Treating inoperable early stage lung cancer with the CyberKnife® System

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.

Treating liver metastases from colorectal cancer with the CyberKnife System.
This prospective, multicenter study is intended to establish the efficacy and toxicity of treating unresectable colorectal liver metastases with accurately administered radiation using the CyberKnife stereotactic radiosurgery system.

Prostate Advances in Comparative Evidence (PACE)

This study is an international multicenter randomized study of organ confined low and intermediate risk prostate cancer and is composed of two parallel randomization schemes based on applicability of surgery as a treatment for the patient. Patients for whom surgery is a consideration are randomized to either laparoscopic or da Vinci prostatectomy or CyberKnife prostate SBRT (also known as CyberKnife radiosurgery). Patients for whom surgery is not a consideration are randomized to either conventionally fractionated radiation therapy or CyberKnife prostate SBRT. Efficacy, toxicity and quality of life outcomes will be compared across the pairs in each randomization.
