RESUMO
BACKGROUND: Foot and ankle soft tissue sarcomas (STS) are challenging for reconstruction due to limited surrounding soft tissue and weight-bearing requirements. Currently, there is a paucity of data examining the outcome of flap reconstruction following resection of a foot and ankle sarcoma. METHODS: We reviewed 44 (31 female, 13 male) patients with STS arising from the ankle or foot which required coverage in the form of a free (n = 21), pedicled (n = 13), or rotational perforator flap (n = 10). The mean tumor size was 6 ± 5 cm, with 39 (89%) patients receiving radiotherapy. The mean follow-up was 10 ± 7 years. RESULTS: There were no cases of amputation due to flap failure, with a 10-year limb salvage rate of 84%. Complications occurred in 19 (43%) patients, most commonly wound infections. There was no difference in the incidence of complications between patients undergoing a free flap and pedicled or perforator flap (odds ratio = 0.97, p = 1.0); with no difference in the mean Musculoskeletal Tumor Society (MSTS) score between patients with a free flap versus a pedicled/perforator flap (84% vs. 76%, p = 0.11). CONCLUSION: Flap reconstruction is an essential part of limb salvage for foot and ankle STS. At final follow-up nearly all the patients are ambulatory with an acceptable MSTS score.

BACKGROUND: Limb-salvage surgery combined with radiotherapy has become the primary treatment for soft tissue sarcomas of the extremity. Free functional latissimus flaps (FFLF) are an option to restore function in the setting of volumetric muscle loss. The purpose of the current study was to examine the use of FFLF in patients undergoing resection of thigh sarcoma. METHODS: Twelve patients with a sarcoma involving the hamstring (n = 6), quadriceps (n = 5), or combined (n = 1) defects which included multiple muscle groups were reviewed. This included 9 males and 3 females with a mean age and body mass index of 56 ± 12 years and 31.3 ± 5.7 kg/m2. RESULTS: The mean defect volume and operative time was 3,689 ± 2,314 cm3 and 587 ± 73 minutes. Following reconstruction, the mean knee range of motion (ROM), MSTS93 score, and muscle strength was 89 ± 24°, 90 ± 15%, and 4 ± 1; with 75% of patients ambulating without gait aids. Seven (58%) patients sustained a complication, namely, delayed wound healing (n = 2). CONCLUSION: Although there was a high incidence of complications, FFLF can restore active knee ROM and function, with most patients ambulating without gait aids following reconstruction of large oncologic defects in the thigh.
RESUMO
BACKGROUND/AIM: Reconstruction for soft-tissue sarcomas is complex and often uses soft-tissue flaps. To preserve critical structures, intraoperative radiotherapy (IORT) can be used to boost the total dose to these critical structures and close margins; however, there are limited data on the outcome of soft-tissue reconstruction in patients treated with IORT. PATIENTS AND METHODS: Twenty patients received IORT with soft-tissue flap coverage. There were 14 tumors of the lower extremities and six of the upper, including seven free-flaps and 13 pedicle flaps. Mean preoperative and IORT doses were 49.4 Gy and 10.4 Gy, respectively, with a mean total dose of 59.8 Gy. RESULTS: Seven (35%) patients had a complication, most commonly an infection (n=4, 27%). Total flap loss occurred in one treated with pedicle flap. Four (20%) patients suffered a radiation-associated fracture. At the final follow-up, the mean Musculoskeletal Tumor Society Score was 75±11%. CONCLUSION: Complications and postoperative fractures were common with IORT, however, there were no cases requiring amputation.
