RESUMO
BACKGROUND AND AIM: Several factors, including proangiogenic cytokines, have been reported as predictive markers for the treatment effect of sorafenib in patients with hepatocellular carcinoma (HCC); however, most of them were determined based on one-time measurements before treatment. METHODS: We consecutively recruited 80 advanced HCC patients who were treated with sorafenib prospectively. Serum levels of eight proangiogenic cytokines and the appearance of adverse events were monitored periodically, and their correlations with the prognoses of the patients were evaluated. RESULTS: Among six significant risk factors for overall survival in univariate analyses, high angiopoietin-2 (hazard ratio, 2.06), high hepatocyte growth factor (hazard ratio, 2.08), and poor performance status before the treatment (hazard ratio, 2.48) were determined as independent risk factors. In addition, high angiopoietin-2 at the time of progressive disease was a marker of short post-progression survival (hazard ratio, 4.27). However, there was no significant variable that predicted short progression-free survival except the presence of hepatitis B virus surface antigen. CONCLUSIONS: Predictions of overall survival and post-progression survival were possible by periodically measuring serum proangiogenic cytokines, especially angiopoietin-2, in patients with HCC treated with sorafenib.

BACKGROUND: Radiofrequency ablation (RFA) is a standard therapy for the treatment of hepatocellular carcinoma (HCC) with 3 or fewer tumors of up to 3 cm (early-stage HCC); when RFA is unsuccessful or unfeasible, transcatheter arterial chemoembolization (TACE) has often been performed. However, little information about the outcome of TACE for early-stage HCC has been reported and it is hard to decide whether to perform additional treatment following TACE in these difficult conditions. The aim of this study was to determine the risk factors for local or intrahepatic distant recurrence after TACE in early-stage HCC. METHODS: Among 1,560 newly diagnosed HCC patients who were admitted to Okayama University Hospital, 43 patients with early-stage HCC who received only TACE in at least one nodule were enrolled in this study. We analyzed the risk factors for local and distant recurrence by the Cox proportional hazard model. RESULTS: The local recurrence rates and intrahepatic distant recurrence rates at 3 months, 6 months, and 1 year were 18.6, 33.4, and 61.8%, and 2.8, 2.8, and 34.3%, [corrected] respectively.Among 12 parameters examined as possible risk factors for recurrence, heterogeneous Lipiodol uptake (risk ratio 3.38; 95% confidence interval 1.14-10.60) and high serum des-gamma-carboxy prothrombin (DCP) (2.58; 1.03-7.14) were significantly correlated with local recurrence, and the presence of multiple tumors (10.64; 1.76-93.75) was significantly correlated with intrahepatic distant recurrence. CONCLUSIONS: Heterogeneous Lipiodol uptake, high serum DCP, and multiple tumors are risk factors for recurrence in patients with early-stage HCC who have undergone palliative TACE.

BACKGROUND AND AIM: Sorafenib, the first agent demonstrated to have efficacy to improve the survival of patients with advanced hepatocellular carcinoma (HCC), is an active multikinase inhibitor affecting angiogenesis and tumor proliferation. We analyzed cytokines related to angiogenesis or cell proliferation, and tried to determine their utility as biomarkers of sorafenib treatment effect for HCC. METHODS: Nine serum cytokines (angiopoietin-2 [Ang-2], follistatin, granulocyte colony-stimulating factor [G-CSF], hepatocyte growth factor [HGF], interleukin-8 [IL-8], leptin, platelet-derived growth factor-BB, platelet endothelial cell adhesion molecule-1, and vascular endothelial growth factor) were measured in 30 HCC patients treated with sorafenib, and the effects of treatment were compared using modified Response Evaluation Criteria in Solid Tumors. RESULTS: All but IL-8 were significantly higher at baseline in patients with progressive disease. Progression-free survival was significantly shorter in patients with high levels of Ang-2, G-CSF, HGF, and leptin, and the hazard ratios were 2.51, 6.89, 2.55, and 4.14, respectively. As the number of cytokines at a high level increased, the treatment response deteriorated. Disease progression was seen in three of 12 (25.0%) patients with zero to two high biomarkers, two of six (33.3%) patients with 3-5 high biomarkers, and 10 of 12 (83.3%) patients with six to eight high biomarkers (P=0.008). The prognosis of all patients with eight high biomarkers was progressive disease. CONCLUSION: High levels of serum cytokines at baseline were correlated with poor effects of sorafenib treatment in patients with HCC.
