Synopsis
Pulmonary metastases are a common manifestation of sarcoma that requires special attention. For decades, surgical resection of pulmonary metastases has been performed, and despite limited randomized data, surgery is increasingly accepted as an integral part in the management of metastatic disease. Although sarcoma is heterogeneous, common prognostic factors have been identified to guide surgeons prior to pulmonary metastasectomy including long disease-free interval, ability to obtain a complete resection, and extra-pulmonary disease control. Patients with adequate pulmonary reserve may undergo resection via thoracotomy or in select cases video-assisted thoracoscopic surgery (VATS). Long-term results indicate resection is potentially curative with significantly improved survival following complete resection. Recurrence, however, is not uncommon with many patients undergoing repeat resection. With advancing surgical technique and adjuvant therapies, patients with high or recurrent tumor burden are increasingly afforded disease control and potential cure. In this review, the prognostic characteristics of pulmonary metastases from sarcoma, pre-operative evaluation, operative technique, long-term outcomes, and management of complex patients are highlighted.
