Osteosarcoma and MFH of Bone With Metastatic Disease at Diagnosis
Multifocal osteosarcoma is different from osteosarcoma which presents with a clearly delineated primary lesion and limited bone metastasis. Multifocal osteosarcoma classically presents with symmetrical, metaphyseal lesions, and it may be difficult to determine the primary lesion. Patients with multifocal bone disease at presentation have an extremely poor prognosis. No patient with synchronous multifocal osteosarcoma has ever been reported to be cured, but systemic chemotherapy and aggressive surgical resection may achieve significant prolongation of life.[10,11]
When the usual treatment course of preoperative chemotherapy followed by surgical ablation of the primary tumor and resection of all overt metastatic disease (usually lungs) followed by postoperative combination chemotherapy cannot be used, an alternative treatment approach may be used. This alternative treatment approach begins with surgery for the primary tumor, followed by chemotherapy, and then surgical resection of metastatic disease (usually lungs). This alternative approach may be appropriate in patients with intractable pain, pathologic fracture, or uncontrolled infection of the tumor when initiation of chemotherapy could create risk of sepsis.
Current Clinical Trials
Check for U.S. clinical trials from NCI's list of cancer clinical trials that are now accepting patients with metastatic osteosarcoma and metastatic childhood malignant fibrous histiocytoma of bone. The list of clinical trials can be further narrowed by location, drug, intervention, and other criteria.
General information about clinical trials is also available from the NCI Web site.
