Abstract

AIMS: The aim of this study was to identify predictors of both survival and tumor-free survival of a cohort of 155 patients, with hepatocellular carcinoma (HCC) and cirrhosis, who were treated by orthotopic liver transplantation (OLT). METHODS: From January 1989 to December 2002, 603 OLTs were performed in 549 patients. HCC was diagnosed in 116 patients before OLT and in 39 at histological examination of the explanted livers. Eighty-four percent of the patients met "Milan" criteria at histology. Ninety-four patients received anticancer therapies preoperatively. RESULTS: The median follow-up was 49 months (range, 0-178). Overall, 1-, 3-, 5-, and 10-yr survival were 84%, 75%, 72%, and 62%, respectively. Survival was not affected by the patient's age or sex, etiology of liver disease, Child score at transplantation, rejection episodes, tumor number, total tumor burden, bilobar tumor, and pathologic Tumor, Nodes, Metastasis (pTNM) stages. There was no statistically significant difference in survival when patients were grouped according to the recently proposed simplified pTNM staging (5-yr survival, 80% in stage I, 69% in stage II, 50% in stage III, p= 0.3) or the United Network for Organ Sharing (UNOS) staging system for HCC. Encapsulation of the tumor and α-fetoprotein levels significantly affect patient survival. Five-year survival of patients with poorly differentiated (G3) HCC was significantly worse than that of patients with moderately (G2) or well-differentiated (G1) HCC (respectively, G3 44%, G2 67%, and G1 97%, p= 0.0015). Patients with micro- or macro-vascular invasion had a worse 5-yr survival than patients without vascular invasion (49%vs 77%, p= 0.04). Multivariate analysis showed that histological grade of differentiation and macroscopic vascular invasion are independent predictors of survival (HR 2.4, 95% CI 1.4-4.1, p= 0.0009 and HR 2.8, 95% CI 1.2-6.8, p= 0.022). CONCLUSION: Histological grade of differentiation and macroscopic vascular invasion, as assessed on the explanted livers, are strong predictors of both survival and tumor recurrence in patients with cirrhosis who received transplants for HCC.
