Summary

In our era of personalized treatment, both the prognosis and the choice of therapy for upper GI malignancies depend on the staging before any treatment. Most experts recommend EUS (Endoscopic Ultrasound) as the first line for T-staging but the diagnostic accuracy in clinical practice varies in different centers according to the published data. Neither the discrepancy between EUS and histological findings nor the variation between centers well explained. So the investigators designed this prospective study. In the present study, the investigators performed EUS on the resected specimen after surgery before fixation in formalin, evaluated the invasion of the GI wall, and marked the deepest location with sutures. And try to determine the exact accuracy of EUS staging , find the discrepancy between EUS and histologic findings.
