A new test for BRAF mutations outshines the standard method, according to results reported at the 2013 International Conference on Molecular Targets and Cancer Therapeutics. There are more than 30 known different versions of BRAF mutations, which occur mostly in melanomas but are also found in other types of cancer. The standard test for BRAF mutations requires a lot of sample preparation and usually takes 3 to 4 weeks. In contrast, the new test—called MDx—skips sample preparation and gives accurate results in as little as 90 minutes. Ultimately, the researchers plan to extend this approach to other cancer mutations with U.S. Food and Drug Administration (FDA)-approved targeted therapies.
