Abstract: Objective To analyze the differences between CyberKnife radiotherapy with different numbers of gold markers.Methods A total of 424 patients undergoing CyberKnife with gold markers from 2013 to 2014 were enrolled and analyzed.In these patients,330 patients with no less than 3 gold markers were assigned to observation group and 94 patients with less than 3 gold markers were assigned to control group.The setup error and treatment error were recorded and analyzed for each patient.Results The mean setup error and mean treatment error were 0.031 mm and 0.314 mm in the observation group and 0.057 mm and 1.122 mm in the control group,respectively.Conclusion Tracking no less than 3 gold markers can substantially improve the accuracy and quality of treatment.
