Can we expand the indications for liver transplantation among hepatocellular carcinoma patients with increased tumor size?
BACKGROUND
Due to the scarcity of donors and the fact that size is the main prognostic factor, Milan criteria have been used since 1996 to select hepatocellular carcinoma (HCC) patients for liver transplantation. In 2001 UCSF criteria showed that including layer tumors did not reduce the survival results. The objective of this paper was to evaluate whether HCC tumor sizes exceeding the Milan criteria adversely influence survival rates.


METHODS
Between May 1988 and July 2001, 53 patients were transplanted due to HCC and cirrhosis. The etiology of cirrhosis was HCV in 23 cases and HBV in 6. In 11 cases the HCC were incidental by discovered namely, a mean/ diameter of 1.8 cm (versus 2.6 cm in nonincidental HCC). Sixty-two percent of tumors met the Milan criteria, and 68% the USCF criteria.


RESULTS
The actuarial survival was 79% at 1 year and 62% at 5 years. The survival of patients with incidental HCC was 82% at 1 year and 82% at 5 years, which is better than the survival of those with nonincidental HCC (78% at 1 year and 57% at 5 years, P<.05). According to Milan criteria, the survival patients with early tumors was 82% at 1 year and 68% at 5 years, and for advanced tumors (NS), 75% and 54%, respectively. Comparison of early versus advanced tumors according to UCSF criteria showed survivals of 84% versus 64% at 1 year (P<.05) and 67% versus 48% at 5 years (P<.05), respectively.


CONCLUSIONS
Increasing the HCC size among LT according to the California criteria did not reduce survival rates compared with the Milan criteria.
