The Center for International Blood and Marrow Transplant Research (CIBMTR ) keeps a research database. It uses this database to collect and study the medical data for patients that have received Hematopoietic Cell Transplantation, Other Cellular Therapies and Marrow Toxic Injuries. It also collects and studies data from donors who give bone marrow or peripheral blood stem cells (PBSCs). These therapies are used to treat cancer and other diseases. The purpose of this study is to add more data to the database. Participants will have medical data (data about their disease, transplant or cellular therapy) collected before and after transplant cellular therapy, and once a year afterwards for life.

The primary purpose of the Research Sample Repository is to make blood samples available for research studies related to histocompatibility and hematopoietic cell transplantation (HCT) or other cellular therapy.

The CF Patient Registry is an observational study. It does not involve medical treatments and serves only as an epidemiologic record of demographics, characteristics of disease and treatment, utilization patterns, and clinical outcomes.
