Pregnancy Among Survivors of Childhood Cancer: Cardiovascular Considerations.

PURPOSE OF REVIEW: To educate clinicians on cardiovascular considerations and management strategies surrounding pregnancy in childhood cancer survivors. RECENT
FINDINGS: With advances in oncologic treatment, growing numbers of childhood cancer survivors are now able to consider pregnancy. A significant proportion of survivors have received cardiotoxic therapy, particularly anthracyclines, and/or chest radiation. Cardiomyopathy is the most common cardiac complication of cancer-directed therapy; pericardial disease, valvular disease, premature coronary artery disease, and conduction abnormalities are other potential sequelae. In female survivors of childhood malignancy, cardiac evaluation should be performed prior to pregnancy as subclinical disease has the potential to be unmasked by the hemodynamic stress of pregnancy. However, limited data exist on pregnancy outcomes after cancer survivorship. With appropriate management, maternal and fetal outcomes in pregnancy following childhood cancer are generally favorable. Further research is needed to understand the incidence of cardiac complications among childhood cancer survivors, strategies to prevent these complications, optimal cardiovascular management during pregnancy and the postpartum period, and on the impact of pregnancy itself on the natural history of treatment-related cardiotoxicity.
