SII was significantly associated with age (p = 0.024), American Society of Anesthesiologists physical status (ASA-PS) classification (p < 0.001), BMI (p = 0.044), white blood cell count (WBC) (p < 0.001), lymphocyte count (p < 0.001), neutrophil count (p < 0.001), platelet count (p < 0.001), tumor size (p = 0.002), depth of tumor (p < 0.001), lymph node metastasis (p = 0.044), pTNM stage (p < 0.001), C-reactive protein (CRP) level (p < 0.001), NLR (p < 0.001), and PLR (p < 0.001) (Table 1). Here, CRP is linked to metastatic malignant neoplasm in the lymph nodes.
