Abstract
BACKGROUND
Synovial sarcoma is a rare malignant soft tissue tumor, more common in adolescents and young adults and entails a poor prognosis. Several good prognostic factors have been well established such as age less than 25, size less than 5 cm and absence of a poorly differentiated component. Inflammation has a well-established role in tumor proliferation and survival. The aim of this study was to investigate the prognostic significance of the neutrophil/lymphocyte ratio (NLR) in a large cohort of synovial sarcoma patients.
METHODS
Retrospective study of 169 consecutive patients. We analyzed the relation of preoperative NLR on disease-free survival (DFS) and overall survival (OS) using Kaplan-Meier curves and Cox proportional models.
RESULTS
Of the 169 patients included, there were 90(53.3%) females and 79(46.7%) males. Median age was 32yo (11-73). Median survival was 34.1 and mean disease-free survival was 21.4 months. Mean tumor size was 12.5 cm (1.2-77 cm). Applying receiver operating curve analysis, we determined a cut-off value of 3.5. In univariate and multivariate analysis, increased NLR was significantly associated with poor OS. A <3.5 NLR was an independent prognostic factor in all stages (p = 0.002).
CONCLUSIONS
NLR >3.5 was found to be a reliable prognostic factor in this cohort. Given its widespread availability, we believe it's use in clinical practice and further clinical trials should be considered.
