Abstract
Hepatocellular cancer ranks fifth among cancers and is related to chronic viral hepatitis, alcohol abuse, steatohepatitis and liver autoimmunity. Surgical resection and orthotopic liver transplantation have curative potential, but fewer than 20% of patients are suitable candidates. Interventional treatments are offered to the vast majority of patients. Radiofrequency (RFA) and microwave ablation (MWA) are among the therapeutic modalities, with similar indications which include the presence of up to three lesions, smaller than 3 cm in size, and the absence of extrahepatic disease. The therapeutic effect of both methods relies on thermal injury, but MWA uses an electromagnetic field as opposed to electrical current used in RFA. Unlike MWA, the effect of RFA is partially limited by the heat-sink effect and increased impedance of the ablated tissue. Compared with RFA, MWA attains a more predictable ablation zone, permits simultaneous treatment of multiple lesions, and achieves larger coagulation volumes in a shorter procedural time. Major complications of both methods are comparable and infrequent (approximately 2%-3%), and they include haemorrhage, infection/abscess, visceral organ injury, liver failure, and pneumothorax. RFA may incur the additional complication of skin burns. Nevertheless, there is no compelling evidence for differences in clinical outcomes, including local recurrence rates and survival.

Abstract
The role of fluorine-18-fluorodeoxygluose positron emission tomography/computed tomography ((18)F-FDG PET/CT) in hepatocellular carcinoma (HCC) has not been firmly established yet and its sensitivity has been reported to be in the range of 40-60 %. Because of this relatively low sensitivity alternative tracers have been proposed. The aim of our review is to analyse the literature data on the diagnostic role of (18)F/(11)C-choline PET/CT in the evaluation of HCC. A comprehensive computer literature search of PubMed/MEDLINE, Embase and Scopus databases was conducted to find relevant published articles about the role of whole-body (18)F-choline or (11)C-choline PET or PET/CT in patients with HCC. Furthermore, a meta-analysis about the detection rate of this method in HCC was performed. Six articles were included in this systematic review and discussed. The meta-analysis of five out of six articles showed a DR of 84 % (95 % CI 79-89 %). The DR increased when poorly differentiated HCC was excluded from the analysis. Radiolabelled choline PET or PET/CT could be a valuable tool in detecting HCC and it is better than (18)F-FDG PET/CT, especially in well to moderately differentiated lesions; on the other hand, poorly differentiated and higher-stage HCC could be better evaluated with (18)F-FDG and dual tracer imaging should be considered and could be potentially useful to increase accuracy.

Role of ¹⁸F-FDG PET CT as an independent prognostic indicator in patients with hepatocellular carcinoma. Nucl Med Commun 2014; 34:749-57.

Abstract
OBJECTIVES The aim of the study was to evaluate the role of F-fluorodeoxyglucose PET computed tomography (F-FDG PET CT) as an independent prognostic indicator in patients with hepatocellular carcinoma (HCC). MATERIALS AND METHODS PET contrast-enhanced CT scans of 100 consecutive patients with HCC were reviewed retrospectively. Patients were asked to fast for 6 h before the study and blood glucose levels were monitored and ensured to be less than 200 mg/dl before injection of F-FDG. After administering the F-FDG injection (370-550 MBq) patients were instructed to rest comfortably for 45-60 min. All images were acquired using a dedicated GE Discovery PET/CT scanner. The PET CT scans of all the patients were reported separately by two nuclear medicine physicians. A stage-wise analysis of the compiled data was carried out. Lesions that showed standardized uptake values greater than background activity (activity in adjacent normal liver tissue) were defined as having increased F-FDG uptake. Pearson's χ -test or the Kruskal-Wallis test was used to assess statistical significance. A P value less than 0.05 was taken as significant. RESULTS In this retrospective study of 100 HCC patients, a radiologically higher-stage disease was found more commonly in patients with F-FDG-avid primary tumors (P<0.001), whereas a lower-stage disease was found in patients with non-F-FDG-avid primary tumors. The non-F-FDG-avid tumors also showed lower incidence of metastatic disease and portal vein thrombosis (P<0.001). The histopathological findings of the patients who underwent liver transplantation demonstrated that a higher-grade tumor was more common in the F-FDG-avid tumor group than in the non-F-FDG-avid tumor group (P<0.05). CONCLUSION An F-FDG PET CT scan can be used not only for staging but also as a tool for preoperative prediction of cellular differentiation in patients with HCC. The F-FDG uptake seen on a PET scan can serve as a molecular signature for management decisions and can be used as an independent and significant prognostic factor in patients with HCC.

Abstract
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 transplantation, only 20% of HCCs are surgically treatable. In those patients who are not eligible for surgical treatment, interventional therapies such as transcatheter arterial chemoembolization (TACE), percutaneous ethanol injection (PEI), radio-frequency ablation (RFA), percutaneous microwave coagulation therapy (PMC), laser ablation or cryoablation, and acetic acid injection are indicated. In this paper, we aimed to review the evidence regarding imaging modalities and therapeutic interventions of HCC.

Abstract
Hepatocellular carcinoma (HCC) is the fifth most common malignancy in the world, responsible for 500,000 deaths globally every year. Although HCC is a slow-growing tumor, it is often rapidly fatal because it is usually not discovered until the disease is advanced. HCC occurs primarily in individuals with cirrhosis, a condition that increases the risk of performing potentially curative surgical therapy. Over the last 2 decades, however, the safety of surgical resections has greatly improved because of advances in radiologic assessment, patient selection, and perioperative care. As such, the operative mortality rate for hepatectomy has decreased from the 10%-20% level seen in the 1980s to less than 5% today. The ultimate goal of treatment of HCC is to prolong the quality of life by eradicating the malignancy while preserving hepatic function. For treatment with a curative intent, the gold standard remains surgical resection, by either partial hepatectomy or total hepatectomy followed by liver transplantation. Resectability and choice of procedure depend on many factors, including baseline liver function, absence of extrahepatic metastases, size of residual liver, availability of resources including liver graft, and expertise of the surgical team. Patients without cirrhosis can tolerate extensive resections, and partial hepatectomy should be considered first. For Child class B and C patients with a small HCC, liver transplantation offers the best results, whereas partial liver resection is indicated in patients with well-compensated cirrhosis. Living donor liver transplantation should be considered using the same criteria as that used for cadaveric transplantation.
