Combination therapy with BRAF and MEK inhibitors (BRAF/MEKi) has shown significantly prolonged progression-free survival (PFS) and overall survival (OS) for BRAF mutated melanoma. Over 90% of the activating mutations are BRAF or BRAF changes. There are no reports of BRAF in Japanese patients with melanoma. The third most common BRAF mutation is BRAF. In this case, we detected the BRAF mutation with FoundationOne CDx in a Japanese patient with melanoma.. The patient was treated with BRAF/MEKi and maintained stable disease status for 1 year.

Background: Rathke cleft cysts (RCCs) are benign sellar/suprasellar lesions that result from mucin-secreting vestigial remnants within the pars intermedia of the pituitary gland. When symptomatic, they can present with retro-orbital headaches, visual field defects, and/or pituitary dysfunction.
Observations: A 35-year-old female presented with subacute retro-orbital headache, right ptosis, and blurred vision.

Background: Dabrafenib plus trametinib (Dab + Tram) is an approved targeted therapy in patients with mutated metastatic non-small cell lung cancer (NSCLC). Here, we report the efficacy, safety, and quality of life (QoL) results of Dab + Tram treatment in Chinese patients with mutation-positive metastatic NSCLC.
Methods: This is a single-arm, open-label, multicentre, phase II study (NCT04452877).

Background: The combination therapy of the B-Raf proto-oncogene (BRAF) inhibitor dabrafenib and the mitogen-activated protein kinase kinase (MEK) inhibitor Trametinib has shown favorable outcomes in patients initially identified with BRAF mutations. However, there are currently no large-scale study data focusing on the use of a triple therapy regimen of epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) plus dabrafenib and trametinib in patients with newly concomitant BRAF mutations after acquiring resistance to EGFR-TKIs. Our study aimed to explore the efficacy and safety of the triple therapy regimen through a multi-center real-world experience.

Combining an integrated thyroid cancer single-cell sequencing atlas with spatial transcriptomics and bulk RNA-sequencing, we define stromal cell subpopulations and tumor-stromal cross-talk occurring across the histologic and mutational spectrum of thyroid cancer. We identify distinct inflammatory and myofibroblastic cancer-associated fibroblast (iCAF and myCAF) populations and perivascular-like populations.

The current study established the first in vitro Encorafenib resistance protocol in BRAF-mutated malignant melanoma (MM) cells and investigated the resistance-related mechanisms. After establishing Encorafenib-resistant A375-MM cells, resistant-related mechanisms were investigated using WST-1, Annexin V, cell cycle, morphological analysis, live-cell, Western blot, RNA-Seq, transmission electron microscopy-(TEM), oxidative stress and iron colorimetric assay. The most resistant group, called A375-R, was determined in the cells treated with a constant dose of 10 nM over 3 months.
