RESUMEN
The Australasian Bone Marrow Transplant Recipient Registry (ABMTRR) commenced collecting data on hematopoietic stem cell transplantation (HSCT) in 1992, and by 2004 had accrued more than 12,000 transplant records from 44 centers. In 2004 the Australian annual per capita autograft activity rate was almost twice that of New Zealand (381 per 10 million compared to 195), whereas the 2 countries had similar allografting activity rates (Australia 145, New Zealand 133). The annual rates of allogeneic HSCT per 10 million population in Australia and New Zealand in 2004 were similar to those in European countries of comparable socioeconomic status. Among the most prominent trends between 1998 and 2004 were increases in the numbers of allogeneic HSCT using peripheral blood stem cells (PBSC), the emergence of reduced intensity conditioning in allogeneic HSCT, increases in numbers of autologous HSCT for recipients aged 60 and over, increases in allogeneic HSCT with unrelated donors, and decreases in numbers of allogeneic HSCT for chronic myelogenous leukemia and autologous HSCT for breast cancer. The cumulative incidence of transplant-related mortality (TRM) at 100 days posttransplant progressively fell over the years 1992 to 2003 and was 8.1% for allogeneic HSCT and 1.1% for autologous HSCT in 2003. The ABMTRR is a valuable data resource providing timely and accurate information on HSCT activity in Australia and New Zealand. Full enumeration of HSCT activity in the 2 countries by the ABMTRR enhances its value in clinical planning and management.
