Osteoid Osteoma Clinical Trial

Official title: Safety and Feasibility of MR-Guided High Intensity Focused Ultrasound (MR-HIFU) Ablation of Osteoid Osteoma in Children

Status Completed

Clinical Trial Summary

This study looks to examine the feasibility and efficacy of using MR-HIFU to ablate Osteoid Osteoma lesions in children and young adults.

Clinical Trial Description

Osteoid Osteoma (OO) is a benign, but painful, bone tumor commonly occurring in children and young adults. Common treatment options are surgical excision or, more recently, CT-guided radiofrequency ablation (RFA). RFA is less invasive, but it still requires drilling from the skin through muscle and soft tissue into bone. It also exposes the patient and operator to ionizing radiation.

Magnetic Resonance guided High Intensity Focused Ultrasound (MR-HIFU) provides precise and controlled delivery of focused ultrasound energy inside a lesion using an external applicator, without the need for a scalpel or needle. MR-HIFU has been successfully used to treat painful bone metastases in adult clinical trials and one recent report suggests that it can also be used to treat OO.

MR-HIFU ablation of OO may provide a better alternative to surgical resection or RFA as it is completely non-invasive and does not require ionizing radiation. These two qualities of MR-HIFU are especially beneficial in growing children and young adults. Furthermore, MR-HIFU OO ablation is quick, with expected total procedure time of less than two hours. Such short treatments offer additional safety benefits from reduced anesthesia / sedation requirement compared to surgery and RFA ;
