Analysis of immunocytochemical and molecular BRAF expression in thyroid carcinomas: A cytohistologic institutional experience

Abstract

Although it has limitations, the VE1 antibody represents a feasible first-line approach for evaluating BRAF mutation status and may be a valid tool in the selection of samples for molecular analysis. The current report highlights the statistically significant difference between molecular and VE1 positivity in PTC (P < .0001). Nevertheless, in the authors' experience, BRAF mutations are more accurate for identifying VE1-negative cases.
