- Abstract: Objective To explore the value and affecting factors of miniprobe endoscopic ultrasonography (EUS) in the staging of early gastric cancer. Methods A total of 100 patients with pathologically-proved early gastric cancer who were admitted to Yan’an University Affiliated Hospital between February 2016 and February 2018 were enrolled in the study. All patients were examined by EUS before operation to determine the exact staging of gastric cancer, and the obtained results were compared with pathological results for evaluating the accuracy rate of EUS. According to the results of EUS examination, the patients were divided into accurate group and inaccurate group. The clinical features of two groups were compared, and the clinical features includes gender, age, body mass index, tumor diameter, differentiation type, tumor location, depth of invasion, gross classification and lymphatic vessel invasion. Logistic regression model was used to analyze the factors affecting EUS assessment of the staging of early gastric cancer. Results The accuracy rate of EUS in the staging of early gastric cancer at T1a, T1b and T2 stages was 88.57%, 82.61% and 78.95%, respectively, and the total accuracy rate was 84.00%. In accurate group, the percentages of tumors with a diameter ≥2 cm, tumors locating at the upper gastric segment and protruded type were 59.52%, 17.86% and 11.90%, respectively, which were lower than 87.50%, 50.00% and 43.75% in inaccurate group (P<0.05). The results of Logistic regression analysis indicated that tumor diameter (≥ 2 cm), tumor location (upper gastric segment) and gross classification (protruded type) were the risk factors for EUS in the staging of early gastric cancer (P<0.05). Conclusion EUS in the staging of early gastric cancer has a high accuracy rate, but the accuracy is affected by the diameter, location and gross classification of the tumor.
