Prognostic value of preoperative platelet-related parameters and plasma fibrinogen in patients with non-muscle invasive bladder cancer after transurethral resection of bladder tumor.

To investigate the prognostic value of preoperative mean platelet volume (MPV), MPV/lymphocyte ratio (MPVLR), MPV/platelet count ratio and plasma fibrinogen in patients with non-muscle invasive bladder cancer (NMIBC) after transurethral resection of bladder tumor (TURBT). A total of 371 patients who underwent TURBT were enrolled. The main end points were disease-free survival (DFS) and overall survival (OS). MPVLR, tumor size, tumor number and pathological grade were independent risk factors for postoperative DFS. Age and pathological grade were independent risk factors for postoperative OS. MPVLR is an independent risk factor for DFS in NMIBC patients and could be used as a parameter to predict postoperative tumor recurrence in patients after TURBT.
