浙北地区大肠癌若干流行病学特点

目的：了解本地区大肠癌的流行病学特点。方法：回顾性分析我院近８年来从接受结肠镜检查的５３２０例就诊者中检出的３３９例大肠癌患者的临床资料及结肠镜所见。结果：大肠癌总检出率为６．３７％。历年检出率在４．６０－８．７９％之间。男性检出率略高于女性，男女之比１．１５：１。４０－６０岁为最好年龄段（４８．３７％）。直 肠和乙状结肠为最好发部位，二者所占比例达大肠癌总数的７１．３８％。病理组织学上以腺癌为主（８９．３８％）。结论：大肠癌的发生具有明显的好发年龄及好发部位，且多数为腺癌。本地区大肠癌检出率在过去的８年里无逐年上升或下降趋势。

STUDY ON THE EPIDEMIOLOGICAL CHARACTERISTICSOF LARGE INTESTINE CARCINOMA IN NORTH ZHEJIANG

Objective:The aim of this study was to explore the epidemiological characteristics of large intestine carcinoma in North Zhejiang.Methods:A retrospective review of clinical records and endoscopic findings of 339 large intestine carcinoma patients (detected from 5320 endoscopic examinees) throught past 8 years was executed.Results:General detection rate was 6.37%.Annual detection rate fluctuated between 4.60% and 8.79%.The detection rate for male was slightly higher than that for female.The ratio of male to female was 1.15∶1.The 41～60 years interval was the susceptible age interval (48.37%);rectum and sigmoid colon were the most frequently sites involved (71.38%).Most (89.38%) of the carcinomas were adenomatous histopathologically.Conclusions:There were susceptible age interval and topological sites for large intestine carcinoma.Most of them were adenomatous.Annual detection rate in this region through the past 8 years showed neither rise nor decline year by year.
