Current Use and Trends in Hematopoietic Cell Transplantation in the United States.

Hematopoietic Cell Transplantation (HCT) is an established curative treatment for a number of malignant and nonmalignant diseases involving the hematopoietic system and some solid tumors. In this report, we provide information about the number of HCT procedures performed in the United States in 2015, and analyze trends and outcomes of HCT as reported to the Center for International Blood and Marrow Transplant Research (CIBMTR). We show that the number of HCTs performed annually continues to increase, as the indications for HCT, preferred donor sources, and graft-versus-host prophylaxis continue to evolve. We report on general overall survival by indication, by disease status at transplantation, and by transplant type. This report provides a current perspective on transplantation activity in the United States with a focus on recent trends in alternative donors and contemporary transplantation practices.
