The evolution of the liver transplant candidate

Area of Science:

• Hepatology
• Transplant Surgery
• Medical Ethics

Background:

• Human liver transplantation (LT) has transitioned from experimental to routine care over the past six decades.
• Indications for LT have evolved, with decreasing reliance on viral hepatitis and increasing focus on alcohol-related and metabolic liver diseases.
• Patient demographics are shifting towards older individuals with more comorbidities, alongside persistent challenges with donor organ availability.

Purpose of the Study:

• To review the evolution of indications for liver transplantation.
• To discuss current trends in liver transplant patient populations and organ allocation.
• To highlight the challenges and advancements in liver transplant medicine.

Main Methods:

• Review of historical data and current clinical practices in liver transplantation.
• Analysis of changing etiological factors for liver disease leading to transplantation.
• Examination of organ allocation strategies and prognostic models.

Main Results:

• Hepatitis B and C are less common indications due to improved treatments; alcohol-related and metabolic liver diseases are now primary drivers for LT.
• Emerging indications include acute on chronic liver failure, alcoholic hepatitis, and specific malignancies like colorectal cancer liver metastases.
• Donor organ shortage remains a critical barrier, necessitating transparent allocation systems and prognostic models to ensure equitable access.

Conclusions:

• Liver transplantation has matured into a standard treatment, but its application continues to evolve with changing disease patterns and patient profiles.
• Addressing the organ shortage and refining allocation strategies are crucial for maximizing the benefits of this life-saving procedure.
• Ongoing research into prognostic models and alternative therapies is essential for improving outcomes and access to liver transplantation.
