Surgical Outcomes for Liposarcoma of the Lower Limbs With Synchronous Pulmonary Metastases

Background and Objectives: Surgical resection of pulmonary metastases from soft tissues sarcomas has typically yielded disparate results, owing to the histologic heterogeneity of various series and the presentation times relative to primary tumor discovery. It was our hypothesis that with expeditious, curative surgical resection of both, primary and metastatic disease, patients with liposarcoma of the lower limb and synchronous, resectable, pulmonary metastases might achieve satisfactory outcomes. Methods: A consecutive sample clinical study, with a mean follow-up duration of 30 months. Twenty-two patients (mean age, 50 years), each presenting with a liposarcoma of the lower limb and synchronous, resectable, pulmonary metastases, underwent curative resection of both the primary mass and all pulmonary metastases within a mean of 18 days from presentation (range 9-32 days). Results: Mean overall survival was 28 months, disease-related survival (SE) was 9% at 5 years (+/- 9.7%), and disease-free survival was 9% at 5 years (+/- 7.6%). Conclusion: Expeditious, curative resection of both primary and metastatic lesions yields acceptable near-term results, with potential for long-term survival, in patients with liposarcoma of the lower limb and synchronous pulmonary metastases.
