Impact of Individual Components of the Metabolic Syndrome on the Outcome of Patients with Advanced Hepatocellular Carcinoma Treated with Sorafenib
2017
<b><i>Background/Aim:</i></b> Individual components of the metabolic syndrome (MS) such as obesity or diabetes mellitus impair the prognosis of patients with hepatocellular carcinoma (HCC) following curative treatment approaches or transarterial therapies. The aim of this retrospective study was to assess the impact of these factors on the overall survival (OS) of patients with advanced HCC treated with sorafenib. <b><i>Methods:</i></b> Univariate and multivariate analyses were performed to assess the impact of individual components of the MS on the OS of 152 consecutive patients with advanced HCC treated with sorafenib. <b><i>Resu…
Refining sorafenib therapy: lessons from clinical practice
2015
ABSTRACT Understanding the best use of sorafenib is essential in order to maximize clinical benefit in hepatocellular carcinoma. Based on Phase III and noninterventional study data, as well as our extensive experience, we discuss dose modification in order to manage adverse events, disease response evaluation and how to maximize treatment benefit. Sorafenib should be initiated at the approved dose (400 mg twice daily) and reduced/interrupted as appropriate in order to manage adverse events. Dose modification should be considered before discontinuation. Appropriate tumor response assessment is critical. Focusing on radiologic response may result in premature sorafenib discontinuation; symp…
Systemic therapies for hepatocellular carcinoma: The present and the future
2021
Hepatocellular carcinoma is diagnosed in more than half of all cases at unresectable stage when no potentially curative treatments are feasible. Since 2008, sorafenib had represented the only effective first line systemic therapy over the last decade until the approval of lenvatinib, who showed to be non-inferior to sorafenib. Recently, for the first time, a combination of immunotherapy and antiangiogenic drug, atezolizumab plus bevacizumab, was associated with a significantly longer overall survival and progression free survival compared to sorafenib, becoming the new best performing first-line approach for unresectable HCC. After several randomized controlled trials (RCTs) that have attem…
Preclinical and clinical evidence of activity of pazopanib in solitary fibrous tumour
2014
Abstract Background To explore the activity of pazopanib in solitary fibrous tumour (SFT). Patients and methods In a preclinical study, we compared the activity of pazopanib, sorafenib, sunitinib, regorafenib, axitinib and bevacizumab in a dedifferentiated-SFT (DSFT) xenotransplanted into Severe Combined Immunodeficiency (SCID) mice. Antiangiogenics were administered at their reported optimal doses when mean tumour volume (TV) was 80 mm3. Drug activity was assessed as TV inhibition percentage (TVI%). From May 2012, six consecutive patients with advanced SFT received pazopanib, on a national name-based programme. In one case sunitinib was administered after pazopanib failure. Results In the …
A Nomogram-Based Prognostic Model for Advanced Hepatocellular Carcinoma Patients Treated with Sorafenib: A Multicenter Study
2021
Simple Summary Accurate prognostic systems capable of predicting the survival of patients with advanced hepatocellular carcinoma undergoing Sorafenib therapy are still lacking. The search for the ideal predictive tool for survival and drug response is justified by the recent availability of several other drugs effective for these patients, licensed as first- and second-line treatment, other than reducing adverse events and costs. In this study, we aimed to identify simple demographic and clinical parameters able to predict survival and Sorafenib response in a large multicenter cohort. In this study, we showed that patient’s general status, liver function and damage laboratory parameters and…
Core-Shell Arginine-Containing Chitosan Microparticles for Enhanced Transcorneal Permeation of Drugs
2019
Chitosan oligosaccharide (C) was functionalized with L-arginine (A) and short hydrocarbon chains (C-8) to design an amphiphilic copolymer, henceforth CAC(8), leading to microparticles (MPs) consisting of an arginine-decorated hydrophilic shell and inner hydrophobic domains allowing the encapsulation of high amount hydrophobic drugs such as sorafenib tosylate (>10% w/w). L-arginine side chains were selected in order to impart the final MPs enhanced transcorneal penetration properties, thus overcoming the typical biological barriers which hamper the absorption of drugs upon topical ocular administration. The mucoadhesive properties and drug release profile of the CAC(8) MPs (CAC(8)-MPs) were …
Targeted Therapies in Hepatocellular Carcinoma
2015
Hepatocellular carcinoma (HCC) is one of the main causes of death in patients affected by chronic liver diseases. The awareness of the biomolecular mechanisms underlying the complex carcinogenic process led to the development of targeted molecules, which are able to block this process. Sorafenib is a tyrosine-kinase inhibitor, and currently, it is the only drug approved by the US Food and Drug Administration (FDA) for the treatment of HCC. However, some studies have demonstrated the efficacy of single drug therapies or combination therapies. They showed an improvement with regard to overall survival, time to progression, and progression-free survival, although these therapies were not free …
Synthesis and characterization of PEGylated graphene oxide for sorafenib modified release
2015
Concept Graphene, a single layer of sp2-hybridized carbon atoms arranged in a honeycomb two-dimensional (2-D) crystal lattice, has evoked enormous interest throughout the scientific community since its first appearance in 2004. Due to its unique structure and geometry, graphene possesses remarkable physical-chemical properties (including large specific surface area and biocompatibility) that enable it to be an ideal material for several applications, ranging from quantum physics, nanoelectronics, energy research, catalysis and engineering of nanocomposites and biomaterials. In the area of nanomedicine, graphene and its derivatives can be exploited for a broad range of applications, includin…
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 …
