About this study
Official title: A Phase II Study of Fractionated CyberKnife Stereotactic Radiosurgery to Perioptic Tumors
The purpose of this study is to find out what effects (good and bad) CyberKnife stereotactic radiosurgery has on tumors near the critical structures of the eye (optic apparatus).
The investigators hypothesize that hypofractionated stereotactic radiotherapy via the CyberKnife ® can deliver tumor ablating doses of radiation to perioptic lesions safely and effectively while sparing the adjacent optic apparatus and normal brain tissues from receiving damaging doses of radiation.
Read the detailed description
The CyberKnife system is a type of radiation machine that uses a special system to precisely focus large doses of x-rays (radiation) on the tumor. The device is designed to concentrate large doses of radiation onto the tumor so that injury from radiation to the nearby normal tissue will be minimal.

The record says: finished, as of the sponsor's last update on 25 Jul 2019. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Tumor status (time frame: 5 years). It is what the study was designed to measure, not a finding.
