Percutaneous ablation is recommended in Barcelona Clinic Liver Cancer (BCLC) stage 0/A patients with HCC ≤3 cm as a curative treatment modality alongside surgical resection and liver transplantation. However, trans-arterial chemo-embolisation (TACE) is commonly used in the real-world as an initial treatment in patients with single small HCC in contrast to widely accepted clinical practice guidelines which typically describe TACE as a treatment for intermediate-stage HCC. We performed this real-world propensity-matched multi-centre cohort study in patients with single HCC ≤ 3 cm to assess for differences in survival outcomes between those undergoing initial TACE and those receiving upfront ablation. Patients with a new diagnosis of BCLC 0/A HCC with a single tumour ≤3 cm first diagnosed between 1 January 2016 and 31 December 2020 who received initial TACE or ablation were included in the study. A total of 348 patients were included in the study, with 147 patients receiving initial TACE and 201 patients undergoing upfront ablation. After propensity score matching using key covariates, 230 patients were available for analysis with 115 in each group. There were no significant differences in overall survival (log-rank test p = 0.652) or liver-related survival (log-rank test p = 0.495) over a median follow-up of 43 months. While rates of CR were superior after ablation compared to TACE as a first treatment (74% vs. 56%, p < 0.004), there was no significant difference in CR rates when allowing for further subsequent treatments (86% vs. 80% p = 0.219). In those who achieved CR, recurrence-free survival and local recurrence-free survival were similar (log rank test p = 0.355 and p = 0.390, respectively). Our study provides valuable real-world evidence that TACE when offered with appropriate follow-up treatment is a reasonable initial management strategy in very early/early-stage HCC, with similar survival outcomes as compared to those managed with upfront ablation. Further work is needed to better define the role for TACE in BCLC 0/A HCC.

The management of early-stage hepatocellular carcinoma (HCC) is complex, with multiple treatment strategies available. There is a paucity of literature regarding variations in the patterns of care and outcomes between transplant and non-transplant centres. We conducted this real-world multi-centre cohort study in two liver cancer referral centres with an integrated liver transplant program and an additional eight non-transplant HCC referral centres across Australia to identify variation in patterns of care and key survival outcomes. Patients with stage Barcelona Clinic Liver Cancer (BCLC) 0/A HCC, first diagnosed between 1 January 2016 and 31 December 2020, who were managed at a participating site, were included in the study. Patients were excluded if they had a history of prior HCC or if they received upfront liver transplantation. A total of 887 patients were included in the study, with 433 patients managed at a liver cancer centre with a transplant program (LTC) and 454 patients managed at a non-transplant centre (NTC). Management at an LTC did not significantly predict allocation to resection (adjusted OR 0.75, 95% CI 0.50 to 1.11, p = 0.148). However, in those not receiving resection, LTC and NTC patients were systematically managed differently, with LTC patients five times less likely to receive upfront ablation than NTC patients (adjusted OR 0.19, 95% CI 0.13 to 0.28, p < 0.001), even after adjusting for tumour burden, as well as for age, gender, liver disease aetiology, liver disease severity, and medical comorbidities. LTCs exhibited significantly higher proportions of patients undergoing TACE for every tumour burden category, including those with a single tumour measuring 2 cm or less ( p < 0.001). Using multivariable Cox proportional hazards analysis, management at a transplant centre was associated with reduced all-cause mortality (adjusted HR 0.71, 95% CI 0.51 to 0.98, p = 0.036), and competing-risk regression analysis, considering liver transplant as a competing event, demonstrated a similar reduction in risk (adjusted HR 0.70, 95% CI 0.50 to 0.99, p = 0.041), suggesting that the reduced risk of death is not fully explained by higher rates of transplantation. Our study highlights systematic differences in HCC care between large volume liver transplant centres and other sites, which has not previously been well-described. Further work is needed to better define the reasons for differences in treatment allocation and to aim to minimise unwarranted treatment variation to maximise patient outcomes across Australia.

Background: Acute-on-chronic liver failure (ACLF) represents a rising global healthcare burden, characterised by increasing prevalence among patients with decompensated cirrhosis who have a 28-day transplantation-free mortality of 33.9%. Due to disease complexity and a high prevalence of socio-economic disadvantage, there are deficits in quality of care and adherence to guideline-based treatment in this cohort. Compared to other chronic conditions such as heart failure, those with liver disease have reduced access to integrated ambulatory care services. The LivR Well programme is a multidisciplinary intervention aimed at improving 28-day mortality and reducing 30-day readmission through a home-based, liver optimisation programme implemented in the first 28 days after an admission with either ACLF or hepatic decompensation. Outcomes from our feasibility study suggest that the intervention is safe and acceptable to patients and carers., Methods: We will recruit adult patients with chronic liver disease from the emergency departments, in-patient admissions, and an ambulatory liver clinic of a multi-site quaternary health service in Melbourne, Australia. A total of 120 patients meeting EF-Clif criteria will be recruited to the ACLF arm, and 320 patients to the hepatic decompensation arm. Participants in each cohort will be randomised to the intervention arm, a 28-day multidisciplinary programme or to standard ambulatory care in a 1:1 ratio. The intervention arm includes access to nursing, pharmacy, physiotherapy, dietetics, social work, and neuropsychiatry clinicians. For the ACLF cohort, the primary outcome is 28-day mortality. For the hepatic decompensation cohort, the primary outcome is 30-day re-admission. Secondary outcomes assess changes in liver disease severity and quality of life. An interim analysis will be performed at 50% recruitment to consider early cessation of the trial if the intervention is superior to the control, as suggested in our feasibility study. A cost-effectiveness analysis will be performed. Patients will be followed up for 12 weeks from randomisation. Three exploratory subgroup analyses will be conducted by (a) source of referral, (b) unplanned hospitalisation, and (c) concurrent COVID-19. The trial has been registered with the Australian New Zealand Clinical Trials Registry., Discussion: This study implements a multidisciplinary intervention for ACLF patients with proven benefits in other chronic diseases with the addition of novel digital health tools to enable remote patient monitoring during the COVID-19 pandemic. Our feasibility study demonstrates safety and acceptability and suggests clinical improvement in a small sample size. An RCT is required to generate robust outcomes in this frail, high healthcare resource utilisation cohort with high readmission and mortality risk. Interventions such as LivR Well are urgently required but also need to be evaluated to ensure feasibility, replicability, and scalability across different healthcare systems. The implications of this trial include the generalisability of the programme for implementation across regional and urban centres., Trial Registration: Australian New Zealand Clinical Trials Registry (ANZCTR) ACTRN12621001703897 .

Background and Aim: Patients with refractory ascites have frequent hospital admissions, which pose exposure risks in the context of the COVID-19 pandemic. The aim of this study was to investigate the safety and efficacy of a novel 12-week, multidisciplinary ambulatory care program allowing frequent low-volume ascitic drainage through a tunneled, intraperitoneal catheter (IPC)., Methods: Adult patients with cirrhosis complicated by refractory ascites were recruited through a liver clinic in a tertiary health service in Melbourne, Australia from April to December 2020. All patients were enrolled in a 12-week multidisciplinary program including medical, nursing, dietetics, and pharmacy support. A Rocket Medical IPC was inserted on day 1 with 1-2 L of ascitic fluid drained over 1-3 sessions per week either at the patients' homes or at the hospital day ward. Patients' demographics, death, complications, and self-reported outcomes were recorded., Results: Twelve patients were enrolled with a median of 65-day (interquartile range [IQR]: 16.5-93) IPC duration between April and December 2020 across two periods of COVID-related lockdown in Melbourne, Australia. There were no IPC-related deaths. Early removal was necessitated in three patients due to leakage, nonadherence, and bacteremia. On day 30, the median self-reported health score increased from 50 (IQR: 50-70) to 78 (IQR: 50-85), attributable to a reduction in symptom burden., Conclusion: A multidisciplinary IPC program including the use of short-term IPC was safe and associated with a self-reported improvement in perceptions of health. In the context of the COVID-19 pandemic, the program aimed to reduce patient and clinician exposure, which is maintaining engagement and management of decompensated cirrhosis., (© 2021 The Authors.

Introduction: Percutaneous transluminal angioplasty (PTA) and surgical bypass (BYP) are treatment options for symptomatic peripheral arterial disease (PAD). PTA and BYP have different clinical outcomes and cost implications. This paper aims to compare hospital-related costs of PTA and BYP for PAD of the lower limbs in an Australian health service., Methods: A retrospective cost analysis using clinical and financial data from an urban, tertiary hospital was performed. Patient cohorts were matched to existing published studies and 3-year findings were calculated. Outcomes measured were mean initial admission cost; mean bed stay; mean complication rate; mean cost of re-intervention at 12 months and extrapolated mean cost at 3 years., Results: The mean total admission costs for PTA compared to BYP were $8758 vs. $27,849 (P < 0.001). Patients undergoing BYP were admitted for 10.25 vs. 3.77 nights (P < 0.001). The complication rate was greater in the BYP group for infection only. Re-intervention was required by 13% of the PTA group and 16% of the BYP group, at a mean cost of $11,798 and $14,728, respectively (P = 0.453). The extrapolated total mean cost at 3 years was higher in the BYP group for patients with both intermittent claudication ($26,764 vs. $11,402) and critical limb ischaemia ($27,719 vs. $12,655)., Conclusions: In this cohort, PTA is a favourable alternative to BYP for PAD of the lower limbs as it is less costly, does not result in a greater re-intervention rate at 1 year and has been previously demonstrated to have comparable clinical outcomes. Given the limitations of this retrospective analysis, a prospective cost-effectiveness analysis is recommended., (© 2018 The Royal Australian and New Zealand College of Radiologists.)

Background and Aims: Despite worldwide reductions in active smoking, non-smokers continue to be exposed to environmental tobacco smoke, especially at home or workplace. There is a well-recognised association between active smoking and peripheral arterial disease, however, a relationship to environmental tobacco smoke exposure is less substantiated. The aims of this paper are to review the literature regarding the association between environmental tobacco smoke and peripheral arterial disease and identify the public health implications of the findings., Methods: Selected electronic databases (Medline, EMBASE, CINAHL, PsychINFO and Scopus) were searched for studies published up to August 2017. Key words and inclusion/exclusion criteria applied. A manual search of reference lists of studies selected for review was also performed., Results: Of the initial 150 studies identified, 12 met inclusion criteria for review. Three studies showed a positive association between environmental tobacco smoke exposure and definitive diagnosis of peripheral arterial disease, 6 studies demonstrated a positive association with features of vascular injury, and 3 studies found no significant positive or negative association., Conclusions: An association between exposure to environmental tobacco smoke and development of peripheral arterial disease or clinically significant arterial injury in non-smokers is supported by moderate quality evidence in the literature. Larger, longitudinal observational studies addressing current limitations, including sources of bias, inconsistency and imprecision, are needed to provide more robust and consistent evidence. Regardless, evidence of potential detrimental impacts supports ongoing restrictions on freedom to smoke in public areas, including the workplace, and has implications for those exposed in the home environment., (Copyright © 2017 Elsevier B.V.
