Hepatocellular carcinoma is an epithelial tumor derived from hepatocytes that accounts for more than 80% of all primary hepatic tumors. The severity of the underlying disease is almost always the key factor in deciding whether to consider liver resection or transplantation as its treatment. Data in our registry corresponding to almost 800 patients from transplant centers throughout the world showed that patient survival after liver transplantation was significantly affected by histologic grade, tumor size >5 cm, and the presence of positive nodes. Recurrence-free survival showed a correlation with tumor size >5 cm, positive nodes, bilobar spread, and vascular invasion. At the present time, 59% of patients in our registry are alive, 84% of whom are free of tumor. Of those who died, half did so without evidence of tumor.

Downstaging of hepatocellular carcinoma before liver transplantation: Results from a national multi-center prospective cohort study.
Hepatology
January 2025
Division of Gastroenterology and Hepatology, University of California, San Francisco, San Francisco, CA.
Background Aims: Patients with hepatocellular carcinoma (HCC) meeting UNOS-downstaging (DS) criteria have excellent post-liver transplantation (LT) outcomes. Studies on HCC beyond UNOS-DS criteria ("All-comers" (AC)) have been limited by small sample size and short follow-up time, prompting this analysis.
Approach Results: 326 patients meeting UNOS-DS and 190 meeting AC criteria from 9 LT centers across 5 UNOS regions were enrolled from 2015 to 2023 and prospectively followed.
Donation After Circulatory Death Liver Transplantation: Impact of Normothermic Machine Perfusion on Key Variables.
Anesth Analg
September 2024
From the Department of Anesthesiology and Perioperative Medicine, Mayo Clinic, Phoenix, Arizona.
Background: During orthotopic liver transplantation, allograft reperfusion is a dynamic point in the operation and often requires vasoactive medications and blood transfusions. Normothermic machine perfusion (NMP) of liver allografts has emerged to increase the number of transplantable organs and may have utility during donation after circulatory death (DCD) liver transplantation in reducing transfusion burden and vasoactive medication requirements.
Methods: This is a single-center retrospective study involving 226 DCD liver transplant recipients who received an allograft transported with NMP (DCD-NMP group) or with static cold storage (DCD-SCS group).
Pre-emptive treatment for cytomegalovirus viraemia to prevent cytomegalovirus disease in solid organ transplant recipients.
Cochrane Database Syst Rev
January 2025
Cochrane Kidney and Transplant, Centre for Kidney Research, The Children's Hospital at Westmead, Westmead, Australia.
Background: Cytomegalovirus (CMV) is a significant cause of morbidity and death in solid organ transplant recipients. Pre-emptive treatment of patients with CMV viraemia using antiviral agents has been suggested as an alternative to routine prophylaxis to prevent CMV disease. This is an update of a Cochrane review first published in 2006 and updated in 2013.

BACKGROUND We previously reported that the Model for End-stage Liver Disease (MELD) score and donor age are risk factors for small-for-size syndrome in adult living donor liver transplantation (LDLT) involving small grafts. Since April 2021, we have performed splenectomy as a portal inflow modulation in LDLT using small grafts according to the presence of risk factors. In this study, we evaluated the validity of our splenectomy strategies for optimizing graft outcomes.

Background: Predicting the efficacy of immune-based therapy in patients with unresectable hepatocellular carcinoma (HCC) remains a clinical challenge. This study aims to evaluate the prognostic value of the systemic immune-inflammation index (SII) in forecasting treatment response and survival outcomes for HCC patients undergoing immune-based therapy.
Methods: We analyzed a cohort of 268 HCC patients treated with immune-based therapy from January 2019 to March 2023.
