Objective and Methods: Clinical features and outcome of lung cancer in women were analyzed based on the results of mass screening. A total of 341 cases of lung cancer, including 115 women and 226 mem, were detected in 1987 and 1998 in Tottori prefecture. Results: On comparison of backgrounds according to gender, there was a significantly lower prevalence of smoking history and greater frequency of adenocarcinoma patients in women. Lung cancer in women had a significantly better outcome, especially in advanced stage II, III and IV cases and in adenocarcinoma cases compared with men. Furthermore, multivariate analysis using Cox's proportional hazard model showed that gender was a significant prognostic factor along with clinical stage and surgical procedure. Conclusion: Lung cancer in women detected by mass screening had a better outcome than in men with a 1.61 hazard ratio.
