title: Blood and marrow transplantation in the People's Republic of China.
abstract: Syngeneic BMT was first performed successfully in China in 1964. In 1981, allogeneic BMT was applied in an acute leukemia patient with success. Since then, the number of BMTs has been increasing gradually, especially since the 1990s. More than 2000 stem cell transplants per year have been performed in recent years in more than 50 BMT units in mainland China. A survey of 16 BMT units from 1986 to 2005 indicates that the predominant types of transplantation performed are identical sibling (36%), related mismatched/haploidentical (11.2%), unrelated (7.5%) and autologous (44.5%) and that the distribution of disease entities and prevalent diseases being transplanted are AML (31%), ALL (16.1%), CML (19.1%) and lymphoid malignancy (22.2%). The number of transplants from unrelated donor or related mismatched/haploidentical donor has increased significantly in the past 5 years. BM and G-CSF-mobilized peripheral blood are used about equally often as a source of hematopoietic stem cells, or they are used in combination. Umbilical cord blood is used least often. Leukemias for allogeneic and lymphoid malignancies for autologous BMT continue to increase, but the increase in BMT for CML has been slow since 2004. By the end of 2007, HLA data were available on more than 700,000 individuals in the Chinese Marrow Donor Program, and 800 stem cell donations have been carried out from these. Related HLA-mismatched/haploidentical BMT has achieved comparable outcomes in terms of severe acute GVHD, chronic GVHD, relapse, treatment-related mortality, disease-free survival (DFS) and overall survival (OS) with HLA-identical sibling transplantation in the author's two BMT units. Cord blood co-infusion as the third-party cells could significantly reduce the incidence and severity of acute GVHD, steroid-refractory acute GVHD and extensive chronic GVHD without an increase in leukemia relapse and could improve DFS and OS.
