Radiation Therapy Do Little to Help Mesothelioma Patients, However Photodynamic Therapy Offers a Promising Alternative
11 06 2009Oncologists determine what kind of treatment to pursue for a patient. There are many options. There exists no regular treatment regimen for peritoneal mesothelioma cancer victims. This is due to the cancers high mortality rate, rareness, low treatment success rate, and small number of studies to provide meaningful statistics.
The prospects for mesothelioma patients have been grim, but doctors have recently made progress. Treatments for cancer are traditionally surgery (taking out the tumor and surrounding tissue), radiation (killing the cancerous cells with radiation), and chemotherapy (poisoning the cancerous cells.) Each one of these methods have problems. Patients with mesothelioma have not responded well to traditional radiation therapy. In hopes to lessen damage to healthy tissue, researches are studying ways to aim radiation right at the tumor.
Surgery removes the mesothelial tissue around the tumor. This surgery is extensive and it is not clear how much the patient benefits. Most chemotherapy medication that work on other cancers typically do not work on mesothelioma, and different combinations of chemotherapy drugs have been tried without a lot of success. Like radiation, researchers are focusing their work on controlling the physical location of the treatment with an emphasis on the pleural cavity.
The death rate for mesothelioma is so high that many of even the most sophisticated techniques in cancer treatment are tried out on patients. Such treatments include anti-angiogenesis drugs like thalidomide and biologic therapies agent interleukin 2. A new drug that has shown results in improving survival is pemetrexed (brand name Alimta).
Before acting, oncologists review the stage of mesothelioma, position of the tumor, and age and health status of the patient. Two therapies that are extremely cutting-edge in fighting cancer are called photodynamic and gene therapy. Patients afflicted with mesothelioma are benefitting in these clinical trials.
