UNLABELLED Because (18)F-FDG PET has insufficient sensitivity for the detection of hepatocellular carcinoma (HCC), (11)C-acetate PET has been proposed as another technique for this use. We prospectively evaluated the value of PET/CT using these 2 tracers for the detection of primary and metastatic HCC. METHODS One hundred twelve patients (99 with HCC, 13(More)
PURPOSE To identify the dose-volumetric parameters associated with the risk of radiation-induced hepatic toxicity (RIHT) in hepatocellular carcinoma patients treated with three-dimensional conformal radiotherapy. METHODS AND MATERIALS A total of 105 hepatocellular carcinoma patients underwent three-dimensional conformal radiotherapy (total dose range,(More)
It is well known that requirements engineering plays a critical role in software quality. The use case approach is a requirements elicitation technique commonly used in industrial applications. Software requirements are stated as a collection of use cases, each of which is written in the user’s perspective and describes a specific flow of events in the(More)
We prospectively investigated the association between a change of serum vascular endothelial growth factor (VEGF) level after transcatheter arterial chemoembolization (TACE) and hepatocellular carcinoma (HCC) patient prognosis. The study involved 147 patients with unresectable HCC treated at the National Cancer Center, Korea, between July and December 2005.(More)
Intrahepatic cholangiocarcinoma (ICC) is the second most common primary hepatic malignancy, but the studies for the outcome after resection of ICC are rare. The aim of this study was to elucidate outcomes and prognostic factors of ICC in patients undergoing hepatic resection. A retrospective study was conducted with a total of 63 patients who underwent(More)
OBJECTIVES To evaluate 3-dimensional conformal radiotherapy (3D-CRT) of unresectable hepatocellular carcinoma (HCC) patients for whom transcatheter arterial chemoembolization (TACE) was ineffective or unsuitable, and to determine whether tumor response and portal vein thrombosis (PVT) response to treatment were prognostic factors for overall survival.

Several studies have reported that ABO blood group, hepatitis B virus (HBV) and hepatitis C virus (HCV) infection contribute to the development of pancreatic cancer. The aim of this study was to evaluate the association between these factors and pancreatic cancer in the Korean population. We retrospectively recruited 753 patients with pancreatic cancer and(More)
BACKGROUND The efficacy and complications of covered self-expandable metal stents (SEMS) remain controversial. OBJECTIVE We conducted this study to compare the efficacies and complication rates of covered and uncovered SEMS in malignant biliary obstruction. DESIGN Data on patients who underwent endoscopic retrograde biliary drainage with covered or(More)
BACKGROUND/AIMS No reliable nationwide clinical data about chronic pancreatitis (CP) was available in Korea. The etiology and clinical features of CP were investigated using a multicenter nationwide study. METHODS 814 cases of CP were enrolled retrospectively over the past 4 years at 13 hospitals. The following data were obtained from all patients:(More)
AIM To investigate prevalence of Clonorchis sinensis in patients with gastrointestinal symptoms, and the relation of the infection to hepatobiliary diseases in 26 hospitals in Korea. METHODS Consecutive patients who had been admitted to the Division of Gastroenterology with gastrointestinal symptoms were enrolled from March to April 2005. Of those who had(More)
