Doxorubicin and ifosfamide for high-grade sarcoma during pregnancy

Abstract

Purpose Doxorubicin and ifosfamide are highly active drugs for the treatment of high-grade sarcomas, but little is known on the optimal management of young patients who develop such malignancies during pregnancy. Methods We report on a single-institution series of patients ( n = 9) with high-grade sarcoma diagnosed during the third trimester of pregnancy. Neoadjuvant chemotherapy combining doxorubicin (50 mg/m^2 day 1) and ifosfamide (2.5 g/m^2 days 1–2) with standard mesna rescue every 3 weeks was administered during the third trimester of pregnancy in five patients. Results We observed a favourable outcome for both the mother and the offspring in all cases. Maternal and neonatal pharmacokinetic data for ifosfamide were obtained from one patient and did not evidence a transplacental transfer of this drug. The use of other active drugs (cisplatin, etoposide, dactinomycin and cyclophosphamide) in sarcoma during pregnancy is discussed on the basis of a comprehensive review of the English literature. Conclusions In view of this single-centre experience, we suggest that the treatment of high-grade sarcoma during the third trimester of pregnancy should include an adapted regimen tailored to the pharmacological specificities of the pregnant patients.
