Abstract

Abstract: This study investigated the value of endoscopic ultrasonography (EUS) in differential diagnosis of benign and malignant gastric diseases and preoperative TNM staging of gastric cancer. The case control study was used in this paper, 94 patients with gastric cancer (gastric cancer group) and 98 patients with benign gastric diseases (benign group) confirmed by pathological examination were selected. All patients underwent EUS examination. The sensitivity of EUS in the differential diagnosis of benign and malignant gastric tumors was 92.55% and the specificity was 92.86%, the AUC value was 0.927. EUS correctly diagnosed 23 cases of T1 stage, 21 cases of T2 stage, 11 cases of T3 stage, and 8 cases of T4 stage. The Spearman correlation between EUS-diagnosed T stage and postoperative pathology was 0.818, Kappa=0.616 (all P<0.05). EUS correctly diagnosed 35 cases of N0 stage, 21 cases of N1 stage and 6 cases of N2 stage. Spearman correlation between N stage and postoperative pathology by EUS was 0.584, Kappa=0.523 (all P<0.05). EUS correctly diagnosed 64 cases of M0 stage and 15 cases of M1 stage. Spearman correlation between M stage and postoperative pathology by EUS was 0.733, Kappa=0.731 (all P<0.05). EUS has high sensitivity and specificity in the differential diagnosis of benign and malignant gastric tumors. At the same time, as a preoperative TNM staging evaluation method, it has a high consistency with the pathology of surgical results, so it could be used clinically as a gastric cancer patient methods of diagnosis and pathological judgment.
