Abstract

Regarding all the above mentioned studies [49,50,51,52,53],
only 14 cases of malignant bone and soft tissue tumors of the
upper extremity have been treated by en bloc resection,
intraoperative extracorporeal irradiation, and reimplantation.
Two of these cases were soft tissue tumors in the forearm and
hand. Six cases were upper-extremity bone tumors. Six
malignant bone tumors in the forearm and hand have been
treated with this method, including 4 tumors in the radius, 1
tumor in the ulna, and 1 tumor in the metacarpal. There were
two osteosarcomas, one malignant fibrous histiocytoma, and
one intraosseous liposarcoma; two were unknown. One of 2
patients with tumor of the radius reported by Uyttendaele et al.
[52] had normal mobility and elbow and wrist function at final
follow-up examination, but the other patient developed
osteomyelitis, followed by wrist arthrodesis. A patient with
parosteal osteosarcoma in the ring finger metacarpal described
by Revell et al. [53] had excellent finger movement 3 months
after surgery: she was able to play the piano.
A single dose between 50 and 200 Gy can completely sterilize
tumor cells. Takahashi et al. [54] reported that animal studies of
extracorporeal autograft irradiation at this low dose range
showed excellent incorporation of bone grafts. Yamamoto et al.
