摘　　要：目的:分析胃肠道间质瘤(gastrointestinal stromal tumors,GIST)的临床特征、CT影像和病理特征。方法:择取该院于2016年7月~2020年7月诊治的66例胃肠道间质瘤患者作为本次研究对象,并以回顾性分析形式记录所有数据。66例患者均实施CT检查,将病理数据作为基础,记录患者的临床特征、良性以及恶性肿瘤CT影像表现差异。结果:66例患者中,8例为良性、17例为潜存性恶性、41例为恶性。CD117阳性表达率高达98.48%以上,CD34阳性表达率高达69.69%以上。46例患者CT中呈现为膨胀生长,呈现为球形/椭圆状密度肿块,CT形态呈现分叶状形态占20例。25例患者CT平扫肿块密度相对均匀占25例,38例患者病灶影像学上显示均有不同程度坏死、出血和囊变。43例肿块病灶边界与周围清楚,23例肿块病灶边界与其附近的相关脏器黏连。所有的研究病例病灶均未发现钙化。所有病例增强CT扫描结果显示:轻度强化的病例为9例,中等程度的强化病例为15例,不均匀强化病例42例。结论:通过对胃肠道间质瘤的临床特点及CT影像及病理分析,为临床初步判断肿瘤的危险程度,治疗方案及预后体现重要价值。Objective:To investigate the clinical,CT and pathological characteristics of gastrointestinal stromal tumors(GIST).Methods:66 patients with gastrointestinal stromal tumor diagnosed and treated in our hospital from July 2016 to July 2020 were selected as the subjects of this study,and all data were recorded in the form of retrospective analysis.All 66 patients were examined by CT,and pathological data were used as the basis to record clinical characteristics and differences in CT images of benign and malignant tumors.Results:Among 66 patients,8 cases were benign,17 cases were latent malignant and 41 cases were malignant.The positive expression rate of CD117 and CD34 was more than 98.48%and 69.69%respectively.The CT findings of 46 patients showed swelling growth,spherical/elliptical density mass,and lobulated shape in 20 cases.The mass density of 25 patients on CT plain scan was relatively uniform,accounting for 25 cases.The imaging findings of 38 patients showed necrosis,hemorrhage and cystic change in varying degrees.In 43 cases,the boundary of the mass was clear,and in 23 cases,the boundary of the mass was adhered to its adjacent organs.No calcification was found in all cases.The results of enhanced CT scan in all cases showed that 9 cases had mild enhancement,15 cases had moderate enhancement and 42 cases had uneven enhancement.Conclusion:Through the clinical characteristics,CT image and pathological analysis of gastrointestinal stromal tumor,it is of great value to preliminarily judge the risk degree,treatment plan and prognosis of the tumor.
