Abstract
The mitogen-activated protein kinase (MAPK) pathway is a key driver in many histiocytic disorders, including Langerhans cell histiocytosis (LCH) and Erdheim-Chester disease (ECD). This has led to successful and promising treatment with targeted therapies, including BRAF inhibitors and MEK inhibitors. Additional novel inhibitors have also demonstrated encouraging results. Nevertheless, there are several problems concerning targeted therapy that need to be addressed. These include, among others, incomplete responsiveness and the emergence of resistance to BRAF inhibition as observed in other BRAF-mutant malignancies. Drug resistance and relapse after treatment interruption remain problems with current targeted therapies. Targeted therapy does not seem to eradicate the mutated clone, leading to inevitable relapes, which is a huge challenge for the future. More fundamental research and clinical trials are needed to address these issues and to develop improved targeted therapies that can overcome resistance and achieve long-lasting remissions.

Comprehensive narrative Review Articles and shorter Leading Articles discussing relevant clinically established as well as emerging agents and pathways.
Current Opinion articles that place interesting areas in perspective.
Therapy in Practice articles that provide a guide to the optimum management of a condition and highlight practical, clinically relevant considerations and recommendations.
Systematic Reviews that use explicit, systematic methods as outlined by the PRISMA statement.
Adis Drug Reviews of the properties and place in therapy of both newer and established targeted drugs in oncology.
