conclusions verapamil and rifampin were found specific and effective against p-gp expression in hcc. in conclusion, treatment efficacy of most anticancer drugs is increased in combination with verapamil and rifampin against most advanced hcc. objectives the aim of this study was to elucidate the effect of potent carcinogen nitrosamine with and without verapamil and rifampin drugs on p-gp expres...

the imaging of hepatocellular carcinoma (hcc) is challenging and plays a crucial role in the diagnosis and staging of the disease. a variety of imaging modalities, such as ultrasound, computed tomography (ct), magnetic resonance imaging (mri) and nuclear medicine are currently used in evaluating patients with hcc. although the best option for the treatment of these cases is hepatic resection or...

background: hepatitis b virus (hbv) infection is the most common cause of end-stage liver disease in iran. more than 70% of cases are negative for the hepatitis b e antigen (hbeag) and have a long-term response to antiviral therapy, as well as a high relapse rate after discontinuing lamivudine or interferon. these features could be due, in part, to genetic variation of the hbv genome. materials...

hepatocellular carcinoma (hcc) represents one of the most common neoplasms worldwide.  liver trasnplantation (lt) is the treatment of choice for selected group of patients with hcc. lt is actually a consolidated therapeutic option for hcc because it cures both tumor and underlying cirrhosis. in 1996, the publication of a pivotal prospective study on less than 50 patients, transplanted for hcc u...

Endobronchial metastases from hepatocellular carcinoma are very rare. Up to date, no more than 7 cases were reported. The authors present a case of 20-year old female with metastatic hepatocellular carcinoma to superior lobar bronchus. Examination of cytological and small biopsy specimens obtained from bronchoscopy revealed characteristic microscopic features and immunohistochemical profile of ...

PURPOSE Small molecule inhibitors of the mitogen-activated protein kinase (MAPK) pathway, such as sorafenib, represent novel treatment options for advanced hepatocellular carcinoma. The aim of our study was to identify downstream targets as biomarker candidates that are directly linked to the oncogenic MAPK pathway in hepatocellular carcinoma and correlate with inhibition of this pathway by mul...

BACKGROUND Endoscopic and pharmacological treatments significantly reduce recurrent esophageal variceal bleeding and improve the prognosis of cirrhotic patients. This study was aimed to evaluate the incidence, risk factors, treatment and prognosis of hepatocellular carcinoma after esophageal variceal bleeding. METHODS Patients with esophageal variceal bleeding underwent endoscopic or pharmaco...

OBJECTIVE T-cell lymphoma invasion and metastasis 1 (Tiam1) specifically activates Rho-like GTPases (e.g. Rac1) and Tiam1-Rac1 pathway affects the migration and invasion of many tumors, such as nasopharyngeal carcinoma, breast cancer and retinoblastoma. However, no studies have yet comprehensively examined the involvement of Tiam1-Rac1 pathway in hepatocellular carcinoma. In this study, we exam...

PURPOSE The development of hepatocellular carcinoma is associated with the chronic inflammation of the liver caused by various factors such as hepatitis B or C virus infection. Previously, we reported DNA binding protein A (dbpA) as a candidate molecule that can accelerate inflammation-induced hepatocarcinogenesis. DbpA belongs to the Y-box binding protein family, and Y-box binding protein-1 (Y...

OBJECTIVES To compare and contrast clinical characteristics and outcomes of hepatoblastoma or hepatocellular carcinoma in paediatric patients. DESIGN Retrospective study. SETTING University teaching hospital, Hong Kong. PATIENTS AND METHODS Medical records of 22 paediatric patients with hepatoblastoma (n=11) or hepatocellular carcinoma (n=11) admitted to Queen Mary Hospital between 1989 a...
