Milan criteria versus San Francisco criteria in hepatocellular carcinoma: our center's experience.
OBJECTIVE
Liver transplantation (OLT) represents the best treatment for hepatocellular carcinoma (HCC) in advanced cirrhosis showing a 70% 5-year survival rate. Our study sought to compare overall survivals among patients who underwent OLT under Milan Criteria (MC) or San Francisco Criteria (UCSFC).


METHODS
We retrospectively analyzed patients who underwent liver transplantation for HCC in our institution from November 2001 to December 2007. We analyzed age, gender, OLT indication, maximal tumor size, histology, and survival. We compared survival among patients who met MC versus UCSFC.


RESULTS
From November 2001 to December 2007, 48/177 (27%) liver transplantations performed in our hospital were indicated due to HCC. The two patients who did not show any tumor in the explanted liver (false-positive ratio 4.2%) were excluded from the analysis. Another two patients were included who showed incidental HCC lesions (false-negative ratio 1.7%), yielding 48 analyzed patients. The mean diameter of the HCC nodules were 3.1 cm before OLT and 3.8 cm in the pathologic examination, a statistically significant difference. Two patients exceeded MC before OLT, and six patients showed this feature in the explanted liver. There was a significant difference in the degree of vascular invasion between the two groups. Overall mortality was 25.9% at 4 years; the MC group show an 11.9% versus UCSFC group, a 66.6% rate.


CONCLUSIONS
HCC is a common indication for OLT. Hepatitis C virus is the most common etiology. Survival among the MC group was significantly better than that of subjects beyond the MC, a difference that supports the use of MC for HCC.
