Mutations of the KRAS oncogene are predictive for resistance to treatment with antibodies against the epithelial growth factor receptor in patients with colorectal cancer. Overcoming this therapeutic dilemma could potentially be achieved by the introduction of drugs that inhibit signaling pathways that are activated by KRAS mutations. To comprehensively identify such signaling pathways we profiled pretreatment biopsies from 65 patients with locally advanced rectal cancer – 30 of which carried mu...
