Filter by:This is a Proof-of-Concept Trial to define the safety, efficacy and feasibility of a cryoanalgesic device (iovera°®) for the treatment of pain in subjects diagnosed with Morton's Neuroma, who have failed conservative therapies.
The purpose of this study is to perform a radiofrequency procedure prior to the removal of morton's neuroma. This procedure would be performed to check in which percentage of the nerve ablation has been performed, and whether the current protocol is performed correctly or parts of the nerve remain intact.
Most vestibular schwannomas are benign and slow-growing. Based on that fact, conservative management with serial imaging is a viable alternative. For patients who undergo treatment because of tumor growth, progressive symptoms, or personal preference, options include serial observation, microsurgical resection, fractionated stereotactic radiotherapy, and stereotactic single-session radiosurgery. Despite improved radiosurgical techniques and lower marginal doses, a recent report has shown a somewhat disappointing 10-year actuarial hearing preservation rate of 44.5%, with hearing loss developing as much as 6 years after. Fractionation of the prescribed dose may takes some advantages from radiobiologic principles to reduce toxicity and maintain tumor control. Staged frame-based radiotherapy using a 12-hour interfraction interval was successfully used at Stanford university and has shown a hearing preservation rate of 77% at 2 years of follow-up. The aim of the present protocol is to evaluate the hearing preservation, the local control and toxicity after single-session (sSRS) or multi-session (3 fractions) radiosurgery (mSRS) by using the frameless robotic CyberKnife® system (Accuray Incorporated, Sunnyvale, CA, USA). In order to investigate about this a randomised controlled double harm (sSRS vs mSRS) trial was designed.
In this research study we are looking at another type of radiation called proton radiation which is known to spare surrounding normal tissues from radiation. The proton radiation will be delivered using fractionated stereotactic radiotherapy (FSRT) to improve localization of the small tumor target. Proton radiation delivers minimal radiation beyond the area of the tumor. This may reduce side effects that patients would normally experience with conventional radiation therapy. In this research study, we are looking to determine the effects of fractionated proton radiotherapy on long-term hearing preservation and controlling tumor growth.
