    Background and Aims: The present standard of care in treating lower extremity soft tissue sarcomas is function-sparing, limb-preserving resection and reconstruction with or without oncological therapy. The aim of this pilot study was to test the suitability and adequacy of the Finnish translations of two functional outcome questionnaires (Toronto Extremity Salvage Score and Musculoskeletal Tumor Society score) and to perform a preliminary investigation of functional outcomes of Finnish lower-limb soft tissue sarcoma patients after operative treatment. Materials and Methods: Between June 2015 and December 2015, consecutive surgically treated outpatients were asked to participate in the study. Demographic, clinical, surgical, and oncological outcome data were collected. Two functional outcome questionnaires were used (Toronto Extremity Salvage Score and Musculoskeletal Tumor Society scores). A comparative analysis is presented. Results: A total of 19 lower-limb soft tissue sarcoma patients with a mean follow-up time of 2 years and 10 months were included. All (n = 19) invited patients participated in the study. Mean age was 62.3 years. In total, 13 had high-grade sarcomas. Eight wounds were closed directly, four used skin grafts, and five required flap reconstructions. One patient required a tumor prosthesis, and one required a rotationplasty. A total of 14 patients received oncological therapy. No problems or difficulties were reported in using and completing the Finnish versions of the Toronto Extremity Salvage Score or Musculoskeletal Tumor Society questionnaires. The overall Toronto Extremity Salvage Score and Musculoskeletal Tumor Society scores were 88 and 76, respectively. Conclusion: This pilot study suggests that the Finnish versions of the Toronto Extremity Salvage Score and Musculoskeletal Tumor Society questionnaires are suitable for measuring functional outcome after lower extremity soft tissue sarcomas treatment. Functional outcomes vary from moderate to excellent.

    Objective: Radical excision of retroperitoneal or intra-abdominal soft tissue sarcomas may necessitate vessel resection and reconstruction. The aim of this study was to assess surgical results of retroperitoneal or intra-abdominal sarcomas involving major blood vessels. Methods: This was a retrospective single centre cohort study and a comprehensive review of literature. Patients with retroperitoneal or intra-abdominal sarcomas treated by the oncovascular team in Helsinki University Hospital from 2010 to 2018 were reviewed for vascular and oncological outcomes. A comprehensive literature review of vascular reconstructions in patients with retroperitoneal sarcoma was performed. Results: Vascular reconstruction was performed in 17 patients, 11 of whom required arterial reconstructions. Sixteen of the operations were sarcoma resections; the post-operative diagnosis for one patient was thrombosis instead of the presumed recurrent leiomyosarcoma. Early graft thrombosis occurred in two venous and one arterial reconstruction. Late thrombosis was detected in three (18%). The median follow up was 27 (range 0-82) months. Of the patients with sarcoma resections 5 (31%) died of sarcoma and further 4 (25%) developed local recurrence or new distant metastases. The comprehensive review of literature identified 37 articles with 110 patients, 89 of whom had inferior vena cava reconstruction only. Eight arterial reconstructions were described. Late graft thrombosis occurred in 14%. The follow up was 0-181 months, during which 57% remained disease free and 7% died of sarcoma. Conclusion: Vascular reconstructions enable radical resection of retroperitoneal and intra-abdominal sarcomas in patients with advanced disease. The complex operations are associated with an acceptable rate of serious perioperative complications and symptomatic thrombosis of the repaired vessel is rare. However, further studies are needed to assess the performance of the vascular reconstructions in the long term.
