Expression level of miRNA-210-3p in cervical cancer and its prognostic potential

OBJECTIVE: The purpose of this study was to detect the expression level of microRNA-210-3p (miRNA-210-3p) in cervical cancer (CC) tissues and its clinical significance. PATIENTS AND METHODS: Expression levels of miRNA-210-3p in collected CC tissues, normal cervical tissues and cervical intraepithelial neoplasia (CIN) tissues (CIN I, CIN II, and CIN III) were tested by reverse transcriptase-polymerase chain reaction (RT-PCR). The relationship between miRNA-210-3p level and clinical data of CC patients was analyzed. Moreover, the receiver operating characteristic (ROC) was introduced for assessing the diagnostic potential of miRNA-210-3p in CC. RESULTS: Results revealed that miRNA-210-3p level was higher in CC tissues relative to normal cervical tissues and CIN tissues. Its expression was not correlated with age, pathological subtype, and tumor size of CC patients. However, miRNA-210-3p level was closely linked to FIGO stage, tumor differentiation, and lymphatic metastasis in CC. Based on depicted ROC, miRNA-210-3p was able to distinguish CC from normal cervical tissues and CIN tissues. CONCLUSIONS: MiRNA-210-3p is upregulated in CC, and its level is closely correlated with FIGO stage, tumor differentiation, and lymphatic metastasis in CC patients. Besides, miRNA-210-3p produces a pronounced diagnostic efficacy, so it can be utilized as a novel hallmark for diagnosing CC and predicting the disease progression.
