摘      要：BACKGROUND The features of gastric cancer based on the anatomic site remain unknown in northern China patients.AIM To analyze gastric cancer features and associated trends based on the anatomical site in northern China patients.METHODS This cross-sectional study used incident gastric cancer case data from 10 Peking University-affiliated hospitals(2014 to 2018).The clinical and prevailing local features were analyzed.RESULTS A total of 10709 patients were enrolled,including antral(42.97%),cardia(34.30%),and stomach body(18.41%)gastric cancer cases.Cancer in the cardia had the highest male:female ratio,proportion of elderly patients,and patients with complications,including hypertension,diabetes,cerebrovascular,and coronary diseases(P0.001).gastric cancer involving the antrum showed the lowest proportion of patients from rural areas and accounted for the highest hospitalization rate and cost(each P0.001).The proportion of patients with cancer involving the cardia increased with an increase in the number of gastroesophageal reflux disease cases during the same period(P0.001).Multivariate analysis revealed that tumor location in the cardia increased the risk of inhospital mortality(P=0.046).Anatomical subsite was not linked to postoperative complications.CONCLUSION The features of gastric cancer based on the anatomical site differ between northern China and other regions,both globally and within the country.Social factors may account for these differences and should affect policy-making and clinical practice.
