DNA Therapies Could Give Promising Mesothelioma Treatments Compared to Radiation Therapy
Posted by admin under The Science Way , Health InfosCancer doctors decide what type of treatment to pursue with a patient. There are many options. There are no standard treatment option for mesothelioma 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. Customary treatments for cancer are surgery (removing the tumor and the tissue that surrounds it), 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. 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 combinations of chemotherapy agents have been tried, but without much success. Similar to radiation, focus in research is focusing on treating the physical location of the tumor with emphasis on the pleural cavity.
Many advanced techniques in cancer treatment are tried on mesothelioma patients because of its high fatality rate. 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).
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. Clinical trials using these techniques are being offered to some of those who have mesothelioma.
