Abstract

Immunotherapy is based in reactivating the patient immune system specifically against the neoplasia, tumors have immunosuppression mechanisms that allow them to control and evade the immune response.

There are different immunotherapy approaches like tumor-targeting monoclonal antibodies, adoptive T cell transfer, anticancer vaccines, checkpoint inhibitors, most of these in important clinical trials in which the effects and toxicities are still evaluated. They are also beginning tested on a combination of immunotherapies and other non-immunological therapies in order to increase the survival of patients. Immunotherapy is still a young area and it needs to reach its peak, but it will surely be a great tool to treat and cure cancer.
