BACKGROUND The prognosis of patients with hepatocellular carcinoma (HCC) with portal vein tumor thrombosis (PVTT) is extremely poor. The aim of this study was to elucidate the efficacy of hepatic arterial infusion chemotherapy (HAIC) for patients with advanced HCCs. METHODS Forty-eight HCC patients with PVTT were treated by HAIC via a subcutaneously(More)
Two cases of infantile carcinoma of the pancreas were diagnosed as pancreatoblastoma based on the morphogenesis of the tumors. These encapsulated tumors adhered to the head of the pancreas and to the descending portion of the duodenum. Histologic examination revealed an organoid structure made up of cords or nodules of squamoid cells with elongated nuclei(More)
OBJECTIVE The prognosis of advanced hepatocellular carcinoma remains poor. The aim of this study was to compare the efficacy of hepatic artery infusion chemotherapy and transcatheter arterial Lipiodol chemoembolization for treatment of advanced tumor. SUBJECTS AND METHODS. Thirty-seven patients with hepatocellular carcinoma and unresectable tumors were(More)
To clarify the mechanisms of thrombocytopenia observed in patients with chronic hepatitis B treated with interferon. We studied six patients with chronic active hepatitis B who received intramuscular injections of natural interferon-alpha (3 or 5 million IU/day) for 4 weeks. Peripheral blood platelet counts, bone marrow findings, and platelet kinetics,(More)
PURPOSE We investigated the differences in clinical features between alpha-fetoprotein (AFP)-predominant hepatocellular carcinoma (HCC) and protein induced by vitamin K absence or antagonist-II (PIVKA-II)-predominant HCC, especially regarding host factors thought to contribute to hepatocarcinogenesis in chronic hepatitis C virus (HCV) infection. METHODS(More)
OBJECTIVE We determined the prevalence of patients with hepatocellular carcinoma (HCC) who were positive for only anti-hepatitis B core (anti-HBc) antibody among 284 Japanese patients and compared their clinical features to those who were hepatitis B surface antigen positive [HBsAg(+)]. METHODS Serum HBsAg and anti-hepatitis C virus (anti-HCV) antibody(More)
OBJECTIVE To elucidate the usefulness of monitoring Lens culinaris agglutinin-reactive alpha-fetoprotein (AFP-L3) and des-gamma-carboxy prothrombin detected with a revised kit (DCP-R) as clues to the diagnosis of recurrent hepatocellular carcinoma (HCC). METHODS A total of 57 patients with HCC were enrolled in the study. They were classified into two(More)
BACKGROUND Sorafenib, an oral multikinase inhibitor, was approved for the treatment of advanced hepatocellular carcinoma (HCC), but has not been adequately evaluated for safety and effectiveness in Japanese patients with advanced HCC. AIMS The purpose of this study was to prospectively assess the efficacy, safety, and risk factors for survival in patients(More)
Spontaneous regression of hepatocellular carcinoma (HCC) is rare. There are few reports discussing spontaneous regression associated with serum lens culinaris agglutinin-reactive alpha fetoprotein (AFP-L3). We describe a case of HCC with a high level of AFP-L3, which showed a rapid increase in alpha fetoprotein (AFP) concentration after partial spontaneous(More)
PURPOSE We investigated the unsettled issue of whether seropositivity for antibody to hepatitis B core antigen (anti-HBc) affects characteristics of hepatitis C virus (HCV)-related hepatocellular carcinoma (HCC). METHODS Antibody status was determined by enzyme immunoassay in 243 patients with this cancer, and associations with clinicopathologic(More)
