非小细胞肺癌分期技术的应用研究及第七版肺癌分期的解析

Non-small cell lung cancer staging system and the implication of 7th lung cancer TNM classification

肺癌最常用的肿瘤分期系统是TNM分期，国际肺癌研究协会（IASLC）在第13界世界肺癌大会上公布了新修订的第七版肺癌TNM分期。准确的临床分期有赖于从病史、临床检查、影像学检查及侵入性检查等多方面分析，准确的临床分期对于指导治疗具有重要意义，第七版肺癌TNM分期分别从原发病灶、淋巴结转移及远隔脏器转移方面分别作了修订，使之更准确地对应患者预后。

The TNM staging is the most common tumor staging system of lung cancer. The new revisioned 7th lung cancer TNM staging is published by the international association for the study of lung cancer （IASLC） in the 13th world conference on lung cancer. Accurate clinical staging depends on the multi-analysis from medical histroy, clinical examination, imaging examination and invasive test, which has important significance for guiding the treatment of lung cancer. The 7th lung cancer TNM classification has been revised respectively from the primary focus, lymph node metastasis and remote viscera metastasis, so as to make it more accurately corresponding to the prognosis of patients.
