ある一町村における前立腺集団検診 : 5年間の結果および検診システムについて

Abstract

1)平成1年より5年間にわたり川越町で前立腺検診を実施し, のべ216名中4名の前立腺癌を発見した。2)腫瘍マーカー(PSA), 直腸診, TRUSの順で, 診断精度が良かった。3)川越町民の前立腺検診に対する希望は対象住民1, 887名中147名(約8%)で, 一般検診希望の34%から大きく離れていた。4)受検率を上げるには, 前立腺疾患の啓蒙を積極的に行い, 関心を抱かせることと, 老健法の範囲に前立腺検診の項目が組み入れられることが必要である。5)私たちの前立腺集団検診のシステムとして一次に問診, 直腸診, PSA, 二次にTRUS+系統的生検を組み入れることが一番効率的である

The results of a mass screening examination for prostate cancer conducted from 1989 to 1993 at a local town, Kawagoe-cho, in Mie Prefecture were evaluated. Among the 216 examinees, 4 were found to have prostate cancer. The most accurate examination was the prostate specific antigen (PSA), which was followed by digital examination and transrectal ultrasound. The applicants for the prostate cancer screening accounted for only 8% of the Kawagoe-cho male residents over 40 years old. An educational campaign of prostate disease in the area must be started to increase the number of applicants. We concluded that the most effective modality for the screening program was a combination of PSA and digital examination in the field study, and transrectal ultrasound accompanied by systemic biopsy results in the second tool for screening.
