Diffusion-weighted magnetic resonance imaging predicts malignant potential in small hepatocellular carcinoma.

Background: Poor differentiation and microvascular invasion are indicators of poor outcome after hepatectomy for patients with small hepatocellular carcinoma (HCC).

Aims: We investigated whether gadoxetic acid-enhanced and diffusion-weighted magnetic resonance imaging (MRI) could predict these factors before hepatectomy.

Methods: Between July 2008 and April 2012, 75 patients who underwent hepatectomy for small HCCs (diameter: ≤3cm, tumor number: ≤3) were consecutively enrolled.

The systemic inflammatory response as a prognostic factor for advanced hepatocellular carcinoma with extrahepatic metastasis.

Several indices have been proposed to evaluate the systemic inflammatory response (SIR), which has been reported to be a useful prognostic factor in various types of cancer. We investigated the usefulness of the Glasgow Prognostic Score (GPS), neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) as prognostic factors in patients with advanced hepatocellular carcinoma (HCC) with extrahepatic metastasis (stage IVB). Between April, 1997 and March, 2013, a total of 434 HCC patients who developed extrahepatic metastasis were enrolled in the present study.

Methods: We enrolled 52 HCC patients with portal vein tumor thrombosis.

Effect of pioglitazone on outcome following curative treatment for hepatocellular carcinoma in patients with hepatitis C virus infection: A prospective study.

Pioglitazone is an insulin sensitizer used for the treatment of diabetes mellitus (DM). DM with insulin resistance is a risk factor for hepatocellular carcinoma (HCC) in patients with hepatitis C virus (HCV) infection. We aimed to investigate the effects of pioglitazone on HCC recurrence following treatment in HCV-infected patients.

Usefulness of short-term eltrombopag treatment as a supportive treatment in hepatocellular carcinoma patients with cirrhosis and severe thrombocytopenia: A report of two cases.

Eltrombopag is an oral thrombopoietin (TPO) receptor agonist that increases platelet counts in patients with idiopathic thrombocytopenic purpura and in patients with liver cirrhosis. When cirrhotic patients with thrombocytopenia undergo elective invasive procedures, eltrombopag treatment reduces the requirement for platelet transfusions. However, TPO is known to have proliferative effects on hepatic progenitor cells and hepatic sinusoidal endothelial cells, which indicates that eltrombopag may accelerate tumor progression.

Clinical characteristics and prognostic factors for advanced hepatocellular carcinoma with extrahepatic metastasis.

Hepatocellular carcinoma (HCC) is one of the most common malignancies worldwide. The aim of this study was to evaluate whether there are differences in the clinical characteristics and survival between patients with advanced HCC with extrahepatic metastasis who received and those who did not receive previous treatment.

The significance of classifying microvascular invasion in patients with hepatocellular carcinoma.

Background: Microvascular invasion (MVI) has been recognized as a risk factor for outcome following curative resection in hepatocellular carcinoma (HCC). Because MVI can range from few to many invaded vessels, we evaluated the significance of MVI classification in this study.

Methods: Between January 1995 and December 2010, 207 consecutive patients who underwent curative resection for HCC within Milan criteria were included in this retrospective study.

Effect of occult hepatitis B virus infection on the early-onset of hepatocellular carcinoma in patients with hepatitis C virus infection.

Although overt hepatitis B virus (HBV) infection promotes the onset of hepatocellular carcinoma (HCC) in hepatitis C virus (HCV)-infected patients, the effect of occult HBV infection remains unclear. The aim of this study was to investigate the effect of occult HBV infection on the early-onset of HCC in HCV-infected patients. A total of 173 HCC patients with HCV infection were enrolled and classified into 2 groups according to the median age of HCC onset: the early-onset group (n=91; 61.

Methods: Between May 2009 and December 2010, 96 Japanese patients with advanced HCC (76 male, 20 female, mean age: 70.

Serum vascular endothelial growth factor as a predictor of response and survival in patients with advanced hepatocellular carcinoma undergoing hepatic arterial infusion chemotherapy.

Background: Hepatic arterial infusion chemotherapy (HAIC) has been recognized as a useful therapeutic modality for patients with advanced hepatocellular carcinoma (HCC). The aim of this study was to investigate the association between serum vascular endothelial growth factor (VEGF) levels and the therapeutic effect of HAIC and the survival of patients undergoing HAIC.

Methods: Seventy-one patients with advanced HCC underwent HAIC through a subcutaneously implanted infusion port.

Total and high molecular weight adiponectin and hepatocellular carcinoma with HCV infection.

Background: Adiponectin is shown to be inversely associated with development and progression of various cancers. We evaluated whether adiponectin level was associated with the prevalence and histological grade of hepatocellular carcinoma (HCC), and liver fibrosis in patients with hepatitis C virus (HCV) infection.

Methods: A case-control study was conducted on 97 HCC patients (cases) and 97 patients (controls) matched for sex, Child-Pugh grade and platelet count in patients with HCV infection.

Insulin resistance and chronic liver disease.

Increased insulin resistance is frequently associated with chronic liver disease and is a pathophysiological feature of hepatogenous diabetes. Distinctive factors including hepatic parenchymal cell damage, portal-systemic shunting and hepatitis C virus are responsible for the development of hepatogenous insulin resistance/diabetes. Although it remains unclear whether insulin secretion from pancreatic beta cells is impaired as it is in type 2 diabetes, retinopathic and cardiovascular risk is low and major causes of death in cirrhotic patients with diabetes are liver failure, hepatocellular carcinoma and gastrointestinal hemorrhage.

Adipocytokine involvement in hepatocellular carcinoma after sustained response to interferon for chronic hepatitis C.

Aim:   Interferon (IFN) dramatically reduces the risk of hepatocellular carcinoma (HCC) after a sustained virological response (SVR) to chronic hepatitis C (CH-C). However, HCC still develops in some patients after SVR. To evaluate metabolic factors in patients with HCC occurring after SVR and to determine whether insulin resistance and adipocytokines were involved in this etiology.

Recent progress in the management of hepatocellular carcinoma detected during a surveillance program in Japan.

Aim:   This study explored recent improvements in the management of hepatocellular carcinoma (HCC) diagnosed during surveillance.

Methods:   The subjects were 1074 patients with HCC, subdivided into three groups. Group A comprised 211 patients for whom HCC was detected during periodic follow-up examinations at Kurume University School of Medicine, Group B comprised 544 patients diagnosed with HCC during periodic follow-up examinations at other institutions, and, Group C comprised 319 patients with HCC detected incidentally or because of symptoms.

Characteristic expression pattern of oxidative stress in livers with cryptogenic hepatocellular carcinoma.

The mechanism responsible for the development of hepatocellular carcinoma (HCC) in the setting of oxidative stress has yet to be clearly defined. We studied the role of oxidative stress in hepatocarcinogenesis in subjects without underlying chronic viral hepatitis. The subjects were 24 patients negative for serum hepatitis B surface antigen and hepatitis C antibody tests, who underwent hepatic resection for HCC (Group N).

The pathogenesis, complications and therapeutic strategy for hepatitis C virus-associated insulin resistance in the era of anti-viral treatment.

Recent experimental and clinical studies have shown that chronic hepatitis C virus (HCV) infection causes insulin resistance. Since insulin resistance decreases response to antiviral treatments, promotes inflammatory and fibrogenic reactions and increases a risk of hepatocellular carcinoma (HCC), amelioration of insulin resistance may be a novel therapeutic target, which could improve the prognosis in patients with HCV-related chronic liver disease. Despite the increased awareness of health risk of insulin resistance, there is no common therapeutic strategy for HCV-associated insulin resistance.

Thrombocytopenia, an important interfering factor of antiviral therapy and hepatocellular carcinoma treatment for chronic liver diseases.

In patients with chronic liver diseases, thrombocytopenia is a common manifestation which interferes with antiviral therapy for hepatitis C virus (HCV), and with hepatocellular carcinoma (HCC) treatment. While thrombopoietin-receptor agonist is expected to improve thrombocytopenia for patients with chronic liver diseases in 2-3 weeks, there is still a lack of fundamental data about short-term variations in the natural course of platelet count in cirrhotic patients, and the impact of thrombocytopenia on antiviral therapy for HCV-infected patients and patients being treated for HCC. The aims of this study are to investigate sequential changes in platelet count and the impact of thrombocytopenia on antiviral therapy and HCC treatment in patients with chronic liver diseases.

Pigment epithelium-derived factor inhibits lysosomal degradation of Bcl-xL and apoptosis in HepG2 cells.

Pigment epithelium-derived factor (PEDF) has several biological actions on tumor cells, but its effects are cell-type dependent. The aim of this study was to examine the pathophysiological role of PEDF in hepatocellular carcinoma (HCC). PEDF expression was examined in various hepatoma cell lines and human HCC tissues, and was seen in various hepatoma cell lines including HepG2 cells.

Transarterial chemoembolization as salvage therapy after unsuccessful hepatic arterial infusion chemotherapy in advanced hepatocellular carcinoma.

The prognosis for advanced hepatocellular carcinoma (HCC) remains unsatisfactory. Transarterial chemoembolization (TACE) and/or hepatic arterial infusion chemotherapy (HAIC) have been reported to be useful options. However, there are few reports of salvage therapies for patients without a curative response to initial chemotherapy.
