- Discussion:
- fibrosarcoma of bone occurs most often in adolescents or young adults;
- presents in major long bones, presenting as painful mass;
-
preoperative staging studies are needed
to differentiate low grade
stage I fibrosarcomas from high grade
stage II lesions;
- X-rays
- poorly defined, destructive, radiolucent lesion of metaphysis;
-
stage I tumors:
- remain w/ in bone and have a distinct, well defined margin;
-
high grade tumors:
- poorly marginated & permeative lesion w/ bone destruction;
- Treatment:
- limb salvaging excision w/ wide margin sufficies for
stage Ia tumors,
whereas
stage IIb fibrosarcomas require radical or wide margins w/
adjuvant chemotherapy or radiation therapy;
- prognosis for patients with
stage II fibrosarcoma is guarded;
