摘要:

目的 探讨尿液外泌体miR-214表达在透明细胞肾细胞癌(ccRCC)诊断和预后评估中的价值。方法 选取2021年2月—2022年2月临汾市中心医院接受手术治疗的ccRCC患者124例(ccRCC组)和肾脏良性疾病(肾炎、肾结石、肾囊肿等)患者124例(对照组)。收集所有患者的临床资料,并检测术前晨尿中段尿外泌体miR-214相对表达量。采用受试者工作特征(ROC)曲线评价尿液外泌体miR-214诊断ccRCC的效能。采用Kaplan-Meier生存曲线评估ccRCC患者的生存情况。采用Cox回归分析评估ccRCC患者总生存率的影响因素。结果 ccRCC组尿液外泌体miR-214相对表达量显著低于对照组(P<0.001)。尿液外泌体miR-214诊断ccRCC的曲线下面积(AUC)为0.86,最佳临界值为0.65,敏感性为86.7%,特异性为82.2%。不同TNM分期、Fuhrman分级和有无淋巴转移、远隔转移的ccRCC患者之间尿液外泌体miR-214相对表达量差异均有统计学意义(P<0.05)。miR-214低表达组总生存率显著低于miR-214高表达组(P<0.001)。尿液外泌体miR-214相对表达量≤0.65、TNM分期Ⅲ~Ⅳ期、Fuhrman分级Ⅲ~Ⅳ级、有淋巴转移、有远隔转移是ccRCC患者总生存率降低的独立危险因素[风险比(HR)值分别为1.96、1.55、1.80、1.52、1.24,95%可信区间(CI)分别为1.07~2.83、1.03~2.38、1.06~3.07、1.13~2.68、1.09~2.18,P<0.05]。结论 ccRCC患者尿液外泌体miR-214呈低表达,且与肿瘤发生、发展和转移密切相关,可作为ccRCC的诊断标志物和预后评估指标。

Abstract:

Objective To investigate the role of urinary exosome miR-214 expression in the diagnosis and prognosis assessment of clear cell renal cell carcinoma(ccRCC). Methods A total of 124 patients with ccRCC(ccRCC group) and 124 patients with renal benign diseases(nephritis,kidney stones,renal cysts and so on)(control group) were enrolled from Linfen Central Hospital from February 2021 to February 2022. The clinical data of all patients were collected,and the relative expression level of urinary exosome miR-214 in mid-urine in the morning before surgery was determined. Receiver operating characteristic(ROC) curve was used to evaluate the diagnostic efficacy of urinary exosome miR-214 in ccRCC. Kaplan-Meier survival curve was used to evaluate the survival of ccRCC patients. Cox regression analysis was used to evaluate the factors affecting overall survival in ccRCC patients. Results The relative expression of urinary exosome miR-214 in ccRCC group was lower than that in control group(P<0.001). The area under curve(AUC) of urinary exosome miR-214 for the diagnosis of ccRCC was 0.86,the optimal cut-off value was 0.65,the sensitivity was 86.7%,and the specificity was 82.2%. There was statistical significance in the relative expression of urinary exosome miR-214 among ccRCC patients with different TNM stages,Fuhrman grades,lymphatic metastasis and distant metastasis(P<0.05). The overall survival rate of low miR-214 expression group was lower than that of high miR-214 expression group(P<0.001). The relative expression level of urinary exosome miR-214 ≤0.65,TNM stage Ⅲ-Ⅳ,Fuhrman grade Ⅲ-Ⅳ,lymphatic metastasis and distant metastasis were independent risk factors for decreased overall survival in ccRCC patients [hazard ratios(HR) were 1.96,1.55,1.80,1.52 and 1.24,95% confidence intervals(CI) were 1.07-2.83,1.03-2.38,1.06-3.07,1.13-2.68 and 1.09-2.18,respectively,P<0.05]. Conclusions The low expression of urinary exosome miR-214 in patients with ccRCC is related to tumorigenesis,development and metastasis,which can be used as a diagnostic marker and prognostic indicator for ccRCC.
