Hematopoietic cell transplant, also known as stem cell transplant, is a procedure in which healthy blood-forming cells are infused into a patient to replace damaged or diseased cells. These transplanted cells can come from the patient themselves (autologous transplant) or from a donor (allogeneic transplant). Hematopoietic cell transplants are used to treat various blood disorders, such as leukemia, lymphoma, and multiple myeloma, as well as certain non-malignant conditions like aplastic anemia and sickle cell disease. The goal of the transplant is to restore the patient's ability to produce healthy blood cells and immune cells. The procedure involves high-dose chemotherapy or radiation to destroy the diseased cells before the transplant is performed. Hematopoietic cell transplant is a complex and potentially life-saving treatment option that requires careful consideration and management by a specialized medical team.
