Summary
Achieving a wider surgical margin in soft tissue sarcoma surgery significantly improves local control and patient survival. A margin greater than 1 mm is associated with lower recurrence rates and better outcomes.
Area of Science:
- Oncology
- Surgical Oncology
- Sarcoma Research
Background:
- Soft tissue sarcoma treatment aims for local control and survival.
- Surgical margins are critical in preventing recurrence and metastasis.
Purpose of the Study:
- To evaluate the impact of surgical margin extent on survival, metastasis, and local recurrence in soft tissue sarcoma.
- To determine optimal surgical margin width for improved patient outcomes.
Main Methods:
- Retrospective analysis of 279 patients with non-metastatic soft tissue sarcoma.
- Assessment of surgical margin status (width and contamination) and correlation with clinical outcomes.
Main Results:
- Surgical margin extent did not significantly affect metastasis development.
- Contaminated or narrow (<1 mm) margins increased local recurrence rates.
- Wider margins (>1 mm) and non-contaminated margins correlated with lower recurrence and improved overall survival.
Conclusions:
- Increasing surgical resection width enhances local control and overall survival in soft tissue sarcoma.
- Non-contaminated margins, even if narrow, yield favorable survival rates.
- Radical resections in palliative settings were associated with poor outcomes.
