摘　　要：目的探讨胃间质瘤的超声表现及其与肿瘤侵袭危险性的关系。方法回顾性分析经超声检查及手术病理证实的胃间质瘤患者90例,分析其超声特点并与病理结果相对照。结果根据NIH 2008版将患者分为低危组37例和高危组53例,发现肿瘤大小、内部回声是否均匀、肿瘤形态、边界、内部血流信号与肿瘤恶性潜能存在相关性(P<0.05),而肿瘤大小是胃间质瘤侵袭危险性的独立预测因素。根据肿瘤最大径判断胃间质瘤侵袭危险性的ROC曲线下面积为0.901 (P<0.01)。结论超声可以对胃间质瘤进行初步诊断及肿瘤侵袭危险度评估。Objective To investigate ultrasonography in the diagnosis for gastric stromal tumor and compared to the malignant rank of the tumors.Methods 90 gastric stromal tumor cases confirmed histopathologically were retrospectively studied.US features of the tumors were compared with the results of histopathology.Results According to NIH 2008,cases were divided into low-risk group and high-risk group,the size,heterogeneous hypoechoes,contour,border and blood flow were markedly correlated with the patholobiologic behavior of tumors(P<0.05),the size of the tumors independently predicted malignant rank of the tumors.The area under ROC for size of the tumors was 0.901(P<0.01).Conclusions US is a primary method to diagnosis gastric stromal tumor,and can evaluate the malignant rank of the tumors.
