Neutrophil-to-lymphocyte and neutrophil-to-monocyte rates in the decision for a prostate re-biopsy in patients with a previous benign pathology and consistently 2,5-10 ng/ml PSA value

In this study we compared neutrophil-to-lymphocyte ratio (NLR) and neutrophilto- monocyte ratio(NMR) between patients with prostate cancer after first transrectal ultrasound (TRUS)- guided biopsy and patients with benign prostate hyperplasia(BPH) after second TRUS-guided biyopsy.

A total of 224 patients who underwent multi (≥12)-core TRUS -guided biopsy at our clinic for elevated PSA or abnormal digital rectal examination in between January 2008 and March 2015 were retrospectively analyzed. There were 2 groups. Group 1 consisted of 146 patients with a diagnosis of prostate cancer after the first TRUSguided biyopsy and group 2 consisted of 78 patients with a diagnosis of benign prostate hyperplasia after second TRUS-guided biyopsy. Age, PSA, NLR and NMR values were compared between the two groups.

There were no statistically significant correlation between PSA and NLR(p=0.46). The mean of age, PSA, NLR, NMR values in the group 1 and 2 were respectively 64.6±7.7 and 61.6±6.9, 6.5±1.9 and 5.3±1.2, 2.8±1.5 and 2.3±1.1, 9.2±3.9, 8.1±2.9 (p=0.03, p=0.001, p=0.012 and p=0.30). The mean PSA, NLR ,NMR values of the group 1 were significantly higher than those in group 2 (p=0.002). Gleason grade and pathological stage were significantly increases as NLR increases.

NLR and NMR in patients with BPH after second TRUS-guided biopsy were lower than that of those with a diagnosis of prostate cancer after the first TRUS-guided biopsy.White blood test subtypes can be considered for the decision to perform a second TRUSguided biopsy in patients with previous negative biopsy with persistently elevated PSA.
