Abstract:
Objective:To investigate the correlation of preoperative peripheral lymphocyte-to-monocyte ratio(LMR)with the biochemical relapse and prognosis in prostate cancer(PCa)patients treated with endocrine therapy after radical prostatectomy(RP).Methods:Clinical data of 306 prostate cancer patients treated with endocrine therapy after radical prostatectomy were retrospectively analyzed in our hospital from June 2008 to June 2019.The end point of observation was biochemical relapse-free survival(RFS)in all patients receiving RP.The best cutoff value of preoperative LMR was calculated by receiver operating characteristic(ROC)curve.All patients were divided into the high LMR group(LMR≥2.8, n=93, 30.4%)and the low LMR group(LMR<2.8, n=213, 69.6%). The differences in clinical indicators of PCa were compared between high and low LMR groups.CoX regression model on the risk ratio of single and multiple factors were used to analyze the survival effect of preoperative LMR on the prognosis of PCa patients undergoing endocrine therapy after operation.Results:The median follow-up time was ranged from 4 to 132 months.The area under the ROC curve of LMR was 0.582(95% CI: 0.511-0.652, P<0.05), and the cutoff value of the preoperative LMR was 2.8, which was significantly associated with clinical T stage( P=0.023)and lymphatic metastasis( P=0.031). Kaplan-Meier analysis demonstrated that the low LMR group had a short RFS and a poor prognosis(31.0 months vs.38.5 months)than those in the high LMR group( P<0.05). Lymphatic metastasis and preoperative LMR were independent predictors for RFS in PCa patients treated with endocrine therapy after radical prostatectomy. Conclusions:Preoperative peripheral LMR can be used as an auxiliary indicator of the prognosis in PCa patients treated with endocrine therapy after radical prostatectomy.
