Oklahoma doctors on Wednesday unveiled what they call a revolutionary new treatment for cancer patients. The treatment harnesses the body바카라 게임 웹사이트�s own immune cells to fight tumors, and it will be offered starting Thursday at the Stephenson Cancer Center at OU Medicine.CAR T-cell therapy has been approved by the Food and Drug Administration. Officials said its initial use is for two different blood cancers, one affecting children and the other affecting adults. 바카라 게임 웹사이트�CAR T is a major breakthrough for patients who have not improved with standard treatments,바카라 게임 웹사이트� said Dr. George Selby, director of the Transplant and Cellular Therapy Program at the Stephenson Cancer Center. 바카라 게임 웹사이트�It is an immune therapy in which we바카라 게임 웹사이트�re harnessing our own cells to recognize cancer cells. That바카라 게임 웹사이트�s what a normal immune system does 바카라 게임 웹사이트� it acts in a surveillance capacity so that when a malignant cell arises, it is killed by our immune system. CAR T is a way of rebooting the immune system when it has failed.바카라 게임 웹사이트�CAR T initially will be used to treat advanced lymphomas in adults. In the coming months, physicians anticipate offering similar treatment for acute lymphoblastic lymphoma in children and young adults. In both cases, patients must have failed to respond to standard chemotherapy or stem cell transplant.CAR T stands for Chimeric Antigen Receptor T-cell therapy. Patients being treated with CAR T will first have their blood collected at the Oklahoma Blood Institute in a process that is similar to a typical blood donation. T cells, a type of white blood cell involved in immunity, are filtered out and the plasma and red cells are returned to the patient. The T cells are then sent to a company that injects them with the gene for a chimeric antigen receptor, which is known to bind itself to cancer cells and activate the T cell, according to officials with the hospital. This process allows the newly engineered T cells to recognize and attack cancer with remarkable efficiency. Once the CAR T cells are generated, they are shipped back to the Stephenson Cancer Center and given to the patient through an IV, much like a blood transfusion, officials said. 바카라 게임 웹사이트�Until the advent of CAR T, if a patient바카라 게임 웹사이트�s tumor came back after a stem cell transplant, their options were very limited, if they existed at all,바카라 게임 웹사이트� Selby said. 바카라 게임 웹사이트�This is a major breakthrough for those patients for whom standard treatment has not been successful.바카라 게임 웹사이트�Unlike other types of cancer therapies, CAR T is a one-time treatment, officials said. The T cells remain in the body and, if the cancer comes back, the cells reactivate to attack the tumors.바카라 게임 웹사이트�These T cells go on to kill hundreds to thousands of tumor cells; the nickname for these cells is 바카라 게임 웹사이트�serial killers,바카라 게임 웹사이트�바카라 게임 웹사이트� said Dr. Adam Asch, deputy director of the Stephenson Cancer Center and chief of the Division of Medical Oncology and Hematology.Using the immune system to fight cancer has been the holy grail for oncologists, Asch said. 바카라 게임 웹사이트�The research data that led to the approval of CAR T has been extraordinary,바카라 게임 웹사이트� Asch said. 바카라 게임 웹사이트�This therapy appears to be long-lasting in a high percentage of these patients.바카라 게임 웹사이트�According to officials, clinical trials are underway studying the effectiveness of CAR T in treating other blood cancers, including multiple myeloma, as well as solid tumors. Another trial will study the effectiveness of CAR T as compared to transplant; CAR T potentially could move ahead of transplant as a treatment because of its ability to use the patient바카라 게임 웹사이트�s own immune system rather than someone else바카라 게임 웹사이트�s. The Stephenson Cancer Center will be participating in several such clinical trials.
