Photodynamic Therapies May Offer Better Treatment for Mesothelioma than Chemotherapy

Cancer doctors determine what type of treatment to pursue to each patient. There are many options. There are no regular treatment option for mesothelioma cancer victims. Mesotheliomas lack of agreed-upon treatment is due to low a treatment success rate, rareness, a high mortality rate and a small number of studies providing meaningful stats.
Mesothelioma patients have historically had a bleak outlook, but doctors have recently made progress. Traditional treatments for cancer are surgery (removing the tumor and surrounding tissue), chemotherapy (poisoning cancerous cells) and radiation (killing cancer cells with radiation) 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 takes out the mesothelial cancerous tissue around the tumor. This surgery is extensive and it is not clear how much the patient benefits. The usual chemotherapy cocktails effective on other cancers are not effective on mesothelioma, and combinations of chemotherapy agents have been tried, but without much 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. The new drug pemetrexed (brand name Alimta) has shown good results in extending life with mesotheliomas..
Oncologists consider the stage of mesothelioma, the location of the tumor, the patient’s age and state of health at the time. Two exotic ways of attacking mesothelioma are gene therapy and photodynamic therapy. Patients afflicted with mesothelioma are benefitting in these clinical trials.
