- W2374795145 abstract "Background: Gastrointestinal stromal tumors( GISTs) are mesenchymal tumors with potential malignancy in gastrointestinal tract. Some endoscopic ultrasonographic( EUS) features have been reported to be suggestive for GISTs and its invasive risk. Aims: To assess the value of EUS in diagnosis and prediction of invasive risk of gastric stromal tumors.Methods: A total of 148 cases of gastric stromal tumors preliminarily diagnosed by endoscopy and EUS between Jan. 2010 and Apr. 2014 at Nanjing Drum Tower Hospital were retrospectively recruited. Of them 103 were proved to be gastric stromal tumors by postoperative histopathology. The endoscopic,EUS and clinicopathological features were collected,and the risk of tumor invasiveness was estimated based on EUS and histopathological features,respectively. Results: Taken pathological diagnosis as gold standard,the diagnostic accuracy of EUS for gastric stromal tumors was 69. 6%,and most of the misdiagnosis cases were leiomyoma and schwannoma. The coincidence rate of EUS and histopathology in classifying tumor invasive risk was 77. 7%,with a κ value of 0. 678( P = 0. 000) in consistency-checking test. Conclusions: An acceptable diagnostic performance can be achieved by using EUS for diagnosis of gastric stromal tumors. Furthermore,EUS can be used as a tool for prediction of invasive risk of gastric stromal tumors,and providing the basis for treatment regimen selection." @default.
