OBJECTIVES:  Treatment of soft tissue sarcomas (STS) of the upper extremity can have an impact on extremity function. The authors conducted a systematic literature review to identify which structured outcome measures have been used to evaluate the upper extremity function after treatment of STS. METHODS:  The authors searched the PubMed database to identify relevant articles using predefined search terms. Two independent reviewers assessed article eligibility. Articles written in English using a defined system to assess upper extremity function after treatment of STS were included. The reference lists of eligible articles were reviewed to identify relevant articles. RESULTS:  The search yielded a total of 1448 studies of which 83 articles met the inclusion criteria. Three most commonly used outcome measures were the Musculoskeletal Tumour Society Score (MSTS) -93 (n = 56), Toronto Extremity Salvage Score (TESS) (n = 19) and MSTS -87 (n =
