[Amputation or limb salvage? Assessing quality of life after tumor operations of the lower extremity].

The purpose of this study was to compare quality of life and subjective well-being between patients who underwent either amputation or limb-salvage procedures for lower extremity sarcomas in order to determine if this aspect can be considered in the decision on the type of surgery. Sixty-six patients were evaluated at least 1 year after surgery and systemic therapy for lower extremity sarcomas. Self-report questionnaires such as the Quality of Life Questionnaire (QLQ-C30), the Life Satisfaction Questionnaire (FLZ), and the Enneking Score (MSTS) were used. There were no differences in quality of life and subjective well-being between the two groups. Scores of the symptom scale (14.1 vs 13.2), the global quality of life (70.9 vs 71.0) as well as scores of the function scale (51.7 vs 50.3) were similar. Small differences in scores were found in social functioning but not in scores of physical, cognitive, and emotional functioning. Global subjective well-being in both groups was also similar (219.5 vs 223.7). High satisfaction was found in marital life and partnership as well as in self-assessment. The least satisfaction was found in finances. Results in functional outcome after limb-salvage procedures (77% vs 65%) were better. Although more complications were reported after limb-salvage procedures, they did not seem to have any impact on quality of life ( p=0.235, r(p)=0.112) and subjective well-being ( p=0.856, r(p)=0.140) of the patients whereas a correlation to function could be shown ( p<0.001, r(p)=0.595; p=0.015, r(p)=0.304). Additionally, a correlation between subjective well-being and the location of either amputation or reconstruction ( p=0.039, r(p)=- 0.309) could be shown. These findings demonstrate that the type of surgery has no influence on quality of life and subjective well-being after lower extremity sarcomas. Thus the decision for either limb-salvage procedures or amputation cannot be based on quality of life and subjective well-being but must be determined by oncological criteria.
