RESUMO
PURPOSE: Single large hepatocellular carcinoma >5cm (SLHCC) traditionally requires a major liver resection. Minor resections are often performed with the goal to reduce morbidity and mortality. Aim of the study was to establish if a major resection should be considered the best treatment for SLHCC or a more limited resection should be preferred. METHODS: A multicenter retrospective analysis of the HE.RC.O.LE.S. Group register was performed. All collected patients with surgically treated SLHCC were divided in 5 groups of treatment (major hepatectomy, sectorectomy, left lateral sectionectomy, segmentectomy, non-anatomical resection) and compared for baseline characteristics, short and long-term results. A propensity-score weighted analysis was performed. RESULTS: 535 patients were enrolled in the study. Major resection was associated with significantly increased major complications compared to left lateral sectionanectomy, segmentectomy and non-anatomical resection (all p<0.05) and borderline significant increased major complications compared to sectorectomy (p=0.08). Left lateral sectionectomy showed better overall survival compared to major resection (p=0.02), while other groups of treatment resulted similar to major hepatectomy group for the same item. Absence of oncological benefit after major resection and similar outcomes among the 5 groups of treatment was confirmed even in the sub-population excluding patients with macrovascular invasion. CONCLUSION: Major resection was associated to increased major post-operative morbidity without long-term survival benefit; when technically feasible and oncologically adequate, minor resections should be preferred for the surgical treatment of SLHCC.

OBJECTIVE: To evaluate the effect of a liver transplantation (LT) program on the outcomes of resectable hepatocellular carcinoma (HCC). BACKGROUND: Surgical treatment of HCC includes both hepatic resection (HR) and LT. However, the presence of cirrhosis and the possibility of recurrence make the management of this disease complex and probably different according to the presence of a LT program. METHODS: Patients undergoing HR for HCC between January 2005 and December 2019 were identified from a national database of HCC. The main study outcomes were major surgical complications according to the Comprehensive Complication Index, posthepatectomy liver failure (PHLF), 90-day mortality, overall survival, and disease-free survival. Secondary outcomes were salvage liver transplantation (SLT) and postrecurrence survival. RESULTS: A total of 3202 patients were included from 25 hospitals over the study period. Three of 25 (12%) had an LT program. The presence of an LT program within a center was associated with a reduced probability of PHLF (odds ratio=0.38) but not with overall survival and disease-free survival. There was an increased probability of SLT when HR was performed in a transplant hospital (odds ratio=12.05). Among transplant-eligible patients, those who underwent LT had a significantly longer postrecurrence survival. CONCLUSIONS: This study showed that the presence of a LT program was associated with decreased PHLF rates and an increased probability to receive SLT in case of recurrence.

Metabolic syndrome (MetS) is a common condition closely associated with non-alcoholic fatty liver disease/non-alcoholic steatohepatitis (NAFLD/NASH). Recent meta-analyses show that MetS can be prodromal to intrahepatic cholangiocarcinoma (iCCA) development, a liver tumor with features of biliary differentiation characterized by dense extracellular matrix (ECM) deposition. Since ECM remodeling is a key event in the vascular complications of MetS, we aimed at evaluating whether MetS patients with iCCA present qualitative and quantitative changes in the ECM able to incite biliary tumorigenesis. In 22 iCCAs with MetS undergoing surgical resection, we found a significantly increased deposition of osteopontin (OPN), tenascin C (TnC), and periostin (POSTN) compared to the matched peritumoral areas. Moreover, OPN deposition in MetS iCCAs was also significantly increased when compared to iCCA samples without MetS (non-MetS iCCAs, n = 44). OPN, TnC, and POSTN significantly stimulated cell motility and the cancer-stem-cell-like phenotype in HuCCT-1 (human iCCA cell line). In MetS iCCAs, fibrosis distribution and components differed quantitatively and qualitatively from non-MetS iCCAs. We therefore propose overexpression of OPN as a distinctive trait of MetS iCCA. Since OPN stimulates malignant properties of iCCA cells, it may provide an interesting predictive biomarker and a putative therapeutic target in MetS patients with iCCA.

BACKGROUND: Despite second-line transplant(SLT) for recurrent hepatocellular carcinoma(rHCC) leads to the longest survival after recurrence(SAR), its real applicability has never been reported. The aim was to compare the SAR of SLT versus repeated hepatectomy and thermoablation(CUR group). METHODS: Patients were enrolled from the Italian register HE.RC.O.LE.S. between 2008 and 2021. Two groups were created: CUR versus SLT. A propensity score matching (PSM) was run to balance the groups. RESULTS: 743 patients were enrolled, CUR = 611 and SLT = 132. Median age at recurrence was 71(IQR 6575) years old and 60(IQR 53-64, p < 0.001) for CUR and SLT respectively. After PSM, median SAR for CUR was 43 months(95%CI = 37 - 93) and not reached for SLT(p < 0.001). SLT patients gained a survival benefit of 9.4 months if compared with CUR. MilanCriteria(MC)-In patients were 82.7% of the CUR group. SLT(HR 0.386, 95%CI = 0.23 - 0.63, p < 0.001) and the MELD score(HR 1.169, 95%CI = 1.07 - 1.27, p < 0.001) were the only predictors of mortality. In case of MC-Out, the only predictor of mortality was the number of nodules at recurrence(HR 1.45, 95%CI= 1.09 - 1.93, p = 0.011). CONCLUSION: It emerged an important transplant under referral in favour of repeated hepatectomy or thermoablation. In patients with MC-Out relapse, the benefit of SLT over CUR was not observed.

BACKGROUND: Spontaneous intracranial hypotension (SIH) is a syndrome characterized by low cerebrospinal fluid (CSF) pressure and postural headaches, and affects 1 per 20,000 individuals every year. CASE REPORT: We report an otherwise healthy 38-year-old man admitted to the hospital with orthostatic headache that developed 48 h after a short-haul flight during which he sustained a neck injury due to turbulence. Neurological examination, blood analysis and computed tomography scan performed at the emergency service were normal. Brain and spine magnetic resonance imaging (MRI) showed diffuse pachymeningeal enhancement and contrast medium egress from the subarachnoid space into the epidural space at the level of C2. The patient was treated with bed rest, hydration and 1 mg/kg/day oral prednisone for 5 days, with a gradual withdrawal in the following 7 days. Complete symptomatic relief was observed after 16 days, with resolution of the pathological findings on brain and spinal MRI after 1 month, except for localized pachymeningeal enhancement. Clinical relief was maintained over time until last follow-up visit 9 months later. CONCLUSION: Successful conservative treatment barely exceeds one quarter of cases of SIH. The clinical benefits of steroids may result from several mechanisms of action, for example, improving brain oedema and inflammation, determining fluid retention, and facilitating reabsorption of the CSF from extradural space. Notwithstanding that epidural blood patch remains the most successful treatment for SIH, future studies should explore the effectiveness of steroids as first-line therapy in addition to the most commonly suggested measures of bed rest and hydration.

BACKGROUND: Benchmark analysis for open liver surgery for cirrhotic patients with hepatocellular carcinoma (HCC) is still undefined. METHODS: Patients were identified from the Italian national registry HE.RC.O.LE.S. The Achievable Benchmark of Care (ABC) method was employed to identify the benchmarks. The outcomes assessed were the rate of complications, major comorbidities, post-operative ascites (POA), post-hepatectomy liver failure (PHLF), 90-day mortality. Benchmarking was stratified for surgical complexity (CP1, CP2 and CP3). RESULTS: A total of 978 of 2698 patients fulfilled the inclusion criteria. 431 (44.1%) patients were treated with CP1 procedures, 239 (24.4%) with CP2 and 308 (31.5%) with CP3 procedures. Patients submitted to CP1 had a worse underlying liver function, while the tumor burden was more severe in CP3 cases. The ABC for complications (13.1%, 19.2% and 28.1% for CP1, CP2 and CP3 respectively), major complications (7.6%, 11.1%, 12.5%) and 90-day mortality (0%, 3.3%, 3.6%) increased with the surgical difficulty, but not POA (4.4%, 3.3% and 2.6% respectively) and PHLF (0% for all groups). CONCLUSION: We propose benchmarks for open liver resections in HCC cirrhotic patients, stratified for surgical complexity. The difference between the benchmark values and the results obtained during everyday practice reflects the room for potential growth, with the aim to encourage constant improvement among liver surgeons.

BACKGROUND: We aimed to evaluate, in a large Western cohort, perioperative and long-term oncological outcomes of salvage hepatectomy (SH) for recurrent hepatocellular carcinoma (rHCC) after primary hepatectomy (PH) or locoregional treatments. METHODS: Data were collected from the Hepatocarcinoma Recurrence on the Liver Study Group (He.RC.O.Le.S.) Italian Registry. After 1:1 propensity score-matched analysis (PSM), two groups were compared: the PH group (patients submitted to resection for a first HCC) and the SH group (patients resected for intrahepatic rHCC after previous HCC-related treatments). RESULTS: 2689 patients were enrolled. PH included 2339 patients, SH 350. After PSM, 263 patients were selected in each group with major resected nodule median size, intraoperative blood loss and minimally invasive approach significantly lower in the SH group. Long-term outcomes were compared, with no difference in OS and DFS. Univariate and multivariate analyses revealed only microvascular invasion as an independent prognostic factor for OS. CONCLUSION: SH proved to be equivalent to PH in terms of safety, feasibility and long-term outcomes, consistent with data gathered from East Asia. In the awaiting of reliable treatment-allocating algorithms for rHCC, SH appears to be a suitable alternative in patients fit for surgery, regardless of the previous therapeutic modality implemented.

BACKGROUND: Management of recurrence after surgery for hepatocellular carcinoma (rHCC) is still a debate. The aim was to compare the Survival after Recurrence (SAR) of curative (surgery or thermoablation) versus palliative (TACE or Sorafenib) treatments for patients with rHCC. METHODS: This is a multicentric Italian study, which collected data between 2007 and 2018 from 16 centers. Selected patients were then divided according to treatment allocation in Curative (CUR) or Palliative (PAL) Group. Inverse Probability Weighting (IPW) was used to weight the groups. RESULTS: 1,560 patients were evaluated, of which 421 experienced recurrence and were then eligible: 156 in CUR group and 256 in PAL group. Tumor burden and liver function were weighted by IPW, and two pseudo-population were obtained (CUR = 397.5 and PAL = 415.38). SAR rates at 1, 3 and 5 years were respectively 98.3%, 76.7%, 63.8% for CUR and 91.7%, 64.2% and 48.9% for PAL (p = 0.007). Median DFS was 43 months (95%CI = 32-74) for CUR group, while it was 23 months (95%CI = 18-27) for PAL (p = 0.017). Being treated by palliative approach (HR = 1.75; 95%CI = 1.14-2.67; p = 0.01) and having a median size of the recurrent nodule>5 cm (HR = 1.875; 95%CI = 1.22-2.86; p = 0.004) were the only predictors of mortality after recurrence, while time to recurrence was the only protective factor (HR = 0.616; 95%CI = 0.54-0.69; p<0.001). CONCLUSION: Curative approaches may guarantee long-term survival in case of recurrence.

Benign biliary tumor are common lesions that are often an incidental finding in subjects who undergo medical imaging tests for other conditions. Most are true neoplasms while few result from reactive or malformative proliferation. Benign tumors have no clinical consequences, although the premalignant nature or potential for malignant transformation is of concern in some cases. The main practical problem for pathologists is the need to differentiate them from malignant biliary tumours, which is not always straightforward.Premalignant lesions of the bile duct have been described, although their incidence has been poorly characterized. These lesions include biliary mucinous cystic neoplasms, intraductal papillary neoplasms of the bile duct, and biliary intraepithelial neoplasia. In this article, histopathology of benign biliary tumors and biliary tumor precursors is discussed, with a focus on the main diagnostic criteria.

Liver cancer represents the third leading cause of cancer-related death worldwide. Cholangiocarcinoma (CCA) is the second most common type of liver cancer after hepatocellular carcinoma, accounting for 10-15% of all primary liver malignancies. Both the incidence and mortality of CCA have been steadily increasing during the last decade. Moreover, most CCAs are diagnosed at an advanced stage, when therapeutic options are very limited.CCA may arise from any tract of the biliary system and it is classified into intrahepatic, perihilar, and distal CCA, according to the anatomical site of origin. This topographical classification also reflects distinct genetic and histological features, risk factors, and clinical outcomes. This review focuses on histopathology of CCA, its differential diagnoses, and its diagnostic pitfalls.

OBJECTIVE: The aim of this study was to evaluate correlation between centers' volume and incidence of failure to rescue (FTR) following liver resection for hepatocellular carcinoma (HCC). SUMMARY BACKGROUND DATA: FTR, defined as the probability of postoperative death among patients with major complication, has been proposed to assess quality of care during hospitalization. Perioperative management is challenging in cirrhotic patients and the ability to recognize and treat a complication may be fundamental to rescue patients from the risk of death. METHODS: Patients undergoing liver resection for HCC between 2008 and 2018 in 18 Centers enrolled in the He.Rc.O.Le.S. Italian register. Early results included major complications (Clavien ≥3), 90-day mortality, and FTR and were analyzed according to center's volume. RESULTS: Among 1935 included patients, major complication rate was 9.4% (8.6%, 12.3%, and 7.0% for low-, intermediate- and high-volume centers, respectively, P = 0.001). Ninety-day mortality rate was 2.6% (3.7%, 4.2% and 0.9% for low-, intermediate- and high-volume centers, respectively, P < 0.001). FTR was significantly higher at low- and intermediate-volume centers (28.6% and 26.5%, respectively) than at high-volume centers (6.1%, P = 0.002). Independent predictors for major complications were American Society of Anesthesiologists (ASA) >2, portal hypertension, intraoperative blood transfusions, and center's volume. Independent predictors for 90-day mortality were ASA >2, Child-Pugh score B, BCLC stage B-C, and center's volume. Center's volume and BCLC stage were strongly associated with FTR. CONCLUSIONS: Risk of major complications and mortality was related with comorbidities, cirrhosis severity, and complexity of surgery. These factors were not correlated with FTR. Center's volume was the only independent predictor related with severe complications, mortality, and FTR.

Italy has been the first-hit European country to face the outbreak of coronavirus disease 2019 (COVID-19). Aim of this survey was to assess in depth the impact of the outbreak on healthcare workers (HCW). A 40-item online survey was disseminated via social media inviting Italian HCW, with questions exploring demographics, health status and work environment of respondents. A total of 527 were invited to take part in March 2020, of whom 74% (n = 388) responded to the survey. Of these, 235 (61%) were women. HCW were mostly physicians (74%), from high-prevalence regions (52%). 25% experienced typical symptoms during the last 14 days prior to survey completion, with only 45% of them being tested for COVID-19. Among the tested population, 18 (18%) resulted positive for COVID-19, with 33% being asymptomatic. Only 22% of HCW considered personal protective equipment adequate for quality and quantity. Females and respondents working in high-risk sectors were more likely to rate psychological support as useful (OR, 1.78 [CI 95% 1.14-2.78] P = 0.012, and 2.02 [1.12-3.65] P = 0.020, respectively) and workload as increased (mean increase, 0.38 [0.06-0.69] P = 0.018; and 0.54 [0.16-0.92] P = 0.005, respectively). The insights from this survey may help authorities in countries where COVID-19 epidemic has not yet broken out. Management strategies should be promptly undertaken in order to enhance safety and optimise resource allocation.

BACKGROUND: Videolaparoscopic (VL) microwave ablation (MWA) is not included in most of the international guidelines as a therapeutic option for hepatocellular carcinoma (HCC). Aim of this study was to assess the safety of VL MWA in patients with HCC for whom resection or percutaneous ablation is unsuitable. METHODS: A retrospective analysis was performed on a prospective database of patients with HCC treated with VL MWA at our institution from 2009 to 2016. Patient demographics, operational characteristics, and complications were recorded. Statistical analysis was performed to identify safety profile, overall survival and recurrence rate. RESULTS: A total of 815 VL MWA were performed in 674 patients with a mean age of 64 years. Patients had a mean Model for End-stage Liver Disease score of 10 (±3); 32.8% were Child B, 44.1% Barcelona Clinic Liver Cancer B-C. Perioperative mortality was 0.4%. Overall morbidity was 30.8%, with Dindo-Clavien complications ≥3 in 2%. The median length of stay was 2 days. In 43.1% VL MWA was the first-line therapy. Overall 1-, 3-, and 5-year survival rates were 81.9%, 54.9%, and 35.9%. CONCLUSIONS: The present is the largest series of VL ablation and the bigger number of patients with HCC treated with MW reported nowadays. It confirms the safety of a minimally invasive procedure for patients with HCC when resection or percutaneous ablation is not feasible.

UNLABELLED: Spontaneous bacterial peritonitis (SBP) is a common, life-threatening complication of liver cirrhosis. Third-generation cephalosporins have been considered the first-line treatment of SBP. In 2014, a panel of experts suggested a broader spectrum antibiotic regimen for nosocomial SBP, according to the high rate of bacteria resistant to third-generation cephalosporins found in these patients. However, a broader-spectrum antibiotic regimen has never been compared to third-generation cephalosporins in the treatment of nosocomial SBP. The aim of our study was to compare meropenem plus daptomycin versus ceftazidime in the treatment of nosocomial SBP. Patients with cirrhosis and nosocomial SBP were randomized to receive meropenem (1 g/8 hours) plus daptomycin (6 mg/kg/day) or ceftazidime (2 g/8 hours). A paracentesis was performed after 48 hours of treatment. A reduction in ascitic fluid neutrophil count <25% of pretreatment value was considered a treatment failure. The primary outcome was the efficacy of treatment defined by the resolution of SBP after 7 days of treatment. Thirty-two patients were randomized and 31 were analyzed. The combination of meropenem plus daptomycin was significantly more effective than ceftazidime in the treatment of nosocomial SBP (86.7 vs. 25%; P < 0.001). Ninety-day transplant-free survival (TFS) was not significantly different between the two groups. In the multivariate analysis, ineffective response to first-line treatment (hazard ratio [HR]: 20.6; P = 0.01), development of acute kidney injury during hospitalization (HR: 23.2; P = 0.01), and baseline mean arterial pressure (HR: 0.92; P = 0.01) were found to be independent predictors of 90-day TFS. CONCLUSION: The combination of meropenem plus daptomycin is more effective than ceftazidime as empirical antibiotic treatment of nosocomial SBP. Efficacy of the empirical antibiotic treatment is a strong predictor of 90-day survival in patients with nosocomial SBP.

PURPOSE: To assess the safety, tolerability, and efficacy of small drug-eluting embolic (DEE) agents (70-150 µm) for chemoembolization of hepatocellular carcinoma (HCC). MATERIALS AND METHODS: This single-center, single-arm, retrospective study involved 421 patients (mean age, 66.1 y ± 9.8 [standard deviation]) with Barcelona Clinic Liver Cancer (BCLC) stage A (n = 88), B (n = 140), or C (n = 193) HCC and Child-Pugh class A (n = 233) or B (n = 188) cirrhosis. Patients had a mean of 7.2 lesions ± 4.8 (range, 1-21; mean diameter of target lesion, 21.4 cm ± 8.1; unilobar, n = 132; bilobar, n = 289; portal vein involvement, n = 193). One (n = 320) or 2 (n = 101) vials of small DEEs loaded with doxorubicin 50 mg per vial were delivered selectively (ie, segmentally) or superselectively (ie, directly into the tumor-feeding vessel) until complete delivery or stasis/near-stasis. Treatment was repeated in patients with partial response or stable disease at 1- or 3-month follow-up (mean, 2.0 cycles ± 0.9). Adverse events within 30 days of chemoembolization, response per modified Response Evaluation Criteria In Solid Tumors (mRECIST), and survival were assessed. RESULTS: Within 30 days after treatment, no deaths or bleeding events occurred, but all patients had at least 1 episode of postembolization syndrome (pain, fever, and/or nausea/vomiting; 27.1% grade 3/4 per National Cancer Institute Common Terminology Criteria for Adverse Events, version 3.0) and increased bilirubin and liver aminotransferase levels (0.2% and 5.9% grade 3/4, respectively). Overall response rates were 94.5% at 3 months and 99.5% at 6 months. Median overall survival was 42.0 months (95% confidence interval, 38.0-43.0 mo). CONCLUSIONS: Chemoembolization with small DEE agents is well tolerated and an effective treatment for a broad range of patients with liver-confined HCC.

The hepatitis C virus (HCV) infects more than 180 million people globally, with increasing incidence, especially in developing countries. HCV infection frequently progresses to liver cirrhosis leading to liver transplantation or death, and HCV recurrence still constitutes a major challenge for the transplant team. Antiviral therapy is the only available instrument to slow down this process, although its actual impact on liver histology, in responders and nonresponders, is still controversial. We are now facing a "new era" of direct antiviral agents that is already changing the approach to HCV burden both in the pre- and in the post-liver transplantation settings. Available data on sofosbuvir/ledipasvir and sofosbuvir/simeprevir in patients with decompensated cirrhosis sustain a SVR12 of 89% , but one-third of patients do not clinically improved. The sofosbuvir/ribavirin treatment in stable cirrhotic patients with HCC before liver transplantation is associated with 2% recurrence rate if liver transplantation is performed at least one month after undetectable HCV-RNA is achieved. The treatment of recurrence with the new antiviral drugs is associated with a SVR that ranges between 60 and 90%. In this review, we have focused on the evolution of antiviral therapy for HCV recurrence from the "old" interferon-based therapy to the "new" interferon-free regimens, highlighting useful information to aid the transplant hepatologist in the clinical practice.

BACKGROUND & AIMS: A slowed electroencephalogram (EEG) is indicative of the presence of hepatic encephalopathy (HE). Since HE is not reflected in the MELD score and is an important prognostic parameter, we assess the prognostic benefit of the addition of an EEG-based HE index to the MELD. METHODS: Three hundred and ninety-two patients with cirrhosis underwent EEG and automated determination of its mean dominant frequency (MDF). MELD was calculated at the time of EEG recording. Patients were monitored for up to 18 months in relation to the occurrence of death/transplantation. The prognostic value of the stand-alone/combined MELD and MDF was calculated using standard survival analysis techniques. Patients transplanted for hepatic decompensation were considered dead on the day of transplantation, those transplanted for hepatocellular carcinoma were censored. The findings were validated using a split-sample technique (reference group: n = 256; test group: n = 136). During the follow-up period, 107 patients died/were transplanted for hepatic decompensation. RESULTS: Both MELD and MDF predicted mortality on Kaplan-Meier analysis, and both were independent predictors of mortality on a Cox model. Based on Cox regression parameters, a novel prognostic index was devised, as follows: MELD-EEG = 0.087*MELD-0.306*MDF. On ROC curve analysis, MELD-EEG had higher prognostic accuracy in predicting 12- and 18-month mortality compared to MELD (P = 0.016 and P = 0.018, respectively). In addition, it had better sensitivity and reduced the misclassification rate for given levels of specificity. On validation, no significant differences were observed between the reference/test groups. CONCLUSIONS: The addition of an automatically obtained EEG-based index improves the prognostic accuracy of the MELD score.

The detection of alcohol consumption in liver transplant candidates (LTCs) and liver transplant recipients (LTRs) is required to enable a proper assessment of transplant eligibility and early management of alcohol relapse, respectively. In this clinical setting, urinary ethyl glucuronide (uEtG), the Alcohol Use Disorders Identification Test for Alcohol Consumption (AUDIT-c), serum ethanol, urinary ethanol, carbohydrate-deficient transferrin (CDT), and other indirect markers of alcohol consumption were evaluated and compared prospectively in 121 LTCs and LTRs. Alcohol consumption was diagnosed when AUDIT-c results were positive or it was confirmed by a patient's history in response to abnormal results. Alcohol consumption was found in 30.6% of the patients. uEtG was found to be the strongest marker of alcohol consumption (odds ratio = 414.5, P < 0.001) and provided a more accurate prediction rate of alcohol consumption [area under receiving operating characteristic (ROC) curve = 0.94] than CDT (area under ROC curve = 0.63, P < 0.001) and AUDIT-c (area under ROC curve = 0.73, P < 0.001). The combination of uEtG and AUDIT-c showed higher accuracy in detecting alcohol consumption in comparison with the combination of CDT and AUDIT-c (area under ROC curve = 0.98 versus 0.80, P < 0.001). Furthermore, uEtG was the most useful marker for detecting alcohol consumption in patients with negative AUDIT-c results. In conclusion, the combination of AUDIT-c and uEtG improves the detection of alcohol consumption in LTCs and LTRs. Therefore, they should be used routinely for these patients.
