Evaluation of neutrophil-to-lymphocyte ratio prior to prostate biopsy to predict biopsy histology: Results of 1836 patients,” by Gocke et al.1 Investigators aimed to evaluate the role of neutrophil-to-lymphocyte ratio (NLR) prior to prostate biopsy to predict biopsy histology and Gleason score in patients with prostate cancer. The mean NLR of the prostate cancer group was significantly higher than that of the benign prostatic hypertrophy (BPH) group (p=0.002). The mean NLR of the prostatitis group was higher than that of both the prostate cancer and BPH groups (p=0.0001). The mean NLR of the Gleason score (GS) 8–10 group was higher than that of the GS 7 and GS 5–6 groups. The authors conclude that NLR was found to vary with regard to histology of prostate biopsy and higher GS was associated with higher NLR in patients with prostate cancer.
