Purpose: Since 2003, a basic health checkup has involved prostate cancer screening with prostate specific antigen (PSA) alone. We investigated the results between 2003 and 2005., Subjects and Methods: Among males aged over 50 years who underwent a basic health checkup, the subjects were those who desired prostate cancer screening. Cancer screening with PSA alone was performed; mass screening or individual screening in hospitals in the city. We employed PSA with respect to age stratification. On the primary screening, written informed consent regarding the analysis of the screening results was obtained., Results: In 2003, there were 15,303 males aged over 50 years in Tatebayashi City. In 2003, 2004, and 2005, 11.8%, 12.2%, and 12.7% of the males underwent PSA screening, respectively. The rate of elevated PSA levels between 2003 and 2005 was 20.6%. Furthermore, 208, 165, and 179 males required secondary screening, and 80.3%, 61.2%, and 55.3% of the males underwent secondary screening, respectively. Of the males who underwent secondary screening, prostate biopsy was performed in 123 (73.2%), 54 (53.5%), and 38 (38.4%). Prostate cancer was detected in 60, 28, and 16 males, respectively. These values corresponded to 3.4%, 1.5%, and 0.8% of the males who underwent primary screening. The incidence of prostate cancer was 1.85% during the 3 years, and 3.2% in males who underwent the initial health checkup. Of 101 males in whom the stage was evaluated, the clinical stage was evaluated as B in 86 (85.1%), C in 9 (8.9%), and D in 6 (5.9%). Of the 101 males, endocrine therapy was performed in 46 (45.5%), surgery in 31 (30.7%), external irradiation in 5 (5.0%), and followup without treatment in 6 (5.9%). In addition, 7 (6.3%) desired treatment in another hospital, and 6 (5.9%) refused treatment., Conclusion: Prostate cancer was detected in 1.85% of males who underwent primary screening between 2003 and 2005. Of 101 males in whom the stage was evaluated, the clinical stage was evaluated as B in 86 (85.1%), and the early treatment of prostate cancer was achieved. This may lead to a future decrease in the mortality rate.

To evaluate the usefulness of endocrine therapy for stage B and C prostate cancer, we carried out a retrospective study on overall survival rate, cause-specific survival, PSA recurrence-free rate, and their predictive factors in 118 patients with stage B prostate cancer, 61 with stage C prostate cancer who underwent endocrine therapy at our department between 1985 and 2001. The cause-specific survival rate and PSA recurrence-free rate of stage B patients who underwent endocrine therapy were well, and they will take a good clinical course. Thus, in this stage of prostate cancer, aged patients and patients with complications may be good candidates for endocrine therapy. The cause-specific survival rate and PSA recurrence-free rate in the stage C patients who underwent endocrine therapy were significantly low. In stage C patients, endocrine therapy should be combined early with other methods such as radiotherapy. In the stage B patients who underwent endocrine therapy, PSA and Gleason score appeared to be associated with the cause-specific survival rate and PSA recurrence-free rate.
