Abstract Text | The BRAF-V600E genetic mutation offers a potential targeted therapy for the treatment of papillary craniopharyngiomas.A 35-year-old man underwent a craniotomy and subtotal resection of a large BRAF-V600E-positive papillary craniopharyngioma before referral to our institution. Our treatment included the BRAF-V600 inhibitor dabrafenib mesylate (75 mg, twice/day) and trametinib dimethyl sulfoxide (2 mg/day). The residual tumour decreased in size by 95% over 21 months without negative side effects.We reviewed the literature on BRAF-V600E inhibition as a non-invasive method of treating papillary craniopharyngiomas harbouring the BRAF-V600E mutation. |
