OBJECTIVE: The purpose of the study was to assess the effect of neutrophil-to-lymphocyte ratio (NLR) on recurrence and survival in patients with Esophageal Squamous Cell Carcinoma (ESCC) undergoing surgery. METHODS: This was a retrospective analysis of the 80 resectable ESCC patients who underwent surgery at Yuzuncu Yil University Faculty of Medicine between 2008 and 2018. Receiver operator characteristics curve of NLR was plotted for disease- free survival (DFS). The area under the curve of NLR was 0.692 (p=0.008) with 65.2% sensitivity and 2.8 with 69.5% specificity. Patients were divided into two groups based on the NLR as follows: NLR <2.8 and NLR ≥2.8. RESULTS: Among 80 ESCC patients, 54 (65.5%) were female. The median age was 55 years (range, 26–77). The NLR was <2.8 in 47 (58.7%) patients. Median DFS was 55 months in patients with NLR ≥2.8, whereas it was not reached in those with NLR <2.8 (p=0.008), with corresponding overall survival (OS) durations of 71 months and not reached (p=0.027). Eastern Cooperative Oncology Group performance score 2, presence of obstruction at diagnosis, lower 1/3 esophageal localization, neoadjuvant treatment, and NLR ≥2.8 were found to be the factors related to survival. CONCLUSION: The present study demonstrated that high pre-treatment NLR was associated with worse DFS and OS in patients with resectable esophageal cancer. We believe that pre-treatment NLR may help guide predicting treatment outcomes in non-metastatic resectable ESCC patients.
