Immunotherapy for Lung Cancer.

Immune evasion is recognized as a key strategy for cancer survival and progression. Hence, various approaches to restore antitumor immune responses are currently being investigated. In particular, agents targeting immune checkpoints, such as the cytotoxic T-lymphocyte-associated antigen-4 receptor and programmed death-1 receptor, have shown potential for improving tumor responses and survival in lung cancer patients. With the first immunomodulating agents having been approved for treatment of selected lung cancer patients, there are high expectations that treatment outcomes may be improved with the incorporation of immunotherapies into the various treatment cascades.
