A 16 year old female presented with pelvic Ewing’s sarcoma. In this case, the tumor was not responding to a cycle of chemotherapy, and it was decided she should undergo a tumor resection procedure prior to a second cycle of chemotherapy.
Complex human anatomy viewed on two dimensional radiographs is conceptually difficult to grasp due to its multi-layered three dimensional arrangements. In particular, planning for a tumor resection in the pelvis is made more difficult due to the complex anatomical structures and deep location of the tumor.
The surgeons planned to access the tumour via a novel approach (usually used by colo-rectal surgeons to remove tumours) which would require additional resources and planning. A 3D model was requested to give a different perspective for the surgery planning.
With access to the 1:1 scale model, the surgeons had dramatically enhanced insights into the patient’s anatomy and pathology, helping them to visualize the tumor dimensions and its proximity to vital structures much better, and enabled them to practice their planned approach ahead of time. This not only transformed the planning for the surgical team, but ultimately the tumor resection was performed with more precision, more quickly, giving the patient the best possible hope for a successful outcome from the second cycle of chemotherapy.
