ABSTRACT

Hepatocellular carcinoma (HCC) is one of the most common cancers in the world. A careful multidisciplinary assessment of tumor characteristics, liver function and physical status is required for proper therapeutic management. In recent years, several studies have supported the feasibility and benefit of combined therapy in the treatment of single large HCC, defined as those exceeding 3 cm in size. We present a case of combined treatment using radiofrequency ablation followed by trans-arterial chemoembolization with radiopaque embolic beads. The aim of this technical report was to describe the radiologic findings during combined radiofrequency ablation and radiopaque bead embolization, pointing out the differences and the potential advantages of using radiopaque beads compared with non-radiopaque beads. Furthermore, it is also the first report on using radiopaque beads in combined treatment for HCC.

ABSTRACT

Adult-type hypolactasia is a widespread condition throughout the world, causing lactose malabsorption. Several studies suggested that the identification of C/T-13910 and G/A-22018 mutations, located upstream the gene encoding the lactase-phlorizin hydrolase (LPH), is a useful tool for the differential diagnosis of hypolactasia. We evaluated the frequencies of C/T-13910 and G/A-22018 variants in a central-south Italian population and the usefulness of lactase deficiency genetic testing in the clinic practice. The genomic DNA of 1426 patients and 1000 healthy controls from central-south Italy was isolated from peripheral whole blood and genotyped for the C/T-13910 and G/A-22018 polymorphisms by high-resolution melting analysis (HRMA) and sequencing. The frequencies of genotypes in the 1426 patients analysed were as follows: 1077 CC/GG (75.5%), 287 CT/GA (20.1%), 24 TT/AA (1.7%), 38 CC/GA (2.7%). Only 64 out of 1426 (4.5%) performed also L-BHT test, 29 of which were negative for L-BHT also in presence of different genotypes. Among the 35 individuals with L-BHT positive, 34 were CC/GG and only one CT/GA. Although lactose genetic test is a good predictor of persistence/non-persistence lactase in specific population, its use in the central-south Italy population should be limited given the high prevalence of the CCGG diplotype in normal individuals.

ABSTRACT

AIM: To investigate differences in tolerability and response to treatment in compensated cirrhotic patients affected by hepatitis C virus (HCV) infection before and after liver transplantation. METHODS: Forty-three HCV non-liver transplanted (LT) cirrhotics (mean age 55 ± 8 years, 65.1% male, Child-Pugh-A, genotype 1-4: 65.1%, 2-3: 34.9%) and 17 LT recipients with recurrent HCV-related cirrhosis (mean age 57 ± 9 years, 88.2% male, Child-Pugh-A, genotype 1-4: 76.5%, 2-3: 23.5%) were included in the analysis from retrospective series. All patients received recombinant or pegylated interferon plus ribavirin at a standard dose and duration. Adverse events were recorded and classified according to the Common Terminology Criteria for Adverse Events. The mean duration of follow-up was of 4.3 ± 1.8 years after the end of the treatment. RESULTS: An early virological response (EVR) was achieved in 30/43 (69.8%) non-LT and in 8/17 (47.1%) LT cirrhotics, a sustained virological response (SVR) in 18/43 (41.9%) and 5/17 (29.4 %), respectively. No statistical difference was observed in EVR and SVR rates between the two groups. Among HCV non-LT cirrhotics, 6/43 (13.9%) discontinued the treatment prematurely, 11.6% of them receiving ≤ 80% of treatment; 8/17 (47%) LT cirrhotics withdrew the treatment, 35.2% of them receiving ≤ 80% of treatment. If compared with LT-ones (P = 0.015), an higher risk of treatment discontinuation could affect LT cirrhotics, who undergo more frequently ≤ 80% of treatment (P = 0.05). None of the non-LT cirrhotics died after the end of the treatment. With no regards to the achievement of SVR, LT cirrhotic patients showed a reduced survival in respect to non-LT ones (87% at 1 year, 76% at 3 and 5 years after the end of treatment). CONCLUSION: HCV antiviral treatment is equally effective in compensated cirrhotics both before and after LT, which patients show a higher risk of premature treatment withdrawal and a reduced survival, independently of the achievement of SVR.
