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.
