Hepatocellular carcinoma (HCC) is a common cause of cancer-related death, with incidence increasing worldwide. Unfortunately, the overall prognosis for patients with HCC is poor and many patients present with advanced stages of disease that preclude curative therapies. Diagnostic and interventional radiologists play a key role in the management of patients with HCC. Diagnostic radiologists can use contrast-enhanced computed tomography (CT), magnetic resonance imaging, and ultrasound to diagnose and stage HCC, without the need for pathologic confirmation, by following established criteria...

Hepatocellular carcinoma (HCC) is the most common primary liver cancer and a major public health problem worldwide. Hepatocarcinogenesis is a complex multistep process at molecular, cellular, and histologic levels with key alterations that can be revealed by noninvasive imaging modalities. Therefore, imaging techniques play pivotal roles in the detection, characterization, staging, surveillance, and prognosis evaluation of HCC. Currently, ultrasound is the first-line imaging modality for screening and surveillance purposes...

AIM: To evaluate the potential value of texture analysis (TA) based on contrast-enhanced magnetic resonance imaging (MRI) for predicting an early response of patients with hepatocellular carcinoma (HCC) who were treated with transcatheter arterial chemoembolisation (TACE) combined with high-intensity focused ultrasound (HIFU). MATERIALS AND METHODS: Patients with HCC (n=89) who underwent contrast-enhanced MRI at 1.5 T 1 week before and 1 week, 1 month, and 3 months after TACE/HIFU were included in this retrospective study...

The American College of Radiology (ACR) endorsed the Liver Imaging Reporting and Data System (LI-RADS) for standardized reporting and data collection of computed tomography (CT) and magnetic resonance (MR) imaging for hepatocellular carcinoma (HCC) in high-risk patients (liver cirrhosis). The LI-RADS imaging criteria are used to classify 'observations' from 'definitely benign' (LR-1) to 'definitely HCC' (LR-5) based on imaging criteria.Coincidently, the recent approval in the United States of a microbubble contrast agent for liver imaging (Lumason® , known as SonoVue® in Europe and elsewhere), LI-RADS...

BACKGROUND: Patients with cirrhosis are at high risk of hepatocellular carcinoma (HCC). The SEPT9 gene is a key regulator of cell division and tumor suppressor whose hypermethylation is associated with liver carcinogenesis. The primary aim of this study was to evaluate the diagnostic accuracy of a PCR-based assay for the analysis of SEPT9 promoter methylation in circulating cell-free DNA (mSEPT9) for diagnosing HCC among cirrhotic patients. METHODS: We report two phase II biomarker studies that included cirrhotic patients with or without HCC from France (initial study) and Germany (replication study)...

BACKGROUND: Hepatitis B virus (HBV) infection is common with major clinical consequences. In Asian Americans, the HBsAg carrier rate ranges from 2% to 16% which approximates the rates from their countries of origin. Similarly, HBV is the most important cause of cirrhosis, hepatocellular carcinoma (HCC) and liver related deaths in HBsAg positive Asians worldwide. AIM: To generate recommendations for the management of Asian Americans infected with HBV. METHODS: These guidelines are based on relevant data derived from medical reports on HBV from Asian countries as well as from studies in the HBsAg positive Asian Americans...

The aim of this study was to analyze the correlation between the quantitative parameters of contrast-enhancement ultrasound for primary hepatocellular carcinoma (HCC) and biological manifestations of tumor (Ki-67), and to explore the related risk factors of primary hepatocellular carcinoma, so as to provide the theoretical basis for the further study on contrast-enhancement ultrasound manifestations, clinical features and prognosis of HCC. The patients with HCC confirmed by operation or puncture were collected, and those with the background of liver cirrhosis and immunohistochemical staining for tumor sample sections were selected...

Objective: To retrospectively evaluate the safety and technical efficacy of percutaneous radiofrequency ablation (RFA) of surface hepatocellular carcinoma (HCC) in comparison to intraparenchymal HCC in cirrhotic patients. Materials and Methods: Surface lesions were defined as tumours located or reaching within 1cm of liver capsule including exophytic lesions. Seventy-four surface HCC including 21 exophytic in 58 patients (surface group) and 60 intraparenchymal HCC in 54 patients (intraparenchymal group) measuring up to 4 cm in maximum extent underwent percutaneous [ultrasound (US) or computed tomography-guided (CT-guided)] RFA...

AIM: To confirm whether cirrhosis is indispensable for the non-invasive diagnostic criteria for hepatocellular carcinoma (HCC) in hepatitis B virus (HBV)-endemic areas. METHODS: Between January 2014 and December 2014, a total of 409 patients with pathologically proven focal liver lesions who underwent contrast-enhanced ultrasound (CEUS) were recruited from our institution. Clinical liver cirrhosis, HBV/HCV infection and HCC-typical vascular pattern of the targeted lesion on CEUS were evaluated...

Hepatocellular carcinoma (HCC) is the fourth most common and the third most lethal cancer in China. An updated version of consensus-based recommendations on the management of HCC has been recently published by a multidisciplinary group of Chinese experts including liver surgeons, hepatic oncologists, radiologists and pathologists. Major changes have been made to the diagnostic criteria. In addition to dynamic multi-detector computed tomography (CT) and magnetic resonance imaging (MRI), gadoxetic acid-enhanced MRI and contrast-enhanced ultrasound (CEUS) are added to the diagnostic imaging tests...

A 47-year-old Japanese man was referred to hospital after the detection of a liver tumor. Dynamic computed tomography and gadolinium ethoxybenzyl diethylenetriaminepentaacetic acid (Gd-EOB-DTPA)-enhanced magnetic resonance imaging were consistent with a diagnosis of hepatocellular carcinoma (HCC). No perfusion defect was observed in the post-vascular phase of contrast-enhanced ultrasound (CEUS). Histopathological staining of the tumor cells was positive for antibodies against HMB-45 and cluster of differentiation (CD) 68, confirming the diagnosis of hepatic angiomyolipoma (HAML)...

BACKGROUND & AIMS: The use of contrast enhanced ultrasound (CEUS) for the diagnosis of hepatocellular carcinoma (HCC) in cirrhosis was questioned because of the risk of a false positive diagnosis in cases of cholangiocarcinoma. The American College of Radiology has recently released a scheme (CEUS Liver Imaging Reporting and Data System [LI-RADS®]) to classify lesions at risk of HCC investigated by CEUS. The aim of the present study was to validate this LI-RADS scheme for the diagnosis of HCC...
