ABSTRACT
Cancer immunotherapy comprises different therapeutic strategies that exploit the use of distinct components of the immune system, with the common goal of specifically targeting and eradicating neoplastic cells. These varied approaches include the use of specific monoclonal antibodies, checkpoint inhibitors, cytokines, therapeutic cancer vaccines and cellular anticancer strategies such as activated dendritic cell (DC) vaccines, tumor-infiltrating lymphocytes (TILs) and, more recently, genetically engineered T cells. Each one of these approaches has demonstrated promise, but their generalized success has been hindered by the paucity of specific tumor targets resulting in suboptimal tumor responses and unpredictable toxicities. This review will concentrate on recent advances on the use of engineered T cells for adoptive cellular immunotherapy (ACI) in cancer.
