鉴于美国近几年前列腺癌的发病率仅次于皮肤癌而居第二位,由美国外科学院牵头,对2000所医院1984年和1990年前列腺癌的检查、治疗手段进行系统评价研究,其中1984年14710例新诊断前列腺癌资料来自730所医院,1990年的23214例前列腺癌资料来自10354所医院。病人平均年龄72.3岁,白人和非西班牙人占大多数(约86％)。 在诊断方式上,最常用的经肛门检查比例变化不大,1984年占53.7％,1990年占54.3％。但经尿道切除前列腺的比例从1984年的58.4％降至1990年的42.8％;经腹

In 1990, 23,214 cases of prostate cancer data came from 10,354 hospitals. The average age of the patients was 72.3 years, with whites and non-Spanishers accounting for the majority (about 86%). In terms of diagnosis, the rate of most commonly used transanal examinations did not change much, accounting for 53.7% in 1984 and 54.3% in 1990. However, the proportion of transurethral resection of the prostate decreased from 58.4% in 1984 to 42.8% in 1990;
