RESUMO
Hepatocellular carcinoma (HCC) is the most common primary neoplasm of the liver, mainly secondary to cirrhosis caused by hepatitis C virus. Liver transplant (LT) is considered the best treatment because, in addition to removing the tumor, it also removes the underlying cirrhotic liver. The Milan criteria for LT have limitations because they do not consider the biological characteristics of the tumor. Thus, our objective was to evaluate the association of α-fetoprotein (AFP) levels before LT performed for HCC with recurrence of this tumor, and, based on the results, a new predictive model that combines the AFP values at the list entry with the usual criteria of tumor size and number of nodules was validated. In present study, the Score AFP model, we were able to correlate a greater occurrence of relapse with scores of 3 and 4 (Pâ¯=â¯.0001), indicating the usefulness of using AFP as a predictor of recurrence.

Hepatocellular carcinoma (HCC) is the sixth leading cause of cancer in the world, and liver transplant (LT) is a good therapeutic option in selected cases because it treats the neoplasm and the underlying disease. Recurrence after LT is usually aggressive and has low survival; thus, an adequate selection of recipients is ideal. The new models aim to assess the individual risk of HCC recurrence in patients undergoing LT and to improve post-LT survival. In this study, our aim was to assess the applicability of the "Metroticket" score, correlating it with our rates of recurrence and survival after LT. Overall survival at 5 years in our study differed from that in Metroticket 2.0 because that study did not consider only recurrence as the cause of death; our study evaluated only patients with recurrence, so we were able to validate the score as a predictor of greater tumor aggressiveness after LT.
