We aimed to compare the oncological outcomes of patients who underwent re-excision following unplanned surgery and those who underwent planned surgery. Patients who were referred to our hospital af...

Background: In patients undergoing iliosacral resections, pelvic ring reconstruction can maintain stability of the pelvis and spinal column, which is expected to achieve good functional outcomes. However, no optimal reconstruction method has been established. We aimed to analyze the outcome of pelvic ring reconstruction using double-barreled free vascularized fibular graft (FVFG) and internal fixation after iliosacral resections in children. Methods: We retrospectively reviewed 16 children with pelvic Ewing sarcoma who underwent pelvic ring reconstruction using double-barreled FVFG after iliosacral resection. The fibular graft was placed between the supraacetabular region distally and the remaining ilium or sacrum proximally. The stability of the remaining pelvis and spinal column was provided by minimal spinal instrumentation. Results: Eleven Type-I and 5 Type-I+IV resections were performed for 10 boys and 6 girls, who had a mean age of 13.4 years (range, 10 to 18 years). The mean follow-up was 49.8 months (range, 28 to 96 months). At the time of the final follow-up, 14 patients were alive and 2 patients had died of disease. The mean time for bone union was 9 months (range, 6 to 12 months). Graft hypertrophy was evident in all patients at 12 months. The median Musculoskeletal Tumor Society (MSTS) score at the time of the final follow-up was 80% (range, 60% to 96.6%). Seven patients had complications. Three complications required reoperation: 1 deep infection, 1 hematoma, and 1 wound dehiscence. Three patients had disease relapse in terms of lung metastases. Conclusions: This reconstruction method can achieve a high rate of bone union and can provide good functional outcomes following resection of pediatric pelvic Ewing sarcomas with iliosacral involvement. Complications are usually manageable without a need for revision surgical procedures. Level of Evidence: Therapeutic Level IV.

Objective: This study aimed to investigate amputation-related factors after limb-salvage surgery (LSS) in patients with extremity-located bone and soft-tissue sarcomas and determine the relationship between these factors and patient survival. Methods: In this retrospective study at our institution, patients in whom LSS was first performed because of an extremity-located musculoskeletal sarcoma, and subsequently amputation was carried out for various indications were included. Patient and tumor characteristics, details of surgical procedures, indications of amputation, number of operations, presence of metastasis before amputation, and post-amputation patient survival rates were analyzed. Results: A total of 25 patients (10 men, 15 women; mean age=41.96±21.88 years), in whom amputation was performed after LSS as initial resection of an extremity sarcoma or re-resection(s) of a local recurrence, were included in the study. The leading oncological indication for amputation was local recurrence that occurred in 18 (72%) patients. Non-oncological indications included prosthetic infection in 5 (20%), mechanical failure in 1 (4%), and skin necrosis in 1 (4%) patient. The patients underwent a median of 2 (range, 1–4) limb-salvage procedures before amputation. Distant organ metastasis was detected in 22 (88%) patients during follow-up; in 13 (52%) of these patients, metastasis was present before amputation. A total of 11 (44%) patients were alive at the time of study with no evidence of the disease (n=3) or with disease (n=8), and 14 (56%) patients died of disease. The mean overall and post-amputation survival were 47±20.519 (range, 11–204) months and 22±4.303 (range, 2–78) months, respectively. The median follow-up was 27 (range, 6–125) months. Conclusion: The most common causes of amputation after LSS were local recurrence and prosthetic infection. Patients who underwent amputation after LSS developed a high rate of distant organ metastasis during follow-up and had reduced survival.
