The relevance of the BRAF V600E mutation in papillary thyroid carcinoma (PTC) as a negative prognostic factor is a subject of intense debate. This mutation has been associated with several clinicopathological features, but the lack of consistency among data does not support its usefulness as marker of tumor aggressiveness and poorer outcome. Due to the genetic heterogeneity of the tumor, both the occurrence and the allele percentage of the BRAF mutation should be considered to unravel this controversy.
