Cancer in Pregnancy: Mitoxantrone
Mitoxantrone (Novantrone) is 1,4-dihydroxy-5,8-bis ((2-((2-hydroxyethyl)amino)ethyl)amino)anthraquinone, often abbreviated DHAQ. It is an antineoplastic agent that appears to bind DNA and produce strand scission 1,2.
|In vitro studies||mammalian assay systems||Mitoxantrone is genotoxic in several mammalian assay systems 3-5.|
|Animal studies *||Rabbits||up to 0.4 mg/kg/day||We have been unable to locate references on possible developmental toxicity of mitoxantrone; however, ametantrone, a similar agent, was teratogenic in rabbits at doses of 0.4mg/kg/day but not at 0.2 mg/kg/day 6.|
|Rats||up to 6 mg/kg/day||Ametantrone was not teratogenic in rats at up to 6 mg/kg/day 6.|
|Human studies||Case reports||2nd trimester Combination with: cytarabine + idarubicin||Two case reports have described the use of mitroxantrone during the second trimester of human pregnancy 7,8. In one case, five weeks of therapy with mitroxantrone and cytarabine up to developmental week 28 were accompanied by normal fetal growth 7. Subsequent introduction of idarubicin to replace mitroxantrone was followed by death of the fetus. In the second case, a mother treated with a variety of chemotherapeutic agents including mitroxantrone from 24 to 34 weeks of gestation delivered a normal female infant 8.|
|Breast feeding||Pharmacokinetic||Mitoxantrone is excreted in breast milk in small amounts 8.|
|Case reports||Based on data from one lactating mother, this agent is apparently stored and released slowly into breast milk for at least one month after its administration 8. Although the quantities of drug in milk were very low (10-20 ng/mL), breastfeeding was not recommended in this case.|
