title: Longer survival after resection of non-small cell lung cancer in Japanese women.
abstract: From 1974 to 1988, 492 patients (361 male and 131 female) with non-small cell lung cancer underwent pulmonary resection at our department. A retrospective study was done with special reference to the sex of the patients. There was no sex-related association with age distribution, operation, pathological T or N status, or staging. On the other hand, 77.9% of women had an adenocarcinoma and only 44.6% of men had this type of lesion. This was considered at least partly a result of sex difference in smoking habits. Women survived for a significantly longer time (p = 0.0036), and this difference could not be explained by differences in histological type. Presumably, hormonal factor(s) may contribute to the prognosis.
