The Impact of Chondrosarcoma with Positive Margins and Extraosseous Extension on Patient Outcomes.

Background: Chondrosarcoma accounts for 20% of all bony sarcomas and may present with extraosseous extension (EOE). The presence of an extraosseous component, along with positive surgical margins, has been separately associated with increased risk of local recurrence and decreased survival. This study compared the outcomes between patients with EOE, EOE and positive margins, and a control chondrosarcoma cohort with neither feature.

Surgeon perspectives on a virtual reality platform for preoperative planning in complex bone sarcomas.

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.

Novel Clinical Practice Assessments: Informational Statements by the Musculoskeletal Tumor Society.

Musculoskeletal oncology involves rare diseases. As a result, there is a paucity of literature to guide practitioners. Studies are often clinical experience, retrospective reviews, noncomparative studies, and involve small numbers of patients.
