    Haematopoietic stem cell transplantation (HSCT) has progressed rapidly since its introduction about five decades ago. There is now an increasing demand for transplant physicians in both public and private domains to perform this procedure in view of significant improvement of remission rates in haematological malignancies and increasing indications of HSCT. Peripheral blood has largely replaced bone marrow as the preferred source of haematopoietic stem cells (HSC). Transplantation-related mortality and morbidity rates have considerably decreased because of improved conditioning regimens, human leukocyte antigen (HLA) typing methods, supportive care, and most importantly, prophylaxis, diagnosis and treatment of serious infections. New transplantation strategies, such as reduced intensity transplantation, have extended the use of allogeneic transplant to patients with older age and co-morbidities. Current efforts are focused on ways to increase the donor pool and to improve the long term outcome of HSCT survivors in particular to reduce the relapse rate and the late effects of HSCT. This article summarizes the sources and procurement of HSC, the types and process of HSCT, indications for HSCT and complications associated with HSCT with particular reference to the current practice within the local settings.

    Children who would benefit from a haematopoietic stem cell transplantation often lacked a compatible sibling donor. Unrelated cord blood transplantation was offered as an alternative donor source for patients with a variety of malignant and non-malignant diseases who had no further treatment options. Cord blood units were sourced from various international cord blood registries. The median nucleated and CD34+ cell doses were 8.7 x 10(7)/kg and 2.6 x 10(5)/kg respectively. In spite of adequate cell doses, a high rate of non-engraftment of 32% was observed. Acute graft-versus-host disease (GVHD) occurred in 14 out of the 15 patients who engrafted with 53% being grade III to IV GVHD. The five year disease free survival was 40.7% with infection and GVHD being the commonest causes of death. The five year disease free survival was 20.5% and 60.7% for malignant and non-malignant diseases respectively.

    We analysed the outcome of 104 patients from a single institution who underwent allogeneic haematopoietic stem cell transplantation (AHSCT) from their HLA-identical siblings between 1993 and 2006. Sixty-nine percent of patients had peripheral blood stem cell (PBSC) as the stem cell source and the remaining had bone marrow (BM). The majority of patients are Chinese (60%) followed by Malays (24%) and Indians (14%). The median time to reach white cell counts of >1 x 10(9)/L and platelet counts of >30 x 10(9)/L was 13 and 15 days, respectively in patients who had PBSC transplantation compared with 16 and 25 days in patients who had BM transplantation, (p < 0.0001 and p < 0.001). Acute graft-versus-host disease (aGVHD) of grade II to IV was observed in 34% of patients and chronic graft-versus-host disease (cGVHD) in 38% of patients. Although not statistically significant, there was a higher incidence of overall aGVHD in Indian patients (73%) compared to Chinese and Malays (57% and 56% respectively). There was no significant difference in the incidence of aGVHD and cGVHD with the source of stem cells. Overall survival (OS) and disease free survival (DFS) was 50% and 60% at five years respectively. Multivariate analysis showed that patients transplanted in standard risk and those who had limited cGVHD had a significant better OS, (p = 0.05 and p = 0.05). Patients who had cGVHD and transplanted in standard risk had a better DFS, (p = 0.002 and p < 0.001). In summary, AHSCT in standard risk patients is associated with a better outcome than those transplanted in high risk and although not statistically significant, there is a higher incidence of aGVHD in Indian patients.

    The sole BMT centre in Malaysia caters only for children. Since 1987, 89 transplants have been performed using reverse barrier nursing techniques. The overall survival rate is 73% with the majority of survivors leading normal lives. The early and late infection rates of 46% and 13%, respectively, are comparable to those of other centres. Although the early septicaemia rate is 36% the immediate mortality rate is < 10%. GVHD is less frequent and severe and the interstitial pneumonitis rate lower than that in the West. The average cost of US $8000 per transplant is much lower than the cost of a transplant performed overseas. Thus we believe that our paediatric BMT programme is simple and cost-effective.
