Core Tip

Core tip: There is an urgent clinical need to prediction of sorafenib response and prognosis in patients with hepatocellular carcinoma (HCC) receiving sorafenib treatment due to the potentially serious side effects of sorafenib in these patients. Multivariate analysis showed that the von Willebrand factor (VWF) antigen (VWF:Ag)/a disintegrin-like and metalloproteinase with thrombospondin type-1 motifs 13 (ADAMTS13) activity (ADAMTS13:AC) ratio was the only predictive factor for sorafenib response and ADAMTS13:AC was the only prognostic factor in patients with HCC receiving sorafenib treatment. The VWF:Ag/ADAMTS13:AC ratio and ADAMTS13:AC are potentially useful biomarkers for sorafenib response and prognosis, respectively, in patients with HCC receiving sorafenib treatment.
