Does the derived neutrophil/lymphocyte ratio predict poor clinical outcome in soft tissue sarcoma patients? Context: Inflammation plays an important role in tumor proliferation and survival in cancer patients. The aim of this study was to investigate the prognostic impact of the pre-operative-derived neutrophil/lymphocyte ratio (dNLR) in a large cohort of soft tissue sarcoma (STS) patients after curative surgical resection. The impact of preoperative dNLR on disease-free survival (DFS) and overall survival (OS) in retrospectively evaluated 340 STS patients was assessed using Kaplan-Meier curves and Cox proportional models. Applying receiver operating curve analysis, we determined a cut-off value of 2.39 for the dNLR to be optimal for discrimination of patients' survival in the whole cohort. Kaplan-Meier curves revealed a dNLR greater than or equal to 2.39 as a marker for decreased DFS (P = .031) and OS (P = .007, log-rank test) in STS patients. In multivariate analysis, increased dNLR was significantly associated with poor OS (hazard ratio 1.60, 95% confidence interval 1.07 to 2.40, P = .022).

This study demonstrates that preoperative dNLR might represent a well-correlated surrogate marker for the widely validated NLR. The dNLR is easily obtainable and can provide important information for individual risk assessment in clinical trials. Final Decision: yes
