Abstract
Purpose
This study was designed to analyze the clinical results in patients suitable for liver transplantation with hepatocellular carcinoma (HCC) who exceeded Milan criteria, which underwent intra-arterial therapies (IAT), to determine predictive factors of successful downstaging.
Methods
A total of 277 consecutive patients with cirrhosis and HCC were treated by IAT (transarterial oily chemoembolization, transarterial chemoembolization, transarterial embolization) in a single center. Eighty patients exceed the Milan criteria. Patients with infiltrative HCC, hypovascular HCC, and portal vein thrombosis were excluded, with a final study population of 48 patients. Tumor response to IAT was evaluated with CT and/or MRI according to modified RECIST criteria. Successful downstaging was defined as a reduction in the number and size of viable tumors to within the Milan criteria, and serum alpha-fetoprotein (AFP) <100 ng/mL, for at least 6 months.
Results
Nineteen patients (39 %) had their tumors successfully downstaged; 29 patients (61 %) did not. Multivariate analysis showed that AFP level <100 ng/mL and 3-year calculated survival probability using the Metroticket calculator were the only independent predictors of successful downstaging (p < 0.023 and p < 0.049 respectively).
Conclusions
Biological characteristics of HCC as AFP levels <100 ng/mL and high 3-year calculated survival probability may predict a good response to downstage after IAT.
