Zelboraf for other mutations that BRAF-E

Zelboraf(vemurafenib) is anti BRAF kinase inhibitor. ZELBORAF™ is indicated for the treatment of patients with unresectable or metastatic melanoma with BRAFV600E mutation as detected by an FDA-approved test.  More than 30 mutations of the BRAF gene associated with human cancers have been identified. However, most of them work thorugh pathways and in a similar way to the BRAF-E. With this in mind, other BRAF mutations than E should also respond

However, Yervoy is a toxic drug and the decision to use it again is not a trivial one. It is , unfortunately, not known whether retreatment is beneficial. There is a study looking at

Melanoma after treatment needs to be followed either by doctor exams, imaging or both.
