Platelet-to-lymphocyte ratio is not a predictor of clinically significant prostate cancer at the prostate biopsy: A large cohort study

Previous studies have reported conflicting results on the predictive role of the platelet-to-lymphocyte ratio (PLR) in detecting clinically significant prostate cancer (CSPCa) at the time of prostate biopsies. We explored the predictive value of pre-biopsy PLRs for CSPCa using our large-cohort database. Consecutive men with serum prostate-specific antigen (PSA) levels of ≥ 3.0 ng/mL or abnormal digital rectal examination (DRE) findings and who underwent prostate biopsies were included in the study. There was no significant difference in the pre-biopsy PLR between men with benign disease, clinically insignificant prostate cancer (CISPCa), and CSPCa. Only the subset of CSPCa patients with serum PSA levels of
