A Comparison of Oncological and Surgical Outcomes in Endoprosthetic Reconstruction Versus Rotationplasty for Pediatric Lower Extremity Bone Sarcomas
Description
The presentation by Jong Min Lee from the University of Toronto discusses a retrospective review comparing oncological and surgical outcomes of two reconstructive options for knee tumors: endoprosthesis and rotationplasty. Lee presents background information indicating that both reconstructive methods are offered at their institution for tumors requiring articular surface sections. The study included 50 patients, with 26 receiving endoprostheses and 24 undergoing rotationplasty, studying demographics, tumor presentations, and treatment responses over an average follow-up of three to four years.
Key findings highlighted that both groups had similar demographic backgrounds concerning age, gender, and tumor pathology, primarily osteosarcoma. While both surgical options achieved negative margins, there were no significant differences in overall survival after five years, with 51.4% survival in the endoprosthesis group and 67.9% for rotationplasty. However, rotationplasty demonstrated some advantages in specific subgroups, particularly in patients without metastases responding well to chemotherapy, revealing fewer complications and no local recurrences, whereas the endoprosthesis group had more complications, including local recurrences and mortalities due to recurrence and metastasis.
In summary, while endoprostheses were associated with more complications, rotationplasty may offer improved survival outcomes under certain conditions, although these findings are preliminary and based on a small patient sample. Lee emphasizes the need for further research with a larger cohort and mentions ongoing studies to assess functional outcomes in these patient groups.
