BACKGROUND: In musculoskeletal sarcomas, brain metastases are rare, but
severely affect quality of life. METHODS: All patients with musculoskeletal
sarcomas who were treated at our institutions from 1975 to 1997 were
reviewed for examples of brain metastasis. RESULTS: Of 480 sarcoma
patients, 179 had distant metastases, including 20 patients with brain
metastases (4.2%). Alveolar soft part sarcoma (3/4), extraskeletal Ewing's
sarcoma (2/8), rhabdomyosarcoma (2/13) and bone Ewing's sarcoma (2/18)
tended to metastasize to the brain. All 20 patients had distant or local
relapses and 16 of the 20 patients had pulmonary metastases. Three patients
underwent surgical treatment and two of them survived over 1 year. Mean
survival after diagnosis of brain metastasis was 5.1 months. CONCLUSIONS:
Patients with alveolar soft part sarcoma, Ewing's sarcoma, rhabdomyosarcoma
and pulmonary metastases have a high risk of brain metastasis.
