To assess the ability of preoperative plasma fibrinogen and D-dimer as biomarkers to predict survival outcomes in patients with non-muscle-invasive bladder cancer (NMIBC). A total of 206 NMIBC patients receiving transurethral resection of bladder tumor (TURBT) were assessed in our retrospective study. The cutoff values of fibrinogen and D-dimer were determined using receiver operating characteristic curve analysis. Cox regression analyses were adopted to assess the influence of these two parameters on recurrence-free survival (RFS) and progression-free survival (PFS). The cutoff values of fibrinogen and D-dimer were 3.56 g/L and 0.48 μg/mL, respectively. Kaplan-Meier analysis demonstrated that high fibrinogen and D-dimer levels were significantly related to poor RFS (all P< .001) and PFS (all P< .001). Moreover, patients with elevated fibrinogen levels tended to have high tumor grade (P= .033), advanced pathologic T stage (P< .001), and multiple tumor lesions (P= .019). Significant associations of high D-dimer levels with advanced pathologic T stage (P= .026), large tumor size (P= .012), and multiple tumor lesions (P= .006) were found. In addition, multivariate analysis revealed that plasma fibrinogen and D-dimer were all independent predictive factors for RFS (P= .029 and .001, respectively) and PFS (P= .023 and .003, respectively). High levels of preoperative plasma fibrinogen and D-dimer may indicate advanced clinicopathologic features and worse prognosis, suggesting that these two coagulation parameters could be used as prognostic biomarkers for NMIBC patients.
