摘要
目的探讨大肠息肉癌变的相关危险因素。方法收集该院2003～2012年行结肠镜检查的患者资料,对经病理证实为大肠息肉患者的性别、年龄、息肉的单发或多发情况、部位、大小、病理类型与癌变的关系进行分析总结。结果 2003～2012年间行肠镜检查共75 084例,检出息肉14 806例,检出率为19.72%。左半和右半大肠息肉的检出率在不同年龄段人群中差异有统计学意义(P<0.05),但全结肠息肉的检出率随年龄的增加而增高;上皮内瘤变和癌变的发生率随患者的年龄增加而增高;左半结肠息肉癌变率明显高于右半结肠(P<0.0167);息肉癌变率随其直径的增大而增高(P<0.01);各类腺瘤性息肉的癌变率均高于增生性息肉,息肉的绒毛成分愈多癌变率越高(P<0.01)。结论患者年龄、息肉的部位、大小和组织学类型是预测癌变危险性的重要指标,对年龄大于45岁、直径大于或等于1cm,特别是左半腺瘤性息肉应尽早行内镜下治疗,以防止大肠癌的发生。
Objective Colorectal polyp is a precancerous lesion of colorectal cancer .Aim of the study was to explore the risk fac-tors of colorectal polyp malignant transformation .Methods The related information of 75 084 colonoscopies performed from 2003 to 2012 in Southwest Hospital in Chongqing were collected and the relationship between polyp malignant transformation and the pa-tient age ,sex ,polyp location ,size or histological types was analyzed .Results From 2003 to 2012 ,polyps were diagnosed in 14 806 cases of the total 75 084 patients with a 19 .72% detection rate .There were significant difference of the left-side and right-side pol-yp detection rate in different age groups ,and the frequency of polyps distributed in the whole colorectum increased with the increase of age .The rates of epithelial neoplasia and malignant transformation increased with age .At the same time ,malignant transforma-tion rate was significant higher in polyps located in left-side than that in right-side （P〈0 .0167） ,in adenoma than that in inflamma-tory hyperplastic polyp （P〈0 .01） .The larger diameter and the more villus ,the higher rate of malignant transformation .Conclusion Patient age ,polyp size ,location and histological type could be considered as the significant predictors of colorectal polyp malignant transformation .It may be useful to treat the polyp with endoscopy in patient with age more than 45 and adenoma whose diameter was not less than 1 cm ,located in left-side for prevention of colorectal cancer .
