Advances in cancer immunotherapies.

Therapeutic modalities that engage the immune system to recognize and eliminate cancer, known as cancer immunotherapy, has emerged as a distinct pillar of cancer therapy. Among the most promising treatment approaches are therapeutic vaccines, immune checkpoint blockade, bispecific T-cell engagers (BiTEs) and adoptive cell therapies. These approaches share a common mechanism of action, which is elicitation of a T-cell-based immune response, either endogenous or engineered, against tumor antigens, but interactions between the innate immune system, particularly antigen-presenting cells, and immune effectors also underlie the efficacy of cancer immunotherapies and approaches engaging these cells are also under development.
