Purpose
To identify prognostic factors after hepatocellular carcinoma (HCC) recurrence after liver transplantation (LT).
Methods
We retrospectively reviewed the combined experience at Toronto General Hospital and Hospital Vall d’Hebron managing HCC recurrence after LT (n = 121) between 2000 and 2012. We analyzed prognostic factors by uni- and multi-variate analysis. Median follow-up from LT was 29.5 (range 2–129.4) months. Median follow-up from HCC recurrence was 12.2 (range 0.1–112.5) months.
Results
At recurrence, 31.4 % were treated with curative-intent treatments (surgery or ablation), 42.1 % received palliative treatment, and 26.4 % received best supportive care. The 1-, 3-, and 5-year survivals, respectively, after HCC recurrence were 75, 60, and 31 %, vs. 60, 19, and 12 %, vs. 52, 4, and 5 % (p < 0.001). By multivariate analysis, not being amenable to a curative-intent treatment [hazard ratio (HR) 4.7, 95 % confidence interval (CI) 2.7–8.3, p < 0.001], α-fetoprotein of ≥100 ng/mL at the time of HCC recurrence (HR 2.1, 95 % CI 1.3–2.3, p = 0.002) and early recurrence (<12 months) after LT (HR 1.6, 95 % CI 1.1–2.5, p = 0.03) were found to be poor prognosis factors. A prognostic score was devised on the basis of these three independent variables. Patients were divided into three groups, as follows: good prognosis, 0 points (n = 22); moderate prognosis, 1 or 2 points (n = 84); and poor prognosis, 3 points (n = 15). The 1-, 3-, and 5-year actuarial survival for each group was 91, 50, and 50 %, vs. 52, 7, and 2 %, vs. 13, 0, and 0 %, respectively (p < 0.001).
Conclusions
Patients with HCC recurrence after transplant amenable to curative-intent treatments can experience significant long-term survival (~50 % at 5 years), so aggressive management should be offered. Poor prognosis factors after recurrence are not being amenable to a curative-intent treatment, α-fetoprotein of ≥100 ng/mL, and early (<1 year) recurrence after LT.
