baylor Scott and White Hospital found that, as long as the radiation dose … Continue reading IMRT for Long-Term Survival After Mesothelioma Surgery »

Radiotherapy for Mesothelioma: Better But Still Limited

radiologist

A form of highly-targeted radiation therapy for mesothelioma is better than it used to be, but is still risky. That is the message of a recent article on intensity-modulated radiation therapy (IMRT) in Seminars in Thoracic and Cardiovascular Surgery. Author Kenneth E. Rosenzweig, MD, a Radiation Oncologist with Mount Sinai Hospital in New York, reviewed recent studies on IMRT and mesothelioma. He concludes that, while the “troubling toxicity” associated with IMRT when it was first introduced has not been entirely eliminated, the fact that clinicians now have more experience with it is making a positive difference for mesothelioma patients. Before targeted therapies like IMRT were available, high-dose radiation was not usually a feasible option for mesothelioma since the irregular shape … Continue reading Radiotherapy for Mesothelioma: Better But Still Limited »

Mesothelioma Outcomes May Be Improved by New Radiation Therapy

There is evidence that a new type of radiation therapy may have advantages over other methods for treating mesothelioma patients after surgery. A marriage of spiral CT-scanning technology and intensity modulated radiation therapy (IMRT), helical tomotherapy offers enhanced precision and the ability to ‘sculpt’ the radiation dose to conform to the size and shape of the tumor being treated. Because mesothelioma tumors tend to be irregular in shape and spread out across the membranous mesothelial tissue, this sculpting ability may help doctors deliver just enough post-surgical radiation to kill remaining cancer cells without damaging large numbers of healthy cells. In a recent study on the technology at the University of Paris, a group of French researchers analyzed the treatment outcomes … Continue reading Mesothelioma Outcomes May Be Improved by New Radiation Therapy »

New Treatment for Mesothelioma Highlighted at Conference

Experts from around the globe will be meeting in Barcelona, Spain this month to discuss the benefits of a targeted type of radiation therapy that has shown promise in the treatment of malignant mesothelioma. TomoTherapy is the brand name for an Intensity Modulated Radiation Therapy system designed to deliver high doses of radiation directly into tumor cells, while minimizing the damage to surrounding healthy tissues. The developers of the technology will present 82 new studies of its impact on various cancers, including mesothelioma, at the conference sponsored by the European Society for Therapeutic Radiology and Oncology (ESTRO). Mesothelioma, which involves the lining of the lungs and chest wall, is notoriously difficult to treat with radiation therapy because of the size … Continue reading New Treatment for Mesothelioma Highlighted at Conference »

IMRT Multimodality Therapy for Mesothelioma Appears Safe

Pleural mesothelioma, a malignancy of the lung lining caused by breathing asbestos, is notoriously difficult to treat. While they can improve quality of life, traditional cancer therapies, including chemotherapy, radiation and surgical intervention have not been shown to improve survival rates in most mesothelioma patients beyond a few months. Researchers around the world are experimenting with advanced treatment options that may give mesothelioma patients new hope. A new study on Intensity Modulated Radiation Therapy (IMRT) as part of a multi-modality treatment protocol appears to show improved safety over earlier studies that incorporated the same technology. IMRT is an advanced method of radiotherapy that uses a linear accelerator to deliver precise high doses of radiation directly into a tumor. One of … Continue reading IMRT Multimodality Therapy for Mesothelioma Appears Safe »
