摘要:

目的 探讨血清微小RNA-598-3p(miR-598-3p)检测及miR-598-3p与糖类抗原153(CA153)联合检测在乳腺癌诊断中的意义。方法 收集2013年1月—2014年9月在台州市中心医院确诊的100例乳腺癌患者、45例乳腺良性疾病患者及40名健康对照者血清标本,应用实时荧光定量聚合酶链反应(PCR)检测血清miR-598-3p的表达水平,应用化学发光法检测血清CA153水平,应用受试者工作特征(ROC)曲线分析血清miR-598-3p、CA153及二者联合检测对乳腺癌诊断的敏感性和特异性。结果 乳腺癌患者血清miR-598-3p的表达水平下调,CA153水平升高,与健康对照组比较,差异均有统计学意义(P<0.01)。miR-598-3p的表达量与乳腺癌TNM分期无相关性(P>0.05)。ROC曲线分析结果显示,miR-598-3p诊断乳腺癌的敏感性和特异性分别为95.0%、85.0%;CA153诊断乳腺癌的敏感性和特异性分别为66.0%、65.0%。二者联合检测诊断乳腺癌的敏感性和特异性分别为96.0%、70.0%。结论 miR-598-3p对乳腺癌的诊断具有良好的敏感性和特异性,联合CA153检测可以提高对乳腺癌的诊断效能。

Abstract:

Objective To investigate the combined determination of serum microRNA-598-3p (miR-598-3p) and carbohydrate antigen 153 (CA153)in the diagnosis of breast carcinoma. Methods A total of 100 breast carcinoma patients,45 benign breast disease controls and 40 healthy controls in Taizhou Central Hospital from January 2013 to September 2014. The level of serum miR-598-3p was determined by real-time fluorescence quantitation polymerase chain reaction (PCR). The level of serum CA153 was determined by chemiluminescence. Receiver operating characteristic (ROC) curve was used to evaluate the sensitivities and specificities of serum miR-598-3p and CA153 single and combined determinations for diagnosing breast carcinoma. Results Compared to healthy control group,serum miR-598-3p was down-regulated,and serum CA153 was up-regulated in breast carcinoma group (P<0.01). There was no correlation between serum miR-598-3p level and different TNM stages of breast carcinoma (P>0.05). ROC curve showed that the sensitivities of serum miR-598-3p and CA153 were 95.0% and 66.0%,and the specificities were 85.0% and 65.0%,respectively. The sensitivity and specificity of the combined determination of serum miR-598-3p and CA153 were 96.0% and 70.0%. Conclusions MiR-598-3p shows a good sensitivity and specificity for diagnosing breast carcinoma,and the combined determination of serum miR-598-3p and CA153 could improve diagnostic efficiency.
