*Purpose: Early recurrence of hepatocellular carcinoma (HCC) after liver transplantation (LT) carries a poor prognosis. We aimed to develop a risk score for early HCC recurrence using pre-LT variables.
*Methods: Adults undergoing LT for HCC from 2001-2015 from 6 large centers were reviewed. Competing risk regression was used to identify predictors of early HCC recurrence (≤ 1 year).
*Results: Of 3235 patients, 459 developed HCC recurrence (14.2%), including 175 (38%) recurrences within 1 year of LT. Independent pre-LT predictors of early HCC recurrence included initial tumor size > 3 cm, ≥ 3 pre-LT locoregional therapies, pre-LT neutrophil-to-lymphoycte ratio > 5, and alpha-fetoprotein response. The “early recurrence risk score” was created using hazard ratios and resulted in low (0 points), low-medium (2-4 points), medium-high (5-8 points), and high (>8 points) risk groups (Fig 1). The probability of recurrence at 1-year in the low-risk group was 1.8% vs. 44.9% in the high-risk group (P<0.001) (Fig 2). When stratified according to risk score, those at low-risk for early HCC recurrence had a 5-year overall survival of 80% vs. 40% in the high-risk group (P<0.001) (Fig 2).
*Conclusions: The score provides a risk stratification model for early (≤ 1year) recurrence in patients with HCC undergoing LT. It will benefit in the selection criteria and identify candidates with aggressive tumor biology with poor posttransplant cancer outcomes.
