ABSTRACT
Bone marrow transplantation (BMT) represents a potentially curative treatment of thalassemia. For patients without an HLA-identical sibling donor, recourse to an unrelated donor is a practicable option but the candidates and their families are faced with a difficult decision. They can either choose to continue the supportive therapy, with no chance of definitive cure, or they accept the mortality risk of BMT in the hope of obtaining a definitive resolution of the disease. We investigated the communication strategies and the post transplantation quality of life (QoL) in 19 adult thalassemia patients surviving after an unrelated donor BMT. The patients were given two questionnaires: a questionnaire to evaluate pre-transplantation communication factors and the EORTC QLQ-C30 questionnaire to assess global QoL. All patients were satisfied with the communication modalities employed by the physicians. The global post transplantation QoL in our patient cohort was found to be good. The approach used in this study may offer a contribution to understanding the decision-making process leading to the choice of a treatment with a high mortality risk for a chronic, non-malignant disease. Finally, some ethical issues of this therapeutic approach are briefly addressed.

Allogeneic SCT remains the only potential cure for patients with thalassemia. However, most BMT candidates lack a suitable family donor and require an unrelated donor (UD). We evaluated whether BMT using UDs in high-risk adult thalassemia patients can offer a probability of cure comparable to that reported employing an HLA-compatible sibling as donor. A total of 27 adult thalassemia patients (15 males and 12 females, median age 22 years) underwent BMT from a UD selected by high-resolution HLA molecular typing. The conditioning regimen consisted of Busulphan (BU, 14 mg/kg) plus Cyclophosphamide (CY, 120 or 160 mg/kg) in 12 cases and BU (14 mg/kg), Thiotepa (10 mg/kg) and CY (120-160 mg/kg) in the remaining 15 cases. Cyclosporine-A and short-term Methotrexate were used for graft-versus-host disease (GVHD) prophylaxis. In all, 19 patients (70%) are alive and transfusion-independent after a median follow-up of 43 months (range 16-137). A total of 10 patients (37%) developed grade II-IV acute GVHD and six (27%) chronic GVHD. Eight patients (30%) died from transplant-related causes. UD-BMT can cure more than two-thirds of adult thalassemia patients, and is a particularly attractive option for patients who are not compliant with conventional treatment.
