Abstract
Management of stage II-III non-small cell lung cancer (NSCLC) has been dramatically revolutionized by studies testing the addition of immunotherapy (IO) to chemotherapy in the pre- or perioperative setting. That is because the integration of chemoimmunotherapy (chemo-IO) with surgery has consistently shown a significant improvement in pathological complete response (path CR) rate, event-free survival, and, more recently, overall survival, versus preoperative chemotherapy alone. Particularly, resectable stage III NSCLCs represent a disease entity with a high risk of distant recurrence after radical surgery, for whom pre- or perioperative chemo-IO should be considered as the preferential treatment option. However, owing to the heterogeneity of stage III NSCLC, a standard definition of resectability is not established yet, being often subjective according to the expertise and clinical background of the thoracic surgeon. In addition, careful patient selection on the basis of tumor biomarkers, meticulous staging of the disease, and accurate monitoring of treatment-related adverse events are critical factors that could prevent the ineligibility for surgery of patients treated with pre- or perioperative chemo-IO. Finally, the impact of downstaging for initially borderline resectable tumors, as well as the exact number of preoperative chemo-IO cycles needed and the indications for adjuvant IO, still need to be fully elucidated. In this podcast, we will touch upon the above-mentioned topics from the perspectives of the thoracic surgeon and the oncologist, and suggest a shared agreement between two of the main actors involved in the treatment of resectable stage III NSCLCs.Podcast audio available for this publication.
