The Authors discuss the utility of alpha-fetoprotein (AFP) determination in mediastinal dysembryomas. AFP should be determined in all cases of mediastinal lesion. High levels of up to 500 ng/ml are a sure sign of germ cell tumors. An extremely high level (greater than 1,000 ng/ml) is an indication that the lesion is a mesoblastoma. An increase in the AFP level in the follow-up of patients affected by germ cell tumors is a sure sign of the recurrence of the disease.

Abstract
The Authors discuss the utility of alpha-fetoprotein (AFP) determination in mediastinal dysembryomas. AFP should be determined in all cases of mediastinal lesion. High levels of up to 500 ng/ml are a sure sign of germ cell tumors. An extremely high level (greater than 1,000 ng/ml) is an indication that the lesion is a mesoblastoma. An increase in the AFP level in the follow-up of patients affected by germ cell tumors is a sure sign of the recurrence of the disease.
