CyberKnife frameless Image-Guided high-dose fractionated stereotactic radiosurgery with the synchrony motion tracking module in the treatment of single small peripheral lung tumors

Curative surgery is not an option for many patients with clinical stage I non-small-cell lung carcinoma (NSCLC) because of associated comorbidities. Stereotactic radiosurgery with the CyberKnife® (Accuray Incorporated, Sunnyvale, CA) tumor tracking system may be an option for many of these medically inoperable patients. Here we provide a concise overview of the standard treatment options for stage I lung cancer and a practical summary of the Georgetown University Hospital stereotactic radiosurgery treatment protocol. We review preliminary outcomes for single small peripheral lung tumors uniformly treated with the CyberKnife using the Synchrony® (Accuray Incorporated, Sunnyvale, CA) motion tracking module.
