Does chemotherapy prevent HCV-related hepatocellular carcinoma? Cons.

2010

The accuracy and the reliability of well-recognized clinical, virologic, histologic, and molecular risk factors for hepatocellular carcinoma (HCC) are still insufficient. Thus, accurate risk prediction of cancer development in individual patients with the aim of selecting high risk cohorts of patients for HCC chemoprevention programs remains an elusive goal. Future directions in chemoprevention of HCC will be in the development of molecular risk models and of new chemopreventive agents. Studies examining multiple genes and proteins (genomics and proteomics) in the same HCCs will be required to evaluate this possibility thoroughly. A strategy aiming at preventing chronic liver disease of any…

Epidemiology, Diagnosis, and Non-Pharmacological Treatment of HCC

2015

ABSTRACT: Hepatocellular carcinoma (HCC) is still one of the most common tumors, ranking first among all cancers in relation to its frequency and mortality. Only very recently has there been a deceleration in the incidence and mortality of this neoplasia, which suggests that we may be close to the peak of the HCC epidemic, at least in the Western population. Risk factors are well known, and the hepatitis B and hepatitis C viruses are the main etiologic factors. Indeed, liver cirrhosis (LC) of any etiology is the main cause of predisposition to the neoplastic degeneration of the liver; an underlying LC is present in most cases of HCC. For this reason, a surveillance program has been establis…

Systemic Therapies in Hepatocellular Carcinoma

2009

Hepatocellular carcinoma (HCC) is one of the most common and lethal malignant tumors worldwide in the human population. Due to late diagnosis and/or advanced underlying liver cirrhosis, only limited treatment options with marginal clinical benefit are available in up to 70% of patients. During the last decades, no effective conventional cytotoxic systemic therapy was available contributing to the dismal prognosis in patients with advanced disease. However, a better knowledge of molecular hepatocarcinogenesis provides today the opportunity for targeted therapy. Positive data from the pivotal phase III SHARP trial assessing the efficacy and safety of the multikinase inhibitor sorafenib broade…

STRATEGIE DI DIREZIONAMENTO ALL’EPATOCARCINOMA DI FARMACI ANTITUMORALI MEDIANTE SISTEMI NANOPARTICELLARI E DI VISUALIZZAZIONE IN CELLULE TUMORALI DEL…

Lo scopo di questo lavoro di tesi è stato quello di realizzare nuovi sistemi nanoparticellari per il direzionamento di farmaci o di agenti per l’imaging, potenzialmente utilizzabili per la terapia e/o per la diagnosi dell’epatocarcinoma (HCC), in particolare per quelle forme caratterizzate dall’overespressione del recettore di membrana degli epatociti ASGP-R o del recettore mitocondriale TSPO. In particolare, nel capitolo 2 sono state descritte la sintesi, la caratterizzazione chimico fisica, la capacità di internalizzazione cellulare e l’efficacia antitumorale di un nuovo sistema nanoparticellare, costituito da un dendrimero a struttura poli-amido-aminica (PAMAM) di quarta generazione, opp…

Hepatocellular carcinoma after thorotrast exposure: establishment of a new cell line (Mz-Hep-1).

1985

A human hepatoma cell line, associated with thorotrast exposure, from an hepatitis B marker-negative patient was established as a permanent cell line (Mz-Hep-1) in tissue culture. Histology of the primary tumor, as well as phase contrast, transmission and scanning electron microscopy of the cultured cells showed typical characteristics of liver cells. Mz-Hep-1 cells secreted complement components (C2, C3, C4), carcinoembryonic antigen, lactate dehydrogenase, chymotrypsin, haptoglobin and retinol-binding protein and expressed HLA-, transferrin-, blood group B-related determinants and complement component C5 and carcinoembryonic antigen on their cell surface. Mz-Hep-1 cells represent the firs…

Hepatocellular Carcinoma and Non-Alcoholic Fatty Liver Disease: From a Clinical to a Molecular Association

2009

Hepatocellular carcinoma (HCC) is the most frequent primary neoplasm of the liver, and is the fourth most common malignancy worldwide. It is also the third leading cause of cancer-related deaths. Most cases of HCC develop on a pre-existing chronic liver disease, usually due to hepatitis C virus (HCV), hepatitis B virus (HBV), or alcohol. However, between 15% and 50% of HCC develops in the absence of a known etiology of liver disease, and different lines of evidence identify in non-alcoholic fatty liver disease (NAFLD) a possible relevant risk factor for occurrence of HCC. Insulin resistance (IR), steatosis, oxidative stress and imbalances in adipokine/cytokine interplay, the most important …
