Scapular Osteosarcoma Treated by Scapulectomy with or Without Scapular Allograft: A Retrospective Case Series
Abstract
BACKGROUND: Osteosarcoma of the scapula is extremely rare. Hence, there is no consensus regarding its optimal management. In this study, we report the demographics, characteristic features, and outcomes of scapulectomy with or without scapular allograft reconstruction in a series of patients with primary scapular osteosarcoma.
MATERIALS AND METHODS: Twelve patients with primary scapular osteosarcoma who were treated by scapulectomy with or without scapular allograft reconstruction (five and seven patients, respectively) were included. The allograft was fixed in place using a dacron tape without a plate or screw. The function of the shoulder was evaluated using the Musculoskeletal Tumor Society (MSTS) score for the upper extremity and Toronto Extremity Salvage Score (TESS).
RESULTS: The study population included seven (58.3%) males and five (41.7%) females with a mean age of 30 ± 8.2 years. The histologic type of the tumor was osteoblastic in the majority of patients (n = 8, 66.7%). At an average follow-up of 6.5 ± 2.3 years, only one local recurrence (8.3%) occurred in our patients that coincided with lung metastasis. The mean MSTS score was 78.7 ± 3.8% and 66.2 ± 4% in patients with and without scapular allograft, respectively (P = 0.006). The mean TESS was 78.6 ± 5.6 and 68.4 ± 2.4 in patients with and without scapular allograft, respectively (P = 0.005). The overall 5-year survival of the patients was 85.7%.
CONCLUSION: Osteosarcoma of scapula more frequently occurs…
How strong is the evidence?
Evidence Hub reads this as a case series, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health. Reported size: 8 participants or records.
