Abstract:Objective To analyze the factors affecting diagnosis and morbidity of upper gastrointestinal cancer.Methods Clinical data of 17 830 patients who were performed with upper gastrointestinal endoscopy between January 2020 and January 2022 was collected. Combined with questionnaire and pathological examination, the diagnosis and morbidity of upper gastrointestinal cancer was analyzed.Results There were 88, 33 and 119 cases of carcinoma of esophagus, cardia and stomach respectively. Among them, 57, 27 and 91 cases of early carcinoma of esophagus, cardia and stomach were found. They were divided into the observation group (240 cases) and control group (17 590 cases). Univariate analysis showed significant differences between the two groups in education, drinking, pickled food, atrophic gastritis, intraepithelial neoplasia, painless gastroscopy, standard gastroscopy, and anxiety. Multivariate unconditional Logistic regression analysis and propensity score matching showed that drinking, atrophic gastritis, pickled food, intraepithelial neoplasia and anxiety were risk factors influencing the diagnosis and morbidity of upper gastrointestinal cancer.Conclusion Drinking, atrophic gastritis, pickled food, intraepithelial neoplasia and anxiety are risk factors influencing the diagnosis and morbidity of upper gastrointestinal cancer. Adjust the diet and life style, enhance the awareness of early cancer screening, can control the risk factors influencing the diagnosis and morbidity of upper gastrointestinal cancer.
