Background & Aims: The incidence of metabolic syndrome-related hepatocellular carcinoma (MS-HCC) is increasing worldwide. High resection risks are anticipated because of underlying steatohepatitis, but long-term results are unknown. To clarify the outcomes following liver resection in patients with MS-HCC and to compare the outcomes of MS-HCC to HCV-related HCC (HCV-HCC)., Methods: All the consecutive patients undergoing liver resection for HCC in six high-volume HPB units between 2000 and 2012 were retrospectively considered. The patients with MS-HCC were identified and matched one-to-one with HCV-HCC patients without metabolic syndrome. Matching was based on age, cirrhosis, Child-Pugh class, portal hypertension, HCC number and diameter and liver resection extension., Results: Among 1563 patients undergoing liver resection for HCC in the study period, 96 (6.1%) had MS-HCC. They were matched with 96 HCV-HCC patients. All patients were Child-Pugh class A, 22.9% had cirrhosis. Forty-one patients per group (42.7%) required major hepatectomy. The MS-HCC group had a higher prevalence of steatohepatitis (25.0% vs. 9.4%, p=0.004). Operative mortality was 2.1% (1 MS-HCC, 3 HCV-HCC, p=0.621). Morbidity and liver failure rates were similar between the two groups. In the multivariate analysis, cirrhosis, major hepatectomy, and MELD >8, but not steatohepatitis, impacted severe morbidity and liver failure rates. The MS-HCC group had better 5-year overall survival (65.6% vs. 61.4%, p=0.031) and recurrence-free survival (37.0% vs. 27.5%, p=0.077). Independent negative prognostic factors were HCV-HCC, multiple HCC, microvascular invasion, and satellite nodules., Conclusions: Liver resection is safe for MS-HCC, as for HCV-HCC. Cirrhosis, but not steatohepatitis, affects short-term outcomes. MS-HCC is associated with excellent long-term outcomes, better than HCV-HCC., (Copyright © 2015 European Association for the Study of the Liver. Published by Elsevier B.V. All rights reserved.)

Background & Aims: The aim of this study was to compare liver resection and radiofrequency ablation in patients with single hepatocellular carcinoma ≤3 cm and compensated cirrhosis., Methods: The study involved 544 Child-Pugh A cirrhotic patients (246 in the resection group and 298 in the radiofrequency group) observed in 15 Italian centers. Overall survival and tumor recurrence rates were analyzed using the Kaplan Meier method before and after propensity score matching. Cox regression models were used to identify factors associated with overall survival and tumor recurrence., Results: Two cases of perioperative mortality were observed in the resection group and the rate of major complications was 4.5% in the resection group and 2.0% in the radiofrequency group (p=0.101). Four-year overall survival rates were 74.4% in the resection group and 66.2% in the radiofrequency group (p=0.353). Four-year cumulative HCC recurrence rates were 56% in the resection group and 57.1% in the radiofrequency group (p=0.765). Local tumor progression was detected in 20.5% of ablated patients and in one resected patient (p<0.001). After propensity score matching, both survival and tumor recurrence were still not significantly different although a trend towards lower recurrence was observed in resected patients. Older age and higher alpha-fetoprotein levels were independent predictors of poor overall survival while older age and higher alanine-aminotransferase levels resulted to be independent factors associated with higher recurrence rate., Conclusions: In spite of a higher rate of local tumor progression, radiofrequency ablation can provide results comparable to liver resection in the treatment of single hepatocellular carcinoma ≤3 cm occurring in compensated cirrhosis., (Copyright © 2013 European Association for the Study of the Liver.

Fine needle aspiration or biopsy is used for cytologic diagnosis of many intra-abdominal tumors including focal liver lesions. The incidence of needle tract seeding is quite low. In this paper the first case of cutaneous seeding after percutaneous fine needle aspiration of liver metastasis is reported in a case of colon cancer. We suggest using this method for cytologic diagnosis in hepatic tumors when surgical resection is not possible and when patients will be treated with invasive therapies and to avoid fine needle aspiration biopsy in patients undergoing surgical resection or when there is a confident diagnosis of HCC by non-invasive procedures.
