OBJECTIVE The purpose of this study was to determine whether the presence of intratumoral fat in hepatocellular carcinoma (HCC) could serve as an imaging biomarker to predict a favorable prognosis. MATERIALS AND METHODS After a search of the radiology and pathology databases from January 2002 to December 2010, a cohort of patients with fat-containing HCC(More)
UNLABELLED Microvascular invasion (MVI) in hepatocellular carcinoma (HCC) is an independent predictor of poor outcomes subsequent to surgical resection or liver transplantation (LT); however, MVI currently cannot be adequately determined preoperatively. Radiogenomic venous invasion (RVI) is a contrast-enhanced computed tomography (CECT) biomarker of MVI(More)
PURPOSE Hydroinfusion is a commonly used ancillary procedure during percutaneous thermal ablation of the liver that is used to separate and protect sensitive structures from the ablation zone. However, risks of hydroinfusion have not been systematically studied. The purpose of the present study was to systematically examine the frequency and severity of(More)
PURPOSE To evaluate preliminary outcomes after microwave ablation (MWA) of hepatocellular carcinoma (HCC) up to 5 cm and to determine the influence of tumor size. MATERIALS AND METHODS Electronic records were searched for HCC and MWA. Between January 2011 and September 2014, 173 HCCs up to 5 cm were treated by MWA in 129 consecutive patients (89 men, 40(More)
OBJECTIVE The objective of our study was to determine quantitative differences to differentiate low-grade from high-grade dysplastic nodules (DNs) and low-grade from high-grade hepatocellular carcinomas (HCCs) using gadoxetate disodium-enhanced MRI. MATERIALS AND METHODS A retrospective study of 149 hepatic nodules in 127 consecutive patients who(More)
PURPOSE The impact of familial clustering of hepatocellular carcinoma (HCC) in hepatitis B virus (HBV)-infected persons in a low HBV endemic area was investigated. METHODS Four hundred thirteen HBsAg-positive patients, 173 with HCC and 240 without HCC, were subgrouped into those with or without a family history of HCC and analyzed for risk factors(More)
The aim of this study was to determine the prognostic value of complete tumor encapsulation as visualized on magnetic resonance imaging (MRI) in patients with a solitary large hepatocellular carcinoma (HCC) beyond the Milan criteria for liver transplantation (LT). Between December 2000 and March 2011, 57 patients who had a solitary HCC exceeding 5 cm in(More)
Thailand has a high incidence of cholangiocarcinoma (CCA), particularly in the north and northeastern regions. Most CCA patients come at a late, unresectable stage and presently no optimal screening test for CCA has been established. We determined the prevalence of CCA in a remote northern village and explored if screening could lead to early detection and(More)
BACKGROUND AND AIM The performance of alpha-fetoprotein (AFP) in the detection of hepatocellular carcinoma (HCC) recurrence after radiofrequency ablation was analyzed. METHODS One hundred and forty-six solitary HCC lesions treated by radiofrequency ablation were evaluated. Using the AFP cutoff level at ≥ 20 ng/mL, tumors were categorized into AFP or(More)
To compare the amount of tissue contraction after microwave (MW) versus radiofrequency (RF) ablation of liver tumors. Seventy-five hepatic tumors in 65 patients who underwent percutaneous MW or RF ablations were included in this retrospective study. All patients underwent MRI within 6 months before the ablation and 24 h after the procedure. Two blinded(More)
