The unique vulnerability of gliomas with BRAF mutations to targeted therapies, predominantly in adolescent and young adult populations, highlights the importance of accurate and timely identification of these mutations for appropriate treatment. Offering both immunohistochemical and sequencing methods for detection, as well as conducting multicenter collaborative studies, will be essential in achieving long term control of these rare tumors, while also exploring breakthrough resistance mechanisms for potential targeted treatments.
Opinion Statement Molecular heterogeneity has confounded attempts to target individual pathways in brain tumors. However, gliomas with BRAF mutations have been identified as being uniquely vulnerable to targeted therapies. Such mutations are predominantly seen in brain tumors of the adolescent and young adult population. Given that accurate and timely identification of such mutations is essential for offering appropriate treatment, treatment centers should offer both immunohistochemical and sequencing methods for detection of these mutations to guide treatment. Additional studies of these tumors at recurrence would also allow identification of breakthrough resistance mechanisms that may also be targetable for treatment. Due to the relative rarity of these tumors, multicenter collaborative studies will be essential in achieving long term control of these tumors.
