ABSTRACT
BACKGROUND: The Austrian Bone Marrow Donor Registry is the central search coordinating unit in charge of national and international donor searches in Austria. PATIENTS AND METHODS: Between 1988 and 2010, a worldwide search for an unrelated donor of blood stem cells (URD) was initiated for 2,166 Austrian patients with haematological disorders, 1,671 adults and 495 children, by the Austrian Bone Marrow Donor Registry. RESULTS: An URD was identified for 78.3% of the patients between 2008 and 2010, for 76.7% of the patients between 2004 and 2007, for 71.3% between 1996 and 2003, but only for 53.4% of the patients in the initial period of 1988-1995. Thus, results of international donor searches improve over time. In contrast, search duration decreases steadily: Search times of successful searches decreased from about 8 months in the first period between 1988 and 1996 to 1.84 months in 2010. Overall, 1,558 of the 2,166 patients (71.9%) could be provided with a matching donor. However, not every patient provided with a URD was transplanted. Overall, only 1,141 of 2,166 patients (52.7%) proceeded to transplant. CONCLUSION: Figures have significantly improved for the latest period of donor searches between 2008 and 2010. In this period, a donor could be found for 78.3%, and 58.5% of the patients received a transplant.
