Serum microRNA-205 as a novel biomarker for cervical cancer patients
OBJECTIVE: Serum microRNAs (miRNAs) are a novel class of diagnostic and prognostic biomarkers for numerous cancers. However, the level and clinical relevance of circulating miR-205 transcripts in human serum of cervical cancer patients are unclear. The purpose of this study was to determine serum mi...

description | OBJECTIVE: Serum microRNAs (miRNAs) are a novel class of diagnostic and prognostic biomarkers for numerous cancers. However, the level and clinical relevance of circulating miR-205 transcripts in human serum of cervical cancer patients are unclear. The purpose of this study was to determine serum miR-205 levels in cervical cancer patients and explore its association with clinicopathological factors and prognosis. METHODS: Serum miR-205 expression was investigated in 60 cervical cancer patients and 60 healthy normal controls by using real-time PCR. Correlations between miR-205 expression and the clinicopathological features and prognosis of cervical cancer patients were then evaluated. Receiver operating characteristic curves were used to evaluate the sensitivity and specificity of serum miR-205. RESULTS: Serum miR-205 was significantly upregulated in cervical cancer patients compared with healthy donors (p < 0.01), and a high level of miR-205 expression was correlated with poor tumor differentiation (p = 0.009), lymph node metastasis (p = 0.015) and increased tumor stage (p = 0.001). The serum miR-205 level was capable of separating advanced stage from early stage metastatic cervical cancer from non-metastatic samples and poorly differentiated tumors from differentiated tumors with an area under the curve values of 0.74, 0.694 and 0.717, respectively. The expression of miR-205 was also higher in the cervical cancer tissues compared with the para-carcinoma tissues. In addition, Kaplan-Meier survival analysis showed that cervical cancer patients with high miR-205 expression tended to have shorter overall survival. In multivariate Cox regression analysis, miR-205 was identified as an independent prognostic marker. CONCLUSIONS: Serum miR-205, which is upregulated in cervical cancer, represents a predictive biomarker for the prognosis of cervical cancer patients. |
