RESUMO
OBJECTIVE: The objective of this article is to review the efficacy, safety, and evidence for current use and potential future uses of immune-checkpoint inhibitors (ICIs) in the management of resectable non-small cell lung cancer (NSCLC). DATA SOURCES: A literature review was carried out through PubMed to identify completed and ongoing clinical trials evaluating the use, efficacy, and safety of ICIs in the management of resectable NSCLC. DATA SUMMARY: To date, four phase 3 trials have emerged that have changed our treatment practice concerning the utilization of ICIs during the adjuvant and neoadjuvant settings. The IMpower010 and KEYNOTE-091 trials examined the application of adjuvant atezolizumab and pembrolizumab, respectively, following surgical resection and adjuvant chemotherapy. In the CheckMate 816 trial, the combination of nivolumab and chemotherapy as a neoadjuvant therapy received approval for patients with resectable NSCLC. Also, for patients with resectable NSCLC, the use of a pembrolizumab and chemotherapy combination as a perioperative therapy received approval based on the results of the KEYNOTE-671 trial. Apart from these trials, there are numerous phase 2 and phase 3 trials, some of which have been published while others are still in progress. CONCLUSION: Despite the promising outcomes from these trials there remain several unanswered questions. In this review, we will assess clinical trials involving adjuvant, neoadjuvant, and perioperative ICIs, aiming to address the unresolved questions related to these therapeutic approaches.
