Circulating miRNA 27a and miRNA150-5p; a noninvasive approach to endometrial carcinoma

Abstract

The search for novel non-invasive biomarkers such as epigenetic molecular markers is new hope for common and burdensome cancers. We aim to assess serum expression of miRNA 27a and miRNA150-5p in endometrial cancer patients. Serum was drawn for 36 un-intervened endometrial cancer patients scheduled for hysterectomy and 35 controls. miRNA 27a and miRNA150-5p were measured by real time reverse transcription polymerase chain reaction. Significant overexpression of both miRNA in patients (p < 0.001). At cutoffs 0.2872 & > 1.02, miRNA 27a showed 100% sensitivity, specificity, positive and negative predictive values. miRNA150-5p showed 88.89% sensitivity, 100% specificity, 100% positive and 78.9% negative predictive values. Areas under curve were 1.0 for miRNA 27a, 0.982 for miRNA 150 performing much better than Ca125. miRNA 27a was significantly associated with type I endometroid endometrial cancer. Conclusion: miRNA 27a and miRNA-150-5P can be suggested as promising biomarkers of endometrial cancer possibly part of a miRNA panel for management.
