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…

Novel inhibitors in development for hepatocellular carcinoma

2010

The multikinase inhibitor sorafenib was the first agent to demonstrate a survival benefit for patients with locally advanced or metastatic hepatocellular carcinoma (HCC). Although sorafenib represents a landmark in the treatment of HCC and proved molecularly targeted therapy to be effective in this disease, it represents just the first step towards an improvement in systemic therapy. Since then, novel inhibitors have been evaluated in early clinical trials, showing potential activity.This article aims to review novel inhibitors emerging in the field of advanced HCC. An Internet-based search was performed to identify abstracts, clinical trials ( www.clinicaltrials.gov , last accessed 30 Nove…

Targeted Therapies in Hepatocellular Carcinoma

2014

Abstract: The onset of hepatocellular carcinoma (HCC) is related to the development of non-neoplastic liver disease, such as viral infections and cirrhosis. Even though patients with chronic liver diseases undergo clinical surveillance for early diagnosis of HCC, this cancer is often diagnosed in advanced stage. In this case locoregional treatment is not possible and systemic therapies are the best way to control it. Until now sorafenib, a Raf and multi-kinase inhibitor has been the best, choice to treat HCC systemically. It showed a survival benefit in multicenter phase III trials. However the proper patient setting to treat is not well defined, since the results in Child-Pugh B patients a…

International and multicenter real‐world study of sorafenib‐treated patients with hepatocellular carcinoma under dialysis

2020

Background & Aims: Information on safety and efficacy of systemic treatment in patients with hepatocellular carcinoma (HCC) under dialysis are limited due to patient exclusion from clinical trials. Thus, we aimed to evaluate the rate, prevalence, tolerability, and outcome of sorafenib in this population. Methods: We report a multicenter study comprising patients from Latin America and Europe. Patients treated with sorafenib were enrolled; demographics, dose modifications, adverse events (AEs), treatment duration, and outcome of patients undergoing dialysis were recorded. Results: As of March 2018, 6156 HCC patients were treated in 44 centres and 22 patients were concomitantly under dial…

Expression and inducibility of drug-metabolizing enzymes in preneoplastic and neoplastic lesions of rat liver during nitrosamine-induced hepatocarcin…

1987

The expression, inducibility, and regulation of four different cytochrome (cyt.) P-450 isoenzymes (PB1, PB2, MC1, and MC2) NADPH-cytochrome P-450 reductase, the glutathione transferases (GSTs) B and C and microsomal epoxide hydrolase (mEHb) have been studied during nitrosamine-induced hepatocarcinogenesis using immunohistochemical techniques. The investigations revealed basic differences in the expression of the individual drug metabolizing enzymes in the course of neoplastic development. While the two GSTs and mEHb were increased in all preneoplastic and benign neoplastic lesions, the levels of the distinct cyt. P-450 isoenzymes were characteristically different from each other. Following …

Hepatocellular carcinoma in a patient with hereditary hemochromatosis and noncirrhotic liver. A case report.

1999

A case of a 62-year-old patient with hereditary hemochromatosis is reported, who developed hepatocellular carcinoma (HCC) in the absence of cirrhosis and other potential risk factors for HCC. Occurrence of HCC in patients with genetic hemochromatosis and noncirrhotic liver is a rare event which has previously been described only six times and appears to be limited to male patients.

Posttransplant Management of Recipients Undergoing Liver Transplantation for Hepatocellular Carcinoma. Working Group Report From the ILTS Transplant …

2020

Although liver transplantation (LT) is the best treatment for patients with localized hepatocellular carcinoma (HCC), recurrence occurs in 6%-18% of patients. Several factors, particularly morphological criteria combined with dynamic parameters, known before LT modify this risk and combined in prediction models may be used to stratify patients at need of variable surveillance strategies. Additional variables though likely explain differences in recurrence rates in patients with the same pre-LT HCC status. One of these variables is possibly immunosuppression (IS). Once recurrence takes place, management is highly heterogenous. Within the International Liver Transplantation Society Consensus …

Local and Regional Therapies for Hepatocellular Carcinoma.

Cryotherapy for liver tumors: current status, perspectives, clinical results, and review of literature.

2004

Cryotherapy has gained importance as a locally ablative treatment option for patients with non-resectable liver tumors, especially metastases from colorectal cancer. We have used this technique since 1996 for the treatment of 77 patients with malignant liver tumors. Patient data was prospectively recorded and follow-up was until September 2002 or death. Fifty-five patients had colorectal cancer liver metastases, 16 metastases from other primaries and 6 had hepatoma. Forty patients had cryotherapy only and 37 had an additional liver resection. Morbidity and mortality were 22% and 1.3%, respectively. In 68% of patients with colorectal liver metastases and an elevated serum carcinoembryonic a…
