N2 - Background: Soft tissue sarcomas are a heterogenous group of neoplasms without well-validated biomarkers. Cancer-related inflammation is a known driver of tumor growth and progression. Recent studies have implicated a high circulating neutrophil-lymphocyte ratio as a surrogate marker for the inflammatory tumor microenvironment and a poor prognosticator in multiple solid tumors, including colorectal and pancreatic cancers. The impact of circulating neutrophil-lymphocyte ratio in soft tissue sarcomas has yet to be elucidated. Methods: We performed a retrospective analysis of patients undergoing curative resection for primary or recurrent extremity soft tissue sarcomas at academic centers within the US Sarcoma Collaborative. Neutrophil-lymphocyte ratio was calculated retrospectively in treatment-naïve patients using blood counts at or near diagnosis. Results: A high neutrophil-lymphocyte ratio (≥4.5) was associated with worse survival on univariable analysis in patients with extremity soft tissue sarcomas (hazard ratio 2.07; 95% confidence interval, 1.54–2.8; P < .001). On multivariable analysis, increasing age (hazard ratio 1.03; 95% confidence interval, 1.02–1.04; P < .001), American Joint Committee on Cancer T3 (hazard ratio 1.89; 95% confidence interval, 1.16–3.09; P = .011), American Joint Committee on Cancer T4 (hazard ratio 2.36; 95% confidence interval, 1.42–3.92; P = .001), high tumor grade (hazard ratio 4.56; 95% confidence interval, 2.2–9.45; P < .001), and radiotherapy (hazard ratio 0.58; 95% confidence interval, 0.41–0.82; P = .002) were independently predictive of overall survival, but a high neutrophil-lymphocyte ratio was not predictive of survival (hazard ratio 1.26; 95% confidence interval, 0.87–1.82; P = .22). Conclusion: Tumor inflammation as measured by high pretreatment neutrophil-lymphocyte ratio was not independently associated with overall survival in patients undergoing resection for extremity soft tissue sarcomas.
