Efficacy of Dabrafenib for three children with brainstem BRAFV600E positive ganglioglioma.

Dabrafenib is effective and seemingly safe and well tolerated in our three patients. We observed sustained chemosensitivity even when re-introducing this kinase inhibitor after its discontinuation after 2 years of therapy. These cases indicate the need to re-evaluate the timing and means of Dabrafenib discontinuation in pediatric patients with BRAFV600E mutated gangliogliomas and better assess the future implications of its long-term use.
