Myeloablative Total Body Irradiation (TBI)

Overview

Myeloablative Total Body Irradiation (TBI) is a specialized radiation therapy used as part of the conditioning regimen for allogeneic hematopoietic stem cell transplantation (HSCT) in patients with leukemia and other blood cancers and disorders. TBI delivers radiation to the entire body, targeting both cancerous cells and the bone marrow, to prepare the body for the transplant. The therapy is carefully planned to ensure accurate dosing and safe delivery. Depending on the patient's age, disease, and transplant type, various dose and fractionation schedules are used.

Since TBI involves irradiating the entire body, precautions are taken to protect critical organs and limit side effects. Myeloablative TBI is typically administered over several days to reduce toxicity and allow for precise treatment.
