Adoptive cell transfer as personalized immunotherapy for human cancer

Abstract

Adoptive cell therapy (ACT) is a highly personalized cancer therapy that involves administration to the cancer-bearing host of immune cells with direct anticancer activity. ACT using naturally occurring tumor-reactive lymphocytes has mediated durable, complete regressions in patients with melanoma, probably by targeting somatic mutations exclusive to each cancer. These results have expanded the reach of ACT to the treatment of common epithelial cancers. In addition, the ability to genetically engineer lymphocytesto express conventional T cell receptors or chimeric antigen receptors has further extended the successful application of ACT for cancer treatment.
