ABSTRACT
The constant advances in the field of lung cancer immunotherapy have recently reached the treatment of locally advanced disease with the approval of durvalumab after concurrent chemoradiation. However, radiation therapy continues to be key for controlling the disease at this stage. Over the years, different strategies have been employed to try to optimize outcomes using radiotherapy, with cardiac and pulmonary toxicity as the main limitation on its success. The interest in the use of hypofractionation and stereotactic body radiation therapy for stage III non-small cell lung cancer has increased as knowledge regarding these kinds of treatments has been enhanced. Hypofractionation is a relatively frequent treatment, although the level of evidence that supports it is limited. For its part, stereotactic body radiation therapy has been particularly studied as a boost after chemoradiation, with encouraging results. In both cases, study of how to integrate these tools with chemotherapy and particularly with immunotherapy is essential, as they may have an immunomodulatory role.
