An epidemiological survey of prostatic cancer from the Annual of the Pathological Autopsy Cases in Japan.

One thousand two hundred and ten cases of prostatic cancer from the Annual of the Pathological Autopsy Cases in Japan (1958--1975) were collected and subjected to statistical studies. The number of deaths caused by prostatic cancer increased yearly. The age distribution showed a peak in 70--74 years. Neither particular diseases nor cancers were observed to be associated with prostatic cancer. The incidence of liver cirrhosis was significantly lower in prostatic cancer cases than in all male autopsy cases in the Annual. The lymphnodes, the bones and the lungs were the most frequent metastatic regions for prostatic cancer. Histologically, 85% of the cases were adenocarcinoma.
