Exploration of Predictors to Identify and Screen High Risk Patients With Early Gastric Cancer Submucosal Invasion
Objective To analyze the clinical,pathological,and endoscopic features of differentiated early gastric cancer,and to study predictors to identify and screen high risk patients with early gastric cancer submucosal infiltration.Methods A total of 172 patients with differentiated early gastric cancer treated by surgical or endoscopic submucosal dissection in our hospital from January 2017 to December 2022 were included,which were divided into the mucosal layer group(144 patients)and submucosal layer group(28 patients)based on postoperative pathology.The clinical,pathological,and white-light endoscopy(WLE)and linked color imaging(LCI)features of the 2 groups were compared.The color difference between the lesion and the surrounding mucosa was evaluated by using the Commission International de L'Eclairage(CIE)L*a*b*system.Indicators with significant differences were included to multifactor logistic stepwise regression analysis(forward method)for the identification and screening of predictors.Results A history of alcohol consumption(P=0.037),a history of smoking(P=0.035),thickening of the gastric wall on enhanced CT(P=0.032),a lesion located in the upper 1/3(P＜0.001)or middle 1/3(P=0.009)part of the stomach,depressed macroscopic type(P＜0.001),marked margin elevation(P=0.003),presence of fold changes(P=0.006),color difference ≥12.3 under WLE(P=0.003)and≥18.2 under LCI(P=0.002)were associated with submucosal infiltration.Multivariate analysis showed that lesions located in the upper 2/3 portion of the stomach(OR=5.463,95％CI:2.562-11.648,P＜0.001),depressed macroscopic type(OR=5.992,95％CI:1.624-22.100,P=0.007),marked margin elevation(OR=4.338,95％CI:1.124-16.747,P=0.033),and color difference ≥18.2 under LCI(OR=4.675,95％CI:1.342-16.288,P=0.015)were independent risk factors for infiltration of submucosal layer of lesions.Conclusion Lesions with depressed macroscopic type,marked elevated margins,located in the upper 2/3 part of the stomach,and having a large color difference from the surrounding mucosa under LCI are high-risk lesions for submucosal infiltration and require more aggressive intervention.
