BACKGROUND The appropriate surgical approach for hepatocellular carcinoma (HCC) patients of Child-Pugh class B is unclear. The aim of this study was to clarify the prognostic factors after hepatectomy in Child-Pugh class B patients and to delineate the selection criteria for hepatectomy. METHODS One hundred fifty patients of Child-Pugh class B who(More)
Hepatic steatosis is one of the most common hepatic disorders in developed countries. The epidemic of obesity in developed countries has increased with its attendant complications, including metabolic syndrome and non-alcoholic fatty liver disease. Steatotic livers are particularly vulnerable to ischemia/reperfusion injury, resulting in an increased risk of(More)
BACKGROUND Although several studies have shown that perioperative blood transfusion is a poor prognostic factor of outcome after hepatectomy for hepatocellular carcinoma (HCC), the impact of perioperative blood transfusion on the prognosis of HCC remains unknown. METHODS Data from 835 patients (76 transfused patients and 759 nontransfused patients) who(More)
Fatty liver (FL) is associated with development of hepatocellular carcinoma (HCC). However, whether FL itself promotes the progression of HCC is unclear. We recently found that hepatic stellate cells (HSCs) were prominently activated in the steatotic liver. Here, we investigated whether steatotic livers promote HCC progression and whether HSCs of steatotic(More)
AIM This study aimed to validate the prognostic value of the Glasgow Prognostic Score (GPS) in patients who underwent living donor liver transplantation (LDLT) for hepatocellular carcinoma (HCC). METHODS Data were retrospectively collected for HCC patients who underwent LDLT. Univariate and multivariate analyses were performed to identify variables(More)
BACKGROUND Hypoxia inducible factor-1α (HIF-1α) is a major regulator of tumorigenesis in hypoxic conditions and therefore represents a potential therapeutic target in colorectal cancer (CRC). Clinical significance of HIF-1α expression in liver metastases has not been elucidated. Therefore, this study aimed to clarify the clinical significance of HIF-1α(More)
BACKGROUND The preferred choice between surgical treatment and radiofrequency ablation (RFA) for the treatment of small resectable hepatocellular [corrected] carcinoma (HCC) has become a subject for debate. METHODS We compared the results of hepatic resection (n = 199) with those of RFA (n = 87), of which 69 patients were treated with transcatheter(More)
BACKGROUND/PURPOSE Although many factors related to the tumor or the hepatic functional reserve may affect the outcome of partial hepatectomy for hepatocellular carcinoma (HCC), these factors have not yet been intensively investigated in patients with solitary HCC. The purpose of this study is to determine the clinicopathological factors influencing the(More)
BACKGROUND.: Although the outcome of liver transplant patients with hepatocellular carcinoma (HCC) has improved with the introduction of strict criteria, tumor recurrence still remains a significant problem. Sphingosine-1-phosphate (S1P) is a phospholipid mediator that can induce diverse cellular responses, such as proliferation, migration, adhesion, and(More)
BACKGROUND & AIMS Hepatic stellate cells are thought to play a role in modulating intrahepatic vascular resistance based on their capacity to contract via Rho signaling. We investigated the effect of a Rho-kinase inhibitor on ischemia-reperfusion injury in the steatotic liver. METHODS Steatotic livers, induced by a choline-deficient diet in rats, were(More)
