Immune checkpoint inhibitors (ICIs) are swiftly transitioning from the metastatic to early-stage settings and are expected to transform the multimodal management of patients with resectable stage I-III NSCLC. Remarkable data have emerged from several trials assessing ICIs and rational combinations as neoadjuvant and/or adjuvant therapies, but many questions remain and misperceptions persist. What are the pros/cons of neoadjuvant versus adjuvant immunotherapy, and how should the best approach be determined for each patient? What is the optimal duration of therapy, and how should responses be assessed? What adverse events should be anticipated, and are perioperative complications higher? This PeerView MasterClass, based on a recent live web broadcast, addresses these and many other essential topics. Watch this engaging discussion about new, practice-changing evidence, debates about implications and applicability to practice, and demonstrations of how to achieve better surgeon–oncologist partnerships to facilitate appropriate incorporation of ICIs into multimodal treatment plans for patients with stage I-III NSCLC. Upon completion of this CE activity, participants will be able to: Describe the mechanistic aspects of immune checkpoint inhibition, rationale for using immunotherapy as a component of multimodal therapy in earlier stages of lung cancer, and key clinical trials evaluating immunotherapy in these settings, Assess the real evidence and misconceptions related to the safety and adverse effects of checkpoint inhibitors when used in the treatment of patients with locally advanced and early-stage lung cancer as well as potential implications for surgical outcomes in these patients, Apply the latest evidence and guidelines for integrating immunotherapy into multimodal treatment plans in locally advanced and earlier stages of NSCLC, Collaborate with the multidisciplinary team to develop evidence-based, individualized treatment approaches for patients with stage III or earlier lung cancer in the context of clinical practice or clinical trials.
