Endosonographic surveillance of 1-3 cm gastric submucosal tumors originating from muscularis propria

Figure 1 Flow chart of management of 88 indicated patients with submucosal tumors originating from the muscularis propria in the stomach. EUS: Endoscopic ultrasound; GIST: Gastrointestinal stromal tumor.

Figure 2 Receiver operating characteristic curve analysis of tumor size for predicting potential tumor progression. Initial tumor size of 1.4 cm was determined as the optimal cut-off size, with a sensitivity of 68.0%, a specificity of 66.7%, and an accuracy of 67.0%.
