PRESENTAZIONE ECOGRAFICA DELL’EPATOCARCINOMA: ESPERIENZA DI UN SINGOLO CENTRO NELL’ARCO DI TRE DECENNI

2019

Valutare i cambiamenti della presentazione ecografica (US) degli epatocarcinomi (HCC) diagnosticati presso la nostra UO di Medicina Interna in tre periodi:1993-98, 2003-2008,2013-18. Il Gruppo 1 (G1) (1993-1998) comprendeva 174 HCC, il Gruppo 2 (G2) (2003-08) 96, il Gruppo 3 (G3) (2013-2018) 102. Sono stati registrati età, sesso, markers HBV, HCV, uso di alcol, alfafetoproteina (AFP), test di funzionalità epatica, autoanticorpi, ferritinemia. La diagnosi di HCC in G2 e G3 è stata posta secondo le linee guida EASL, in G1 con istologia o citologia nel 40%, nel resto con multiple tecniche di imaging concordanti (ecografia, TC, TC con lipiodol, angiografia), livelli sierici di AFP>200 ng/ml.…

Outcome of liver cancer patients with SARS‐CoV‐2 infection: an international, multicentre, cohort study

2022

Background & Aims Information about the impact of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in patients with liver cancer is lacking. This study characterizes the outcomes and mortality risk in this population. Methods Multicentre retrospective, cross-sectional, international study of liver cancer patients with SARS-CoV-2 infection registered between February and December 2020. Clinical data at SARS-CoV-2 diagnosis and outcomes were registered. Results Two hundred fifty patients from 38 centres were included, 218 with hepatocellular carcinoma (HCC) and 32 with intrahepatic cholangiocarcinoma (iCCA). The median age was 66.5 and 64.5 years, and 84.9% and 21.9% had cirrhosis…

HALT-C in the final analysis: A molehill out of a mountain

2009

Prolonged therapy of advanced chronic hepatitis C with low-dose peginterferon. Di Bisceglie AM, Shiffman ML, Everson GT, Lindsay KL, Everhart JE, Wright EC, Lee WM, Lok AS, Bonkovsky HL, Morgan TR, Ghany MG, Morishima C, Snow KK, Dienstag JL, HALT-C Trial Investigators. Background In patients with chronic hepatitis C who do not have a response to antiviral treatment, the disease may progress to cirrhosis, liver failure, hepatocellular carcinoma, and death. Whether long-term antiviral therapy can prevent progressive liver disease in such patients remains uncertain. Methods We conducted a randomized, controlled trial of peginterferon alfa-2a at a dosage of 90μg per week for 3.5 years, as comp…

Antitumor activity of the novel small molecule Akt inhibitor SC66 in hepatocellular carcinoma cells.

2013

Hepatocellular carcinoma (HCC) is the fifth most common cancer worldwide characterized by poor and often limited or no response to current drug therapies. The PI3K/Akt/mTOR pathway is a key regulator of cell proliferation and survival. Alterations in this pathway have been reported in many types of human cancer, including HCC. It has become evident that Akt inhibitors have great potential in cancer treatment. SC66 is a new allosteric Akt inhibitor that facilitates ubiquitination of Akt, favoring its degradation via the proteasome, thus inhibiting Akt signaling. In the present study, we investigated the anticancer activity of SC66 in HCC cell lines (HepG2, Huh7, Hep3B, PLC/PRF/5 and HA22T/VG…

The Evolving Scenario in the Assessment of Radiological Response for Hepatocellular Carcinoma in the Era of Immunotherapy: Strengths and Weaknesses o…

2022

Hepatocellular carcinoma (HCC) is a challenging malignancy characterised by clinical and biological heterogeneity, independent of the stage. Despite the application of surveillance programs, a substantial proportion of patients are diagnosed at advanced stages when curative treatments are no longer available. The landscape of systemic therapies has been rapidly growing over the last decade, and the advent of immune-checkpoint inhibitors (ICIs) has changed the paradigm of systemic treatments. The coexistence of the tumour with underlying cirrhosis exposes patients with HCC to competing events related to tumour progression and/or hepatic decompensation. Therefore, it is relevant to adopt prop…

Targeted delivery of siRNAs against hepatocellular carcinoma-related genes by a galactosylated polyaspartamide copolymer

2021

Given the lack of effective treatments for Hepatocellular carcinoma (HCC), the development of novel therapeutic approaches is very urgent. Here, siRNAs were delivered to HCC cells by a synthetic polymer containing α,β-poly-(N-2-hydroxyethyl)-D,L-aspartamide-(PHEA) derivatized with diethylene triamine (DETA) and bearing in the side chain galactose (GAL) linked via a polyethylene glycol (PEG) to obtain (PHEA-DETA-PEG-GAL, PDPG). The GAL residue allows the targeting to the asialo-glycoprotein receptor (ASGPR), overexpressed in HCC cells compared to normal hepatocytes. Uptake studies performed using a model siRNA or a siRNA targeted against the enhanced green fluorescence protein, demonstrated …

Sunitinib in patients with advanced hepatocellular carcinoma after progression under sorafenib treatment.

2010

<i>Objective:</i> To evaluate the safety and efficacy of sunitinib in patients with advanced hepatocellular carcinoma (HCC) after progression under sorafenib treatment. <i>Methods:</i> Sunitinib was administered at 37.5 mg daily (4-weeks-on/2-weeks-off schedule) after progression under sorafenib treatment. Adverse events (AEs) were assessed using NCI-CTCAE v3.0, and tumor response was evaluated according to RECIST. Data were analyzed retrospectively. <i>Results:</i> Eleven patients with metastatic disease were treated. Seven patients (64%) presented with no liver cirrhosis, including 3 patients with a history of liver transplantation. The first radiologic…

The NUPR1/p73 axis contributes to sorafenib resistance in hepatocellular carcinoma

2021

The multikinase inhibitor sorafenib was the first drug approved by the FDA for treating patients with advanced hepatocellular carcinoma (HCC). However, sorafenib resistance remains a major challenge for improving the effectiveness of HCC treatment. Previously, we identified several genes modulated after sorafenib treatment of human HCC cells, including the stress-inducible nuclear protein 1 (NUPR1) gene. Multiple studies have shown that NUPR1 regulates autophagy, apoptosis, and chemoresistance. Here, we demonstrate that treatment of HCC cells with sorafenib resulted in the activation of autophagic flux. NUPR1 knock-down (KD) in HCC cells was associated with increased p62 expression, suggest…
