Abstract:

Objective To investigate the roles of pretreatment platelet/lymphocyte ratio(PLR),neutrophil/lymphocyte ratio(NLR) and lymphocyte/monocyte ratio(LMR) in the prognosis of prostate cancer patients. Methods The clinical data of 144 patients with prostate cancer were enrolled. Pretreatment platelet,lymphocyte,monocyte and neutrophil were determined. PLR,NLR and LMR were calculated. Patients diagnosed with prostate cancer were enrolled for a 3-year follow-up. Kaplan-Meier method was used for survival analysis. Cox regression analysis was used to evaluate the correlations between PLR,NLR and LMR with the prognosis of prostate cancer. The correlations between PLR,NLR and LMR with Gleason scores were analyzed by Pearson analysis. Results PLR,NLR and LMR of 144 prostate cancer patients were 4.71(1.21-62.14),4.77(1.34-57.41) and 2.83(0.91-39.10),respectively. The subjects were grouped according to the median of the measured values of the 3 indicators. In patients with high PLR and low LMR,the 3-year overall survival rate,progression-free survival rate and tumor-specific survival rate were decreased(P<0.001). There was no statistical significance in 3-year overall survival rate,progression-free survival rate and tumor-specific survival rate of prostate cancer patients between high and low NLR groups(P>0.05). Cox regression analysis showed that high PLR,low LMR,age,alcohol history,hypertension history and TNM stage were prognostic factors for 3-year overall survival rate,progression-free survival rate and tumor-specific survival rate in prostate cancer patients(P<0.05). Pearson analysis showed that there were positive correlations between PLR and NLR with Gleason score(r=0.26 and 0.23,P<0.01) and a negative correlation between LMR and Gleason score(r=-0.41,P<0.000 1). Conclusions PLR and LMR before treatment can be used as prognostic indicators for patients with prostate cancer,and patients with pretreatment high PLR and low LMR have poor prognosis.
