PURPOSE OF REVIEW: Despite aggressive treatment based on definitive chemoradiotherapy, 5-year overall survival in unresectable stage III nonsmall cell lung cancer remains poor (15-20%). The novel immunotherapy based on immune checkpoint inhibitors (ICIs) presents as the therapeutic 'Holly Grail' in lung cancer treatment. RECENT FINDINGS: Preclinical models provide evidence of immunotherapy-radiotherapy (IM-RT) synergy. The exposure to ionizing radiation turns tumor in an in-situ vaccine, primes the innate immune system, increases immunotherapy efficacy by overcoming the immunosuppressive microenvironment of immune-resistant tumors and promotes a systemic, out-of-field antitumor T-cell-mediated response called abscopal effect...
