Mutational analysis of the BRAF gene (BRAF), especially BRAF V600E, is gaining much importance in neuro-oncology practice due to its diagnostic, prognostic and therapeutic implications. This genetic alteration has been described in a wide morphological spectrum of central nervous system tumors. In the present report we describe a BRAF V600E-mutated tumor with divergent morphological appearance comprising of anaplastic pleomorphic xanthoastrocytoma and astroblastoma. Both of these tumor entities are extremely rare and a combined morphology has not been described till now.

Background/aim: Colorectal cancer (CRC) has the third-highest incidence among human cancers. Advancements in chemotherapy and targeted therapy have improved the treatment outcomes for patients with CRC. However, the management of patients with unresectable metastatic CRC (mCRC) continues to be a significant challenge for clinicians worldwide, particularly for those with microsatellite stability (MSS) and the BRAF V600E mutation, as they are associated with the poorest prognosis.

Background: RAS/BRAF mutations, mismatch DNA repair complex deficiency (MMRd)/microsatellite instability (MSI), and CpG methylator phenotype (CIMP) are key molecular actors in colorectal carcinogenesis. To date, conflicting evidence about the correlations between these molecular features has been reported.
Materials And Methods: A retrospectively selected cohort of 123 CRCs was divided into 3 groups based on the molecular characteristics: MMR proficient (MMRp)/BRAF p.

Adjuvant radiation therapy (ART) for macroscopic regional nodal cutaneous melanoma has evolved. A significant step was the discovery of targeted therapies, particularly towards V600E-mutated melanoma, and immunotherapy under its different kinds. Prior to this, the defining trial was the Australia and New Zealand Melanoma Trials Group (ANZMTG) 01.

Papillary craniopharyngiomas are rare tumors prevalent to the precision oncology world due to their high rate of BRAF V600E mutations. Symptoms include vision loss, neuroendocrine dysfunction, and cognitive dysfunction. Treatment involves an interdisciplinary approach with surgery, radiation, and systemic treatment.
