目的探讨螺旋CT对胃间质瘤(gastric stromal tumor,GST)的诊断价值。方法回顾性分析GST43例,所有病例均行螺旋CT平扫及三期增强扫描。所有病例均经病理免疫组化证实。统计分析采用SPSS 10.0统计软件包进行统计学处理,以浕=0.05为检验水准。结果43例GST中,良性9例(交界性5例),恶性34例,交界性GST被列在良性病例范围内。GST的大小、形态和均匀与不均匀的强化方式同良恶性相关(P<0.05)。GST的生长方式,有无坏死同良恶性不相关(P>0.05)。但是,17例既向腔内生长又向腔外生长的GST患者中,16例病理证实为恶性,有5例在3年内出现复发;5例GST呈间隔状强化,病理结果均为恶性,2例在3年内复发。结论螺旋CT对鉴别肿瘤良恶性、临床早期诊断和治疗以及评价预后具有重要价值。
Objective To investigate the diagnostic value of spiral CT in gastric stromal tumor (GST). Methods Retrospective analysis of GST43 cases, all cases were performed spiral CT plain and three enhanced scan. All cases were confirmed by pathological immunohistochemistry. Statistical analysis using SPSS 10.0 statistical package for statistical analysis, 浕 = 0.05 for the test level. Results Of the 43 GST cases, 9 were benign (5 borderline cases) and 34 were malignant. The borderline GST was included in the range of benign cases. The size, shape and homogeneity of GST were associated with benign and malignant lesions (P <0.05). GST growth, with or without necrosis with benign and unrelated (P> 0.05). However, of the 17 GST patients who developed both intraluminally and extracavitally, 16 were confirmed to be malignant and 5 were relapsed within 3 years. Five GSTs showed an interval-like enhancement and the pathological findings were all malignant. 2 Cases of recurrent within 3 years. Conclusion Spiral CT has important value in distinguishing benign and malignant tumors, early clinical diagnosis and treatment, and evaluation of prognosis.
