Immunotherapy - one of the newest and most effective cancer treatments , which has been successfully used at any stage of the disease. The method - to force the immune system to fight the disease. The impact takes place only on the tumor cells without damaging healthy tissue. Therefore, the side effects of this treatment are minimized.
In the initial stages of cancer, 1 st and 2 nd, immunotherapy is used as an additional treatment, but patients with the 3rd and 4th stages of the disease, it is the only possible way.
Immunotherapy in onkologiiMeditsinskaya science does not stand still. The latest research by American scientists, the results of which were announced on February 14, 2016 at the annual gathering of the American Association for the Advancement of Science (AAAS) in Washington, prove it. A recently developed a new type of immunotherapy, which is superior to the results of all available methods of treatment.
The experiment involved patients with acute lymphoblastic leukemia, chronic lymphocytic leukemia and non-Hodgkin's lymphoma, are on the 3rd and 4th stages of the disease.
Isolated from the blood of subjects T-lymphocytes. With embedded inactive lentivirus gene in chimeric DNA lymphocyte antigen receptor. This receptor signaling protein contains the domain required for the survival of T-cells, as well as protein, connecting with the receptors of tumor cells and has immunostimulatory and anti-cancer properties
The new cells are introduced intravenously to patients once with the possibility of re-introducing 21 days at an unsatisfactory result. Within a few weeks, 27 of 29 patients with acute lymphoblastic leukemia tests showed no cancer cells, and 19 of 30 patients with non-Hodgkin's lymphoma is almost entirely recovered.
The main side effects of therapy were strong chills, fever, and decreased blood pressure. But after the correction cell portion in subsequent experiments that managed to escape.
Scientists continue to work on improving the method of using genetically engineered T-lymphocytes and adapt it to use in the treatment of other types of malignant tumors breast and lung cancer
Stanley Riddell , one of the authors, said: "The combination of synthetic biology, gene therapy and cell biology offers the chance of cure for patients with treatment-resistant tumors and it represents a new type of treatment that can transform an oncology. »
This is great news for the tens of thousands of cancer patients, it gives hope for recovery and long life. Share this article with your friends!
