支气管癌的TNM 分期1986年提出新的TNM 分期,与1974年的分期有许多不同之处(参见《国外医学》呼吸系统分册1990;10(3):153～154).临床分期支气管肺癌Ⅰ期,目前限于N_(?)期.累及肺门淋巴结(N_1)的患者为Ⅱ期.转移到同侧纵隔和隆凸下淋巴结的局部转移(N_2)为Ⅲ_a 期.广泛肺外肿瘤(T_4)或广泛纵隔淋巴结转移(N_3)为Ⅲ_b 期.远处转移(M_1)的为Ⅳ期.临床Ⅰ、Ⅱ和Ⅲ_a期,经组织学检查证实为非小细胞肺癌者可手术切除
The TNM staging of bronchial cancer proposed a new TNM staging in 1986. There are many differences with the staging of 1974 (see Foreign Medical Respiratory System Volume 1990; 10(3):153-154). Clinical staging of bronchogenic carcinoma I , currently limited to the N_(?) phase. Patients with hilar lymph node (N_1) are stage II. Local metastases to the ipsilateral mediastinum and sub-tumor lymph nodes (N_2) are stage III_a. Extensive extrapulmonary tumors (T_4) or Metastatic mediastinal lymph node metastasis (N_3) is stage III_b. Distant metastasis (M_1) is stage IV. Clinical stages I, II, and III_a are histopathologically confirmed as non-small cell lung cancer.
