Combining Immunotherapy with Radiation Therapy in Non-Small Cell Lung Cancer.

Immune checkpoint inhibitors have recently been demonstrated to improve survival in metastatic and locally advanced non-small cell lung cancer (NSCLC). Radiation therapy has a well-established role in the treatment of NSCLC and has more recently been shown to be immunostimulatory, with the potential to enhance the efficacy of immunotherapy. This comprehensive review details the current roles of radiation therapy and immune checkpoint inhibitors in NSCLC, discusses the intersection of these two modalities and their potential to have combined synergistic responses, and highlights existing preclinical and clinical data and ongoing clinical trials of combined immunotherapy and radiotherapy across all NSCLC stages.
