OBJECTIVE: To evaluate how functional disability impacts on health related quality of life (HRQOL) of patients with extremity soft tissue sarcoma (STS) at 1 year post-surgery. DESIGN AND SETTING: Survey of extremity STS patients pre-surgery and one-year post-treatment. PARTICIPANTS: 100 participants who were treated for extremity STS between 2001 and 2003 at four Canadian hospitals. Patients were over 16 years, non-metastatic at diagnosis, and had limb salvage surgery. OUTCOME MEASURES: Musculoskeletal Tumor Society Rating Scale (MSTS), a measure of impairment; Toronto Extremity Salvage Score (TESS), a measure of activity limitations; Reintegration to Normal Living Index (RNL), a measure of participation restrictions; and EQ-VAS, a measure of HRQOL. RESULTS: After adjusting for demographic and clinical variables, impairment explained 54%, activity limitations explained 48%, and participation restrictions explained 61% of the variation in HRQOL. After adjustment, when all three functional measures were included in the model, only participation restrictions had a significant impact on HRQOL explaining 63% of the variation. CONCLUSION: Impairment and activity limitations affect the daily activities a patient can perform, but it is the restriction in participation of life roles and situations that has the greatest effect on patient's HRQOL.
