Multicenter retrospective study of initial treatment outcome and feasibility of initiating dose reduction of cabozantinib in unresectable hepatocellular carcinoma.

Aim: Cabozantinib (CAB), a multiple kinase inhibitor, has been approved for use in patients with previously treated unresectable hepatocellular carcinoma (uHCC). However, real-world clinical data are lacking, particularly clinical data regarding dose modifications of CAB. We analyzed the clinical outcomes of CAB in uHCC and compared treatment outcomes between the full- and reduced-dose groups.

The differing influence of several factors on the development of fatty liver with elevation of liver enzymes between genders with metabolic syndrome: A cross-sectional study.

Background: Nonalcoholic fatty liver disease (NAFLD) is known to be strongly associated with obesity, visceral fat, metabolic syndrome (MS), lifestyle, and lifestyle-related diseases in both males and females. However, the prevalence of NAFLD, MS, and clinical backgrounds is different between males and females.

Objective: We conducted a cross-sectional study to examine the differing influence of lifestyle-related factors and visceral fat on fatty liver (FL) with elevation of liver enzymes between males and females with MS.

Influence of light alcohol consumption on lifestyle-related diseases: a predictor of fatty liver with liver enzyme elevation in Japanese females with metabolic syndrome.

Background: Although heavy drinking is known to lead to liver injury, some recent studies have reported that light alcohol consumption (LAC) may play a protective role against fatty liver in the general population, and may even play a protective role against non-alcoholic fatty liver disease (NAFLD) in males with metabolic syndrome (MS). However, the association between LAC and fatty liver with liver enzyme elevation in females with MS is unclear.

Methods: Participants of this study were 20,853 females who underwent a regular health check-up between April 2008 and March 2012 at our hospital.

Visceral fat predominance is associated with non-alcoholic fatty liver disease in Japanese women with metabolic syndrome.

Aim: Metabolic syndrome (MS) is likely to be associated with non-alcoholic fatty liver disease (NAFLD). The prevalence of NAFLD in visceral fat type MS (V-type MS) is known to be higher than in subcutaneous fat type MS (S-type MS) in men with MS, and a larger subcutaneous fat area is reported to be not associated with NAFLD in women. We elucidated differences between V-type S-type MS in Japanese women with MS.

A patient with spinal metastasis from hepatocellular carcinoma discovered from neurological findings.

Although spinal tumors are uncommon, they may reduce survival or cause serious functional disorders in the extremities. Metastatic spinal tumors from malignant tumors can induce symptoms of spinal cord compression, such as paraplegia, quadriplegia, and vesicorectal disturbance, which are aggravated with progression of the diseases and time. We report a patient with hepatocellular carcinoma (HCC) who was suspected of having spinal lesions based on neurological findings, and a metastatic spinal tumor was found by imaging examination.

Historical changes of hospitalization in patients with hepatocellular carcinoma considering for clinical path preparation.

We examined the hospitalization time in 346 patients with hepatocellular carcinoma who were treated between January 1991 and March 2002 (486 admissions). A newly introduced IVR CT system and an advanced catheter shortened the mean time from 65.0 (1991) to 35.

Influence of an artificial pleural effusion technique on cardio-pulmonary function and autonomic activity.

Objective: Percutaneous treatment of hepatocellular carcinoma (HCC) located directly under the diaphragm is problematic because ultrasonic imaging is difficult, and the lung may be injured during the procedure. It has been reported that an infusion of 5% glucose solution into the thoracic cavity enables percutaneous treatment in such cases. However, the safety aspects of this have not been investigated.

Double radiofrequency ablation is more extensive with a spherical zone shape compared to single ablation in a pig liver model.

Objective: We compared the duration of ablation and the area of coagulation necrosis between a single ablation method (SAM) and a double ablation method (DAM) with a 'multitined expandable' electrode (LeVeen 2 cm) for radiofrequency ablation (RFA) using pig liver.

Method: In the SAM group, ablation was completed after the first roll-off. In the DAM group, an additional ablation was performed to achieve a second roll-off.

Effects of estradiol and progesterone on tumor necrosis factor alpha-induced apoptosis in human hepatoma HuH-7 cells.

Oxidative stress, including the generation of reactive oxygen species (ROS), is known to be involved in apoptosis. Preventing apoptosis may thereby induce a malignant transformation of liver tumor cells. Estradiol (E2) is a potent endogenous antioxidant.

Influence of large intrahepatic blood vessels on the gross and histological characteristics of lesions produced by radiofrequency ablation in a pig liver model.

Aims: To determine whether the presence of large intrahepatic blood vessels (>/=3 mm) affect radiofrequency (RF)-induced coagulation necrosis, the gross and histological characteristics of RF-ablated areas proximal to or around vessels were examined in normal pig livers.

Methods: An RF ablation treatment using a two-stepwise extension technique produced 12 lesions: six contained vessels (Group A), and the other six were localized around vessels (Group B).

Results: Gross examination revealed that the longest and shortest diameters of the ablated lesions were significantly larger in Group B than in Group A.

Antioxidant and antiapoptotic activities of idoxifene and estradiol in hepatic fibrosis in rats.

Oxidative stress plays a causative role in the development of hepatic fibrosis and apoptosis. Estradiol (E2) is an antioxidant, and idoxifene is a tissue-specific selective estrogen receptor modulator. We have previously demonstrated that E2 inhibits hepatic fibrosis in a rat model of hepatic fibrosis induced with dimethylnitrosamine (DMN), and suppresses activation of the nuclear factor (NF)-kappaB proinflammatory transcription factor in cultured rat hepatocytes undergoing oxidative stress.

Inhibitory effect of a soluble transforming growth factor beta type II receptor on the activation of rat hepatic stellate cells in primary culture.

Background/aims: Oxidative stress, including the generation of reactive oxygen species (ROS) that acts as a signaling mediator for transforming growth factor (TGF)-beta, plays a key role in hepatic fibrosis. Hepatic stellate cells (HSCs) produce and respond to TGF-beta in an autocrine manner with increased collagen expression. It has previously been reported that the adenovirus-mediated overexpression of a soluble receptor against the extracellular domain of the TGF-beta type II receptor prevents hepatofibrogenesis in vivo, although its inhibitory role and mechanism in HSC activation remains to be elucidated.

Interferon-alpha enhances biological defense activities against oxidative stress in cultured rat hepatocytes and hepatic stellate cells.

Oxidative stress has been implicated as a cause of hepatic fibrosis, and hepatic stellate cells (HSCs), which are the most important collagen-producing cell types, have been reported to be activated by lipid peroxidation products. Antioxidant enzymes such as superoxide dismutase (SOD) and glutathione peroxidase (GPx) provide a defense system that plays a critical role in protecting the cell from free radical damage, particularly lipid peroxidation. To elucidate the antioxidant activity of interferon-alpha (IFN-alpha), the effects of IFN-alpha on rat hepatocytes undergoing oxidative stress and HSCs in primary culture as well as isolated rat liver mitochondria were examined.

Echocardiographic Detection of Occult Cor Pulmonale During Exercise in Patients with Chronic Obstructive Pulmonary Disease.

We tested the ability of cycle ergometer exercise echocardiography to detect cases of occult cor pulmonale among 25 patients with chronic obstructive pulmonary disease (COPD). The M-mode echocardiographic ventricular septal motion, left ventricular shape determined by short-axis two-dimensional (2-D) echocardiography, and right and left ventricular pressure curves were recorded at rest and during exercise and were compared between patients. The ventricular septal motion was normal at rest in all of the patients.
