Abstract Objective To study the correlation between endoscopy, pathologic characteristics and tumor invasion in early gastric cancer (EGC) by a retrospective analysis. Methods Endoscopic and clinicopathological features in 72 patients by endoscopy, pathological and post-operative EGC diagnosis were analyzed. Results Gender, age, main symptoms, differentiation, and endoscopic morphology typing of patients was not correlated with depth of invasion (P>0.05). 15 cases with submucosal tumor invasion and the lesion size diameter≥2 cm accounted for 60.00% (χ2=22.273, P=0.000, Cramer’s V coefficient=0.556). Lesion site is associated with depth of invasion (χ2=17.743, P=0.000, Cramer’s V coefficient=0.496). The upper lesion invading the submucosa accounted for 77.78%, while the middle and lower lesion invading the submucosa, only in 12 cases, accounted for 19.05%. Conclusions Lesion site and lesion size in EGC are closely related to the depth of invasion. It will provide further guidance for EGC in detection, treatment and prognosis.
