Sarcoma metastatic to the brain: results of surgical treatment.
We report on 21 patients surgically treated for intraparenchymal brain metastasis from sarcoma, including six osteosarcomas, four leiomyosarcomas, three malignant fibrous histiocytomas, two alveolar soft-part sarcomas, two Ewing's bone sarcomas, one extraskeletal osteosarcoma, one extraskeletal Ewing's sarcoma, and two unclassified sarcomas. Median survival after craniotomy was 11.8 months. Patients with a preoperative Karnofsky performance score of > 70 survived for 15.7 versus 6.6 months for those with a Karnofsky performance score < or = 70. Patients. undergoing complete resection survived 14.0 versus 6.2 months for patients undergoing incomplete resection. Patients with evidence of lung metastases at the time of surgery survived 11.8 months, which was similar to the 10.5-month survival for patients with disease limited to the brain. The two patients with alveolar soft-part sarcoma are alive at 16 and 25 months after surgery. We conclude that surgery is effective in treating selected patients with sarcoma metastatic to the brain and that patients with metastasis from alveolar soft-part sarcoma may have a relatively good prognosis if they are surgically treated. The complete removal of all brain metastases and a Karnofsky performance score > 70 are associated with a favorable prognosis, whereas the presence of concurrent lung metastases is not a contraindication to surgery.
