| Abstract: | PurposeStereotactic radiation therapy using the CyberKnife® has been introduced in France in 2006. Two treatment modalities are currently available: the first one (Synchrony®) is a real-time fiducial-based target tracking system, while the other (Xsight Lung Tracking [XLT] System®) is completely fiducial-free.Patients and methodsSixty-eight patients were treated for a pulmonary tumor between June 2007 and November 2009. Since august 2008, the XLT System® was used for 26 patients. We report the necessary conditions for the XLT System (position, laterality and size of the tumor), the toxicity and outcome of this treatment.ResultsTwenty-two patients were analyzed. Median follow-up was 6 months (min = 3; max = 16). Local control rate was 100%. The main toxicity was grade grade 1 pulmonary alveolitis (27%). No grade 3 or 4 toxicities were reported.ConclusionThe high local control rate and low toxicity obtained with the CyberKnife® XLT System® suggest that such treatment is an alternative for inoperable patients. |
