Summary
Amputation does not improve survival for extremity soft tissue sarcomas (STS) compared to limb salvage surgery (LSS). However, amputation offers valuable local control and symptom management for select STS patients.
Area of Science:
- Oncology
- Surgical Oncology
- Orthopedic Oncology
Background:
- Soft tissue sarcomas (STS) of the extremity present treatment challenges.
- A common misconception suggests amputation improves survival and reduces recurrence in STS.
- Limb salvage surgery (LSS) is often preferred, but amputation remains an option.
Purpose of the Study:
- To compare survival outcomes between amputation and LSS for extremity STS.
- To investigate the impact of ablative surgery on local recurrence and overall survival.
- To clarify the role of amputation in STS management.
Main Methods:
- Retrospective cohort study of 278 patients with extremity STS.
- Comparison of 18 patients who underwent amputation versus 260 patients who underwent LSS.
- Analysis of prognostic factors including death, metastasis, and local recurrence.
Main Results:
- No statistically significant difference in survival between amputation and LSS groups (p > 0.05).
- Amputation was chosen for tumors involving neurovascular bundles, bone, or requiring extensive resection.
- LSS was performed in 94% of cases, with a median follow-up of 3.1 years.
Conclusions:
- Amputation does not increase overall survival for extremity STS compared to LSS.
- Amputation provides valuable local control and symptomatic relief for specific STS cases.
- Amputation remains a crucial surgical option for STS patients unsuitable for LSS.
