RESUMO
BACKGROUND: Recent innovations in the field of liver transplantation have led to a wealth of new treatment regimes, with potential impact on the onset of de novo malignancies (DNM). The aim of this multicenter cohort study was to provide contemporary figures for the cumulative incidences of solid and hematological DNM after liver transplantation. METHODS: We designed a retrospective cohort study including patients undergoing LT between 2000 and 2015 in three Italian transplant centers. Cumulative incidence was calculated by Kaplan-Meyer analysis. RESULTS: The study included 789 LT patients with a median follow-up of 81 months (IQR: 38-124). The cumulative incidence of non-cutaneous DNM was 6.2% at 5-years, 11.6% at 10-years and 16.3% at 15-years. Post-Transplant Lymphoproliferative Disorders (PTLD) were demonstrated to have a cumulative incidence of 1.0% at 5-years, 1.6% at 10-years and 2.2% at 15-years. Solid Organ Tumors (SOT) demonstrated higher cumulative incidences - 5.3% at 5-years, 10.3% at 10-years and 14.4% at 15-years. The most frequently observed classifications of SOT were lung (rate 1.0% at 5-years, 2.5% at 10-years) and head & neck tumors (rate 1.3% at 5-years, 1.9% at 10-years). CONCLUSIONS: Lung tumors and head & neck tumors are the most frequently observed SOT after LT.

INTRODUCTION AND AIM: Cirrhotic patients with hepatitis C virus genotype 3 infection show unsatisfactory outcomes after 12 weeks' treatment with direct antiviral agents. The National Italian Drug Agency allows 24 weeks of therapy in difficult-to-treat patients, including genotype 3 cirrhotics. Aim of this study was to evaluate efficacy and safety of a 24-week course of sofosbuvir plus daclatasvir±ribavirin in this population. MATERIALS AND METHODS: 106 consecutive cirrhotics (70.8% males, mean age 55.3±7.6 years) in 8 tertiary hepatology centers received sofosbuvir plus daclatasvir for 24 weeks. Ribavirin was administered in 85 (80.2%) based expected tolerability, at a mean dose of 964±202mg/day. Baseline Child-Pugh class was A 91.5%, B 6.6%, C 1.9%; mean baseline MELD was 8.5±2.7. RESULTS: All patients completed 12-week follow-up post-treatment, and 104 (98.1%) obtained sustained virological response (100% in ribavirin -treated patients vs. 90.4% without ribavirin; p=0.04). No worsening in renal and liver function was observed, no serious adverse events occurred. Two virological failures showed resistance associated variants (Y93H and S282T). CONCLUSION: An extended 24-week treatment with sofosbuvir plus daclatasvir+ribavirin obtained 100% efficacy in genotype 3 hepatitis C cirrhosis, with very limited side effects. The role of ribavirin seems crucial in this setting and should be administered if clinically feasible.
