[Perioperative immunotherapy for non-small cell lung cancer: consensus and controversy (2024 edition)].

Lung cancer is the malignant tumour with the highest morbidity and mortality rate in China, among which non-small cell lung cancer (NSCLC) is the main pathological type of lung cancer, accounting for about 80% to 85%. Radial surgery is the standard treatment for early-stage NSCLC, but postoperative recurrence is an inevitable problem in clinical practice. Adding perioperative chemotherapy to surgery can only increase the 5-year overall survival rate by about 5%. There is an urgent need for better systemic treatments. In recent years, immunotherapeutic drugs, represented by PD-1/PD-L1 monoclonal antibodies, have brought breakthroughs from subsequent-line treatment to front-line treatment for NSCLC. Several Phase III studies on perioperative immunotherapy have shown that adding immunotherapy during the neoadjuvant and adjuvant treatment can significantly improve survival outcomes for patients, leading to the development of a new standard treatment for resectable NSCLC. In January 2024, the first PD-1 monoclonal antibodies (Toripalimab) were approved for perioperative treatment of NSCLC in China, starting a new era of perioperative immunotherapy. At present, there is still a lack of unified consensus on the application of perioperative immunotherapy at all levels of medical institutions. In order to privide diagnostic and treatment guidance for clinicians, promote the standardization of clinical practice for immunotherapy in resectable NSCLC, and clarify the controversial opinions regarding perioperative immunotherapy, Lung Cancer Expert Committee of the Chinese Anti-Cancer Association, Chinese Thoracic Oncology Group, Lung Cancer Expert Committee of the Chinese Medical Association Oncology Society jointly published this Consensus and Controversy to provide a guidance for the standardized management of perioperative immunotherapy for NSCLC.
