Lan Z, Hu H, Mandip R, et al. - In this prospective cohort study, researchers assessed the precision of linear endoscopic ultrasound (EUS) for the diagnosis of submucosal (SM) invasion and compare linear EUS with radial EUS in suspected early gastric cancer (EGC) patients. The study sample consisted of 72 consecutive patients with suspected EGC who had a preoperative assessment using linear EUS or radial EUS. According to results, the sensitivity was 92.3% for linear EUS and 90.9% for radial EUS. The specificity in the linear EUS group was 90.0%, whereas in the radial EUS group the specificity was 60.7%. According to univariate analysis, EUS type was an associated risk factor of incorrect T1b staging in patients with EGC. For linear and radial EUS, respectively, the area under the receiver operating curve was 0.912 and 0.758. In suspected patients with EGC, Linear EUS was more precise to determine SM invasion and therapeutic approach compared with radial EUS.
