Comparison of overall survival in all patients with G-NENs of different TNM stages. The subgroups of patients with stage I and II obtained better OS than those in stage III and IV, respectively (I vs III, P < 0.001; I vs IV, P < 0.001; II vs III, P = 0.036; II vs IV, P < 0.001), as well as that between stage III and IV (P < 0.001), while no notable differences were found between stage I and II (P = 0.692)
