Abstract
Adoptive T cell therapy (ACT) is the most efficiently used treatment for patients with metastatic melanoma. It is a therapy where a patient’s T cells are collected and proliferated to a very huge number in the laboratory to be reinserted again into his body to be able to recognize and kill these tumor cells. In recently conducted clinical trials, the use of increasing concentration of lymphodepletion before infusion of autologous tumor infiltrating lymphocytes (TIL) displayed response rates of 49% to 72%. Responses occur at all sites of tumor antigen and appear to be tolerated with many patients in ongoing duration beyond three years. In the latest trial, patients receiving maximum amount of lymphodepletion, 4 of the 25 patients enrolled …show more content…
Patients with melanoma usually have 10% - 15% rate of survival which is about 8 months to 2 years. The first and most applicable treatment is a surgery to eradicate the present tumor. Recently, the US Food and Drug Administration has approved two melanoma treatments; interlukin (IL)-2 and dacarbazine.
Adoptive cell therapy is concerned as the most effective treatment to patients with metastatic melanoma. This therapy involves the transfer of autologous tumor- infiltrating lymphocytes; white blood cells that moved from bloodstream into a tumor; after lymphodepleting chemotherapy. Adoptive cell therapy (ACT) used tumor antigen-specific lymphocytes that were cultured in vitro from single cell enzymatic pieces or small fragments of resected tumor sample and proliferated them to large numbers before infusion into humans. Tumor infiltrating lymphocytes from melanoma wounds hold a variety of tumor antigen reactive cells. The isolation and expansion of tumor antigen reactive cells to large numbers have made ACT therapy more applicable. In our prior clinical trial, patients had obtained a lymphodepleting, nonmyeloablative (NMA) chemotherapy
