Lung cancer is the malignant tumor with the highest incidence and mortality rate in China, which seriously threatens the life and health of Chinese people. Locally advanced unresectable non-small cell lung cancer is characterized by high heterogeneity and poor prognosis, and durvalumab consolidation therapy after concurrent chemoradiotherapy is the main treatment modality. In recent years, advances in targeted therapies and immunotherapy have changed the treatment landscape of lung cancer. A portion of locally advanced or advanced non-small cell lung cancer that was initially unresectable is down-staged and converts to surgically operable radical resection after comprehensive treatment, and this surgical treatment strategy is called conversion surgery. With the progress of comprehensive treatment modalities, it may occupy an increasing proportion in thoracic surgery in the future. This article reviews the treatment modality and conversion surgery for locally advanced unresectable non-small cell lung cancer.
