Major Amputations for Extremity Soft-Tissue Sarcoma.
MetadataShow full item record
<h4>Introduction</h4>With modern techniques facilitating limb conservation, amputation for extremity soft-tissue sarcoma (ESTS) is now rare. We sought to determine the indications and outcomes following major amputation for ESTS and whether amputation is prognostic of oncological outcomes in primary disease.<h4>Patients and methods</h4>Patients undergoing major amputations for ESTS from 2004 to 2014 were identified from electronic patient records.<h4>Results</h4>The amputation rate in primary localized disease was 4.1%. Overall, 69 patients were identified, including 23 (33.3%) amputations for primary localized disease, 36 (52.2%) amputations for recurrent disease, and 10 (14.5%) amputations for metastatic disease. The local recurrence rate for localized disease at 3 years was 10.4%. Three-year overall survival (OS) was 50.3% following curative amputation, with a median survival of 41 months, and median OS following palliative amputation was 6 months. In the context of primary, localized disease, patients undergoing amputation had a greater proportion of high-grade tumors (69.6% vs. 41.1%; p = 0.009) of greater size (median 16.0 vs. 9.0 cm; p = 0.003) when compared with patients undergoing limb-conserving surgery. The rates of systemic relapse and disease-specific survival were poorer following amputation compared with limb-conserving surgery, however mode of surgery (amputation vs. limb conservation) was only prognostic for OS.<h4>Conclusions</h4>Amputation maintains an important role in ESTS and achieves durable local control in those unsuitable for limb-conserving surgery. Survival following amputation in the presence of metastatic disease is poor and should be reserved for patients with significant symptoms.
