BACKGROUND & AIMS Transarterial chemoembolization (TACE) is a widely used treatment for hepatocellular carcinoma. In order to maximize its therapeutic efficacy, doxorubicin-loaded drug-eluting beads have been developed to deliver higher doses of the chemotherapeutic agent and to prolong contact time with the tumor. The purpose of this study was to evaluate(More)
Reactivation of hepatitis B virus (HBV) during chemotherapy is well documented. However, there are limited data on this complication in patients with hepatocellular carcinoma (HCC) undergoing transarterial chemotherapy. The aim of this study was to evaluate the efficacy of preemptive lamivudine therapy in reducing hepatitis due to HBV reactivation in(More)
Recent findings suggest that bone marrow (BM) cells have the capacity to differentiate into a variety of cell types including endocrine cells of the pancreas. We report that BM derived cells, when cultured under defined conditions, were induced to trans-differentiate into insulin-producing cells. Furthermore, these insulin-producing cells formed aggregates(More)
Liver transplantation (LT) is a curative modality for hepatocellular carcinoma (HCC), especially in patients with cirrhosis. However, there are still risks of recurrence. C-reactive protein (CRP), an acute-phase inflammatory reactant that is synthesized by hepatocytes, has been related to the prognosis of various malignancies, including HCC. In this study,(More)
We evaluated the long-term effect of stereotactic body radiation therapy (SBRT) for primary small hepatocellular carcinoma (HCC) ineligible for local therapy or surgery. Forty-two HCC patients with tumors ≤ 100 cc and ineligible for local ablation therapy or surgical resection were treated with SBRT: 30-39 Gy with a prescription isodose range of 70-85%(More)
BACKGROUND AND AIMS The underlying molecular mechanisms of hepatocellular carcinoma (HCC) remain poorly understood due to its complex development process. The human T cell-specific transcription factor sex-determining region Y-related high-mobility group (HMG) box 4 (SOX4) has been linked to development and tumorigenesis. In this study, we characterized the(More)
BACKGROUND AND AIMS The ability of the bone marrow cells to differentiate into liver, pancreas, and other tissues led to the speculation that these cells might be the source of adult stem cells found in these organs. The present study analyzed whether the bone marrow cells are a source of hepatic oval cells involved in rat liver regeneration induced by(More)
Liver cirrhosis is one of the major complications of hepatitis C virus (HCV) infection, but the mechanisms underlying HCV-related fibrogenesis are still not clear. Although the roles of HCV core protein remain poorly understood, it is supposed to play an important role in the regulation of cellular growth and hepatocarcinogenesis. The aim of this study was(More)
PURPOSE To identify the parameters that predict hepatic toxicity and deterioration of hepatic function. MATERIALS AND METHODS A total of 47 patients with small unresectable primary hepatocellular carcinoma received hypofractionated stereotactic body radiotherapy (SBRT) using the CyberKnife. Of those, 36 patients received no other local treatments that(More)
BACKGROUND/AIMS Reactivation of hepatitis B virus (HBV) replication is a well-known complication in cancer patients receiving chemotherapy. The aims of this study were to determine the incidence of HBV reactivation in hepatocellular carcinoma (HCC) patients undergoing transarterial chemo-lipiodolization, and to clarify factors contributing to HBV(More)
