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...

Non-alcoholic fatty liver disease (NAFLD) is considered the hepatic manifestation of metabolic syndrome (MS) [1], and it is defined by the presence of steatosis in >5% of hepatocytes, according to histological analysis or detected by specific proton density fat fraction obtained MRI. The term NAFLD covers two pathologically distinct conditions: non-alcoholic fatty liver (NAFL) and non-alcoholic steatohepatitis (NASH), which can have similar clinical presentation, but with different prognosis. Both conditions can lastly lead to the development of cirrhosis...

BACKGROUND: Metastatic cardiac tumors may cause different symptoms including angina, symptoms of heart failure and/or arrhythmia. In patients with concomitant coronary artery disease, it may be difficult to distinguish between angina caused by metastases to the heart, for example, by stealing perfusion from the coronary arteries, and angina caused by coronary stenosis. Identifying the origin of the symptoms is, however, essential for designing appropriate surgical strategies. CASE PRESENTATION: A 69-year-old male with multifocal recurrence of a hepatocellular carcinoma (HCC) presented with increasing ventricular arrhythmia and angina several weeks after posterior myocardial infarction and PCI of the RCA culprit lesion during which two further lesions present in the distal RCX and a posterolateral branch, and a chronically occluded LAD had not been addressed...

Microvascular invasion (MVI) is rarely diagnosed preoperatively in hepatocellular carcinoma (HCC). The aim of this meta-analysis is to assess the diagnostic power of a non-smooth tumor margin on preoperative imaging for MVI. We performed a literature search using the PubMed, Embase and Cochrane Library databases, and 11 studies were included involving 618 MVI-positive cases and 1030 MVI-negative cases. Considerable heterogeneity was found, and was indicated to be attributable to the mean patient ages in the included studies...

Magnetic nanoparticles (NPs) have emerged as a promising tool for suicide gene therapy. However, the separate delivery of the suicide gene and prodrug in current systems limits their clinical translation. Therefore, improving magnetically mediated suicide gene therapy by exploring higher performance magnetic NP-based hybrid nanoplatforms is an important challenge. In the current study, shape-controlled magnetic mesoporous silica nanoparticles (M-MSNs) were prepared, and their performance in magnetic resonance imaging (MRI)-guided, magnetically targeted and hyperthermia-enhanced suicide gene therapy of hepatocellular carcinoma (HCC) was investigated...
