目的了解遗传相关性大肠癌的临床特点。方法对120例大肠癌进行家系调查,对其中14例具有遗传相关性大肠癌的家系临床资料进行分析。结果具有遗传相关性大肠癌占同期大肠癌的11.67%,大肠癌一家族中有一级亲属两人以上发病的6个家族,占总的发病家族的1/20,而6个发病家族的发病人数为14人。占6个大肠癌家族一级亲属总人数(84人)的1/6。结论具有遗传背景的大肠癌家族成员是不可忽视的易感人群,临床上应提高对大肠癌病人家族调
Objective To understand the clinical features of genetically related colorectal cancer. Methods A total of 120 cases of colorectal cancer were investigated. The clinical data of 14 pedigrees with genetically related colorectal cancer were analyzed. The results of a genetic correlation of colorectal cancer accounted for 11.67% of the same period, colorectal cancer in a family of more than two relatives of six families, the incidence of the family of 1/20, and the incidence of the incidence of the six families For 14 people. Accounting for 6 colon cancer family first-degree relatives of the total number (84) of 1/6. Conclusion Family members of colorectal cancer with genetic background can not be ignored in susceptible population. Clinically, it is necessary to improve the family members of patients with colorectal cancer
