Optimizing liver transplant prioritization for hepatocellular carcinoma through risk stratification

Area of Science:

• Hepatobiliary surgery
• Transplant surgery
• Oncology

Background:

• Current liver transplant allocation for hepatocellular carcinoma (HCC) in the US uses uniform exception points, overlooking individual dropout risk and transplant benefit.
• HCC heterogeneity necessitates improved risk stratification for patients meeting transplant eligibility criteria.

Approach:

• This review discusses the development of risk prediction models for HCC tailored for liver allocation.
• Examines limitations of existing models and their lack of clinical adoption.

Key Points:

• A nuanced allocation scheme is crucial for accurately reflecting transplant urgency in HCC patients.
• Improved risk stratification can optimize organ utility and post-transplant outcomes.
• The upcoming continuous distribution model for liver allocation presents an opportunity to refine HCC prioritization.

Conclusions:

• Enhanced risk stratification for HCC patients is vital for equitable liver transplant allocation.
• Future models should balance transplant urgency with potential patient benefit.
• Revising allocation schemes can lead to better outcomes for HCC patients awaiting liver transplants.
