GNRI values were significantly associated with age (p < 0.001), BMI (p < 0.001), RBC (p < 0.001), albumin (p < 0.001), CRP (p < 0.001), tumor size (p < 0.001), operative procedure (p = 0.043), depth of tumor (p < 0.001), pathological stage (p < 0.001), and intraoperative blood loss (p = 0.029). The gene discussed is CRP; the disease is neoplasm.
