ABSTRACT

Background

Activating somatic mutation of the BRAFV600E has been identified as the most common genetic event in papillary thyroid carcinoma (PTC) with a variable frequency (32–87 %) in different series by different methods. The BRAFV600E mutation is associated with various clinicopathological parameters. The mutation is an important factor for the management of the PTC patients. The objective of this study was to detect the BRAFV600E mutation in PTCs by peptide nucleic acid (PNA) clamp real-time PCR and to analyze the results with clinicopathological parameters.

Methods

We performed genetic analysis of BRAFV600E by PNA clamp real-time PCR in 211 PTCs in Korea, stratified by clinicopathological parameters.

Results

The BRAFV600E mutation was detected in 90 % of PTC cases, and it occurred significantly more often in female patients than in male patients (p = 0.001). The clinicopathological parameters of age, tumor size, and disease stage were not associated with the BRAFV600E mutation, while extrathyroid invasion (p = 0.031), lymph nodal metastasis (p = 0.002), and tumor multiplicity (p = 0.020) were.

Conclusions

The prevalence (90 %) of the BRAFV600E mutation in this study is the highest ever reported, confirming the key role of this mutation in PTC tumorigenesis. The BRAFV600E mutation was associated with aggressive clinical behaviors including extrathyroid invasion, lymph nodal metastasis and tumor multifocality. The PNA clamp real-time PCR method for the BRAFV600E mutation detection is sensitive and is applicable in a clinical setting.
