Abstract

We report successful pregnancies in two young women (aged 24 and 20 years) following allogeneic bone marrow transplantation (BMT) for acute non-lymphoblastic leukaemia. Conditioning therapy consisted of cyclophosphamide (120 mg/kg) and total body irradiation (TBI, 12 Gy) in 2 Gy fractions once daily for 6 days or twice daily for 3 days. Graft-versus-host disease prophylaxis was with methotrexate alone. Both women were amenorrhoeic after BMT and gonadal testing indicated hypergonadotrophic hypogonadism. Both women had normal pregnancies (2 years and 5 years after BMT) resulting in normal healthy infants. Previously successful pregnancy has been reported after TBI in three women in whom the TBI dose was less than 8 Gy. Our cases illustrate that normal outcome of pregnancy is possible at even higher doses of TBI.
