摘要
目的:研究探讨胃肠道良恶性间质瘤的CT征象,并以临床病理结果为对照分析CT诊断的应用价值。方法:选取经手术病理或者免疫组化诊断并证实的胃肠道间质瘤患者32例作为研究对象,按照肿瘤的性质不同将其分为良性和恶性,回顾性分析患者的临床基本资料及CT诊断的影像学图像,比较胃肠道良恶性间质瘤的CT征象,并将CT诊断的结果与临床病理诊断结果进行对照,计算CT诊断的符合率。结果:32例胃肠道间质瘤患者,经病理诊断可以观察到梭形细胞、上皮细胞等两种主要形态,且均为单发病灶,包括良性肿瘤22例、恶性肿瘤10例。经CT扫描后确诊为胃肠间质瘤的有29例,诊断符合率为90.6%。恶性肿瘤的CT征象上直径>5cm、发生位置在肠道、病灶边缘模糊或分叶、密度不均匀、累及周围组织结构、合并淋巴结或脏器转移的比例显著高于良性肿瘤,比较均有统计学差异(P<0.05)。结论:胃肠道良恶性间质瘤的CT征象上存在比较明显的区别,通过多层螺旋CT扫描,可以对不同肿瘤病灶进行清晰直观的观察,并对其性质进行有效鉴别,与临床病理诊断结果相比,符合率高,值得临床推广应用。
Objective：To study the CT features of benign and malignant gastrointestinal stromal tumors, and to analyze the clinical value of CT diagnosis.Methods： 32 cases of patients with gastrointestinal stromal tumors confirmed by surgical pathology or immunohistochemical diagnosis were selected as research object and divided into benign and malignant according to the nature of tumors.The clinical data and the radiographic images of CT diagnosis of patients were retrospectively analyzed, and the benign and malignant gastrointestinal stromal tumor CT signs were compared.Then the CT findings and clinical pathology diagnosis results were contrasted, and calculated the coincidence rate of CT diagnosis.Results：32 cases of gastrointestinal stromal tumor patients diagnosed by pathological diagnosis can be observed two main forms including spindle cells and epithelial cells, and they were single lesions,including 10 cases of benign tumors and 22 cases of ma- lignant tumor.There were 29 cases of patients diagnosed with gastrointestinal stromal tumors by CT scanning,and the diagnosis coincidence rate was 90.6%.The ratio of diameter 〉5cm in CT signs,position in the intestinal tract, blurred edges or divided leaves, uneven density, involving around organizational structure, and lymph nodes or organ metastasis of malignant tumors were significantly higher than those of benign tumors, which the differences were statistically significant （P 〈0.05）.Conclusion：There are obvious differences on the CT signs of benign and malignant gastrointestinal stromal tumors.Different tumor lesions can be clearly and intuitionally observed by multi-slice ct scanning,and the nature of tumors can be effectively identified.Com- pared with the results of clinical pathological diagnosis,the coincidence rate of CT signs is high,which is worthy of clinical promotion and application.
