NLR was evaluated by Receiver Operating Characteristic curves, showing a maximum area under the curve of 0.635 a. Kaplan-Meier survival curves of patients with low preoperative NLR (≤ 3.65) were compared with those with a high NLR (> 3.65). The median OS was significantly longer in patients with a low NLR (25.5 months) than those with a high NLR (8 months) b
