Function and quality of life among primary osteosarcoma survivors in Iran: amputation versus limb salvage

Abstract

Purpose: This study aimed to evaluate the psychometric properties of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) in Iranian osteosarcoma patients and apply this to compare the functional level, quality of life, symptoms and financial burden of the patients who underwent amputation and limb-salvage operations.

Methods: This study was conducted at the main referral orthopedic centers in the southwest of Iran from 2006 to 2016. After complete review of medical records, 48 patients were invited to attend the outpatient clinic and participate in the study via initial telephone interview. All data were entered in the Statistical Package for the Social Sciences version 15.0, and p values <0.05 were considered statistically significant.

Results: In total, 48 patients with extremities osteosarcoma completed the study. Of these, 31 had been treated with limb-salvage operation and 17 had undergone amputation. In functioning subscale, all the mean score of items, except social function, were higher in the limb salvage group than the amputee group. The mean scores (SD) of global health and quality of life were 64.5(13.2) and 61.2± 12.4 in the limb salvage and amputee groups, respectively. In the financial impact subscale, the mean score (SD) in the limb salvage group was 68.8± (29.7) compared to 74.5(25.0) in the amputee group.

Conclusion: Results support the responsiveness of the EORTC QLQ-C30 for Iranian osteosarcoma patients. Applying this questionnaire revealed similar functional outcome, quality of life, symptoms and financial burden between amputation and limb-salvage groups.
