The role of blood neutrophil count and the neutrophil

It is apparent that prostate cancer has harmful effects on the erythrocytes, leucocytes, and platelets. In addition, it has been suggested that the toxic granules in neutrophils lead to inflammation in the cancerous tissues besides the activation of monocytes, so in this study we aimed to evaluate the blood neutrophil count besides the neutrophil-to-lymphocyte ratio as a predictive factor for prostate biopsy results and their relationship with prostate cancer grade in patients undergoing biopsy of the prostate. For all men with irritative lower urinary tract symptoms visiting Hasheminezhad Hospital from January to July 2015, in case of having a suspicious digital rectal examination or aged above 40？years, prostate-specific antigen was requested and in case of abnormal results, they underwent prostate biopsy. In order to examine the study hypothesis, the blood neutrophil count and the neutrophil-to-lymphocyte ratio were measured and compared with the abnormal prostate-specific antigen results and suspicious digital rectal examination. Among the 500 referred samples for biopsy, 352 (70.4%) had a negative biopsy result, while it was positive in the other 148 (29.6). The mean neutrophil count showed no statistical difference regarding the biopsy results (p？=？0.381). When measuring the neutrophil-to-lymphocyte ratio again with biopsy results, no statistically significant difference was obtained based on the biopsy results (p？=？0.112). Neutrophil count and neutrophil-to-lymphocyte ratio cannot be predictive factors for positive prostate cancer biopsy
