Using 3D models to improve surgery for children's pelvic and retroperitoneal tumors

Non-interventional Study on the Contribution of 3D Modelling in Surgical Management of Pediatric Retroperitoneal and Pelvic Tumors Compared to 2D Imaging

Observational Assistance Publique - Hôpitaux de Paris · NCT06418243

This study is testing if using 3D models of tumors can help doctors plan surgeries better for children with pelvic and retroperitoneal tumors compared to regular 2D images.

What this trial studies

This study compares the effectiveness of automatically generated 3D models of tumors to traditional 2D images in aiding surgical planning for pediatric patients. Parents, patients, and surgical teams will evaluate the 3D models against standard 2D images through questionnaires. The study aims to enhance understanding and communication regarding tumor characteristics before surgery, utilizing MRI and CT scans as part of routine care. The focus is on children with pelvic or retroperitoneal tumors who require imaging prior to surgical intervention.

Who should consider this trial

Good fit: Ideal candidates are children aged 3 months to less than 18 years with pelvic or retroperitoneal tumors requiring imaging for surgery.

Not a fit: Patients with contraindications for MRI or CT scans, or those needing imaging under general anesthesia, may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to improved surgical outcomes and better pre-operative understanding for families.

How similar studies have performed: While the use of 3D imaging in surgery is gaining traction, this specific approach in pediatric tumors is relatively novel and has not been extensively tested.
