Abstract excerpt

BACKGROUND: This study evaluated the efficacy and safety of dabrafenib or trametinib in pediatric Langerhans cell histiocytosis (LCH) patients with skeletal involvement, for whom conventional therapies offer limited benefit. METHODS: A single-center retrospective analysis was conducted on 30 children with pathologically confirmed, bone-involved LCH who received dabrafenib or trametinib due to severe, refractory,...
