This is a very important article. Although a small sample, it opens the door to using a BRAF inhibitor for brain tumors that have the BRAF V-600 mutation. Note that this shouldn't be used in other mutations of BRAF, only the V-600 mutation. They found that using these drugs may actually speed up the tumor if they do not have the V-600 mutation.
