| Objective To evaluate the new gastric cancer screening score (Li’s score). ,Japanese scoring methods and ABC method for screening early gastric cancer in early gastric cancer and precancerous lesions. Methods A total of 147 inpatients and outpatients in the Second People's Hospital of Hefei City from June 2018 to December 2021 were collected.After recording the basic information, all volunteers were scored using the Li’s scoring method,Japanese scoring method and ABC method.The subjects’ work characteristics (ROC curve) were drawn according to the patient’s endoscopic pathological examination to indicate early gastric cancer, to determine the best cut-off point for the diagnosis of early gastric cancer by the Li’s scoring method,Japanese scoring method and ABC method, respectively. The sensitivity and specificity of both scoring methods were calculated as well. Results Among the 147 patients included, 5 (3.4%) had gastric cancer and 65 (44.22%) had atrophy with or without precancerous lesions.The area under the ROC curve of Li’s scoring method,Japanese scoring method and ABC method, in the diagnosis of early gastric cancer, was0.686、0.736and 0.594, respectively. The best cut-off point of Japanese scoring method was 5.5, that is, Japanese score ≥6 was considered as the criteria for early gastric cancer screening, and the sensitivity and specificity were 94.3% and 31.2%, respectively.The best cut-off point of Li’s scoring method was 9.5, that is,Li’s score ≥10 was considered as the screening standard for early gastric cancer, and the sensitivity and specificity were 71.4% and 63.6%, respectively.The best cut-off point of ABC method was between B and C, that is, ABC method ≥C was considered as the screening standard for early gastric cancer, and the sensitivity and specificity were 60.0% and 58.4%, respectively.The area under the ROC curve in Li’s scoring is more significant than that in Japanese scoring and ABC method. Conclusions The Li’s scoring method has better specificity than the Japanese scoring method and ABC method, and the Japanese scoring method has better sensitivity than the Li’s scoring method and ABC method. |
