A biomarker of response to therapy in metastatic BRAFV600E colorectal cancers

Colorectal cancers expressing the mutant BRAFV600E comprise 10% of all metastatic colorectal cancers, present with a poor prognosis, and are refractory to common therapies. We discovered that a subgroup of these tumors that carries loss-of-function RNF43 mutations is associated with significantly improved response to the current standard-of-care anti-BRAF–anti-EGFR combination therapy.
