With the acceleration of population aging in China, the number of elderly patients with lung cancer continues to rise. These patients not only face threats from the tumor itself but also often suffer from multiple chronic diseases and geriatric syndromes, which increase the complexity of perioperative management and surgical risks. To provide standardized perioperative management strategies for elderly lung cancer patients, the guideline aims to reduce postoperative complications and improve patients' quality of life through comprehensive geriatric assessment, comorbidity management, and early identification and intervention of complications. The guideline working group has drafted the "Protocol for Guidelines on the Comprehensive Perioperative Management of Elderly Patients with Lung Cancer (2025)", detailing the development process of the guidelines.
