Lung cancer is the leading cause of death by cancer, and is a major sanitary concern worldwide. Some nutrients, such as ω-9 fatty acids, have been proposed as anticancer agents. Thus, an olein-enriched diet was assayed in a murine model of lung adenocarcinoma (LAC-1) to evaluate neoplastic and paraneoplastic evolution in BALB/c mice. The organic assimilation of dietary fatty acids was confirmed in liver by gas chromatography. This experimental oleic acid-containing diet increased animal survival and tumour latency (analysed by the Kaplan-Meier method), improving neoplastic evolution and general status, with weak effects on the paraneoplastic syndrome (thymus atrophy, splenomegaly, splenocyte response to mitogen, blood anaemia, and leucocytosis)...

BACKGROUND: The optimal transcatheter embolization strategy for patients with unresectable hepatocellular carcinoma (HCC) remains elusive. We conducted a systematic review and network meta-analysis (NMA) of different embolization options for unresectable HCC. METHODS: Medical databases were searched for randomized controlled trials evaluating bland transarterial embolization (TAE), conventional TACE, drug-eluting bead chemoembolization (DEB-TACE), or transarterial radioembolization (TARE), either alone or combined with adjuvant chemotherapy, or local liver ablation, or external radiotherapy for unresectable HCC up to June 2017...

Hepatocellular carcinoma is one of the most common cancers in the world, and it is influenced by agents such as DEN, 2-AAF, phenobarbital, alcohol, aflatoxin B1 metabolite or hepatitis viruses (B and C). Oxidative stress is becoming recognized as a key factor in the progression of hepatocarcinogenesis. Reactive oxygen species can play a leading role in initiation and promotion of hepatic carcinogenesis. The metabolites of DEN Diethylnitrosamine (DEN) mediate the binding of tumour promoters by covalently binding to the DNA with one or two oxidation-providing electrons...

BACKGROUND: HCC in Egypt usually occurs in HCV cirrhotic livers with poor prognosis due to late diagnosis. High hnRNPK & low Claudin-4 profiles indicate Epithelial Mesenchymal Transition (EMT), malignant transformation and high-grade tumours. AIM: We studied the immunohistochemical expression of hnRNPK and Claudin-4 in HCV induced early HCC (eHCC) and adjacent liver tissue in Egyptian patients to improve eHCC detection in cirrhotic livers with better curative therapy options...

It has been suggested that hepatobiliary carcinomas are less frequent in Wilson's disease (WD) than in liver diseases of other etiology. However, the protective role of copper against malignancies is debated. Only a few cases of cholangiocarcinoma (CCC) in WD have been published. Here we report on a case of a 47-year-old male H1069Q homozygous, Kayser-Fleischer ring positive WD patient with a low ceruloplasmin level who was followed up and treated with chelating agents throughout nine years. The patient presented with neurological symptoms and liver cirrhosis at diagnosis...

BACKGROUND: Hepatocellular carcinoma (HCC) is increasingly prevalent in people living with HIV. Systemic inflammation is a prognostic factor requiring validation in HIV-associated HCC. AIMS: Using a multi-centre database of consecutive HCC cases, we investigated the prognostic role of a panel of inflammatory markers, including neutrophil to lymphocyte ratio (NLR), using univariate and multivariate survival analyses. RESULTS: Fifty-nine patients with HIV-associated HCC secondary to hepatitis C (69%) or B virus infection (32%) were identified...

Renal cell carcinoma accounts for 2%-3% of all malignancies in adults. It spreads via direct extension, lymphatic route as well as haematogenous route. Lymph nodes, lungs, bone, liver and brain are the usual sites for its metastatic spread. In the presence of limited metastatic disease with potentially resectable metastases, surgery offers the best chances of cure. In the present case, we describe a case of renal cell carcinoma with a solitary metastasis to the sigmoid mesentery in a patient with Von Hippel-Lindau syndrome...

We are presenting the case study of the patient diagnosed at the age of 37 with liver cirrhosis due to genotype 1b hepatitis C virus infection. At the age of 46, he was diagnosed with hepatocellular carcinoma with subsequent resection of the tumour in May 2015. In December 2015, the treatment was started with ombitasvir, paritaprevir/ritonavir and dasabuvir (3D) with ribavirin (RBV) 1000 mg per day. After 24 days of this treatment, the patient received a deceased donor liver transplantation, followed by 18-day interruption of 3D therapy...

Stereotactic body radiotherapy (SBRT) is increasingly used in the management of unresectable liver metastases and hepatocellular carcinoma (HCC) as it allows delivery of high-dose conformal radiotherapy with limited toxicities. However, it may be difficult to differentiate viable tumour from radiotherapy-related changes after SBRT. The imaging changes observed after SBRT may also differ from those observed following conventionally fractionated radiotherapy. Hence, we aim to review the imaging changes that occur within the tumour and adjacent normal liver after SBRT which may help to identify local relapse in clinical practice...

The tyrosine kinase inhibitor erlotinib targets the receptor of epidermal growth factor (EGFR) involved in development of hepatocellular carcinoma (HCC). Although inefficient in established HCC, erlotinib has been recently proposed for HCC chemoprevention. Since Cyp3A4 and Cyp1A2 enzymes metabolize erlotinib in the liver, the insights into the mechanisms of erlotinib effects on liver cells with maintained drug metabolizing activity are needed. We applied erlotinib to both commercially available (SNU398, Huh7) and established in Austria HCC cell lines (HCC-1...

Near-infrared fluorescence (NIRF) dyes have recently emerged as promising tools for non-invasive imaging of different types of cancers. Here, we explored the potential utility of a NIRF DZ-1 dye, with dual imaging and tumour targeting functions, in hepatocellular carcinoma (HCC). We showed the preferential uptake of DZ-1 by HCC cells in vitro and in derived subcutaneous/orthotopic tumour xenografts, accompanied by a minimal effect on normal cells. DZ-1 simplified tumour growth profiling as well, since we were able to correlate NIRF signals with tumour volume and/or tumour-emitting luminescence in mice...

Invasion and metastasis are the primary causes of mortality from hepatocellular carcinoma (HCC). Effective inhibition against participants in the tumourigenesis and metastasis process is critical for treatment of HCC. Wnt3a is involved in the development and metastasis of many malignant tumours. However, the specific mechanisms of Wnt3a-mediated cell proliferation, invasion and metastasis in HCC remain unclear. In this study, we found that Wnt3a and its target gene c‑Myc showed higher expression in tumour tissues than normal liver tissues in HCC patients; 71...

BACKGROUND: Integrator complex subunit 6 (INTS6) was found to play a tumour suppressing role in certain types of solid tumours. In this study, we wanted to determine the expression level of INTS6 in hepatocellular carcinoma (HCC) and evaluate its clinical characteristics and mechanisms in HCC patients (Lui and Lu, European Journal of Cancer, 51:S94, 2015). METHODS: First, we used a microarray analysis to explore the mRNA expression levels in HCC and paired normal liver tissues; second, we used qRT-PCR to measure the INTS6 mRNA levels in a cohort of 50 HCC tissues and adjacent normal liver tissues; third, we used Western blot analyses to detect the INTS6 protein levels in 20 paired HCC and normal liver tissues; fourth, we used immunohistochemistry to determine the INTS6 expression levels in 70 archived paraffin-embedded HCC samples...

BACKGROUND: Diagnosis of hepatocellular carcinoma (HCC) can be established with near certainty by correlating radiological imaging with clinical presentation. However, in the absence of diagnostic certainty, biopsy of liver tissue is mandatory for optimal management. We present our management of a patient with advanced liver disease who presented with an IVC mass extending into the right atrium, with co-existing liver lesions not meeting criteria for an imaging diagnosis of HCC.

Hepatocellular carcinoma (HCC) is a common cancer worldwide and represents the outcome of the natural history of chronic liver disease. The growing rates of HCC may be partially attributable to increased numbers of people with non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis (NASH). However, details of the liver-specific molecular mechanisms responsible for the NAFLD-NASH-HCC progression remain unclear, and mouse models that can be used to explore the exact factors that influence the progression of NAFLD/NASH to the more chronic stages of liver disease and subsequent HCC are not yet fully established...
