REGRESSION, TUMOR, METASTASIS
The univariate Cox regression performed in the training group indicated that age, gender, grade, T stage, N stage, metastasis, primary site, tumor size, RNE, and chemotherapy were significant prognostic parameters for GNEC patients (P < 0.05). The important variables identified by univariate Cox regression were then incorporated in multivariate Cox regression analysis, demonstrating that each of these components was an independent variable (Table
