BACKGROUND Activin receptor-like kinase 1 (ALK1) is a Transforming Growth Factor-beta (TGF-beta) receptor type I, mainly expressed in endothelial cells that plays a pivotal role in vascular remodelling and angiogenesis. Mutations in the ALK1 gene (ACVRL1) give rise to Hereditary Haemorrhagic Telangiectasia, a dominant autosomal vascular dysplasia caused by(More)
BACKGROUND Cetuximab-induced hypomagnesemia has been associated with improved clinical outcomes in advanced colorectal cancer (CRC). We explored this relationship from a randomized clinical trial of cetuximab plus best supportive care (BSC) versus BSC alone in patients with pretreated advanced CRC. PATIENTS AND METHODS Day 28 hypomagnesemia grade (0(More)
Purpose: Cetuximab improves survival in patients with K-ras wild-type advanced colorectal cancer. We examined the predictive and prognostic significance of additional biomarkers in this setting, in particular BRAF, PIK3CA, and PTEN. Experimental Design: Available colorectal tumor samples were analyzed from the CO.17 study. BRAF mutations were identified in(More)
