BRAF inhibitors, such as vemurafenib and dabrafenib and a MEK inhibitor trametinib are the most effective, approved treatments for BRAF positive melanoma. [ 131 ] [ 124 ] Melanoma tumors can develop resistance during therapy which can make therapy no longer effective, but combining the use of BRAF and MEK inhibitors may create a fast and ...

A phase III trial (vs dacarbazine) in patients with previously untreated metastatic melanoma showed an improved rates of overall and progression-free survival. [18] In June 2011, positive results were reported from the phase III BRIM3 BRAF-mutation melanoma study. [19] The BRIM3 trial reported good updated results in 2012. [20]
V600E is a mutation of the BRAF gene in which valine (V) is substituted by glutamic acid (E) at amino acid 600. [1] [2] It is a driver mutation in a proportion of certain diagnoses, including melanoma, [3] [4] hairy cell leukemia, [5] [6] papillary thyroid carcinoma, [7] [8] colorectal cancer, [9] non-small-cell lung cancer, [10] [11] Langerhans cell histiocytosis, [12] Erdheim–Chester ...
BRAF encodes a serine/threonine kinase that is involved in the RAS-RAF-MAPK growth signaling pathway. Mutations in BRAF cause constitutive phosphorylation and activity in 59% of melanomas. Before BRAF, the genetic mechanism of melanoma development was unknown and therefore prognosis for patients was poor. [71]
