A Comparison of Limb Salvage Versus Amputation for Nonmetastatic Sarcomas Using Patient-reported Outcomes Measurement Information System Outcomes

Introduction: The Patient-reported Outcomes Measurement Information System (PROMIS) is a scoring tool that allows comparisons between patients with rare conditions and more common ailments, or the general US population. PROMIS outcomes were compared between the limb salvage and amputee patients for nonmetastatic sarcomas to the US population. Methods: One hundred thirty-eight patients were included in the analysis. Patients were divided into the limb salvage and amputee cohorts, as well as based on the follow-up (1 to 11 or 12+ months). Results: Seven PROMIS domains were evaluated, and higher scores were found in both the limb salvage group and patients >12 months from surgery. The limb salvage group also had improved emotional health compared with the US population. Discussion: Improvements in PROMIS values are observed in limb salvage patients and in patients >12 months from surgery. Limb salvage patients demonstrate improved emotional health compared with the US population.
