Functional Outcome After Lower Extremity Soft Tissue Sarcoma Treatment: A Pilot Study Based on Translated and Culturally Adapted Measures.

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.

Treatment of compound tibia fracture with microvascular latissimus dorsi flap and the Ilizarov technique: A cross-sectional study of long-term outcomes.

BACKGROUND: Extensive compound tibial fractures present reconstructive challenges. The present study aimed to assess the outcomes of microvascular latissimus dorsi (LD) flap combined with the Ilizarov technique for extensive compound tibial fractures with bone loss and bone healing complications. METHODS: Patient records were reviewed retrospectively. The Lower Extremity Functional Scale (LEFS), the Disabilities of the Arm, Hand and Shoulder (DASH), and the 15D health-related quality of life (HRQoL) instrument were applied. RESULTS: Between 1989 and 2014, 16 patients underwent reconstruction with a microvascular LD flap and bone transport (11/16) or late bone lengthening (5/16). The mean clinical follow-up time was 6.6 (standard deviation (SD): 6.5) years. Three patients had minor complications requiring reoperation. Partial necrosis of one flap required late flap reconstruction in one case. Late bone grafting was used to enhance union in eight of 16 cases. The mean new bone gain was 3.8 cm (SD: 2.5). Overall, 11 patients completed the questionnaires in a mean of 22.3 years (SD: 2.4) after surgery. The main findings revealed a relatively good function of the reconstructed limb and good shoulder function. The mean HRQoL was comparable to that of an age-standardized sample of the general population. CONCLUSION: Segmental tibia transport and lengthening to correct limb length discrepancy do not compromise the microvascular muscle flap. Combined microvascular LD flap reconstruction and the Ilizarov technique can be used in treating acute compound tibial defects, pseudoarthrosis, and osteitis, all associated with significant amputation risk. Fair long-term functional outcomes and HRQoL are achieved when these combined techniques are used.

Microvascular reconstructions after extensive soft tissue sarcoma resections in the upper limb.

AIMS: Limb-sparing surgery combined with radiotherapy (RT) is the basis of extremity soft tissue sarcoma (STS) treatment. The aim of this study was to evaluate the results of microvascular reconstruction after extensive tumour resections in the upper extremity. METHODS: Twenty patients with STS of the upper extremity were treated with excision and microvascular reconstruction. RT was administered if surgical margins were less than 25 mm. Results were evaluated retrospectively. RESULTS: Twenty free flaps were performed and no flaps were lost. There was no operative mortality, and wound complication rate was 15%. Median follow-up length was 74 months. Five-year local recurrence-free survival was 57%, metastasis-free survival 67%, disease-free survival 45% and disease-specific overall survival 80%. Ten patients had no or only mild impairment of upper extremity function, seven had impaired function affecting daily life, and three patients underwent amputation. For patients treated with curative intent, limb salvage rate was 94%. CONCLUSIONS: Free flaps are useful and reliable in the treatment of patients with STS of the upper extremity. Without microvascular reconstruction limb salvage would have been impossible in these patients. Oncological outcome is comparable to other extremity STS patients and upper extremity function is acceptable.

Microvascular reconstruction after resection of soft tissue sarcoma of the leg.

BACKGROUND: Limb-sparing surgery and satisfactory functional outcome is the goal of extremity soft tissue sarcoma (STS) surgery. Tissue defects after tumour excision are often extensive, and microvascular reconstruction is frequently required. METHODS: Seventy-three patients with STS of the leg requiring microvascular reconstruction were treated between 1985 and 2006. Radiotherapy was delivered if the microscopic surgical margin was less than 2.5 cm. RESULTS: Mean follow-up was 65.9 months. Seventy-five free flaps were performed, with a success rate of 95 per cent. One patient died within a month of surgery. Five-year local recurrence-free survival was 82 per cent, metastasis-free survival 59 per cent, disease-free survival 56 per cent and disease-specific overall survival 70 per cent. Fifty-five (75 per cent) of the 73 patients were able to walk normally or had only minor walking impairment. CONCLUSION: Without microvascular reconstruction, amputation would have been necessary in most patients. Microvascular reconstruction is safe and reliable in lower extremity STS reconstruction.
