Clinical Report: Long-term Outcomes of Adult Liver Transplant Recipients Over 40 Years
Overview
This retrospective study analyzed 491 adult liver transplant recipients over 40 years at a single Italian institution, comparing patients surviving more than 10 years post-transplant with those who did not. Key factors influencing long-term survival were identified, providing insights into improving post-transplant outcomes.
Background
Liver transplantation (LT) is the definitive treatment for various acute and chronic liver diseases and hepatic tumors. Since its inception in 1963 and recognition as standard therapy in 1983, LT programs have expanded globally, with improved surgical techniques and immunosuppression enhancing survival rates. While short- and mid-term outcomes are well documented, data on long-term survival beyond 10 years remain limited. This study aims to fill that gap by evaluating long-term outcomes and factors limiting survival after LT.
Data Highlights
A total of 777 patients underwent 818 liver transplants between May 1982 and May 2022; after exclusions, 491 adult patients were analyzed. Patients were categorized into Long Surviving Group (>10 years survival) and Short Surviving Group (<10 years). Data collected included recipient and donor demographics, transplant characteristics, immunosuppression regimens, and clinical status per UNOS classification. Survival rates have improved from historical 5-year survival of 50% to recent 5- and 10-year survival rates of 70–75% and 50–60%, respectively.
Key Findings
Long-term survival (>10 years) after LT has progressively increased over the past four decades.
Recipient factors such as age, underlying liver disease etiology, and UNOS status significantly influence long-term survival.
Donor-recipient matching, including blood group and sex, impacts transplant outcomes.
Advances in immunosuppressive therapy and perioperative care have contributed to improved survival rates.
Primary non-function and primary dysfunction remain critical early complications affecting survival.
Patients transplanted before 2012 with complete follow-up data were included to ensure adequate long-term outcome assessment.
Clinical Implications
Clinicians should consider recipient and donor characteristics carefully to optimize long-term outcomes after LT. Continuous advancements in immunosuppression and perioperative management are essential to further improve survival. Monitoring and managing early graft dysfunction remain priorities to enhance patient prognosis.
Conclusion
This extensive single-center experience highlights significant improvements in long-term survival after liver transplantation and identifies key factors associated with outcomes. These findings support ongoing efforts to refine patient selection and post-transplant care to maximize longevity.
