Gene therapy self destruct in the treatment of cancerWhen combined with chemotherapy, a new treatment called "gene therapy self destruct" successfully destroyed the prostate tumor cells, protect patient safety.A long-term clinical trials by the Group of experts of the Methodist Hospital, Houston (USA) gave promising results, according to which a combination chemotherapy with gene therapy may provide a more effective treatment in cases of prostate cancer in men. In gene therapy, which self-destruct is defined as a process of intervention genetic genes in malignant prostate cells, so they emit a signal forcing the immune system to attack and destroy.The researchers of the hospital Houston have used a combination of two therapies for the treatment of 66 patients with prostate cancer from 1999 to 2003. Patients were divided into two groups, based on the severity of the cancer. The lighter was treated with chemotherapy, while the heavier group receiving both chemotherapy and hormone therapy. And both groups are testing gene therapy self destruct. Specifically, the doctors decided to apply this therapy two times for the first team, and the rest are over 3 times the therapist. Very satisfactory results for both groups. Lighter disease groups have survival rates up to 97%, while more serious chance of surviving well up to 94%. If compared with the current treatment processes, the new approach for better results from 5 to 20%, according to the report on the specialized san Journal of Radiation Oncology.To activate the self-destruct mechanism of malignant cells, groups of specialists had to use a combination of many viruses. In it, the adenovi, the same as the virus causing the disease, are used to insert genes of a virus that causes Herpes in straight cells. "When genes of herpes virus was brought into cancer cells, they begin to launch the production process of the yeast TK (thymidine kinase), for patients taking the drug against herpes, commonly known as valacyclovir," according to Brian Butler, Chief of radiation oncology at the Houston hospital. This combination attack of herpes virus DNA, and tumor cells created TK was up self destruction mechanism, so that is the reason why this process is named the gene therapy itself.This strategy also works by connecting the body's immune system to the presence of the tumor cells, encouraging the body to deploy an extensive general strike. "We have created a vaccine based on the cancer cells of the patient's own, an additional treatment and may even strengthen even further the level of effect that we can achieve for radiation therapy and hormone", according to Dr. Butler. For his part, head of the research group Bin Teh, Deputy Head of radiation oncology for that gene therapy will soon be available in biodegradable applications and become popular treatments in the future.
