There are very few reports in the literature of successful pregnancy following allogeneic transplantation for Fanconi anaemia (FA). Despite attenuation of conditioning, transplantation causes significant germ cell injury and is generally considered to induce secondary infertility. Goi et al (2006) recently reported a patient presenting with menorrhagia aged 19 years, subsequently found to be pancytopenic due to FA. She received an allogeneic transplantation from her human leukocyte antigen (HLA)-matched sister and re-started regular menstruation at 6 months post-transplant. She went on to conceive naturally 48 months post-transplant and delivered a healthy child. The one other case described is of a patient with FA transplanted from her HLA-matched sibling at aged 17 years (Dalle et al, 2004). The patient had experienced spontaneous menarche aged 11 years, followed by regular periods. Secondary amenorrhoea was evident by 18 months post-transplant, although it is unclear what replacement therapy was instigated. She subsequently carried two natural pregnancies and delivered two healthy children. We report a female patient initially diagnosed with FA aged 8 years. She underwent HLA-matched allogeneic bone marrow transplantation from her sibling aged 10 years, conditioned with Cyclophosphamide 20 mg/kg total dose, total body irradiation (TBI) over 4 d (4 Gy total dose) and antithymocyte globulin (60 mg/kg total dose). The procedure was tolerated extremely well and she did not develop graft-versus-host disease. She entered puberty spontaneously aged 12 years with normal menstrual cycles. She became pregnant naturally 13 years and 16 years post-transplant and delivered two healthy children after uncomplicated pregnancies monitored in collaboration with the Late Effects and Obstetric clinics at our institution. Clearly, despite the significant doubts that transplant and reproductive specialists may harbour, successful natural pregnancy is realistic in patients with FA following allogeneic haemopoietic transplantation, even when myeloablative (TBIcontaining) conditioning is used. Significantly, this is the first report of successful pregnancies in a patient with FA transplanted in the pre-pubertal period with preservation of fertility. We recommend patients transplanted for FA should be appropriately counselled in relation to family planning and contraception, and ideally managed within a multidisciplinary Late Effects clinic.
