流行病学数据显示，肺癌发病率位居恶性肿瘤第2位，死亡率位居恶性肿瘤第1位，2020年约180万例患者死于肺癌。对于晚期肺癌患者，驱动基因的发现及相应靶向药物的应用不仅改善了患者生活质量，同时提高了患者的生存时间。免疫检查点抑制剂的应用则革新了驱动基因突变阴性患者的治疗策略。TNM分期是包括肺癌在内的实体瘤应用最为广泛的分期系统，统一的分期方法不仅为国际间的学术交流提供了共同的学术语言，同时也为疾病的预后判断及后续治疗决策制定提供了重要的工具。随着对肺癌预后因素的深入认识及研究数据的不断积累和成熟，肺癌TNM分期不断更新。2023年9月在新加坡举行的世界肺癌大会上，第9版TNM分期向全球公布并预计在2024年1月正式采用。本文就肺癌TNM分期的历史沿革、数据来源、第9版分期的主要变化及局限性进行讨论。 Lung cancer is the second commonly diagnosed cancer and remained the leading cause of cancer-related death, with an estimated 1.8 million deaths in 2020. The identification of driver gene mutation and administration of corresponding tyrosine kinase inhibitor have improved overall survival and quality of life in advanced lung cancer patients. Check point inhibitor has revolutionized treatment strategy of driver gene negative advanced NSCLC patients. TNM staging system is the most widely used classification method, providing an international common language during academic communication and important tool for predicting prognosis and subsequent treatment decision making. Accumulating knowledge about prognostic factors in lung cancer promotes the update of TNM classification. In the World Conference on Lung Cancer (WCLC) held in Singapore, September, 2023, International Association for Study of Lung Cancer (IASLC) released the forthcoming 9th edition of TNM classification for lung cancer, which is supposed to be adopted at January, 2024. The manuscript discussed the history, data resource and limitation of the TNM staging system.
