The number of cases, low risk cases/high risk cases were shown, p-value indicated the significance of different immune-nutritional risk between the patients with different clinical characteristics. PNI: Prognostic nutritional index; CONUT: Controlled nutritional status; NPS: Naples prognostic score; cTNM: Clinical Tumor-Node-Metastasis.
