In all the prefectures of Japan, with the exception of Shiga Prefecture, more than half of local governments have an organized prostate-specific antigen (PSA) screening system in place. However, in the Shiga Prefecture, only a single city performed PSA screening over the time period of this survey. The purpose of the present study was to determine the clinical, pathological, and therapeutic features of newly diagnosed prostate cancer in localities where a formally organized screening system was almost entirely absent.

主要通过机会性 PSA 筛查发现的新诊断前列腺癌的临床、病理和治疗特征：日本滋贺县的一项调查

在日本的所有县，除滋贺县外，超过一半的地方政府都建立了有组织的前列腺特异性抗原 (PSA) 筛查系统。然而，在滋贺县，只有一个城市在本次调查期间进行了 PSA 筛查。本研究的目的是确定在几乎完全没有正式组织的筛查系统的地区新诊断的前列腺癌的临床、病理和治疗特征。
