Photodynamic Therapies May Give Better Treatment for Mesothelioma than Chemotherapy

Oncologists and other cancer doctors decide what type of treatment to prescribe with each patient. There are many options. There is no regular treatment option for asbestos cancer sufferers. This is due to the cancers high mortality rate, rareness, low treatment success rate, and small number of studies to provide meaningful statistics.

Mesothelioma patients have historically had a bleak outlook, but doctors have recently made progress. Treatments for cancer are traditionally surgery (taking out the tumor and surrounding tissue), chemotherapy (poisoning cancerous cells) and radiation (killing cancer cells with radiation) Each one of these methods have problems. Traditional radiation therapy has not worked well with mesothelioma patients. Researches, concerned about damage to healthy tissue, are looking for ways to aim radiation directly at tumors.

Surgery takes out the mesothelial cancerous 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. Similar to radiation, focus in research is focusing on treating the physical location of the tumor with 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. Pemetrexed (Alimta) is a new drug that has shown results in extending life.

Considered by oncologists is where the tumor is located, what stage the mesothelioma is in, and the age and health 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.
