BRAF addiction of thyroid cancers makes them therapeutically vulnerable

Researchers have found that thyroid cancers with BRAF mutations are exquisitely dependent on the BRAF signaling pathway for viability. Treatments targeting this pathway can restore radioiodine incorporation, suggesting a new therapeutic approach for patients with BRAF-positive papillary thyroid carcinomas.
