We read with great interest the recent publication by Deng et al. (1) published in the March 2018 issue of Journal of Thoracic Disease. The authors have performed a meta-analysis in order to examine the role of platelet to lymphocyte ratio (PLR) in the prognosis of esophageal cancer and also to evaluate the relationship with tumor pathological characteristics.
