在699例直肠指检触诊有可疑发现者,进行了经会阴的前列腺穿刺活检,根据触诊发现的情况把病人分为三组:251例触诊明显怀疑肿瘤者,有171例(占68.1％)得到前列腺癌组织学上的证实。119例前列腺上有可疑孤立的结节者,有50例(占42％)是前列腺癌,但是在267例前列腺坚实度增加者,仅有62例(占18.8％)患有前列腺癌。直肠前列腺触诊,十年来是诊断前列腺癌,指导方向的检查方法,自从采用前列腺活检和根治性手术方法后,已清楚地表现出这种检查方法不可信赖,因为各种不同的前列腺疾病 In 699 patients with suspected rectal examination who were found to have palpable findings, a percutaneous prostate biopsy was performed. The patients were divided into three groups according to the findings of palpation: 251 cases with palpable suspected tumors, 171 cases (accounting for 68.1) %) Histological confirmation of prostate cancer. Of 119 suspiciously isolated nodules on the prostate, 50 (42%) were prostate cancers, but in 267 patients with increased prostate firmness, only 62 (18.8%) had prostate cancer. The rectal prostate has been palpated for the first time in the past decade as a diagnostic test for prostate cancer. Since the use of prostate biopsy and radical surgery, it has clearly shown that this test method is unreliable because of various prostate diseases.
