This is the inaugural Annual Report Preview for the Musculoskeletal Tumor Registry (MsTR). Thank you to the MsTR Steering Committee, the Registry Oversight Committee, and the American Academy of Orthopaedic Surgeons (AAOS) for their contributions and leadership in bringing this Registry to fruition. This exciting and monumental effort reflects collaboration across institutions and subspecialty societies to collect data from across the United States, allowing improved appreciation of survivorship, patient-reported outcomes, and perioperative complications. With an infrastructure that can dovetail with the institutional databases common to many sarcoma centers, this ultimately allows for a streamlined organization of information to improve the quality of patient care.
