The use of SBRT for targets that move with respiration were highlighted in many presentations on the CyberKnife System at ASTRO 2012, including SBRT for treatment of lung and liver cancers. J.J. Nuyttens, M.D. and colleagues from Erasmus MC, University Medical Center, Rotterdam, the Netherlands, reviewed over six years of experience treating 240 patients with peripheral early-stage lung tumors with the CyberKnife System. Five-year tumor control in patients who received at least 51 gray (Gy) was 91 percent, and low rates of complications were observed. Anand Mahadevan, M.D. and colleagues from Beth Israel Deaconess Medical Center, Boston, Mass. presented data that supported treatment of primary and metastatic lesions in the liver. This data found SBRT could be delivered to unresectable liver tumors with relatively low toxicity and promising efficacy, in a three-day treatment that allowed patients to continue with ongoing chemotherapy with minimal interruption.The ability for the CyberKnife System to accurately track and correct for unpredictable motion of the prostate was highlighted in 10 presentations at ASTRO 2012 by researchers describing outcomes following CyberKnife prostate SBRT for patients with organ confined prostate cancer. Researchers found patients to have excellent disease control with minimal urinary, bowel, and sexual function toxicity that are in line or better than other radiation and surgical treatments across the various single and multicenter studies presented.
