ABSTRACT
BACKGROUND & AIMS: Information on safety and efficacy of systemic treatment in patients with hepatocellular carcinoma (HCC) under dialysis are limited due to patient exclusion from clinical trials. Thus, we aimed to evaluate the rate, prevalence, tolerability, and outcome of sorafenib in this population. METHODS: We report a multicenter study comprising patients from Latin America and Europe. Patients treated with sorafenib were enrolled; demographics, dose modifications, adverse events (AEs), treatment duration, and outcome of patients undergoing dialysis were recorded. RESULTS: As of March 2018, 6156 HCC patients were treated in 44 centres and 22 patients were concomitantly under dialysis (0.36%). The median age was 65.5 years, 40.9% had hepatitis C, 75% had Child-Pugh A, and 85% were Barcelona Clinic Liver Cancer-C. The median time to first dose modification, treatment duration and overall survival rate were 2.4 months (interquartile ranges [IQR], 0.8-3.8), 10.8 months (IQR, 4.5-16.9), and 17.5 months (95% CI, 7.2-24.5), respectively. Seventeen patients required at least 1 dose modification. The main causes of first dose modification were asthenia/worsening of Eastern Cooperative Oncology Group-Performance Status and diarrhoea. At the time of death or last follow-up, four patients were still on treatment and 18 had discontinued sorafenib: 14 were due to tumour progression, 2 were sorafenib-related, and 2 were non-sorafenib-related AE. CONCLUSIONS: The outcomes observed in this cohort seem comparable to those in the non-dialysis population. Thus, to the best of our knowledge, this is the largest and most informative dataset regarding systemic treatment outcomes in HCC patients undergoing dialysis.

BACKGROUND: Antiviral therapy (AVT) may improve liver histology in patients with advanced viral hepatitis but its effect on portal pressure remains unknown. AIM: This study was aimed to evaluate the influence of antiviral therapy (AVT) on hepatic venous pressure gradient (HVPG) in hepatitis C virus infected patients with portal hypertension. METHODS: Twenty compensated patients with chronic hepatitis C, fibrosis stage 3 or 4 and HVPG > 5 mmHg received PEG-IFN alpha2b plus ribavirin. Every patient underwent liver biopsy and portal pressure measurements before and immediately after AT. Biopsies were evaluated according to METAVIR score. RESULTS: HVPG significantly dropped in all but one treated patient, with a mean (SD) reduction of 28.2 (12)%[13.8 (5.6) Vs. 10.2 (3.8) mmHg, p = 0.005]. The percentage of HVPG decrease was significantly greater in patients who achieved a virological end of treatment response [26.2 (12.5)% Vs. 12.7 (8.5)%, p = 0.05] and in those with a decrease of at least 2 points in the grade of inflammation [35.7 (4.5)% Vs. 22.1 (9.5)%, p = 0.015]. Nine out of 11 patients with baseline HVPG > or = 12 mmHg showed a decrease greater than 20% (3/11) or under the 12 mmHg threshold (6/11). CONCLUSIONS: AVT reduces HVPG in compensated patients with advanced hepatitis C (fibrosis stage 3 or 4) and portal hypertension.
