Abstract

Background/Objectives: Oligometastatic sarcoma pulmonary metastases (PM) are typically treated with resection and/or chemotherapy. We hypothesize that stereotactic body radiotherapy (SBRT) can be an alternative to surgery that can achieve high rates of local control (LC) with limited toxicity. Methods: Thirty consecutive sarcoma patients received SBRT to 39 PM's from 2011 to 2015 at two university hospitals to a median dose of 50 Gy in 4–5 fractions with CyberKnife or linear accelerator. Patients underwent CT or PET/CT scans q3 months after SBRT. Results: 77% received prior chemotherapy, 70% had 1–3 prior pulmonary resections, and 26% received prior thoracic radiotherapy. Median lesion size was 2.4 cm (range 0.5–8.1 cm). Median follow-up was 16 and 23 months for patients alive at last follow-up. At 12 and 24 months, LC was 94% and 86%, and OS was 76% and 43%. LC and OS did not differ by SBRT technique, fractionation regimen, lesion location, histology, or size (all P > 0.05). Three developed grade 2 chest-wall toxicity with no other grade ≥2 toxicities. Conclusions: This is the largest series on SBRT for sarcoma PM's and demonstrates that SBRT is well-tolerated with excellent LC across tumor locations and sizes. SBRT should be considered in these patients, and prospective studies are warranted. J. Surg. Oncol. 2016;114:65–69.
