In primary bone sarcoma surgery, tumor surgeons formulate a three-dimensional (3D) surgical plan after analyzing two-dimensional (2D) medical images. It is prone to surgical in accuracy as it is challenging to translate the plan to the operating room in complex cases with distorted anatomies. The surgical inaccuracy with a positive surgical margin may result in an increased risk of local tumor recurrence and patient mortality. Incorrect planes of bone resections may compromise the matching to the bone reconstruction, leading to inferior limb functions.

Computer Assisted Tumor Surgery (CATS) has been developed and applied in Orthopaedic Oncology for the last decade. The CATS approach addresses the surgical inaccuracy and guide surgeons to achieve what has been planned for a tumor-free margin and bone reconstruction. Early results suggested that the CATS technique may help in safe tumor resection and improve surgical accuracy that may offer clinical benefits.

The technology has been evolving to cover the virtual 3D software planner, a dedicated tumor navigation system, 3D printing, and robotic surgery. Institutional logistics tools are also emerging for better users' experience, including a web-based platform for seamless communication of the health care teams and simulation tools for patients' communication of their surgical plan. The development targets personalized precision tumor surgery in the future. The CAOS oncology group connects passionate tumor surgeons, engineers, and researchers to develop and evaluate innovative solutions for better care in orthopedic oncology. We aim to builda CAOS oncology ecosystem with stakeholders through interdisciplinary teams collaboration, Research, and Development, Education, and Training.
