摘要
为探讨中国青年大肠癌的发病特点及地区分布特点，分析南方医院２０年间病理确诊的１１３５例大肠癌病例和近十年来国内发表的有关资料。结果示青年大肠癌发病率３．５％～２２．７％不等，对近二十年来不同时期大肠癌发病情况调查表明，青年大肠癌占同期大肠癌的比例已明显下降。青年大肠癌以直肠为多（４８％～６３％），右半结肠癌较之同期大肠癌为多。病程多在三个月内，临床症状无特征性，误诊率高达７７．８％～８５．７％。青年大肠癌分化程度较低，分化良好者３２％～６４％，五年生存率为２５．８％～４０．３％之间。本文结果有助于对我国青年大肠癌的发病特点及地理分布的了解，和指导临床防治。
To investigate the incidence and geographical features of colorectal cancer in patients under 30 years of age in China, 1 135 cases of large bowel cancer in Nanfang hospital identified from 1975 to 1995 and information published in chinese jurnals about young cancer were analysed.The results showed that incidence in patients under 30 years of age was decreased in recent decade,which was 3 5% 22 7%,Diet custom change and elder patients increase may be responsible for the lower incidence of young patients in some big cities of China. Rectum was mainly involoved(48% 63%),though righ colon lesions were found more than in the elder cases.Most patients were identified during three months with atypical clinic phenomena such as change of bowel habit,irregular abdominal pain,bloody stool or mucobloody stool.Abdominal mass was seldomly found and mis diagnosis rate was 77 8% 85 7%.Compared with elder patients,prognosis in young cases was by patients bad with only 32% 64% well differeciated and 25 5%～40 3% five year survival.These information is very helpful for understanding the incidence and geographical features of colorectal cancer in patients under 30 years of age in China.
