Abstract:
Objective The aim of our study was to explore the relationship between prostate cancer and four serum markers,including Prostate specific antigen (PSA),Beta 2 Microglobulin (β2M),Neutrophil-to-lympochyte ratio (NLR) and Lactic dehydrogenase (LDH),and their variation rules in development of prostate cancer.Then to find one or more markers that can increase the sensitivity and specificity of diagnosis to provide reference for clinic.Methods A total of 149 prostate cancer patients,40 patients with benign prostatic hyperplasia,80 healthy subjects in our hospital were analyzed,and subsequent the T-PSA,F-PSA,β2M,LDH and NLR were measured.The correlation between these markers and prostate cancer as well as its different types and Gleason score was assessed statistically.We determined the cut-off point of the NLR and T-PSA according to the specificity and sensitivity levels derived from area under receiver operator characteristic (ROC) curve.Results The level of T-PSA was significantly higher in patients of prostate cancer and benign prostatic hyperplasia,and the level of NLR was higher only in patients of prostate cancer.Based on the area under ROC,the cut-off value of T-PSA was determined to be 4.625 ng/ml,and NLR was 2.11,and combined NLR and T-PSA can increase the specificity of diagnose.There is a statistical difference in Gleason scores in patients with different NLR of prostate cancer (P =0.030).Conclusions It could increased the specificity when combined NLR and T-PSA to diagnose prostate cancer.And NLR has positive correlation with the prognosis of patients of prostate cancer as well.
