Evaluation of platelet distribution width as a diagnostic and prognostic biomarker in bladder neoplasm

Aim: To evaluate the role of preoperative platelet distribution width (PDW) as a potential biomarker for distinguishing malignancy and tumor advantage of bladder neoplasm. Methods: The study included 210 subjects with bladder cancer, 76 subjects with urothelial papilloma and 132 healthy control subjects. Preoperative PDW along with other blood indices was evaluated. Results: PDW was higher in urothelial papilloma patients than that in bladder cancer patients (p < 0.001). Bladder cancer patients with advanced-stage disease exhibited lower PDW levels compared with patients with early stage disease. Conclusion: Reduced preoperative PDW level is an indicator of malignancy and advanced bladder cancer stages, suggesting it as a potential biomarker in bladder cancer diagnosis and prognosis.
