Characteristics and survival of patients with primary biliary cholangitis and hepatocellular carcinoma
Background: Comprehensive and contemporary data pertaining large populations of patients with Primary Biliary Cholangitis (PBC) and hepatocellular carcinoma (HCC) are missing. Aim: To describe main characteristics and outcome of PBC patients with HCC diagnosed in the new millennium. Methods: Analysing the Italian Liver Cancer registry we identified 80 PBC patients with HCC diagnosed after the year 2000, and described their clinical characteristics, access to treatment and survival. Results: Median age of patients was 71 years and 50.0% were males. Cirrhosis was present in 86.3% of patients, being well-compensated in 58.0%. Median HCC diameter was smaller in patients under surveillance (2.6 …
What is in our seas? Assessing anthropogenic litter on the seafloor of the central Mediterranean Sea
Abstract Abundance, composition, and distribution of macro-litter found on the seafloor of the Strait of Sicily between 10 and 800 m depth has been studied using data collected by bottom trawl surveys MEDITS from 2015 to 2019. Three waste categories based on the items use were considered: single-use, fishing-related and generic-use. Over 600 sampling sites, just 14% of these were litter-free. The five-years average density of seafloor litter was 79.6 items/km2 and ranged between 46.8 in 2019 and 118.1 items/km2 in 2015. The predominant waste type was plastic (58% of all items). Regardless of material type, single-use items were a dominant (60% of items) and widespread (79% of hauls) fractio…
How does climate change affect a fishable resource? The case of the royal sea cucumber (Parastichopus regalis) in the central Mediterranean Sea
Holothurians or sea cucumbers are key organisms in marine ecosystems that, by ingesting large quantities of sediments, provide important ecosystem services. Among them, Parastichopus regalis (Cuvier, 1817) is one of the living sea cucumbers in the Mediterranean actively fished for human consumption mainly in Spain, where it is considered a gastronomic delicacy. In the Strait of Sicily (central Mediterranean Sea), this species is not exploited for commercial use even if it is used as bait by longline fishery. P. regalis is frequently caught by bottom trawling and discarded at sea by fishers after catch, and because of its capacity to resist air exposition (at least in cold months), it is rea…
Potential feasibility of atezolizumab-bevacizumab therapy in patients with hepatocellular carcinoma treated with tyrosine-kinase inhibitors
Background: The combination of atezolizumab-bevacizumab has been proven to be superior to sorafenib for the treatment of unresectable hepatocellular carcinoma not amenable to locoregional treatments, be-coming the standard of care of systemic therapy.Aim: This study aimed at assessing real-world feasibility of atezolizumab-bevacizumab in patients treated with tyrosine-kinase inhibitors.Methods: Among 1447 patients treated with tyrosine-kinase inhibitors from January 2010 to December 2020, we assessed the percentage of those potentially eligible to atezolizumab-bevacizumab (according to IMbrave-150 trial criteria), and the overall survival of eligible and non-eligible patients.Results: 422 (…
Recalibrating survival prediction among patients receiving trans‐arterial chemoembolization for hepatocellular carcinoma
Background & Aims The Pre-TACE-Predict model was devised to assess prognosis of patients treated with trans-arterial chemoembolization (TACE) for hepatocellular carcinoma (HCC). However, before entering clinical practice, a model should demonstrate that it performs a useful role. Methods We performed an independent external validation of the Pre-TACE model in a cohort that differs in setting and time period from the one that generated the original model. Data from 826 patients treated with TACE for naïve HCC (2008-2018) were used to assess calibration and discrimination of the Pre-TACE-Predict model. Results The four risk-categories identified by the Pre-TACE-Predict model had gradient …
Monofocal hepatocellular carcinoma: How much does size matter?
Background & Aims: According to the Barcelona Clinic Liver Cancer (BCLC) staging system, monofocal hepatocellular carcinoma (HCC) is classified as early (BCLC A) irrespective of its size, even though controversies still exist regarding staging and treatment of large tumours. We aimed at evaluating the appropriate staging and treatment for large (>5 cm) monofocal (HCC). Methods: From the Italian Liver Cancer database, we selected 924 patients with small early monofocal HCC (2-5 cm; SEM-HCC), 163 patients with larger tumours (>5 cm; LEM-HCC) and 1048 intermediate stage patients (BCLC B). Results: LEM-HCC patients had a worse overall survival (OS) than SEM-HCC (31.0 vs 49.0 months; P…
Material deprivation affects the management and clinical outcome of hepatocellular carcinoma in a high-resource environment
Abstract Aim This study investigated how material deprivation in Italy influences the stage of hepatocellular carcinoma (HCC) at diagnosis and the chance of cure. Methods 4114 patients from the Italian Liver Cancer database consecutively diagnosed with HCC between January 2008 and December 2018 were analysed about severe material deprivation (SMD) rate tertiles of the region of birth and region of managing hospitals, according to the European Statistics on Income and Living Conditions. The main outcomes were HCC diagnosis modalities (during or outside surveillance), treatment adoption and overall survival. Results In more deprived regions, HCC was more frequently diagnosed during surveillan…
Surveillance for hepatocellular carcinoma with a 3-months interval in “extremely high-risk” patients does not further improve survival
Abstract Background An enhanced surveillance schedule has been proposed for cirrhotics with viral etiology, who are considered at extremely high-risk of hepatocellular carcinoma (HCC). Aims We compared the 3- and 6-months surveillance interval, evaluating cancer stage at diagnosis and patient survival. Methods Data of 777 HBV and HCV cirrhotic patients with HCC diagnosed under a 3-months (n = 109, 3MS group) or a 6-months (n = 668, 6MS group) surveillance were retrieved from the Italian Liver Cancer database. Survival in the 3MS group was considered as observed and adjusted for lead-time bias, and survival analysis was repeated after a propensity score matching. Results The 3-months surveil…
The increasing temperature as driving force for spatial distribution patterns of Parapenaeus longirostris (Lucas 1846) in the Strait of Sicily (Central Mediterranean Sea)
Abstract The deep-water rose shrimp Parapenaeus longirostris (DPS), a demersal decapod representing the most important component of crustacean landings in the Mediterranean Sea, has been suggested as a species that may exhibit temperature-driven changes in the spatio-temporal dynamics. Considering that Mediterranean waters are warming up faster than oceans, understanding the relationships of DPS populations with temperature variations and the related changes in spatial patterns is absolutely key for its management. Using a long-term dataset covering 13-years from scientific surveys (International Bottom Trawl-Surveys in the Mediterranean, MEDITS; Italian national trawl surveys, GRUND) in th…
