Hepatocellular carcinoma (HCC) is a leading cause of cancer death, with liver transplantation (LT) offering a curative option for early-stage patients who cannot undergo resection. Although LT provides good long-term outcomes within standard criteria, recurrence occurs in approximately 8–20% of recipients and often leads to poor survival. Traditionally, LT eligibility relied on strict criteria like the Milan criteria, which are effective in selecting patients with low recurrence but may exclude patients who could benefit from transplantation. In response, new expanded criteria and models using tumor biology have been developed for better risk stratification, allowing more personalized selection and management. Despite these advances, recurrence remains a major clinical challenge, with no consensus on optimal imaging timing or frequency post-LT. Treatment depends on the recurrence’s extent and location, including surgical resection and locoregional therapies. Systemic treatments are promising, especially for unresectable or extrahepatic recurrence, though most evidence comes from small retrospective studies, limiting the development of standardized protocols. Future research should focus on addressing these gaps and guiding evidence-based post-transplant care. This is a narrative review summarizing recent advances in HCC recurrence.

Bridging locoregional therapy (LRT) is widely used in liver transplant (LT) candidates with hepatocellular carcinoma (HCC) to minimize waitlist dropout and evaluate tumor biology. While transarterial chemoembolization (TACE) has historically been the predominant approach, the role of transarterial radioembolization (TARE) is expanding. Comparative effectiveness data for these 2 modalities as bridging strategies remain limited. This study assessed the trends, factors influencing therapy selection, and outcomes of transarterial bridging LRT. We conducted a retrospective cohort study of adult LT candidates with HCC listed in the Organ Procurement and Transplantation Network (OPTN) between 2016 and 2024 who received TACE or TARE as their sole bridging LRT. Inverse probability weighting (IPW) was applied to balance baseline covariates. Multivariable Fine–Gray competing risk regression and stratified Cox proportional hazards and logistic regression models were used to assess waitlist dropout, complete pathological necrosis (CPN), recurrence, and overall survival. Among 8367 patients, 5472 (65%) received TACE, and 2895 (35%) received TARE. TARE use increased significantly from 22.5% to 51.7% over the study period. TARE was more likely to be used among patients with MASLD, older age, and high tumor burden, and less likely in those with lower socioeconomic status. TARE recipients had a significantly lower risk of waitlist dropout (sHR 0.83, p <0.001) and a higher likelihood of achieving CPN (aOR 2.24, p <0.001). The overall survival did not differ significantly between groups (aHR 0.94, p =0.19). The use of TARE as bridging therapy in HCC LT candidates has surged and is influenced by socioeconomic factors, comorbidities, and tumor burden. TARE effectiveness has been demonstrated by its advantages in waitlist retention and tumor necrosis. Further studies are warranted to evaluate its impact on post-LT recurrence and to validate the cost-effectiveness among transarterial therapies.

Autoimmune hepatitis (AIH) is a varied inflammatory chronic liver disease. AIH’s prevalence varies and has increased recently. Diagnosis involves the discovery of histologic features following liver biopsy and serologic testing. Clinical features vary, and up to 40% of patients may be asymptomatic. Evaluating thiopurine methyltransferase (TMPM) activity before treatment is crucial for an optimal response. The primary treatment goal is biochemical remission, normalized serum IgG, and liver enzymes. Induction therapy typically involves azathioprine and corticosteroids. Close monitoring of liver function tests and serum immunoglobulin levels is essential. Medications can be tapered after achieving biochemical remission. Liver transplantation may be required for refractory disease or cirrhosis. Further therapeutic approaches are needed, particularly for non-responders to first-line treatments.

Objectives: Acute liver failure (ALF) is associated with high morbidity and mortality. Timely liver transplantation (LT) is the only universally accepted therapy for ALF that is non-responsive to medical therapy. Data regarding the use of living donor LT (LDLT) for this indication in the US is scarce. Materials and Methods: United Network of Organ Sharing/Organ Procurement and Transplantation Network (UNOS/OPTN) data from January 2002 to December 2020 were reviewed. Adult and pediatric recipients listed as status 1 were included. Demographics, clinical and laboratory data, and post-LT survival rates were compared for LDLT vs. DDLT recipients. Results: There were 180 LDLT (3.6%) and 4779 DDLT (96.4%) recipients with a diagnosis of ALF. The majority of recipients in the LDLT group were pediatric (n = 164, 91%) compared to the DDLT group (n = 1455, 30%), p < 0.001. In the pediatric-only group, post-LT survival was comparable between LDLT and DDLT recipients (p = 0.15). Five-year post-LT survival was higher for pediatric recipients compared to adults in the LDLT group (84.2% vs. 62.5%, respectively, p < 0.001) and the DDLT group (82.8% vs. 78.7%, respectively, p < 0.001). Adults had a higher hazard of death compared to pediatric recipients in the LDLT group (HR = 3.560, 95% CI 1.612–7.844, p = 0.002) and the DDLT group (HR = 1.472, 95% CI 1.290–1.679, p < 0.001). In multivariate analysis results, the type of LT and age group were not associated with higher post-LT mortality. Conclusions: In the US, LDLT constitutes 3.6% of LTs for ALF. In the pediatric-only group, post-LT survival was comparable between LDLT and DDLT recipients. Overall, there were superior post-LT outcomes for pediatric recipients compared to adults for LDLT and DDLT.

(1) Background: Hepatocellular carcinoma (HCC) contributes to the significant burden of cancer mortality in the United States (US). Despite highly efficacious antivirals, chronic viral hepatitis (CVH) remains an important cause of HCC. With advancements in therapeutic modalities, along with the aging of the population, we aimed to assess the contribution of CVH in HCC-related mortality in the US between 1999–2020. (2) Methods: We queried all deaths related to CVH and HCC in the multiple-causes-of-death files from the CDC Wide-ranging Online Data for Epidemiologic Research (WONDER) database between 1999–2020. Using the direct method of standardization, we adjusted all mortality information for age and compared the age-adjusted mortality rates (AAMRs) across demographic populations and by percentile rankings of social vulnerability. Temporal shifts in mortality were quantified using log-linear regression models. (3) Results: A total of 35,030 deaths were identified between 1999–2020. The overall crude mortality increased from 0.27 in 1999 to 8.32 in 2016, followed by a slight reduction to 7.04 in 2020. The cumulative AAMR during the study period was 4.43 (95% CI, 4.39–4.48). Males (AAMR 7.70) had higher mortality rates compared to females (AAMR 1.44). Mortality was higher among Hispanic populations (AAMR 6.72) compared to non-Hispanic populations (AAMR 4.18). Higher mortality was observed in US counties categorized as the most socially vulnerable (AAMR 5.20) compared to counties that are the least socially vulnerable (AAMR 2.53), with social vulnerability accounting for 2.67 excess deaths per 1,000,000 person-years. (4) Conclusions: Our epidemiological analysis revealed an overall increase in CVH-related HCC mortality between 1999–2008, followed by a stagnation period until 2020. CVH-related HCC mortality disproportionately affected males, Hispanic populations, and Black/African American populations, Western US regions, and socially vulnerable counties. These insights can help aid in the development of strategies to target vulnerable patients, focus on preventive efforts, and allocate resources to decrease HCC-related mortality.

Objectives: Cholangiocarcinoma (CCA) is a malignancy of the biliary epithelium associated with high mortality. Hepatocellular carcinoma (HCC) is the most common primary liver tumor and has an established indication for liver transplant (LT). Living-donor LT (LDLT) may offer a curative and timely option for selected CCA patients. Methods: The United Network of Organ Sharing/Organ Procurement and Transplantation Network (UNOS/OPTN) data was reviewed from January 2010 to December 2022 for patients who underwent LDLT with HCC or CCA diagnostic codes. Post-LDLT survival for CCA was compared to HCC and non-HCC/CCA patients using Kaplan–Meier analysis. Stepwise multivariate analysis adjusted for recipient age, gender, race, and underlying etiology. Results: LDLT for CCA was most commonly performed in UNOS region 7 (54.9%) and region 2 (12.7%). Among 3993 LDLT recipients, 102 (2.6%) had CCA, 774 (19.4%) had HCC, and 3117 (78%) had neither HCC nor CCA. The 1-, 3- and 5-year post-LDLT survival of patients with CCA were 84.6%, 70.4%, and 62.2% versus 93.1%, 85.2%, and 78.2% for HCC, respectively. Conclusions: CCA accounts for 2.6% of LDLTs compared to 19.4% for HCC in the United States. At 5 years post-LDLT, patients with CCA have significantly lower survival compared to HCC.
