Abstract
Background
Ameloblastoma in 66% of the cases harbor a somatic mutation of the “mitogen-activated protein kinase” signaling pathway (BRAF V600E). In V600E mutations, BRAF is in the permanent “on” state and relays the growth-promoting signals independently of the EGFR pathway. Therefore, mutant BRAF represents a target for handful of new drugs.
Methods
We conducted a literature search, with the search terms “Vemurafenib, Dabrafenib, Ameloblastoma, and BRAF.” These included seven case reports with nine patients who underwent monotherapy with Dabrafenib or Vemurafenib or combination therapy with Dabrafenib and Trametinib.
Results
The patients age ranges from 10 years up to 86 years. The distribution of women and men is 4:5. Patients with an initial diagnosis of ameloblastoma, as well as recurrences or metastasized ameloblastoma were treated. Indications cover neoadjuvant therapy up to the use in metastasized patients in an irresectable state. Results ranging from “only” tumor size reduction to restitutio ad integrum.
Conclusion
We see the use of BRAF Inhibitors to reduce tumor size with consecutive surgical treatment as a reasonable option for therapy. However, we are aware that at present the data are based only on case reports with the longest follow-up of just 38 months. We encourage further clinical trials in the use of BRAF Inhibitors for selecting ameloblastoma patients in a multi-center setting.
