Background: Endoscopy is the main approach used for esophageal squamous cell carcinoma (ESCC) screening, especially in high-risk areas. However, little consensus has been achieved in recent ESCC screening programs, and endoscopists have selected patients only by age and family history.
Patients and methods: To generate a proper strategy for selecting an eligible population for endoscopic screening based on demographic factors, lifestyle, and eating habits, a total of 7,830 residents in an area with a high risk of ESCC were recruited for this study. All participants underwent endoscopic examinations that were conducted by experienced endoscopists. Risk factors for ESCC and other lesions were selected by univariate and multivariate logistic regressions. A nomogram for the prediction of ESCC and premalignant lesions was constructed, which included information on age, sex, occupation, labor intensity, income, and mining exposure. Receiver operating characteristic (ROC) curve analysis was performed to present the predictive accuracy of the nomograms.
Results: The area under the curve (95% CI) was 0.749 (0.711–0.788) for this nomogram. By applying this nomogram, we could exclude 60% (4704/7830) of patients before endoscopy screening and detect all ESCC cases as well as most esophageal lesions in the remaining population.
Conclusion: In conclusion, we provided a ready-to-use preclinical tool with the potential to select eligible people with high risk of ESCC for endoscopy screening.
