Background and objectives: Treatment of primary bone and soft tissue sarcomas typically includes complete surgical resection with or without adjunctive modalities. Despite best efforts, for the most challenging clinical scenarios such as axial or pelvic sarcoma, five-year survival rates are reported to be between 27 and 40 %. Since quality of resection is a key determinant of oncologic outcomes, it is critical to preoperatively plan the surgical approach to improve resection accuracy, ensure sufficient surgical margins, and reduce the risk of local or metastatic recurrence. The computer conversion of 2-dimensional (2D) computerized tomography (CT) and magnetic resonance imaging (MRI) to a three-dimensional (3D) virtual reality (VR) avatar image may allow improved preoperative estimation of tumor size, location, adjacent anatomy, and spatial understanding of the tumor without relying on surgeon experience, memory, and imagination. The purpose of this study is to investigate the utility of a virtual reality platform in preoperative planning and surgical approach in a retrospective cohort of pelvic bone sarcoma cases. Methods: , defined as positive gross or microscopic margins. Four cases of pelvic bone sarcoma were chosen for retrospective review by fellowship-trained orthopedic tumor specialists. For each case, participants first studied conventional 2D preoperative CT images and answered a questionnaire pertaining to objective case parameters. Participants then interacted wit...
