血清miRNA-21-5p、miRNA-5189-5p表达水平对行根治性前列腺切除术老年前列腺癌患者预后的评估价值

Prognostic value of serum miRNA-21-5p and miRNA-5189-5p expression levels in elderly patients with prostate cancer after radical prostatectomy

目的分析血清微小RNA(miRNA)-21-5p、miRNA-5189-5p表达水平对行腹腔镜根治性前列腺切除术(LRP)的老年前列腺癌患者预后的评估价值。方法选取2014年1月至2018年9月该院收治的行LRP治疗的213例老年前列腺癌患者作为研究对象,根据5年随访结局将患者分为预后优良组(87例)和预后不良组(126例)。收集患者术前临床基线资料及血清miRNA-21-5p、miRNA-5189-5p表达水平。采用Logistic回归分析筛选影响患者预后的因素,并以独立危险因素构建预后预测模型,绘制受试者工作特征(ROC)曲线分析其预测价值。结果多因素Logistic回归分析结果显示,患者血清前列腺特异性抗原(PSA)水平、切缘阳性、血清miRNA-21-5p与miRNA-5189-5p表达水平均为行LRP的老年前列腺癌患者预后的独立危险因素(P<0.05),以独立危险因素构建联合预测模型,各因素单独预测行LRP的老年前列腺癌患者预后的曲线下面积均小于4项联合(P<0.05)。结论血清miRNA-21-5p、miRNA-5189-5p表达水平对行LRP的老年前列腺癌患者预后的预测具有较高价值。

Objective To analyze the prognostic value of serum microRNA(miRNA)-21-5p and miRNA-5189-5p expression levels in elderly patients with prostate cancer after laparoscopic radical prostatectomy(LRP).Methods A total of 213 elderly prostate cancer patients treated with LRP from January 2014 to September 2018 in the First Affiliated Hospital of Hainan Medical College were retrospectively selected as the study objects.According to the 5-year follow-up outcome,the patients were divided into good prognosis group(87 cases)and poor prognosis group(126 cases).The preoperative clinical baseline data and the expression levels of serum miRNA-21-5p and miRNA-5189-5p were collected.Logistic regression analysis was used to screen the factors affecting the prognosis of patients.The prognostic prediction model was constructed with independent risk factors,and the predictive value was analyzed by drawing receiver operating characteristic(ROC)curve.Results Multivariate Logistic regression analysis showed that serum prostate specific antigen(PSA)level,positive incisal margin,and expression levels of miRNA-21-5p and miRNA-5189-5p were independent risk factors for the prognosis of elderly prostate cancer patients receiving LRP(P<0.05).The combined prediction model was established based on independent risk factors,and the area under the curve of each factor alone predicting prognosis of elderly prostate cancer patients receiving LRP was less than that of four combined prediction(P<0.05).Conclusion The expression levels of serum miRNA-21-5p and miRNA-5189-5p are of high value in predicting the prognosis of elderly prostate cancer patients after LRP.
