Popliteal sarcomas: presentation, prognosis, and limb salvage

Area of Science:

• Orthopedic Surgery
• Surgical Oncology
• Musculoskeletal Oncology

Background:

• Soft tissue sarcomas in the popliteal fossa are rare and challenging to resect due to their location.
• These tumors have a poorer prognosis compared to those within the extremity compartments.
• Extracompartmental location necessitates careful surgical planning to preserve neurovascular structures.

Purpose of the Study:

• To evaluate the initial presentation, local recurrence, distant metastasis, and morbidity of limb salvage procedures for popliteal fossa soft tissue sarcomas.
• To assess the outcomes of surgical resection and adjuvant therapies in this patient cohort.
• To determine the limb salvage rate and associated complications.

Main Methods:

• Retrospective analysis of 29 consecutive patients operated on between 1989 and 2003.
• Data collection included tumor grade, presentation, surgical margins, adjuvant treatments (radiotherapy and chemotherapy), and follow-up.
• Assessment of local recurrence, distant metastasis, limb salvage rates, and postoperative complications.

Main Results:

• The median follow-up was 79 months. High-grade tumors were smaller than low- and intermediate-grade tumors.
• Local recurrence rate was 10.3%. Four high-grade tumors metastasized distantly.
• The limb-salvage rate was 86.2%, with low morbidity including wound dehiscence (6 patients) and mild flexion contractures (4 patients).

Conclusions:

• Popliteal fossa soft tissue sarcomas often present atypically.
• Limb salvage is achievable in the majority of patients, providing good local and systemic control.
• Surgical resection combined with adjuvant therapies can lead to favorable outcomes with acceptable morbidity.
