Özet
Objective: This study aimed to translate and cross-culturally adapt the musculoskeletal tumor society (MSTS) scoring systeminto Turkish and to determine the reliability and validity of the translated version for the functional evaluation of patients withmusculoskeletal tumors.Methods: A total of 36 patients (16 women, 20 men; mean age=36.6; age range=13–75 years) who underwent limb-salvage surgeryowing to benign aggressive or malignant musculoskeletal tumors were included in the study. Translation and back translations of theMSTS were performed according to the published guidelines. Short form (SF) 36 physical component, Western Ontario and McMaster Universities Arthritis Index (WOMAC), disabilities of the arm, shoulder, and hand (DASH), and range of motion scale (ROMS)that were previously analyzed for Turkish validation were used for validity. Reliability of MSTS Turkish version was evaluated bycalculating test-retest reliability and internal consistency. Intraclass correlation coefficient (ICC) was used to evaluate the inter-observer consistency and test-retest reliability. Alpha coefficient (Cronbach’s alpha) was used to evaluate the internal consistency.Results: It was observed that total MSTS score has a strong negative correlation with DASH (r=−0.689; p<0.001) and WOMACscores (r=−0.634; p<0.001) and moderate correlation with the ROMS score (r=0.521; p<0.001). Total MSTS score also had a statistically significant strong correlation with SF-36 scores (r values ranging from 0.425 to 0.609, p<0.001). Inter and intra-observerreliability of the MSTS scale was found to be excellent (Cronbach’s α=0.97 p<0.001; ICC: 0.97 (0.96–0.99; p<0.001). Unlike othersubscales, statistical correlation between dexterity and hand-positioning subscales of MSTS with DASH scores was found to beinsignificant (r=−0.533, p =0.061 and r=−0.336, p=0.261, respectively).Conclusion: The Turkish version of the MSTS scoring system seems to be a valid and reliable scale that measures the correct anddesired values in the evaluation of health-related quality of life in orthopedic oncology. Reliability coefficients of the Turkishversion of MSTS were determined to be strong.Level of Evidence: Level II, Diagnostic Study
