    Abstract Immune checkpoint inhibitors (ICIs) have emerged as the primary treatment for advanced hepatocellular carcinoma (HCC) and have shown promise in the neoadjuvant setting prior to resection. Liver transplantation (LT) is the preferred treatment for unresectable early HCC or locally advanced disease post locoregional therapy, but the need for immunosuppression after LT conflicts with ICIs' immune augmenting effects. Neoadjuvant ICI may benefit select LT candidates, but challenges arise in understanding response indicators and managing post-LT risks. Reports of severe rejection after LT have raised concerns, though liver-specific factors may mitigate rejection risks, prompting exploration of pre-LT ICI usage. While focus has been on PD-1/PD-L1 inhibitors, the optimal pre-LT ICI regimen remains uncertain, and trials must emphasize careful patient selection and management. Living donor LT is advantageous because ICIs can be withheld for a predefined washout period. In the post-LT setting, use of ICIs is generally avoided, though a few reports suggest that PD-L1 expression in the transplanted liver may be a safety biomarker and that, despite the risk, ICI therapy may be better than supportive care for patients with otherwise-untreatable HCC recurrence. This expert opinion highlights the complexities in the management of HCC vis-à-vis LT. Prospective studies and biomarkers are needed to define safe and effective pre- and post-LT immunotherapy protocols.

    Abstract A quarter century has passed since the milestone study by Mazzaferro and colleagues on liver transplantation (LT) for hepatocellular carcinoma (HCC). The increasing demand for LT for HCC has led to the continued efforts to expand LT indications. Downstaging to within Milan criteria has been incorporated into the organ allocation policy for HCC in the United States in 2017 and provides acceptable long-term survival. The present review focuses on the rationale of neoadjuvant immune checkpoint inhibitor (ICI) in HCC, the experience of ICI in the pre- and posttransplant setting.

    Abstract Purpose of review: The increasing success of liver transplantation in hepatocellular carcinoma (HCC) drives an ever-evolving search for innovative strategies to broaden eligible patients' pools. Recent advances in immuno-oncology have turned the spotlight on immune checkpoint inhibitors (ICIs). This review offers an updated overview of ICIs in liver transplantation for HCC, exploring neoadjuvant and adjuvant approaches and addressing unanswered questions on safety, patients' selection, and response predictors.
    Recent findings: ICIs have transitioned from being a last-chance therapeutic hope to becoming an integral cornerstone in the treatment of advanced HCC, holding great promise as a compelling option not only to downstage patients for transplantation but also as an alternative strategy in addressing posttransplantation disease recurrence. Despite ongoing refinements in immunotherapeutic agents, the complex molecular pathways involved emphasize the need for a comprehensive approach to integrate immunotherapy in liver transplantation.
    Summary: Initial concerns about graft rejection, with ICIs as a bridging therapy to liver transplantation, were successfully addressed using adequate immunosuppressants strategies and minimized with a sufficient washout period. Post-liver transplantation disease recurrence remains challenging, requiring a balance between effective therapy and preserving graft function. Emphasis should be placed on clinical trials validating the risk-benefit ratio of ICIs for liver transplantation, guiding appropriate patients' selection, and establishing clear management pathways.

    Abstract Background and objective: Hepatocellular carcinoma (HCC) is a leading cause of morbidity and mortality in the United States. For certain patients, liver transplantation (LT) may be curative. The determination of which patients would benefit most from transplant and have the lowest risk of post-transplant recurrence has evolved as technology and treatments have expanded. We aim to review epidemiological changes in the HCC landscape, selection criteria for transplant, organ allocation, bridge therapies and post-transplant recurrence, and identify points for palliative care involvement.
    Methods: Literature review was performed using PubMed MeSH searches in addition to reference list review. Additional information was retrieved from government regulatory and procurement organizations.
    Key content and findings: Metabolic and alcohol-associated liver diseases have surpassed hepatitis C as the leading causes of LT over the last decade, and have also risen as the underlying conditions seen in patients with HCC requiring LT. The United Network for Organ Sharing (UNOS) coordinates organ allocation, which includes disease severity, waitlist time, blood type, and distance from donor hospital. It has progressed to incorporate treatment response and alpha-fetoprotein into its listing criteria for patients with HCC, in addition to the well-established Milan Criteria (MC, one tumor <5 cm, ≤3 tumors ≤3 cm). Therapies to bridge patients until LT include locoregional therapies as well as immunotherapy. Dropout on the waitlist is seen up to 20% either due to decompensation or progression of disease. Recurrence of HCC post-transplant remains challenging. Given this, current guidelines recommend early palliative care involvement regardless of transplant listing status for both symptom management and advance care planning.
    Conclusions: For patients with HCC with favorable tumor biology, LT can be curative. However, given the symptom burden while awaiting LT and the notable number of patients who are unable to receive a transplant, early palliative care is critical in appropriate management of HCC.

    Abstract Background: Nonalcoholic steatohepatitis-associated hepatocellular carcinoma (NASH-HCC) is the second-leading cause of liver transplantation (LT) performed for HCC. Despite this, little is known about the clinical characteristics and outcomes of NASH-HCC.
    Methods: Patients undergoing LT for HCC from 2001 to 2017 at a single center were reviewed. Outcomes of NASH-HCC (n = 51) were compared to other etiologies of HCC including hepatitis C (HCV) hepatitis B (HBV), and alcoholic liver disease (ALD). Outcomes of NASH-HCC were also compared to HCV in the direct-acting antiviral (DAA) era (2014-2017).
    Results: The frequency of NASH-HCC as the primary indication for LT in patients with HCC increased significantly during the study period from 4.4% (2001-2008) to 15.6% in 2017. NASH-HCC patients were significantly older (median age 65 vs. 60; P < 0.001) with significantly lower alpha-fetoprotein levels (7.5 vs. 26.5, P < 0.001) compared to other etiologies. The 1-, 3-, and 5-year overall survival of NASH-HCC was 92%, 86%, and 80%. Overall survival of NASH-HCC was not significantly different compared to HCV, HBV, or ALD. Compared to HCV-HCC in the DAA era (n = 99), NASH-HCC had comparable post-LT survival (3-year survival 87% vs. 86%, P = 0.870).
    Conclusion: In this large single-center experience of NASH-HCC, we demonstrate favorable outcomes of NASH-HCC following LT comparable to other common etiologies of HCC.

    Abstract Liver transplant (LT) is the most favorable treatment option for patients with early stage hepatocellular carcinoma (HCC). Numerous attempts have been pursued to establish eligibility criteria and select HCC patients for LT, leading to various systems that essentially integrate clinico-morphological variables. Lacking of sufficient granularity to recapitulate the biological complexity of the disease, all these alternatives display substantial limitations and are thus undeniably imperfect. Liquid biopsy, defined as the molecular analysis of circulating analytes released by a cancer into the bloodstream, was revealed as an incomparable tool in the management of cancers, including HCC. It appears as an ideal candidate to refine selection criteria of LT in HCC. The present comprehensive review analyzed the available literature on this topic. Data in the field, however, remain scarce with only 17 studies. Although rare, these studies provided important and encouraging findings highlighting notable prognostic values and supporting the contribution of liquid biopsy in this specific clinical scenario. These results underpinned the critical and urgent need to intensify and accelerate research on liquid biopsy, in order to determine whether and how liquid biopsy may be integrated in the decision-making of LT in HCC.

    Abstract Immune checkpoint inhibitors (ICIs) have improved the management of patients with intermediate- and advanced-stage HCC, even making some of them potential candidates for liver transplantation. However, acute rejection has been observed after ICI therapy, challenging its safety in transplant settings. We summarize the key basic impact of immune checkpoints on HCC and liver transplantation. We analyze the available case reports and case series on the use of ICI therapy prior to and after liver transplantation. A three-month washout period is desirable between ICI therapy and liver transplantation to reduce the risk of acute rejection. Whenever possible, ICIs should be avoided after liver transplantation, and especially so early after a transplant. Globally, more robust prospective data in the field are required.
