Total body irradiation (TBI) is the term used when radiotherapy is given to the whole body. Radiotherapy is a type of cancer treatment that uses high energy rays, similar to x-rays. TBI may be used in conjunction with high dose chemotherapy drugs. This is often used in preparation for a stem cell or bone marrow transplant.
This fact sheet from the Paediatric Integrated Cancer Service (PICS) provides information on total body irradiation. The resource gives an overview of:
- What is total body irradiation?
- Getting ready for total body irradiation
- What is it like?
- Taking care of your child during total body irradiation
- What should I bring?
- What are the side effects of total body irradiation?
Total body irradiation is an important part of the stem cell (bone marrow) transplant process. Before receiving the transplant, your child will be given chemotherapy and TBI therapy to prepare the body for new and healthy stem cells. TBI is given before the chemotherapy.
There may be further useful information about TBI from Cancer Institute NSW’s EviQ page which you can find here. You can also check out this resource from Cancer Research UK to learn more about TBI treatment. They also have this fact sheet which will provide details about the common types of side effects, including long term side effects.
