Abstract

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, 14mg/kg) plus Cyclophosphamide (CY, 120 or 160mg/kg) in 12 cases and BU (14mg/kg), Thiotepa (10mg/kg) and CY (120-160mg/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.
