The Evolving Role for Systemic Therapy in Resectable Non-small Cell Lung Cancer

During the last 2 decades, the understanding of non-small cell lung cancer (NSCLC) has evolved from a purely histologic classification system to a more complex model synthesizing clinical, histologic, and molecular data. Biomarker-driven targeted therapies have been approved by the United States Food and Drug Administration for patients with metastatic NSCLC harboring specific driver alterations in EGFR , HER2 , KRAS , BRAF , MET , ALK , ROS1 , RET , and NTRK. Novel immuno-oncology agents have contributed to improvements in NSCLC-related survival at the population-level. However, only in recent years has this nuanced understanding of NSCLC permeated into the systemic management of patients with resectable tumors.
