A rapidly progressive motor neuron disease associated to a natural killer cells leukaemia
2019
une system play a complex role, either protective or toxic, in ALS pathogenesis [1–3]. In particular, compelling evidence indicate that increased blood level of natural killer (NK) and NK-T cells may contribute to the disease development and progression [2,3]. Here, we report on a patient with an aggressive Motor Neuron Disease (MND) associated with NK/NK-T cells leukaemia. 1. Case report A 79-year-old man presented with several months-history of a progressive atrophy and weakness of the upper limbs, which quickly spread to the lower limbs. Onset was subtle and apparently occurred in the month of July (the specific date is not shown for privacy), when the patient noticed a mild weakness in …
Hepatectomy Versus Sorafenib in Advanced Non-Metastatic Hepatocellular Carcinoma: A Real-Life Multicentric Weighted Comparison
2022
Objective: The aim of the study was to compare SURG vs SOR regarding the OS and progression-free survival (PFS) in a real-world clinical scenario. Background data: The treatment for advanced nonmetastatic HCC belonging to the Barcelona Clinic Liver Cancer stage C (BCLC C) is still controversial. Methods: BCLC C patients without extrahepatic spread and tumoral invasion of the main portal trunk were considered. Surgical patients were obtained from the HE.RC.O.LE.S. Register, whereas sorafenib patients were obtained from the ITA.LI.CA register The inverse probability weighting (IPW) method was adopted to balance the confounders between the 2 groups. Results: Between 2008 and 2019, 478 patients…
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…
Transarterial chemoembolization and sorafenib in hepatocellular carcinoma
2014
Transarterial chemoembolization (TACE) is considered as the standard therapy for patients with intermediate-stage hepatocellular carcinoma. However, given the high heterogeneity of this population, no common strategy or protocol standardization has been defined yet. In the last few years TACE treatment has been combined with sorafenib systemic therapy, reporting overall positive results both in terms of safety and efficacy. This systematic review presents and critically discusses the evidence available on the use of TACE in combination (concomitant or sequential) with sorafenib, focusing also on clinical trials currently ongoing to better define an optimal therapeutic strategy for this grou…
Is the efficacy of sorafenib treatment in patients with hepatocellular carcinoma affected by age?
2013
Cancer is a prevalent disease in the elderly population and hepatocellular carcinoma (HCC) is a major health problem among all tumors. Curative treatments for early-stage include liver transplantation, resection and percutaneous ablation. Transarterial chemoembolization (TACE) and sorafenib, classified as non-curative treatments, can improve survival for patients with intermediate and advanced tumors, respectively. Even if the incidence of HCC progressively increases with advanced age in all populations, reaching a peak at 70 years, few reports concerning correct management of HCC in elderly patients exist. Moreover, data from large randomized controlled trials (RCT) poorly reflect the elde…
Heterogeneity of Patients with Intermediate (BCLC B) Hepatocellular Carcinoma: Proposal for a Subclassification to Facilitate Treatment Decisions
2013
The intermediate stage of hepatocellular carcinoma (HCC) comprises a highly heterogeneous patient population and therefore poses unique challenges for therapeutic management, different from the early and advanced stages. Patients classified as having intermediate HCC by the Barcelona Clinic Liver Cancer (BCLC) staging system present with varying tumor burden and liver function. Transarterial chemoembolization (TACE) is currently recommended as the standard of care in this setting, but there is considerable variation in the clinical benefit patients derive from this treatment.In April 2012, a panel of experts convened to discuss unresolved issues surrounding the application of current guidel…
Survival of patients treated with sorafenib for hepatocellular carcinoma recurrence after liver transplantation: A systematic review and meta-analysis
2014
Background: Data on survival and safety of sorafenib for hepatocellular carcinoma recurrence after liver transplant are still equivocal. Aim: We performed a meta-analysis of published studies, with the aim of estimating the 1-year rates of survival, analysing the variability in survival rates and, finally, identifying the factors associated with a longer survival. Methods: Data from 8 of the 17 selected studies were pooled, while the other 9 were excluded because survival rates were missing. All included studies were retrospective. Results: Overall, the 1-year survival ranged from 18% to 90%. Tumour progression was the main cause of death. The second cause was bleeding, reported only in pat…
Extrahepatic spread of hepatocellular carcinoma
2012
Hepatocellular carcinoma (HCC) is a major health problem. The treatment of HCC depends on the tumour stage and on the severity of underlying cirrhosis, however, a majority of HCC patients have advanced disease at presentation. In recent years extra-hepatic spread (ES) of HCC seems to have been observed more frequently than in the past even if few data exist in literature on prevalence, clinical presentation and prognosis of patients with HCC ES. Aim of this brief review is underline the main concerns, pitfalls and warnings in practicing with these patients. ES of HCC are not rare, and the probability of finding ES is higher in patients with advanced intra-hepatic HCC. The more frequent ES s…
Galactosylated polymeric carriers for liver targeting of sorafenib
2014
In this paper, we describe the preparation of liver-targeted polymeric micelles potentially able to carry sorafenib to hepatocytes for treatment of hepatocarcinoma (HCC), exploiting the presence of carbohydrate receptors, ASGPR. These micelles were prepared starting from a galactosylated polylactide-polyaminoacid conjugate. This latter was obtained by chemical reaction of α,β-poly(N-2-hydroxyethyl) (2-aminoethylcarbamate)-d,l-aspartamide (PHEA-EDA) with polylactic acid (PLA), and subsequent reaction with lactose, leading to PHEA-EDA-PLA-GAL copolymer. Liver-targeted sorafenib-loaded micelles were obtained in aqueous media at low PHEA-EDA-PLA-GAL copolymer concentration value with nanometer …
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…
