• To evaluate the efficacy of a clinic-based lung cancer screening program in the Takatsuki and Shimamoto (T/S) area, we retrospectively analyzed the outcome of 396 lung cancer patients treated in our department. The lung cancer patients were divided into four groups according to their residential area, i.e., T/S area or other areas (Oth) and the time of their consultation, i.e., before 1990 (early) or after 1991 (late): early T/S, late T/S, early Oth, and late Oth. Median survival times (MST) and 5-year-survival rates (5-YSR) were compared between these groups excluding patients detected by screening programs. MST (weeks) were 47.4, 74.9, 45.7 and 40.9 and 5-YSR (%) were 11.6, 23.5, 16.5 and 9.1 in the four groups, respectively. The outcome in the late T/S group was significantly better than that in any of the other groups (p=0.0184, 0.0267, 0.0363). The MST of MA+MB stage and N stage in the late T/S group (78.4 weeks and 39.7weeks, ) were the best among these 4 groups, but not significantly different.<BR>The results show that after 1991, in the T/S area, lung cancer was detected earlier in patients than in patients in the other areas. We believe it was the unique screening program in the T/S area that made it possible to detect lung cancer at an earlier stage through improving the general management quality of the general practitioners participating in the program.<BR>To evaluate the efficacy of a clinic-based lung cancer screening program, not only the direct benefit to individuals should be considered, but also the benefit returned to an area should be taken into consideration.
