Abstract:Objective: To analyze the relationship between endoscopic typing of early gastric cancer and infiltration depth and lymph node metastasis. Methods: 103 patients with early gastric cancer admitted to the hospital from March 2020 to March 2023 were selected as the research subjects. General clinical data of patients were collected and the relationship between endoscopic typing, infiltration depth and lymph node metastasis was analyzed. Results: Among the 103 patients, 63.11% were males and 36.89% were females. The mean age was (52.36±10.73) years old and the mean maximum tumor diameter was (2.15±0.89) cm. The tumor locations were 20.39% in the upper part, 50.49% in the middle part and 29.13% in the lower part. The differentiation degree of gastric cancer showed that there were 37.86% of high differentiation, 43.69% of middle differentiation and 18.45% of low differentiation. Lauren typing revealed that interstitial type accounted for 49.51% and adenocarcinoma type accounted for 50.49% respectively. In terms of TNM staging, IA stage and IB stage accounted for 69.90% and 30.10%. According to endoscopic typing, there were 15 cases (14.56%) of type I, 64 cases (62.14%) of type II and 24 cases (23.30%) of type III among the 103 patients. The differences in tumor infiltration depth among different endoscopic types were statistically significant (P<0.05). In pairwise comparisons between groups, the differences between Type I and both Type II and Type III were statistically significant (P=0.025 and 0.032, respectively), and the difference between Type II and Type III was also statistically significant (P=0.047). The differences in lymph node metastasis detection rates among different endoscopic types were statistically significant (P<0.05). In pairwise comparisons, the rate for Type I was lower than that for Type II and Type III (P=0.028 and 0.015, respectively), and the rate for Type II was lower than that for Type III (P=0.036). Conclusion: Endoscopic typing of early gastric cancer is closely related to infiltration depth and lymph node metastasis.
