Abstract Hepatocellular carcinoma HCC is a highly vascular tumor through the process of angiogenesis. To evaluate more non-invasive techniques for assessment of blood flow BF in HCC, this study examined the relationships between BF of HCC measured by computer tomography CT perfusion imaging and four circulating angiogenic factors in HCC patients. Interleukin 6 IL-6, interleukin 8 IL-8, vascular endothelial growth factor VEGF, and platelet derived growth factor PDGF in plasma were measured using Bio-Plex multiplex immunoassay in 21 HCC patients and eight healthy controls. Circulating IL-6, IL-8 and VEGF showed higher concentrations in HCC patients than in controls p < 0.05, and predicted HCC occurrence better than chance p < 0.01. Twenty-one patients with HCC received 21-phase liver imaging using a 64-slice CT. Total BF, arterial BF, portal BF, arterial fraction arterial BF-total BF of the HCC and surrounding liver parenchyma, and HCC-parenchyma ratio were measured using a dual-vessel model. After analyzing the correlations between BF in HCC and four circulating angiogenic factors, we found that the HCC-parenchyma ratio of arterial BF showed a significantly positive correlation with the level of circulating IL-8 p < 0.05. This circulating biomarker, IL-8, provides a non-invasive tool for assessment of BF in HCC. View Full-Text
