ABSTRACT
PURPOSE:
The aim of this study was to evaluate the diagnostic value of a peptide nucleic acid (PNA)-mediated PCR clamping method for the detection of BRAFV600E mutations in fine needle aspiration cytology (FNAC).METHODS:
One hundred sixty four patients underwent FNAC to evaluate BRAFV600E mutations between April 2011 and November 2011. Among them, forty-two patients were diagnosed with papillary thyroid carcinoma in a permanent pathologic specimen. A PNA-mediated PCR clamping method and a Dual-Priming Oligonucleotide (DPO)-based Real-time PCR method were used to detect the BRAFV600E mutation. We compared the result of mutation between the two methods.RESULTS:
A BRAF mutation was found in 31 samples created by the PNA-mediated PCR clamping method, and in 28 samples in the DPO-based Real-time PCR method. The rate of BRAF mutation was 73.8% in association with the PNA-mediated PCR clamping method, and 66.7% in association with the DPO-based Real-time PCR method. There was no statistical differences between the two methods (P>0.05).CONCLUSION:
The PNA-mediated PCR clamping method may be an alternative to the DPO-based Real-Time PCR method for detection of BRAF mutations in thyroid nodules.
