Brief summary
The only curative therapy for thalassemia major remains the replacement of the defective erythropoiesis by allogeneic hematopoietic stem cell transplantation(allo-HSCT). We conduct a prospective multicenter study to evaluate the efficacy of allo-HSCT in the treatment of thalassemia major.
Detailed description
Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is one of the established curative option for thalassemia major (TM). Previous study has predicted that more than 90% of TM patients can survive after allo-HSCT with a thalassemia-free survival (TFS) in around 80% of them.The purpose of this study is to evaluate the efficacy of allo-HSCT in the treatment of thalassemia major.
