SnapShot: Hepatocellular carcinoma.
2014
Hepatocellular carcinoma is the sixth most common cancer globally and the second most lethal cancer worldwide. This SnapShot depicts the molecular and morphological features of this heterogeneous disease, as well as outlines associated prognostic factors, current and emerging therapies, and challenges ahead.
Dexamethasone desensitizes hepatocellular and colorectal tumours toward cytotoxic therapy
2005
The glucocorticoid dexamethasone is frequently used as co-treatment in cytotoxic cancer therapy, e.g. to prevent nausea, to protect normal tissue or for other reasons. While the potent pro-apoptotic properties and the supportive effects of glucocorticoids to tumour therapy in lymphoid cells are well studied, the impact to cytotoxic treatment of colorectal and hepatocellular carcinoma is unknown. We tested apoptosis-induction, viability, tumour growth and protein expression using 8 established cell lines, 18 surgical specimen and a xenograft on nude mice. In the presence of dexamethasone we found strong inhibition of apoptosis in response to 5-FU, cisplatin, gemcitabine or gamma-irradiation,…
Prognostic Relevance of Objective Response According to EASL Criteria and mRECIST Criteria in Hepatocellular Carcinoma Patients Treated with Loco-Reg…
2015
Background The European Association for the Study of the Liver (EASL) criteria and the modified Response Evaluation Criteria in Solid Tumors (mRECIST) are currently adopted to evaluate radiological response in patients affected by HCC and treated with loco-regional procedures. Several studies explored the validity of these measurements in predicting survival but definitive data are still lacking. Aim To conduct a systematic review of studies exploring mRECIST and EASL criteria usefulness in predictive radiological response in HCC undergoing loco-regional therapies and their validity in predicting survival. Methods A comprehensive search of the literature was performed in electronic database…
The burden of hepatocellular carcinoma in non-alcoholic fatty liver disease: Screening issue and future perspectives
2019
In recent decades, non-alcoholic fatty liver disease (NAFLD) has become the most common liver disease in the Western world, and the occurrence of its complications, such as hepatocellular carcinoma (HCC), has rapidly increased. Obesity and diabetes are considered not only the main triggers for the development of the disease, but also two independent risk factors for HCC. Single nucleotide polymorphisms (such as PNPLA3, TM6SF2 and MBOAT7) are related to the susceptibility to the development of HCC and its progression. Therefore, an appropriate follow-up of these patients is needed for the early diagnosis and treatment of HCC. To date, international guidelines recommend the use of ultrasonogr…
Ten years of sorafenib in hepatocellular carcinoma: Are there any predictive and/or prognostic markers?
2018
Sorafenib has been considered the standard of care for patients with advanced unresectable hepatocellular carcinoma (HCC) since 2007 and numerous studies have investigated the role of markers involved in the angiogenesis process at both the expression and genetic level and clinical aspect. What results have ten years of research produced? Several clinical and biological markers are associated with prognosis. The most interesting clinical parameters are adverse events, Barcelona Clinic Liver Cancer stage, and macroscopic vascular invasion, while several single nucleotide polymorphisms and plasma angiopoietin-2 levels represent the most promising biological biomarkers. A recent pooled analysi…
Recurrence of hepatocellular carcinoma after direct acting antiviral treatment for hepatitis C virus infection: Literature review and risk analysis
2018
Although studies suggest decreased incident hepatocellular carcinoma (HCC) after treatment with direct-acting antivirals (DAAs) for hepatitis C virus (HCV) infection, data are conflicting regarding risk and aggressiveness of recurrence in patients who have a history of treated HCC. This review analyses data available in literature in order to elucidate the impact of DAAs on the risk of HCC recurrence after successful treatment of the tumor. Overall 24 papers were identified. The available data cannot be considered definitive, but the initial alarmist data indicating an increased risk of recurrence have not been confirmed by most subsequent studies. The suggested aggressive pattern (rapid gr…
Cetuximab plus FOLFOX-4 in untreated patients with advanced colorectal cancer: a Gruppo Oncologico dell'Italia Meridionale Multicenter phase II study.
2010
<i>Objectives:</i> FOLFOX-4 and FOLFIRI are considered equivalent in terms of activity and efficacy as first-line chemotherapy in metastatic colorectal cancer (mCRC). The monoclonal antibody (mAb) cetuximab showed intrinsic activity as a single agent in mCRC and was approved in combination with CPT-11 for patients who failed previous CPT-11-based treatment. The purpose of this phase II study was to evaluate the activity and safety of FOLFOX-4 plus cetuximab in untreated mCRC patients. <i>Methods:</i> Untreated patients with measurable metastatic disease and expressing epidermal growth factor receptor (EGFR) received cetuximab at a loading dose of 400 mg/m<sup>2…
The evolutionary scenario of hepatocellular carcinoma in Italy: an update
2017
Background and aims Epidemiology of hepatocellular carcinoma is changing worldwide. This study aimed at evaluating the changing scenario of etiology, presentation, management and prognosis of hepatocellular carcinoma in Italy during the last 15 years. Methods Retrospective analysis of the ITA.LI.CA (Italian Liver Cancer) database including 5192 hepatocellular carcinoma patients managed in 24 centers from 2000 to 2014. Patients were divided into three groups according to the date of cancer diagnosis (2000-2004, 2005-2009 and 2010-2014). Results The main results were: 1) progressive patient aging; 2) progressive expansion of non-viral cases and, namely, of “metabolic” hepatocellular carcinoma…
Cetuximab rechallenge in metastatic colorectal cancer patients: how to come away from acquired resistance?
2012
Background: Scientific data provide the evidence that secondary K-RAS mutations do not occur during anti-epidermal growth factor receptor therapy in colorectal cancer patients. This multicenter phase II prospective study aims to investigate the activity of a retreatment with a cetuximab-based therapy. Patients and methods: We enrolled 39 irinotecan-refractory patients who had a clinical benefit after a line of cetuximab- plus irinotecan-based therapy and then a progression of disease for which underwent a new line chemotherapy and finally, after a clear new progression of disease, were retreated with the same cetuximab- plus irinotecan-based therapy. Results: Median number of therapeutic li…
Comparison of prognostic models in advanced hepatocellular carcinoma patients undergoing Sorafenib: A multicenter study
2021
Background: Sorafenib is the gold standard therapy for the advanced hepatocellular carcinoma (HCC). No scoring/staging is universally accepted to predict the survival of these patients. Aims: To evaluate the accuracy of the available prognostic models for HCC to predict the survival of advanced HCC patients treated with Sorafenib included in the Italian Liver Cancer (ITA.LI.CA.) multicenter cohort. Methods: The performance of several prognostic scores was assessed through a Cox regression-model evaluating the C-index and the Akaike Information Criterion (AIC). Results: Data of 1129 patients were analyzed. The mean age of patients was 61.6 years, and 80.8% were male. During a median follow-u…
