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

ABSTRACT

Aim: 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). Methods: A total of 371 patients who underwent TURBT were enrolled. The main end points were disease-free survival (DFS) and overall survival (OS). Results: 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. Conclusion: 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.

The current study investigated the prognostic value of preoperative mean platelet volume (MPV), MPV/lymphocyte ratio (MPVLR), MPV/platelet count ratio (MPVPCR) and plasma fibrinogen (PF) in peripheral blood of patients with non-muscle invasive bladder cancer (NMIBC) after transurethral resection of bladder tumor (TURBT). Included were 371 patients who underwent TURBT and were followed up. A high level of PF indicated worse survival and age and pathological grade were independent risk factors for postoperative survival. High levels of MPV, MPVLR and MPVPCR were associated with recurrence. MPVLR, tumor size, tumor number and pathological grade were independent risk factors for postoperative recurrence. MPVLR could be used as a parameter to predict postoperative tumor recurrence in patients after TURBT.
