 note = {To evaluate the suitability and problems of the new TNM staging system for primary lung cancer, especially in stage IIIA, IIIB and IV, records of 731 cases (557 resected cases were included) of non-small cell lung cancer were re-analyzed. The 5-year survival rates after resection of each stage were as follows : stage 0 and I : 64.6%, stage II : 38.9%, stage IIIA : 20.7%, stage IIIB : 12.4%, stage IV : 7.5%. There were significant differences of survival rates between stage I and II, II and IIIA as well as IIIA and IIIB, respectively. However, there was no significant difference between IIIB and IV. In cases of curative resection, the 5-year survival rates after resection of each stage were as follows : stage 0 and I : 67.4%, stage II : 42.3%, stage IIIA : 27.3% and stage IIIB : 20.1%. There were significant differences of survival rates between stage I and II, II and IIIA, respectively. However, there was no significant difference between IIIA and IIIB. In stage IV, longer surveval cases were experienced in cases of ipsilateral intrapulmonary metastasis (PM), especially in cases of clinical PM0. It is concluded that the classification of stage IIIB and IV must be reconsidered in the next TNM staging. 非小細胞癌731例中, 切除557例を新TNM分類にて検討した。5年生存率は, 0期+I期 : 64.6%, II期 : 38.9%, IIIA期20.7%, IIIB期 : 12.4%, IV期 : 7.5%であった。IIIB期とIV期の生存率には有意差は認められなかったが, その他の各病期間では生存率に有意差を認めた。同側肺内転移切除例はIV期の中では予後良好であり, IIIB期切除例と同程度であった。, 金沢大学医薬保健研究域医学系},
