Abstract
Hepatocellular carcinoma (HCC) is the most common primary liver tumor in adults, and the fourth leading cause of cancer-related deaths worldwide. While surgical and ablative therapies remain the standard of care in early localized disease, late presentation with advanced stages of disease, impaired hepatic function, or local recurrence following surgical resection preclude operative management as the sole treatment modality in a subgroup of patients. As such, systemic therapies, namely immunotherapy, have become an integral part of the HCC treatment algorithm over the past decade. While agents, such as atezolizumab/bevacizumab, have well-established roles as first-line systemic therapy in intermediate- and advanced-stage HCC, the role of immunotherapy in disease amenable to surgical management continues to evolve. In this review, we will discuss the current evidence and aggregate impact of immunotherapy in the context of HCC amenable to surgical management, including its application in the neoadjuvant and adjuvant settings.

Abstract
The increasing prevalence of diabetes mellitus, obesity, and metabolic syndrome in the population can lead to metabolic dysfunction-associated steatohepatitis (MASH) and metabolic dysfunction-associated steatotic liver disease (MASLD). In Western industrialized countries, this has become a major problem with significant socioeconomic impacts. MASH is now a leading cause of liver transplantation (LT), especially in developed countries. However, the post-transplant outcomes of such patients are a major concern, and published data are limited and extremely variable. In this article, we discuss graft and patient survival after LT, complications, the recurrence of MASH, and MASH appearing de novo after transplantation. Recent studies suggest that patients with MASH have slightly worse short-term survival, potentially due to increased cardiovascular mortality. However, most studies found that longer-term outcomes for patients undergoing LT for MASH are similar or even better than those for other indications. Hepatocellular carcinoma due to MASH cirrhosis also has similar or even better outcomes after LT than other etiologies. In conclusion, we suggest questions and topics that require further research to enhance healthcare for this growing patient population.

Int J Surg 2022; 104:106752. [PMID: 35803515 DOI: 10.1016/j.ijsu.2022.106752] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2022] [Revised: 06/18/2022] [Accepted: 06/20/2022] [Indexed: 12/29/2022]
Abstract
OBJECTIVE Nonalcoholic steatohepatitis (NASH) is a dramatically growing indication for liver transplantation (LT) worldwide and the posttransplant outcomes of NASH patients are currently under intensive investigation. This quantitative meta-analysis aimed to update the clinical evidence on outcomes of transplanted patients with NASH. METHODS We performed a systematic review and meta-analysis of studies (published up to September 15, 2021) that focused on LT outcomes for NASH versus non-NASH patients. Random-effect meta-analysis was conducted to calculate pooled odds ratios (ORs) and 95% confidence intervals (CIs). Subgroup analyses based on crucial baseline clinical characteristics and leave-one-out sensitivity analyses were conducted to assess the robustness of the pooled results. Meta-regression was used to evaluate study-level demographic, clinical, and biochemical characteristics to identify potential confounders affecting patient survival. RESULTS Twenty-two non-randomized comparative studies with 1,538 NASH and 6,014 non-NASH patients were included. 1- (OR, 0.94; 95% CI, 0.77-1.14), 3- (OR, 0.82; 95% CI, 1.00-1.22), and 5- (OR, 1.05; 95% CI, 0.84-1.31) year patient survival was equivalent between NASH and non-NASH recipients. NASH patients were associated with similar cardiovascular mortality (OR, 1.36; 95% CI, 0.89-2.09) and retransplantation rates (OR, 0.69; 95% CI, 1.03-1.53), lower graft failure-related mortality (OR, 0.11; 95% CI, 0.29-0.74), but higher sepsis-related mortality (OR, 1.53; 95% CI, 1.13-2.06). Meta-regression revealed that a higher proportion of patients with hepatocellular carcinoma (HCC) were associated with significantly superior overall patient survival at 1 (P = 0.044), 3 (P = 0.035) and 5 (P = 0.049) years after LT in NASH compared with non-NASH. CONCLUSIONS This study shows no difference in posttransplant survival between NASH and non-NASH patients. Carefully selected patients with NASH-related HCC may benefit from LT. NASH recipients should be managed with caution posttransplant, especially regarding the potentially high risk of sepsis-related death.

Nash Up, Virus Down: How the Waiting List Is Changing for Liver Transplantation: A Single Center Experience from Italy. Medicina (B Aires) 2022; 58:medicina58020290. [PMID: 35208613 PMCID: PMC8874675 DOI: 10.3390/medicina58020290] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2021] [Revised: 02/10/2022] [Accepted: 02/11/2022] [Indexed: 11/16/2022] Open
Abstract
Background and Objectives: Non-alcoholic steatohepatitis (NASH) has become the leading indication for liver transplantation in many countries, with a growing rate in the Western world. NASH patients are older and share a higher risk of comorbidities and cancer than patients with viral and/or alcoholic etiologies. The aims of this study were to evaluate waiting list (WL) registration and liver transplantation rates in patients with NASH-related cirrhosis at Padua University Hospital in the last fifteen years (1.2006–6.2020) and to compare clinical characteristics and indications for liver transplantation between patients with and without NASH, as well as the WL survival and post-transplant outcome. Materials and Methods: All adult patients with cirrhosis listed for liver transplantation at Padua University Hospital between 1.2006 and 6.2020 were retrospectively collected using a prospectively updated database; patients with NASH-related cirrhosis were divided by indication for liver transplantation (Dec-NASH vs. hepatocellular carcinoma (HCC)-NASH) and compared with patients with other etiologies of liver disease. The outcomes in terms of waiting list survival and post-transplant outcome were assessed. Results: One thousand four hundred and ninety-one adult cirrhotic patients were waitlisted during the study period. NASH patients accounted for 12% of all WL registrations, showing an increasing trend over time (from 2.5% in 2006 to 23% in 2020). In the last five years, NASH was the third, but most rapidly growing, indication for liver transplantation at our center. This trend was confirmed both for patients with decompensated cirrhosis (from 1.8% to 18%) and HCC as leading indication for transplantation (from 4% to 30%). NASH patients were older than non-NASH ones (mean ± SD age 59 ± 9 vs. 56 ± 9 years; p < 0.01), whereas no difference was found in gender or Child-Pugh of the model for end-stage liver disease score at WL registration. A majority (60.9%) of NASH patients underwent liver transplantation, showing 1-, 5- and 10-y post-transplant survivals of 86%, 73% and 60%, respectively. Conclusion: NASH cirrhosis has become a rapidly growing indication for liver transplantation at our center, both for HCC and decompensated disease, with good post-transplant survival.
