Abstract: Objective To evaluate the predictive value of peripheral blood neutrophil/lymphocyte ratio(NLR) on the prognosis of the elderly patients with metastatic esophageal cancer who received immunotherapy. Methods The clinical data of 116 elderly patients with metastatic esophageal cancer before immunotherapy were retrospectively analyzed. The optimal critical value of NLR was determined by X-tile software, and single factor and multiple factor Cox regression model was used to analyze the influencing factors for prognosis. Kaplan-Meier method was used to plot survival curves for relevant risk factors. Results The optimal threshold value of NLR before treatment was 2.8, according to which the patients were divided into low NLR group and high NLR group. Cox regression showed that NLR and Eastern Cooperative Oncology Group(ECOG) score before treatment were the independent risk factors for the prognosis of the elderly patients with metastatic esophageal cancer after immunotherapy. NLR<2.8 before treatment was associated with longer progression free survival (PFS) (P<0.001) and longer overall survival (OS) (P<0.001). Conclusions The NLR level can predict the efficacy of immunotherapy in the elderly patients with metastatic esophageal cancer, and may be a simple, economical, and effective prognostic indicator.
