Malignant tumors of the extremities are uncommon. Their surgical treatment, whether conservative or not, may cause sequelae. Functional assessment of patients is essential for research purposes, but also follow-ups and adaptation of treatments. The Musculoskeletal Tumor Society Rating Scale (MSTS) is a disease-specific functional scoring system often used in English literature. Currently, no studies have been published on a valid French translation of the MSTS, whether for the lower or upper extremities. We, therefore, conducted a prospective study to answer the following questions: (1) Are the proposed adapted French versions of the MSTS valid? (2) Do the psychometric properties of the two versions obtained make their use relevant?
The translation and cross-cultural adaptation were carried out following the recommendations of Beaton and Guillemin to obtain two versions: one for patients who had undergone upper extremity surgery (MSTS-UE) and one for those who had undergone lower extremity surgery (MSTS-LE). A prospective multicenter cohort study was then carried out to analyze the psychometric properties of these two versions.
A total of 250 patients from 3 referral centers were enrolled in this study. A confirmatory factor analysis (CFA) demonstrated that the two French versions of the MSTS (MSTS-LE and MSTS-UE) were a good fit with a root mean square error of approximation (RMSEA)<0.08 and a comparative fit index (CFI)>0.90. The psychometric properties of the two versions were validated with internal consistency (Cronbach alpha>0.7), convergent validity of each item with its score (> 0.4), and sufficient criterion validity (Pearson correlation coefficient>0.4). The discriminant validity analysis showed that there was a significant correlation between each version and the performance status (PS) (p<0.05).
This study produced a French version of the MSTS scoring system and validated the psychometric properties of the two versions obtained (MSTS-UE and MSTS-LE). Therefore, the French MSTS scoring system is a valid measurement that can be used in international studies.

四肢的恶性肿瘤并不常见。无论采用保守治疗还是手术治疗，都可能导致后遗症。为了研究目的，以及进行随访和调整治疗，对患者进行功能评估至关重要。肌肉骨骼肿瘤学会评分系统（MSTS）是一种常用于英文文献的疾病特异性功能评分系统。目前，尚未发表关于 MSTS 下、上肢的有效法语翻译的研究。因此，我们进行了一项前瞻性研究，以回答以下问题：（1）提出的 MSTS 法语改编版是否有效？（2）获得的两个版本的心理测量特性是否使其具有相关性？
翻译和跨文化适应是按照 Beaton 和 Guillemin 的建议进行的，以获得两种版本：一种用于上肢手术患者（MSTS-UE），另一种用于下肢手术患者（MSTS-LE）。然后进行了一项前瞻性多中心队列研究，以分析这两种版本的心理测量特性。
这项研究共纳入了来自 3 个转诊中心的 250 名患者。验证性因子分析（CFA）表明，MSTS 的两种法语版本（MSTS-LE 和 MSTS-UE）具有良好的拟合度，近似均方根误差（RMSEA）<0.08，比较拟合指数（CFI）>0.90。通过内部一致性（Cronbach alpha>0.7）、每个项目与其得分的收敛有效性（>0.4）和足够的标准有效性（Pearson 相关系数>0.4）验证了两个版本的心理测量特性。判别有效性分析表明，每个版本与表现状态（PS）之间存在显著相关性（p<0.05）。
本研究产生了 MSTS 评分系统的法语版本，并验证了获得的两个版本（MSTS-UE 和 MSTS-LE）的心理测量特性。因此，法语 MSTS 评分系统是一种有效的测量方法，可用于国际研究。
