Predicting survival in patients with hepatocellular carcinoma treated by transarterial chemoembolisation

Background Transarterial chemoembolisation (TACE) is first-line treatment in unresectable hepatocellular carcinoma (HCC) and rescue treatment after failure of radical treatments in early stage HCC. Prognostic tools for HCC using time-fixed Cox models may be unreliable in patients treated with TACE because time-varying predictors interact. Aim To explore time-dependent variables as survival predictors in patients with HCC receiving TACE as first-line or second-line treatment. Methods Eighty four consecutive patients with HCC (mean age 68; male gender 62%; Child-Pugh class: A n = 73, B n = 11; Barcelona Clinic Liver Cancer class: A n = 44, B n = 24, C n = 16) treated with TACE were enrolled. …

Assessment of treatment response in hepatocellular carcinoma: a review of the literature

Hepatocellular carcinoma (HCC) has a high incidence all over the world. Even if the primary end point of treatment of HCC is survival, radiological response could be a surrogate end point of survival, and could have a key role in clinical management. Since 1950 several radiological response criteria have been applied; however, it was not until 2000 that specific criteria for HCC were introduced by the European Association for the Study of the Liver (EASL), and these were then standardized in 2010 with the development of the modified Response Evaluation Criteria for Solid Tumors (mRECIST) for HCC. The purpose of this brief review is to compare data in literature regarding the application an…

Causes of and prevention strategies for hepatocellular carcinoma.

Hepatocellular carcinoma (HCC) is a challenging malignancy of global importance. It is associated with a high rate of mortality and its prevalence in the United States and in Western Europe is increasing. Cirrhosis is the strongest and the most common known risk factor for HCC, usually due to hepatitis C virus (HCV) and hepatitis B virus (HBV) infections. However, different lines of evidence identify in non-alcoholic fatty liver disease (NAFLD) a possible relevant risk factor for occurrence of HCC. Given the continuing increase in the prevalence of obesity and diabetes, the incidence of non-alcoholic steatohepatitis-related HCC may also be expected to increase, and a potential role of behav…

Update on new approaches in the management of hepatocellular carcinoma

Abstract: Hepatocellular carcinoma (HCC) is a major health problem. It is currently the third cause of cancer-related death, it is highly prevalent in the Asia–Pacific region and Africa, and is increasing in Western countries. The natural history of HCC is very heterogeneous and prediction of survival in individual patients is not satisfactory because of the wide spectrum of the disease. During the past decade, major advances have been achieved in prevention, through better surveillance of patients at risk, and in therapy through better surgical and ablative therapies and multimodal treatment approaches. Moreover, the increasing knowledge of molecular hepatocarcinogenesis provides the oppor…

Treatment of hepatocellular carcinoma: present and future

Hepatocellular carcinoma is a major health problem. It is the sixth most common cancer worldwide and the third most common cause of cancer-related death. Despite the availability of several treatment opportunities, diagnosis is still made in an advanced phase, limiting application of most therapeutic choices that currently are based on the Barcelona Clinic Cancer Liver Classification and include surgical resection, orthotopic liver transplantation and ablative methods for very early and early disease, arterial chemoembolization for intermediate stages and systemic therapy with sorafenib for advanced hepatocellular carcinoma. Thanks to novel advancements in knowledge of molecular pathogenesi…

The complex interplay between vitamin D deficiency and diabetes

It has been recently highlighted the link between vitamin D and metabolic and immunological pro- cesses, which established its role as an essential component of human health preservation. Vitamin D has been defined as natural immune modulators, and through the activation of its receptors (VDRs), it regulates calcium metabolism, cellular growth, proliferation and apoptosis, and other immunological functions. In this setting, vita- min D has also been reported to influence glucose regulation via effects on insulin secretion and action. Vitamin D deficiency is strongly associated with obesity mostly due to the storage of vitamin D in adipose tissue because of its lipophilic properties. The dec…

Survival of patients with hepatocellular carcinoma (HCC) treated by percutaneous radio-frequency ablation (RFA) is affected by complete radiological response.

Background: Radio-frequency ablation (RFA) has been employed in the treatment of Barcelona Clinic Liver Cancer (BCLC) early stage hepatocellular carcinoma (HCC) as curative treatments. Aim: To assess the effectiveness and the safety of RFA in patients with early HCC and compensated cirrhosis. Methods: A cohort of 151 consecutive patients with early stage HCC (122 Child-Pugh class A and 29 class B patients) treated with RFA were enrolled. Clinical, laboratory and radiological follow-up data were collected from the time of first RFA. A single lesion was observed in 113/151 (74.8%), two lesions in 32/151 (21.2%), and three lesions in 6/151 (4%) of patients. Results: The overall survival rates …

Hepatocellular carcinoma enhancement on contrast-enhanced CT and MR imaging: response assessment after treatment with sorafenib: preliminary results

PURPOSE: This study was undertaken to compare response evaluation criteria in solid tumours (RECIST) 1.1 and modified RECIST (mRECIST) in patients with unresectable hepatocellular carcinoma (HCC) on sorafenib, and to describe HCC enhancement changes before and after sorafenib treatment. METHODS AND MATERIALS: Seventeen patients (12 men, 5 women; mean age 69 years; age range 58-79 years) were included. Tumour response was assessed according to RECIST and mRECIST. Two readers placed a region of interest (ROI) within each target lesion, on the portion showing enhancement during the arterial phase. The lesion attenuation values measured within the ROIs on computed tomography or the signal inten…

Natural history of untreatable hepatocellular carcinoma: A retrospective cohort study

Abstract AIM: To investigate the clinical course of untreatable hepatocellular carcinoma (HCC) identified at any stage and to identify factors associated with mortality. METHODS: From January 1999 to December 2010, 320 out of 825 consecutive patients with a diagnosis of HCC and not appropriate for curative or palliative treatments were followed and managed with supportive therapy. Cirrhosis was diagnosed by histological or clinical features and liver function was evaluated according to Child-Pugh score. The diagnosis of HCC was performed by Ultra-Sound guided biopsy or by multiphasic contrast-enhanced computed tomography or gadolinium-enhanced magnetic resonance imaging. Data were collected…

Assessment of treatment response in hepatocellular carcinoma: a review of literature

NT pro BNP plasma level and atrial volume are linked to the severity of liver cirrhosis.

BACKGROUND AND AIMS: Plasma levels of NT-pro-BNP, a natriuretic peptide precursor, are raised in the presence of fluid retention of cardiac origin and can be used as markers of cardiac dysfunction. Recent studies showed high levels of NT pro BNP in patients with cirrhosis. We assessed NT pro-BNP and other parameters of cardiac dysfunction in patients with cirrhosis, with or without ascites, in order to determine whether the behaviour of NT pro BNP is linked to the stage of liver disease or to secondary cardiac dysfunction. METHODS: Fifty eight consecutive hospitalized patients mostly with viral or NAFLD-related cirrhosis were studied. All underwent abdominal ultrasound and upper GI endoscop…
