Summary
Limb salvage surgery for osteosarcoma offers comparable survival and local control to amputation when wide or radical resection is achieved. This approach is effective for young patients, impacting tumor control and survival outcomes.
Area of Science:
- Orthopedic Oncology
- Surgical Oncology
- Pediatric Oncology
Background:
- Limb salvage surgery for osteosarcoma is debated due to potential higher local recurrence rates.
- Chemotherapy is a standard adjuvant treatment for osteosarcoma.
Purpose of the Study:
- To compare ablative surgery versus limb salvage surgery for osteosarcoma.
- To identify independent prognostic factors for survival in osteosarcoma patients.
Main Methods:
- Retrospective review of 130 patients under 21 with extremity osteosarcoma.
- Analysis of surgical margins (Enneking classification), local recurrence, and survival rates.
- Multivariate analysis to determine independent prognostic factors.
Main Results:
- 5-year disease-free survival: 60% for amputation vs. 71% for limb salvage.
- Local recurrence rates: 4.3% for ablation vs. 1.2% for limb salvage.
- Independent prognostic factors for survival included tumor volume, chemotherapy response, and initial metastases.
Conclusions:
- Limb salvage surgery provides comparable local and systemic tumor control to amputation in osteosarcoma when wide or radical resection is feasible.
- Surgical approach (ablation vs. limb salvage) did not impact outcomes if adequate margins were achieved.
- Tumor volume, chemotherapy response, and metastatic status are critical prognostic indicators for osteosarcoma survival.
