We aimed to evaluate the patient distribution according to diagnosis, dose and fraction data in four radiotherapy centers in Istanbul with a robotic system. The data of the patients treated in 2010 in these centers were analyzed retrospectively.
METHODS
Five hundred ninety-three patients treated with the
CyberKnife (CK) system during 2010 were included in this
study. The median age of the patients (355 male [59.9%], 238
female [40.1%]) was 55 years (range: 8-87).
RESULTS
CK was used as primary treatment in 348 patients, for reirradiation
in 209 patients, planned boost in 26 patients, and for
recurrence in previous field edge in 10 patients. Total median
dose was 2100 cGy (800-7500 cGy), median dose per fraction
was 800 cGy (200-3750), and median total fraction was
3 (1-10).
CONCLUSION
CK is preferred as a curative or palliative modality in the treatment
of certain malignant and some benign lesions, with appropriate
indications.
