A Prospective Evaluation of Outcomes of Radiosurgical Treatment of Early Stage Non-Small Cell Lung Cancer (NSCLC)

The purpose of this study is to assess the short and long-term outcomes after CyberKnife stereotactic radiosurgery for early stage non-small cell lung cancer (NSCLC) in patients who are medically inoperable.

Stanford is not currently accepting new patients for this trial. You may want to check to see if other locations are recruiting.

The patient must provide a signed and dated written informed consent PRIOR to registration and prior to undergoing any study-related procedures. 11. The patient must provide written authorization to allow the use and disclosure of their protected health information.
