Anthracyclines in the treatment of malignancy in pregnancy.

This article reports two cases and reviews the literature regarding chemotherapy using anthracyclines during pregnancy. Twenty-six additional cases using this class of agents to treat malignancy during pregnancy are summarized from 18 reports for a total of 28 pregnancies. Final outcome of pregnancy is analyzed with regard to the following factors: diagnosis, gestational age at start of therapy, total dose of anthracycline, number and type of agents used, neonatal pathologic findings and months of follow-up of infants. Final outcome of 28 pregnancies resulted in 24 normal infants including a set of twins in the current report. Limited pharmacokinetic information is inconclusive with regard to the appearance of anthracyclines and their known metabolites in placental or fetal tissue.
