摘要
目的:探讨胃肠道间质瘤多层螺旋CT表现以及与肿瘤危险程度的相关性。方法:回顾性分析42例经手术病理证实的间质瘤多层螺旋CT表现并与肿瘤危险程度分级进行对照。结果:42例中胃部24例,小肠12例,结肠1例,胃肠外5例,4例见肝转移。高度危险17例,中度危险12例,低度危险12例,极低危险1例。肿瘤发病部位与肿瘤的危险程度间有统计学意义(P=0.018,<0.05)。肿块大小与肿瘤的危险程度间有统计学意义(P=0,<0.01)。肿块形态、边缘情况、密度及强化方式与肿瘤的危险程度间有统计学意义(P<0.01)。肿块生长方式及强化程度与肿瘤的危险程度间无统计学意义(P>0.05)。结论:胃肠道间质瘤多层螺旋CT表现有一定特点,肿瘤发病部位、大小、形态、边缘情况、密度、强化方式可用于判断肿瘤危险程度,对治疗方案和随访有指导意义。
Objective：To discuss the CT findings and its correlation with the risk rank of gastrointestinal stromal tumors（GIST）.Methods：The multislice CT findings of patients with surgically and pathologically proved GIST were retrospectively analyzed,and compare to the risk rank of tumor.Results：In 42 cases,24 were located in stomach,12 in small intestine,1 in rectum and 5 outside gastrointestine,hepatic metastasis were found in 4 patients.17 cases were high risk,12 mid-range,12 lower risk and 1 lowest risk.The difference between location and risk rank of GIST was statistically significant（P=0.018,P0.05）.The difference between size and the risk rank of tumor was statistically significant（P=0,P0.05）.The differences between morph,margin,density,enhanced modality and the risk rank of GIST were statistically significant（P0.05）.The differences between gowth modality,enhanced degree and the risk rank of tumor were not statistically significant（P0.05）.Conclusion：The MSCT findings of GIST have some features.The location,size,morph,margin,density and enhanced modality can be used to judge the risk rank of GIST,and to guide treatment and follow-up.
