Abstract Purpose Microwave ablation (MWA) and conventional transarterial chemoembolization (cTACE) are locoregional treatments commonly performed in very early, early and intermediate stages of ...hepatocellular carcinoma (HCC). Despite combined locoregional approaches have shown encouraging results in obtaining complete tumor necrosis, their application in a single session is poorly described. Our aim was to evaluate the safety and efficacy of single-session MWA and cTACE treatment in 5-cm HCCs and its influence on liver function. Materials and methods All 5-cm HCCs treated by MWA and cTACE performed in a single-session in our Interventional Radiology unit between January 2020 and December 2022 were retrospectively recorded and analyzed. Patients with poor or missing pre- and post-treatment imaging were excluded. Technical success, clinical success, and complications rate were examined as primary endpoints. Pre- and post-treatment liver function laboratory parameters were also evaluated. Results A total of 15 lesions (mean lesion diameter, 5.0 ± 1.4 cm) in 15 patients (11 men; mean age, 67.1 ± 8.9 years) were retrospectively evaluated. Technical and clinical success were 100% and 73%, respectively. Four (27%) cases of partial response and no cases of progressive or stable disease were recorded. AST and ALT values have found to be significantly higher in post-treatment laboratory tests. No other significant differences between pre- and post-treatment laboratory values were registered. AST and ALT pre- and post-treatment higher differences (ΔAST and ΔALT) were significantly associated with a lower clinical success rate. Conclusion MWA and cTACE single-session approach is safe and effective for 5-cm HCCs, without significant liver function impairment. A post-treatment increase in AST and ALT values may be a predictor for clinical failure.
Hepatitis E Virus is endemic in Europe with increasing numbers of cases in recent years, also in Italy where this phenomenon has hitherto been modest. The aim of this study was to document the ...clinical features/natural history of locally acquired hepatitis E in our territory and explore factors which determine adverse outcome.
Retrospective study of patients with locally-acquired HEV (hepatitis E virus) in Marche, Italy (2011–2019).
1189 patients were tested for HEV with 89 confirmed cases. 81 (6.8%) had locally acquired infection; 54 (66%) were male (mean age 55.5 years) and 32 (39.5%) had active co-morbidities. 41 cases were viraemic (all HEV-3 (HEV genotype 1,2,3,4)); acute infection was found in 79 and chronic infection in 2. Forty-five cases (55%) required admission to hospital, for a total of 785 days. 4 patients developed acute on-chronic liver failure, 6 developed acute kidney injury and 8 died: all had active comorbidities. Univariate analysis showed that bilirubin, INR, immunosuppression, cirrhosis and diabetes were associated with death. On multivariant analysis the only predictor of death was the presence of diabetes (p = 0.04).
Hepatitis E in Marche Italy is mostly locally acquired and caused by HEV-3 that impacts on the morbidity and mortality particularly for fragile patients.
Ulcerative Colitis (UC) and Crohn's Disease (CD) are chronic, progressive and disabling disorders characterized by a heterogeneous clinical course. Some years ago the main goal of the therapy was to ...achieve and maintain clinical remission, whereas at present the main goal of therapy is represented by the deep remission, characterized by sustained clinical remission, complete mucosal healing and normalization of serological markers of inflammation. In the last years new therapeutic approaches have been introduced which have led to a reduction in the mortality rate and have modified the natural history of Inflammatory Bowel Diseases (IBD). In addition, several prognostic factors have been identified which have allowed to better stratify the disease and to choose the most appropriate therapy for the single patient. Moreover, early treatment with immunosuppressive drugs and/or biologics has changed, at least in the short term, the course of the disease by reducing hospitalization rate and the need for surgery. Therefore, the development of biologic therapies has represented an important step in the treatment of IBD, since these drugs induce remission and response rates that are not achieved by other therapies. Since their use can result in significant adverse events that increase morbidity, patients must be aware of the risks associated with treatment and must be strictly monitored. Although treatment with biologic drugs is not successful in all patients and many of them lose clinical response, new therapies are currently under evaluation.
Nonalcoholic fatty liver disease (NAFLD) represents the hepatic manifestation of metabolic syndrome and may evolve into hepatocellular carcinoma (HCC). Only scanty clinical information is available ...on HCC in NAFLD. The aim of this multicenter observational prospective study was to assess the clinical features of patients with NAFLD‐related HCC (NAFLD‐HCC) and to compare them to those of hepatitis C virus (HCV)‐related HCC. A total of 756 patients with either NAFLD (145) or HCV‐related chronic liver disease (611) were enrolled in secondary care Italian centers. Survival was modeled according to clinical parameters, lead‐time bias, and propensity analysis. Compared to HCV, HCC in NAFLD patients had a larger volume, showed more often an infiltrative pattern, and was detected outside specific surveillance. Cirrhosis was present in only about 50% of NAFLD‐HCC patients, in contrast to the near totality of HCV‐HCC. Regardless of tumor stage, survival was significantly shorter (P = 0.017) in patients with NAFLD‐HCC, 25.5 months (95% confidence interval 21.9‐29.1), than in those with HCV‐HCC, 33.7 months (95% confidence interval 31.9‐35.4). To eliminate possible confounders, a propensity score analysis was performed, which showed no more significant difference between the two groups. Additionally, analysis of patients within Milan criteria submitted to curative treatments did not show any difference in survival between NAFLD‐HCC and HCV‐HCC (respectively, 38.6 versus 41.0 months, P = nonsignificant) Conclusions: NAFLD‐HCC is more often detected at a later tumor stage and could arise also in the absence of cirrhosis, but after patient matching, it has a similar survival rate compared to HCV infection; a future challenge will be to identify patients with NAFLD who require more stringent surveillance in order to offer the most timely and effective treatment.

Background & Aims The role of hepatic resection for hepatocellular carcinoma (HCC) in different Barcelona Clinic Liver Cancer (BCLC) stages is controversial. We aimed at measuring the survival ...benefit of resection vs. non-surgical-therapies in each BCLC stage. Methods Using the ITA.LI.CA database, we identified 2090 BCLC A, B, and C HCC patients observed between 2000 and 2012: 550 underwent resection, 1046 loco-regional therapy (LRT), and 494 best supportive care (BSC). A multivariate log-logistic model was chosen to predict median survival (MS) after resection vs. MS after LRT or BSC. The results were expressed as net survival benefit of resection: (MS resection – MS LRT)/MS BSC. Results After stratifying for BCLC stage, the median net survival benefit of resection over LRT was: BCLC 0 = 62% (40%, 82%), A = 45% (13%, 65%), B = 46% (9%, 76%), C = −16% (−55%, 33%). Model for end-stage liver disease (MELD) score >9, Child B class, and performance status (PST) = 2 were the main risk factors for liver resection. 1181 Child A patients (57%) with MELD ⩽9 and PST <2 had always a large positive net survival benefit of resection over LRT, independently of BCLC stage: BCLC 0 = 64% (44%, 85%), A = 59% (45%, 74%), B = 71% (52%, 90%), C = 56% (36%, 78%). Among the 909 (43%) patients with at least one risk factor (MELD >9 or PST = 2 or Child B class), resection did not prove any survival benefit over LRT. Conclusions Resection could result in survival benefit over LRT for HCC patients regardless of their BCLC stage, provided that liver dysfunction (Child B or MELD >9) and PST >1 are absent.
Background & Aims Lead-time is the time by which diagnosis is anticipated by screening/surveillance with respect to the symptomatic detection of a disease. Any screening program, including ...surveillance for hepatocellular carcinoma (HCC), is subject to lead-time bias. Data regarding lead-time for HCC are lacking. Aims of the present study were to calculate lead-time and to assess its impact on the benefit obtainable from the surveillance of cirrhotic patients. Methods One-thousand three-hundred and eighty Child–Pugh class A/B patients from the ITA.LI.CA database, in whom HCC was detected during semiannual surveillance (n = 850), annual surveillance (n = 234) or when patients came when symptomatic (n = 296), were selected. Lead-time was estimated by means of appropriate formulas and Monte Carlo simulation, including 1000 patients for each arm. Results The 5-year overall survival after HCC diagnosis was 32.7% in semiannually surveilled patients, 25.2% in annually surveilled patients, and 12.2% in symptomatic patients ( p <0.001). In a 10-year follow-up perspective, the median lead-time calculated for all surveilled patients was 6.5 months (7.2 for semiannual and 4.1 for annual surveillance). Lead-time bias accounted for most of the surveillance benefit until the third year of follow-up after HCC diagnosis. However, even after lead-time adjustment, semiannual surveillance maintained a survival benefit over symptomatic diagnosis (number of patients needed to screen = 13), as did annual surveillance (18 patients). Conclusions Lead-time bias is the main determinant of the short-term benefit provided by surveillance for HCC, but this benefit becomes factual in a long-term perspective, confirming the clinical utility of an anticipated diagnosis of HCC.
Background & Aims
Chronic hepatitis D virus (HDV) often leads to end‐stage liver disease and hepatocellular carcinoma (HCC). Comprehensive data pertaining to large populations with HDV and HCC are ...missing, therefore we sought to assess the characteristics, management, and outcome of these patients, comparing them to patients with hepatitis B virus (HBV) infection.
Methods
We analysed the Italian Liver Cancer database focusing on patients with positivity for HBV surface antigen and anti‐HDV antibodies (HBV/HDV, n = 107) and patients with HBV infection alone (n = 588). Clinical and oncological characteristics, treatment, and survival were compared in the two groups.
Results
Patients with HBV/HDV had worse liver function Model for End‐stage Liver Disease score: 11 vs. 9, p < .0001; Child‐Turcotte‐Pugh score: 7 vs. 5, p < .0001 than patients with HBV. HCC was more frequently diagnosed during surveillance (72.9% vs. 52.4%, p = .0002), and the oncological stage was more frequently Milan‐in (67.3% vs. 52.7%, p = .005) in patients with HBV/HDV. Liver transplantation was more frequently performed in HBV/HDV than in HBV patients (36.4% vs. 9.5%), while the opposite was observed for resection (8.4% vs. 20.1%, p < .0001), and in a competing risk analysis, HBV/HDV patients had a higher probability of receiving transplantation, independently of liver function and oncological stage. A trend towards longer survival was observed in patients with HBV/HDV (50.4 vs. 44.4 months, p = .106).
Conclusions
In patients with HBV/HDV, HCC is diagnosed more frequently during surveillance, resulting in a less advanced cancer stage in patients with more deranged liver function than HBV alone. Patients with HBV/HDV have a heightened benefit from liver transplantation, positively influencing survival.
Summary
Background
Hepatitis C virus (HCV) and alcohol abuse are the main risk factors for hepatocellular carcinoma (HCC) in Western countries.
Aim
To investigate the role of alcoholic aetiology on ...clinical presentation, treatment and outcome of HCC as well as on each Barcelona Clinic Liver Cancer (BCLC) stage, as compared to HCV‐related HCCs.
Methods
A total of 1642 HCV and 573 alcoholic patients from the Italian Liver Cancer (ITA.LI.CA) database, diagnosed with HCC between January 2000 and December 2012 were compared for age, gender, type of diagnosis, tumour burden, portal vein thrombosis (PVT), oesophageal varices, liver function tests, alpha‐fetoprotein, BCLC, treatment and survival. Aetiology was tested as predictor of survival in multivariate Cox regression models and according to HCC stages.
Results
Cirrhosis was present in 96% of cases in both groups. Alcoholic patients were younger, more likely male, with HCC diagnosed outside surveillance, in intermediate/terminal BCLC stage and had worse liver function. After adjustment for the lead‐time, median (95% CI) overall survival (OS) was 27.4 months (21.5–33.2) in alcoholic and 33.6 months (30.7–36.5) in HCV patients (P = 0.021). The prognostic role of aetiology disappeared when survival was assessed in each BCLC stage and in the Cox regression multivariate models.
Conclusions
Alcoholic aetiology affects survival of HCC patients through its negative effects on secondary prevention and cancer presentation but not through a greater cancer aggressiveness or worse treatment result. In fact, survival adjusted for confounding factors was similar in alcoholic and HCV patients.
