BRAF in primary and recurrent papillary thyroid cancers: the relationship with 131I and 2-[18F]fluoro-2-deoxy-d-glucose uptake ability

Abstract

BRAF mutations are more common in thyroid recurrences with no (131)I uptake than in (131)I-positive cases. They are correlated with the ability to concentrate (18)F-FDG, and they can appear, albeit rarely, as a de novo event in the course of PTC recurrences.
