CRP and neoplasm: There was a significant association between the GNRI and various clinicopathological factors, such as the BMI (p < 0.0001), tumor size (p < 0.0077), depth of tumor (p < 0.0001), the pathological tumor-node-metastasis (pTNM) stage (p = 0.0038), serum squamous cell carcinoma (SCC) antigen (p = 0.0001), serum albumin levels (p < 0.0001), and C-reactive protein (CRP) levels (p < 0.0001).
