Background. A new TNM staging system was proposed, and the previous system was revised in 1997. Methods. To evaluate the new TNM staging system for lung cancer, records of 3,043 lung cancer patients who underwent pulmonary resection at the National Cancer Center Hospital, Tokyo, were analyzed. Results. With regard to clinical stages, 3 patients had occult carcinoma; 786 patients had stage IA disease; 759 patients, stage IB; 54 patients, stage IIA; 469 patients, stage IIB; 582 patients, stage IIIA; 211 patients, stage IIIB; and 179 patients, stage IV. The 5-year survival rates for the respective stages were 70.8% for stage IA, 44.0% for stage IB, 41.1% for stage IIA, 36.9% for stage IIB, 22.7% for stage IIIA, 20.1% for stage IIIB, and 21.6% for stage IV. In terms of postoperative stages, 7 patients were classified in stage 0, 610 in stage IA, 506 in stage IB, 114 in stage IIA, 432 in stage IIB, 702 in stage IIIA, 448 in stage IIIB, and 224 in stage IV. The 5-year survival rates were as follows: stage IA, 79.0%; stage IB, 59.7%; stage IIA, 56.9%; stage IIB, 45.0%; stage IIIA, 23.6%; stage IIIB, 16.5%; and stage IV, 5.1%. Conclusions. In the clinical stage, there were significant prognostic differences between stage IA and stage IB, stage IIB and IIIA, and stage IIIA and stage IIIB, but there was no significant difference in 5-year survival rates between stage IB and stage IIA, stage IIA, and IIB, and stage IIIB and stage IV. In the postoperative stage, there were significant differences in 5-year survival rates between each stage except for stage IB and stage IIA.
