In the surgical management of primary bone cancer, tumor surgeons formulate a three-dimensional (3D) surgical plan after analyzing two-dimensional (2D) medical images. It is prone to surgical inaccuracy as it is challenging to translate the plan to the operating room in complex cases with distorted anatomies, like in pelvic or sacral tumors or technically demanding operations, like geometric or joint preserving resections. 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

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 by replicating the preoperative planning. The improved surgical accuracy 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 that may include a web-based platform for seamless communication of the healthcare teams and simulation tools for patients' communication of their surgical plan. The development targets personalized precision tumor surgery in the future.

The CAOS oncology focus group is to connect passionate tumor surgeons, engineers, and researchers to develop and evaluate innovative solutions for better care in orthopedic oncology. We aim to build a CAOS oncology ecosystem with stakeholders through interdisciplinary teams collaboration, Research and Development, Education and Training.
