|Title||Case Report: Vemurafenib Treatment in Brain Metastases of BRAFS365L -Mutant Lung Papillary Cancer by Genetic Sequencing of Cerebrospinal Fluid Circulating Tumor DNA Detection.|
|Abstract Text||BRAF mutations, primarily sensitizing mutations, such as BRAFV600E , have been proven to response to the BRAF inhibitor, Dabrafenib combined with trametinib therapy, but there have been no data demonstrating that it has activity against NSCLC-related brain metastases (BM). How patients harboring BRAFS365L mutation (a rare mutation following BRAFV600E -inhibitor treatment) in NSCLC is unknown. Vemurafenib, another BRAF inhibitor, can reverse the resistance that develops with the BRAFS365L mutation following dabrafenib combined with trametentinib treatment in melanoma, but none has been reported in NSCLC. Lung papillary cancer, as a rare typing, occupies about 4% of NSCLC. Hence, we reported the first case of a patient with BM of lung papillary carcinoma harboring a BRAFV600E mutation who benefited from dabrafenib combined with trametinib, and following the development of the BRAFS365L mutation, vemurafenib remained an effective therapeutic option. Moreover, we found that the next-generation sequencing (NGS) of cerebrospinal fluid (CSF) circulating tumor DNA (ctDNA) may potentially provide more accurate information about intracranial lesions than ctDNA in the blood serum, which will be a better detection method.|

|BRAF||S365L||missense||unknown||BRAF S365L does not lie within any known functional domains of the Braf protein (UniProt.org). S365L has been demonstrated to occur as a secondary drug resistance mutation (PMID: 34178685), but has not been biochemically characterized and therefore, it's effect on Braf protein function is unknown (PubMed, Nov 2023).||Y|

|BRAF V600E||lung papillary adenocarcinoma||predicted - sensitive||Dabrafenib + Trametinib||Case Reports/Case Series||Actionable||In a clinical case study, Tafinlar (dabrafenib) and Mekinist (trametinib) combination treatment resulted in regression of the lesions in the chest, abdomen and brain in a patient with lung papillary carcinoma harboring BRAF V600E but progression was observed 3 months later (PMID: 34178685).||34178685|
|BRAF S365L BRAF V600E||lung papillary adenocarcinoma||predicted - resistant||Dabrafenib + Trametinib||Case Reports/Case Series||Actionable||In a clinical case study, a patient with lung papillary carcinoma harboring BRAF V600E who previously responded to Tafinlar (dabrafenib) and Mekinist (trametinib) treatment was found to have acquired BRAF S365L upon disease progression (PMID: 34178685).||34178685|
