Use of preoperative autologous blood donations and erythropoietin for treatment of giant cell tumor of the ischium.

Abstract

A 24-year-old man with an osteolytic lesion of the ischium was referred to the authors' institution. Computed tomography and magnetic resonance imaging studies showed that the lesion extended to and involved the subchondral bone of the acetabulum. Histologic examination of the biopsy specimen revealed giant cell tumor of bone. Following the biopsy, autologous blood was collected 4 times with recombinant human erythropoietin treatment definitive surgery was performed. Three weeks after the biopsy, the lesion was curetted and bone cementation was performed. The total blood loss during surgery was 3100 ml, which was replaced successfully with stored autologous blood without the need for homologous blood transfusion. The authors believe that without the erythropoietin treatment, autologous blood could have been collected only 3 times instead of 4 times, and the patient would have needed homologous blood.
