OUTLINE: All patients undergo 1 session of cryoablation. Patients with high-grade sarcoma receive systemic chemotherapy 10-14 days after cryoablation at the discretion of the consulting medical oncologist, and undergo surgery 2-3 weeks following chemotherapy. Patients with low-grade sarcoma and those with high-grade sarcoma who do not receive chemotherapy undergo surgery 4-6 weeks after cryoablation. Surgery for all patients consists of en bloc resection or amputation, with limb salvage attempted when feasible. Patients are followed weekly for 3 weeks.
