Summary
Planned preservation surgery for soft tissue sarcomas adjacent to critical structures, like bone and major nerves, allows for negative surgical margins and avoids radiotherapy. This oncologic procedure shows no significant adverse effect on survival or local recurrence rates.
Area of Science:
- Orthopedic Surgery
- Surgical Oncology
- Musculoskeletal Oncology
Background:
- The management of soft tissue sarcomas adjacent to critical structures remains controversial.
- Planned preservation surgery involves meticulous detachment of periosteum or neurovascular sheath based on imaging and intraoperative findings.
Purpose of the Study:
- To investigate the clinical outcomes of soft tissue sarcomas adjacent to critical structures.
- To validate the efficacy of planned preservation surgery for these tumors.
Main Methods:
- Retrospective analysis of 57 soft tissue sarcoma cases adjacent to critical structures (2004-2010).
- Comparison of oncological outcomes and histological surgical margins between preserved and resected critical structures.
- Evaluation of overall survival and local recurrence-free survival rates.
Main Results:
- Five-year overall survival and local recurrence-free survival rates were 75.9% and 83.2%, respectively.
- Histologically negative surgical margins were achieved in 81% of preserved cases.
- Postoperative radiotherapy was avoided in 53% of preserved cases, with no significant difference in survival or recurrence rates compared to resected cases.
Conclusions:
- Planned preservation surgery can achieve histologically negative margins in most soft tissue sarcomas adjacent to bone or major vessels.
- This approach allows for avoidance of postoperative radiotherapy without compromising oncological outcomes.
- The procedure is validated as safe and effective, with no significant adverse impact on survival or local recurrence rates.
