A Hematopoietic Stem Cell Transplantation Startup in Iraqi Kurdistan: Results in Thalassemia Patients and Analysis of the Methodology

In hemoglobinopathy-prone regions, like the Middle East, thalassemia is the most prevalent noncommunicable life-threatening disorder of children and is highly curable by hematopoietic stem cell transplantation (HSCT). Moreover, transplantation is very cost-effective, and HSCT programs can be established directly in middle-income countries (MICs) at a reduced cost while maintaining quality standards and outcomes consistent with international ones. The aim of the present study was to review and verify the efficacy of the applied methodology through the analysis of 47 consecutive matched-related HSCTs in children with thalassemia. In 2016, the first HSCT unit for adults and children with both malignant and nonmalignant diseases was developed in Iraqi Kurdistan, thanks to a capacity building project funded by the Italian Agency for Development Cooperation. Data on clinical activity were obtained from a cohort of patients treated in the newly established HSCT unit. Primary endpoints were overall survival (OS) and thalassemia-free survival (TFS). Startup of the HSCT unit was completed over a 3-year period. Assessing and meeting minimum requirements were crucial for the startup; moreover, a team of international health care professionals (HCPs), all experts in the field of HSCT, conducted the education and training phase, involving all the clinical and nonclinical professionals in the program. At a median follow-up of 2.6 years, the 3-year TFS and OS were 82.8% (SE, 5.5%) and 87.1% (SE, 4.9%), respectively. TFS and graft-versus-host-disease-free composite survival was 80.6% (SE, 5.8%). At present, the HSCT service is completely autonomous, and more than 250 transplants have been done in both adults and children. The minimal essential requirements for an HSCT startup may be affordable in many MICs. Our results for thalassemia are comparable with international data. A twinning program with an international group of experts and a capacity-building approach is crucial for the success of the program, a strategy that allows for rapid development of HSCT units.
