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.
