Pregnancy outcome in women treated with doxorubicin for childhood cancer

OBJECTIVE: Pregnancy outcome and the effect of pregnancy on cardiac function were assessed in women cured of childhood cancer. STUDY DESIGN: Forty women who received doxorubicin as part of a chemotherapy protocol for a neoplastic disorder in childhood were followed up at the same center during pregnancy and after delivery. RESULTS: Thirty-seven women (72 pregnancies) completed follow-up. Pregnancy outcome was favorable in the 29 women with fractional shortening values of greater than or equal to30% before pregnancy, and their myocardial function was sustained. In 8 women with fractional shortening of <30% before pregnancy, pregnancy outcome was less favorable; a 19% decrease in fractional shortening was observed after pregnancy, and this finding was not significant (P = .08). CONCLUSION: Pregnancy outcome in women who received doxorubicin for malignancy in childhood is generally favorable. However, those with baseline left ventricular dysfunction should be considered at increased risk for worse pregnancy outcome and further deterioration in myocardial function.
