Summary
Adequate surgical margins are crucial for controlling soft tissue sarcomas of the extremities. Limb-sparing surgery (LSS) is increasingly used, but local recurrence risk factors include age, tumor grade, and recurrence at presentation.
Area of Science:
- Orthopedics
- Surgical Oncology
- Medical Oncology
Background:
- Adjuvant treatments for extremity soft tissue sarcomas have evolved.
- Management changes impact local recurrence rates.
- Understanding factors influencing local failure is critical.
Purpose of the Study:
- To assess the impact of evolving management strategies on local recurrence rates in extremity soft tissue sarcomas.
- To identify factors predicting local failure in these tumors.
- To evaluate the effectiveness of limb-sparing surgery (LSS) and adjuvant therapies.
Main Methods:
- Retrospective review of 315 adult patients with operable, nonmetastatic soft tissue sarcoma of the lower extremity.
- Analysis of treatment approaches, including limb-sparing surgery (LSS) versus amputation.
- Multivariate analysis to identify independent predictors of local failure.
Main Results:
- Local recurrence was directly correlated with inadequate surgical margins.
- Adjuvant radiotherapy and chemotherapy showed no significant decrease in local recurrence post-LSS.
- Independent predictors of local failure included older age, prior recurrence, high grade, inadequate margins, and specific histologic types (embryonal rhabdomyosarcoma, neurofibrosarcoma).
Conclusions:
- Resection with adequate surgical margins is paramount for local control of extremity sarcomas.
- The role of adjuvant treatments following LSS requires further evaluation.
- A comprehensive risk factor profile is essential for tailoring treatment plans for lower extremity sarcomas.
