Performance of a new preloaded fiducial needle to guide radiation therapy of upper gastrointestinal cancers

Background  Insertion of fiducials to outline the targeted lesion allows image-guided radiotherapy, and is best achieved by endoscopic ultrasound (EUS). This study is a performance comparison of the new EUS-guided preloaded fiducial needle against Visicoil fiducials. Methods  Technical success, visibility score, procedural time, costs, and complications for patients who underwent EUS-guided fiducial placement in upper gastrointestinal malignancies were prospectively collected. Results  60 patients with upper gastrointestinal cancers had fiducials (14 Visicoil; 46 preloaded fiducials) inserted for image-guided radiotherapy. Technical success was 100 %, with a shorter mean (standard deviation) insertion time of 0.94 minutes (0.28 minutes) vs. 5.5 minutes (1.9 minutes; P P P Conclusion  Fiducial insertion for image-guided radiotherapy using the new preloaded needle is associated with 100 % technical success, shorter insertion time, and higher visibility, and is more cost-effective than the Visicoil system.
