目的:探讨前列腺癌发病与输精管结扎的相关性。方法:收集宜昌市6家医疗机构1996~2005年间收治的3 186例60岁以上前列腺疾病(前列腺增生症,前列腺癌)住院患者,按是否接受输精管结扎分为结扎组(979例)与未结扎组(2 207例)进行回顾性研究,按年龄分层分析统计两组中经病理学检查确诊的前列腺癌患者的发病率并比较其差异。结果:结扎组(60~、65~、70~、75~岁年龄组)前列腺癌的发病率显著低于未结扎组。结论:前列腺癌的发病率与输精管结扎有关,输精管结扎可降低前列腺癌的发病率。
Objective: To investigate the correlation between the incidence of prostate cancer and vasectomy. Methods: A total of 3 186 hospitalized patients with prostate disease (benign prostatic hyperplasia and prostate cancer) over 60 years of age from 1996 to 2005 in Yichang City were enrolled and divided into ligation group (979 cases) and non-ligation group Group (2 207 cases) were retrospectively studied. The incidence of prostate cancer patients diagnosed by pathological examination in both groups was calculated by age stratified analysis and the differences were compared. Results: The incidence of prostate cancer in the ligation group (60 ~, 65 ~, 70 ~, 75 ~ age group) was significantly lower than that in the non-ligation group. Conclusion: The incidence of prostate cancer is related to vasectomy, and vasectomy can reduce the incidence of prostate cancer.
