The calm before the storm: a report from the International Liver Cancer Association Congress 2015 – part 2
2016
International Liver Cancer Association Congress 2015, Paris, France, 4–6 September 2015 Since its creation 9 years ago, in 2007, the International Liver Cancer Association has focused on the multidisciplinary approach to liver cancer due to advances in hepatology science and care worldwide. In its 2015 annual conference, held on 4–6 September in Paris, France, the most recent progresses in the basic biology, management and treatment of liver cancer have been presented. This report, divided into two parts, introduces and critically reviews some of the most intriguing topics discussed at the meeting.
Sorafenib in advanced hepatocellular carcinoma
2008
none 25 BACKGROUND: No effective systemic therapy exists for patients with advanced hepatocellular carcinoma. A preliminary study suggested that sorafenib, an oral multikinase inhibitor of the vascular endothelial growth factor receptor, the platelet-derived growth factor receptor, and Raf may be effective in hepatocellular carcinoma. METHODS: In this multicenter, phase 3, double-blind, placebo-controlled trial, we randomly assigned 602 patients with advanced hepatocellular carcinoma who had not received previous systemic treatment to receive either sorafenib (at a dose of 400 mg twice daily) or placebo. Primary outcomes were overall survival and the time to symptomatic progression. Seconda…
Tumor enhancement at contrast-enhanced CT and Gd-enhanced MRI for the assessment of treatment response of hepatocellular carcinoma (HCC) after sorafe…
2012
Scopo: To investigate whether arterial enhancement of advanced HCC during pre-treatment and follow-up contrast-enhanced CT (CECT) or Gd-enhanced MRI (Gd-MRI) can be used to predict tumor response to sorafenib. Materiali e metodi: Seventeen patients (12M, 5F; mean age: 69 years) receiving sorafenib for inoperable HCC between 2007 and 2010 were included. Median interval time between pre-treatment and follow-up CECT or Gd-MRI was 160 days. Tumor arterial enhancement was measured at baseline and follow-up: (tumor attenuation/intensity on arterial phase – tumor attenuation/intensity on unenh! anced images)/(tumor attenuation/intensity on unenhanced images) x 100. Response was assessed according …
Sorafenib: from literature to clinical practice
2013
Sorafenib is considered the standard systemic therapy for hepatocellular carcinoma (HCC), in patients with well-preserved liver function (Child-Pugh A class) and advanced-stage HCC (BCLC-C) or in patients with HCC progressing after locoregional therapies, with a high grade of recommendation. The approval of sorafenib for this indication was grounded on the efficacy and the safety results reported by two international randomized, controlled trials, the SHARP and the Asia-Pacific studies. In addition, the efficacy and the safety of sorafenib in clinical practice are addressed by several field-practice experiences, including the multinational GIDEON study and the SOFIA study. Finally, further …
Transarterial chemoembolization and sorafenib in patients with intermediate-stage hepatocellular carcinoma: time to enter routine clinical practice?
2015
According to the guidelines of the European Association for the Study of the Liver (EASL), patients affected from hepatocellular carcinoma (HCC) can be classified according to the Barcelona Clinic Liver Cancer (BCLC) staging system. This classification system divides HCC patients in five stages (0, A, B, C and D) on the basis of a number of prognostic and treatment- related variables such as tumor status and liver function. A specific treat ment approach is then proposed for each of the above-mentioned stages. Transarterial chemoembolization (TACE) is recommended as first-line therapy in the treatment of patients with intermediate-stage (BCLC-B class) HCC [1]. The efficacy of this procedure…
Field-practice study of sorafenib therapy for hepatocellular carcinoma: a prospective multicenter study in Italy
2011
A multicenter randomized controlled trial established sorafenib as a standard of care for patients with advanced hepatocellular carcinoma (HCC). Because the study was prematurely interrupted due to survival benefits in the sorafenib arm, we conducted an observational study to adequately assess risks and benefits of this regimen in field practice. Starting in 2008, all clinically compensated patients with advanced HCC and those with an intermediate HCC who were unfit or failed to respond to ablative therapies were consecutively evaluated in six liver centers in Italy, for tolerability as well as radiologic and survival response to 800-mg/d sorafenib therapy. Treatment was down-dosed or inter…
Atezolizumab plus bevacizumab versus lenvatinib or sorafenib in non-viral unresectable hepatocellular carcinoma: an international propensity score ma…
2022
Background: A growing body of evidence suggests that non-viral hepatocellular carcinoma (HCC) might benefit less from immunotherapy. Materials and methods: We carried out a retrospective analysis of prospectively collected data from consecutive patients with non-viral advanced HCC, treated with atezolizumab plus bevacizumab, lenvatinib, or sorafenib, in 36 centers in 4 countries (Italy, Japan, Republic of Korea, and UK). The primary endpoint was overall survival (OS) with atezolizumab plus bevacizumab versus lenvatinib. Secondary endpoints were progression-free survival (PFS) with atezolizumab plus bevacizumab versus lenvatinib, and OS and PFS with atezolizumab plus bevacizumab versus soraf…
Nanoassemblies Based on Supramolecular Complexes of Nonionic Amphiphilic Cyclodextrin and Sorafenib as Effective Weapons to Kill Human HCC Cells
2015
Sorafenib (Sor), an effective chemiotherapeutic drug utilized against hepatocellular carcinoma (HOC), robustly interacts with nonionic amphiphilic cyclodextrin (aCD, SC6OH), forming, in aqueous solution, supramolecular complexes that behave as building blocks of highly water-dispersible colloidal nanoassemblies. SC6OH/Sor complex has been characterized by complementary spectroscopic techniques, such as UV-vis, steady-state fluorescence and anisotropy, resonance light scattering and H-1 NMR. The spectroscopic evidences and experiments carried out in the presence of an adamantane derivative, which competes with drug for CD cavity, agree with the entrapment of Sor in aCD, pointing out the role…
Lipid nanocarriers containing sorafenib inhibit colonies formation in human hepatocarcinoma cells
2015
Here, the potential of two nanostructured lipid carriers (NLC) for controlled release of sorafenib was evaluated. The obtained systems showed characteristics suitable as drug delivery systems for the treatment of hepatocellular carcinoma (HCC) through parenteral administration. The use of a mixture between a solid lipid (tripalmitin) with a liquid lipid (Captex 355 EP/NF or Miglyol 812) to prepare NLC systems could give a higher drug loading capacity and a longer term stability during storage than that obtained by using only solid lipids. The obtained nanoparticles showed a nanometer size and high negative zeta potential values. Scansion electron microscopy (SEM) of the sorafenib loaded NLC…
Yin Yang 1 and raf-1 Kinase Inhibitory Protein Status in Hepatocellular carcinoma: Future Perspectives
2010
We focus on to the role of the transcription factors NF-κB and Yin Yang 1 (YY1) and of Raf-1 kinase inhibitory protein (RKIP) in hepatocellular carcinoma (HCC). YY1, whose expression is enhanced by NF-κB, favors tumorigenesis. RKIP inhibits the oncogenic activities of MAPK and NF-κB pathways and promotes drug-induced apoptosis. Mutual influences between YY1 and RKIP may exist and there is separate evidence that relevant increases in YY1 and reductions in RKIP occur in HCC. In a recent study on clinical HCC, we found that, indeed, the ratio of YY1 to RKIP mRNA and protein expression is very frequently profoundly inverted in tumors compared with adjacent tissues. Hyperactivation of YY1 in tum…
