Surgery remains the primary treatment for patients with esophageal cancer (EC), but postoperative prognosis is often unsatisfactory. We developed an interactive web-based tool to estimate cancer-specific survival (CSS) in patients with T1~3N0~2M0 EC after surgery, based on the log odds of negative lymph nodes/T stage ratio (LONT). A total of 2,221 patients were selected from the Surveillance, Epidemiology, and End Results (SEER) database and randomly divided into training and testing sets. Univariate Cox regression analysis revealed that age, sex, T stage, N stage, chemotherapy, and LONT were significantly associated with CSS. ROC curve comparisons using Cox regression and random survival forest (RSF) models showed that LONT outperformed N stage in predictive accuracy, particularly for 1-year CSS. Decision curve analysis (DCA) and calibration curves indicated that the model had high predictive accuracy. Finally, we developed an interactive web-based tool of effectively estimating 1-, 3-, and 5-years CSS and survival trends in postoperative patients with T1~3N0~2M0 EC.
