    Abstract:
    BACKGROUND AND OBJECTIVES: Accumulating evidence indicates an important pathophysiological role of fibrinogen on tumor cell progression and metastases in different types of cancer. The aim of the present study was to evaluate the prognostic relevance of pre-operative fibrinogen levels on clinical outcome in a large cohort of STS patients. METHODS: Two hundred ninety-four consecutive STS patients were retrospectively evaluated. Cancer-specific survival (CSS), disease-free survival (DFS), and overall survival (OS) were assessed using the Kaplan-Meier curves and Cox regression models. Finally, we supplemented the well-established Kattan nomogram by the fibrinogen level and evaluated the gain of predictive accuracy of this novel nomogram by Harrell's concordance index (c-index). RESULTS: An elevated plasma fibrinogen level was significantly associated with established prognostic factors, including age, tumor grade, size, and depth (P<0.05). Furthermore, in multivariate analysis, increased fibrinogen levels were significantly associated with a poor outcome for CSS (HR=2.48; 95% CI=1.28-4.78; P=0.007), DFS (HR=2.00; 95% CI=1.11-3.60; P=0.021), and OS (HR=2.20; 95% CI=1.39-3.47; P<0.001). The estimated c-index was 0.747 using the original Kattan nomogram and 0.779 when the fibrinogen levels was added. CONCLUSION: The pre-operative plasma fibrinogen level may represent a strong and independent unfavorable prognostic factor for CSS, DFS and OS in STS patients.
