Hematopoietic stem cell transplantation in Oman.

Hematopoietic SCT (HSCT) is an integral part of the management of patients with hematologic disorders. The Sultanate of Oman, with a population of 2.3 million, has an HSCT program based in the Sultan Qaboos University (SQU) hospital. Initiated in 1995, this two-bed unit continues to be the only program in the country. Between June 1995 and August 2006, a total of 128 patients underwent HSCT in this center, averaging about 10-12 transplants per year. The median age of these patients was 11 years (2 months to 45 years). Hematologic malignancies (49%) and inherited disorders (42%) constituted the major transplant indications, whereas BM failure accounted for the remaining. The majority of transplants carried out so far have been HLA-matched sibling-donor allogeneic HSCTs. Among the inherited disorders, homozygous beta-thalassemia and primary immunodeficiency are important transplant indications in this center. The approximate cost of an uncomplicated transplant in this center is US$50,000. The success of this program has now led to the initiation of a new and larger HSCT complex to provide the opportunity for more patients to benefit from this treatment modality within the country.
