Neutrophil/lymphocyte ratio predicts lymph node metastasis in patients with gastric cancer.

The sensitivity and specificity of PLR, tumor staging and tumor size are lower than NLR. Preoperative NLR can be used as an independent risk factor for the prediction of lymph node metastasis, and one of the effective indicators for predicting the prognosis of patients. Preoperative NLR may be an effective auxiliary tool to assess lymph nodes in GC patients.
