The prognostic role of tumor size in stage T1 gastric cancer

The purpose was to assess the contribution of tumor size to the prognosis of patients with gastric cancer. Patient data were sourced from the Surveillance, Epidemiology, and End Results program (SEER) database. Cox proportional risk regression was performed to determine the prognostic role of tumor size. Kaplan-Meier curves were conducted to calculate survival curves. Consistency index (c-index) and subject exercise curve (ROC) were utilized to assess the predictive ability of each factor on the prognosis of gastric cancer. Tumor size is preferable to other widely accepted prognostic clinical features in forecasting the survival of patients with gastric cancer. The discriminatory ability of tumor size at T1 stage is superior to many other clinical prognostic factors.
