INTRODUCTION: It is not always possible to make a definitive diagnosis preoperatively with thyroid fine needle aspiration biopsy. Decision making is quite complicated in cases with atypical cells of undetermined significance. MicroRNAs have been shown to be associated with the development of neoplasia. For this purpose, we aimed to investigate the circulating microRNA 190 and microRNA 95-3P levels as a biomarker to distinguish benign and malign cases with preoperative atypical cells of undetermined significance diagnosis. METHODS: Patients with preoperative atypical cells of undetermined significance.diagnosis were included in the study. 29 malign and 29 benign patients were included. Venous blood samples isolated using a specific miRNA kit. RESULTS: According to the postoperative pathology results statistically significant between circulating miRNA 190 and miRNA 95-3p between cases with thyroid cancer. differences were detected. DISCUSSION AND CONCLUSION: It can be asserted that miRNA 95 and miRNA 190 assessment can help to differentiate thyroid cancer from benign thyroid nodules and may be useful in avoiding unnecessary surgery in patients with atypical cells of undetermined significance results.
