Background: While recurrent hepatocellular carcinoma (HCC) after liver transplantation (LT) portends a poor prognosis, adjuvant therapy may prolong survival. We sought to identify factors that impact time to recurrence and mortality after recurrence, thus stratifying patients to guide treatment.
Methods: Retrospective analysis of 856 recipients undergoing LT for HCC from 1984 to 2014 identified 106 patients with recurrent tumor. A multivariate Cox regression identified factors affecting time to recurrence and mortality.
Results: Of 106 patients with recurrence, the median time to recurrence and survival after recurrence were 15.8 months (IQR 6.8-33.1) and 10.3 months (IQR 3.8-20.2), respectively (Figure 1), with 19 patients alive (median survival 27.5 months, five 5-year survivors).Multivariate predictors of time to recurrence and mortality are listed in Table 1 and Table 2, respectively.
