This document discusses the management of locally advanced lung cancer. It provides information on the epidemiology, risk factors, anatomy, patterns of spread, diagnostic workup, staging, and management approaches for resectable stage III disease. Management involves induction chemotherapy or chemoradiation followed by surgery with postoperative radiotherapy or chemotherapy, depending on pathological findings. The evidence from clinical trials supports the use of multimodality therapy with chemotherapy and radiation for improved outcomes in resectable locally advanced non-small cell lung cancer.
