Abstract

Background

An elevation in the neutrophil-to-lymphocyte ratio (NLR) has been shown to be associated with a poorer prognosis in patients with various tumors. The aim of this retrospective study was to clarify the correlation of the pretherapeutic NLR with the prognostic value of the pathologic response to neoadjuvant chemotherapy (NAC) in patients with advanced esophageal cancer.

Methods

This study was a retrospective review of 83 patients undergoing NAC for advanced esophageal cancer following esophagectomy. The NLR was measured before NAC, and the pathologic responses to NAC were evaluated.

Results

A comparison was performed for those whose pathology responded (responders) (G3/G2/G1b) and nonresponders (G1a/G0). In a univariate analysis, the cStage (P = 0.005), cN (P = 0.0001), and NLR (P = 0.005) were statistically significant parameters. A multivariate analysis revealed that the factors independently associated with pathologic responses were the pretreatment NLR (<2.2/≥2.2) (P = 0.043) and lymph nodes metastasis (P = 0.002). The pretreatment NLR (<2.2/≥2.2) was found to be a statistically significant useful predictive marker for a pathologic response (P = 0.001). The pathologic response rates were 56% in the patients with an NLR <2.2 and 21% in patients with an NLR of ≥2.2.

Conclusions

Our study is the first to demonstrate that the pretherapeutic NLR can be used as a predictor for chemosensitivity of thoracic esophageal cancer. Preoperative evaluation based on the clinical N stage and NLR may be easily used in routine clinical practice.
