PURPOSE: The main purpose of the present study was to evaluate if there is a difference between objective or subjective administration of the MSTS score in a cohort of patients affected by musculoskeletal oncological diseases. MATERIALS AND METHODS: All patients who underwent surgery for bone or soft tissue localization of neoplastic disease in lower or upper limb from June 2015 to June 2020 were considered eligible. In order to administer the score as a PROM, the MSTS was first translated and cross-culturally adapted in Italian. During follow up visits, all patients filled out Italian versions of SF36, TESS and MSTS. Psychometric properties of the Italian version of MSTS were analyzed. Correlation between objective and self-administered MSTS score was assessed through Pearson's coefficient. RESULTS: A finale sample of 110 patients were included: 59 affected by lower extremity involvement and 51 affected by upper extremity involvement. The Italian version of the MSTS score showed good psychometric properties for both lower and upper extremity. The correlation between self-administered and hetero-administered version of the questionnaire was as high as r = 0.97 for lower extremities and r = 0.96 for upper extremities. CONCLUSIONS: The Italian version of the MSTS is a valid tool to evaluate outcomes of surgical treatment of patients affected by extremities tumors and it can be used as a subjective tool for both lower and upper extremity.
