A long-term follow-up study of extracorporeal irradiated autografts in limb salvage surgery for malignant bone and soft tissue tumors: A minimum follow-up of 10 years after surgery.
JOURNAL OF SURGICAL ONCOLOGY(2020)
摘要
Background and Objectives The aim of this study is to assess the survival, function, radiographic appearance, and modes of failure of extracorporeal irradiated (ECI) autografts in a long-term setting. Methods We retrospectively reviewed 87 patients who were treated for bone and soft tissue tumors using ECI autografts between 1988 and 2009. Results The 56 patients had a minimum follow-up of 10 years, and the median follow-up period was 16.5 years. The reimplantation procedures included 24 osteoarticular grafts, 16 intercalary grafts, 10 autograft-prosthetic composite grafts, and 6 hemicortical grafts. The 15-year graft and event-free survival rates were 76.8% and 47.9%, respectively. Infection and structural failure were the most common reasons for additional surgery. The time for additional surgery was significantly longer in patients with composite grafts (P < .01). The median Musculoskeletal Tumor Society score and the International Society of Limb Salvage score were 80% and 84%, respectively. Conclusions ECI autografts are a durable option for reconstruction after resection of musculoskeletal tumors and provide good function over more than 15 years. Most graft failures occurred within 5 years of the index surgery. However, composite grafts showed a tendency to fail more than 10 years after the surgery.
