Abstract

Twenty-seven consecutive Italian patients with Fanconi's anaemia (FA) underwent stem cell transplantation (SCT) from an HLA-matched related donor in 10 Italian centres of the Associazione Italiana Ematologia ed Oncologia Pediatrica (AIEOP). Gruppo Italiano di Trapianto di Midollo Osseo (GITMO). Twenty-two patients (81.5%) were conditioned with low-dose (median 20 mg/kg) cyclophosphamide (Cy) and thoraco-abdominal or total body irradiation (median dose 500 cGy), five patients (18.5%) with high-dose Cy (median 120 mg/kg). Graft-vs.-host disease (GVHD) prophylaxis was carried out with cyclosporin A in 26 cases; methotrexate (MTX) was added in eight cases. One patient received MTX alone, The median follow-up was 36 months. Ninety-two percent of patients (25 out of 27) engrafted, grade II and III acute GVHD occurred in 28% and 8% of patients, respectively with chronic GVHD in 12.5%. Conditioning-related toxicity was mild: 4% of patients had grade III mucositis, 7.4% had grade II haemorrhagic cystitis. 14.8% had grade III liver toxicity and 11.1% had grade III renal toxicity. Transplant-related mortality at 12 months was 19.2%, survival at 36 months was 81.5%, with a median Karnofsky score of 100%. No late tumours occurred after a mean follow-up of the survivors of 5 years. None of the studied variables significantly affected the survival, including conditioning regimen, acute GVHD and clinical nonhaematological phenotype. Among the studied variables, only conditioning regimens containing high-dose Cy and the presence of genital abnormalities were significantly (P < 0.05) associated with an increased rate of acute GVHD. Our study demonstrates that the Italian FX patients undergoing SCT from an HLA-matched related donor have a very good outcome, These patients, when compared with others of different ethnic origin who underwent allogeneic bone marrow transplantation, showed a less severe nonhaematological phenotype, raising the possibility that this milder phenotype may have, at least in part, contributed to the outcome. Our data may provide a useful tool for further studies aiming to correlate genotype with phenotype.
