Adoptive T-Cell Therapy of Cancer

Adoptive therapy involves the transfer of ex vivo expanded immune effector cells to patients as a means of augmenting the antitumor immune response. In general, this transfer is accomplished by harvesting cells from the peripheral blood, tumor sites, or draining lymph nodes and expanding effector cells in a specific or nonspecific fashion for adoptive transfer. This article describes the rationale for adoptive T-cell therapy, the developments that have led to the translational application of this strategy for the treatment of cancer, the challenges that have been addressed, and future approaches to the development of adoptive therapy as a treatment modality.
