Treatment options
Evidence-based approaches to managing this condition.
First-line treatments
Drug therapy and clinical monitoring
Active treatment with regular monitoring by a healthcare provider is recommended.
Wide local excision with limb preservation
Aggressive surgical resection with negative margins is the primary curative approach when tumor location permits limb-sparing surgery. Reconstruction may involve bone grafting or prosthetic devices.
Neoadjuvant chemotherapy
Preoperative chemotherapy (typically doxorubicin, cisplatin, methotrexate, or ifosfamide-based regimens) to shrink tumor size and facilitate surgical resection. Allows assessment of tumor response to agents.
Additional treatment options
Adjuvant chemotherapy
Postoperative chemotherapy to eliminate micrometastatic disease and reduce recurrence risk. Duration and agents depend on surgical margins and histologic response to neoadjuvant treatment.
medicationOncology surveillance program
Long-term follow-up with imaging to detect local recurrence and metastatic disease, particularly pulmonary metastases. Lifelong monitoring recommended given risk of late relapse.
monitoringRadiation therapy consideration
Adjuvant radiotherapy may be considered for positive surgical margins or locally advanced tumors where complete resection is challenging. Helps reduce local recurrence risk.
