INTRODUCTION: Neoadjuvant treatment is currently the gold standard for advanced esophageal squamous cell carcinoma (ESCC). Several studies have examined the value of blood count-based indexes for predicting short- and long-term outcomes after esophagectomy for ESCC, but the relative predictive value of pretreatment, preoperative, and postoperative indexes has not yet been examined.
METHODS: This study included 320 patients with thoracic ESCC who underwent subtotal esophagectomy after neoadjuvant chemotherapy or chemoradiotherapy at our institution. A total of 19 candidate blood parameters were measured before neoadjuvant treatment as well as preoperatively and postoperatively. The ability of the parameters to predict postoperative complications, overall survival (OS), and relapse-free survival (RFS) was assessed using receiver operating characteristic (ROC) curve analysis and Cox regression analysis.
RESULTS: ROC curve analysis indicated that preoperative platelet to lymphocyte ratio (PLR) had the best predictive value with an optimal cutoff value of 166. Patients with high preoperative PLR (≥166) had significantly shorter OS and RFS and significantly higher incidences of hematogenous recurrence and postoperative pneumonia compared with patients with low preoperative PLR (<166). In multivariate analysis, high preoperative PLR and high preoperative serum carcinoembryonic antigen level were independent predictors of poor prognosis.
CONCLUSION: Preoperative PLR is a good predictor of short- and long-term prognosis in patients with advanced ESCC who receive neoadjuvant treatment followed by radical resection.
