Prostate cancer detection by prostate-specific antigen-based screening in the Japanese Hiroshima area shows early stage low-grade and low rate of cancer-specific death compared with clinical detection

摘要

Introduction:We investigate the effectiveness of prostate-specific antigen (PSA) screening for prostate cancer. We compare the characteristics of 2 sets of patients: (1) those in whom prostate cancer was detected via PSA screening (the PS group) and (2) those in whom prostate cancer was detected at the outpatient office (the non-PS group).
