During the past 15 years, 274 patients (pts) have been operated on for primary lung cancer at Kitasato University Hospital, 204 men and 70 women. The histological diagnosis was adenocarcinoma (Ad) in 135, squamous cell carcinoma (Sq) in 101, small cell carcinoma in 12, large cell carcinoma in 9, adenosquamous carcinoma in 7, adenocystic carcinoma in 2, and others in 8. Staging was stage I in 117, stage II in 22, stage IIIa in 82 Mb in 26 and stage IV in 24 pts. The 5-year survival rates were 41.5% in the group of 274 pts, 57% in stage I, 43.8% in stage II, 20.7% in stage III (a+b) and 36.4% in stage IV. There was no statistically significant difference in the 5-year survival rates between Ad (39.6%) and Sq (46.6%), but among the pts who were classified as stage III (a+b), those with Sq had significantly better 5-year survival rate than those with Ad (Sq : 35.5%; Ad : 10.6%, p< 0. 05). Pts who underwent lobectomy had a better 5-year survival rate than those who underwent pneumonectomy (lobectomy : 51.6%; pneumonectomy : 20.6%, p<0.001). Among the pts who had relatively curative resections, those with Sq had significantly better 5-year survival rates than those with Ad (Sq : 43.1%; Ad : 14.2%, p< 0.05). Age was not a significant prognostic factor, nor did it affect operative mortality.
