The integration of targeted therapy into the multimodal management of craniopharyngiomas represents a significant advancement in the field of neuro-oncology. Historically, the management of these tumors has been challenging due to their proximity to vital brain structures, necessitating a delicate balance between tumor control and the preservation of neurological function. Traditional treatment modalities, such as surgical resection and radiation, while effective, carry their own set of risks, including potential damage to surrounding healthy tissues and the potential for long-term side effects. Recent insights into the molecular biology of craniopharyngiomas, particularly the discovery of the BRAF V600E mutation in nearly all papillary craniopharyngiomas, have paved the way for a targeted systemic treatment approach. However, advances have been limited for adamantinomatous craniopharyngiomas. The success of BRAF/MEK inhibitors in clinical trials underscores the potential of these targeted therapies not only to control tumor growth but also to reduce the need for more invasive treatments, potentially minimizing treatment-related complications. However, the introduction of these novel therapies also brings forth new challenges, such as determining the optimal timing, sequencing, and duration of targeted treatments. Furthermore, there are open questions regarding which specific BRAF/MEK inhibitors to use, the potential need for combination therapy, and the strategies for managing intolerable adverse events. Finally, ensuring equitable access to these therapies, especially in healthcare systems with limited resources, is crucial to prevent widening healthcare disparities. In conclusion, targeted therapy with BRAF/MEK inhibitors holds great promise for improving outcomes and quality of life for patients with BRAF-mutated craniopharyngiomas. However, additional research is needed to address the questions that remain about its optimal use and integration into comprehensive treatment plans.

The intrinsic ability of cancer cells to evade death underpins tumorigenesis, progression, metastasis and the survival of drug-tolerant persister (DTP) cells. Herein, we discovered that when activated, the small GTPase ARF6 plays a central role in tumor survival by facilitating expression of the BRAF oncoprotein. Tumor-specific deletion caused a significant reduction in BRAF protein and MAPK signaling and prevented rapid tumor progression.

Background: -mutant gliomas can be targeted therapeutically using BRAF-selective inhibitors, yet responses are often transient due to adaptive resistance through reactivation of RAS-ERK signaling. Here, we evaluate the role of SHP2, a central regulator of RAS activity, and SHP2 inhibitors in overcoming resistance to BRAF inhibitors in glioma.
Methods: RNAseq and protein expression in human tissue samples and glioma cell lines were used to identify resistance mechanisms.

Background: Ameloblastoma is a benign odontogenic tumor that predominantly occurs in the mandible and is frequently associated with the BRAFV600E mutation, which activates the mitogen-activated protein kinase (MAPK) signaling pathway. These mutations indicate potential targets for molecular therapies. This systematic review evaluated the effectiveness of molecular-targeted therapies, particularly BRAF inhibitors such as dabrafenib and vemurafenib, in the treatment of ameloblastoma and their effects on clinical outcomes and quality of life.

Background: V-Raf murine sarcoma viral oncogene homolog B1 (BRAF) mutations are present in approximately 5% of Japanese patients with colorectal cancer (CRC) who receive BRAF-targeted triplet therapy, consisting of encorafenib (a BRAF inhibitor), binimetinib (a mitogen-activated protein kinase inhibitor [MEKi]), and cetuximab. This combination therapy is associated with an increased risk of cardiac dysfunction (CD), primarily attributed to MEKi. However, the detailed clinical course of this adverse event remains unclear.

Objective: To evaluate the efficacy and safety of targeted molecular therapy for recurrent and refractory papillary craniopharyngioma (PCP) and explore its potential as a neoadjuvant treatment.
Methods: This systematic and narrative review was performed following PRISMA guidelines to evaluate BRAF and MEK inhibitors in treating PCP. PubMed, EMBASE, and Web of Science were searched up to July 2025.
