Abstract:
Objective To investigate the role of BRAFV600E mutation in diagnosis of thyroid nodules when it is inconsonant with cytological results. Methods This study included 9837 patients who underwent US-FNA. We mainly analyzed 239 cases with benign or indeterminate cytology, but having a detection of BRAFV600E muta-tion. BRAFV600E mutation analysis was performed using a Amplification Refractory Mutation System Polymerase Chain Reaction. Results In 93 nodules with benign cytology results but positive BRAFV600E mutation, 84 nodules were malignant. Based on the results, US-FNA combined with BRAFV600E mutation analysis will improve sensitivity (Se=94.03％)and negative predictive value (NPV=2.69％) of the thyroid nodules diagnosis than using US-FNA alone(Se=71.03％, NPV=20.76％). Conclusion BRAFV600E mutation analysis is an important tool in the diagnosis of PTC with high sensitivity and NPV. When facing patients with benign or indeterminate cytology but positive BRAFV600E mutation, thyroidectomy should be considered.
