[Late effects of ionizing radiations on the bone marrow].

Bone marrow is a tissue with a high mitotic activity, and consequently exquisitely radiosensitive. The clinical effects of bone marrow irradiation and its ability of regeneration are related to the volume irradiated. Management of hematopoietic side effects of radiation include surveillance, antibiotics, blood products transfusion, and more scarcely hematopoietic growth factors, bone marrow transplantation and peripheral blood stem cells reinfusion.
