METHODS
Stereotactic radiotherapy was applied to 28 patients with
menengiomas between January 2009 and January 2012. The patients
were administered an average dose of 20 (15-25) Gy with
a CyberKnife machine using an average of 3 (1-5) fractions.
RESULTS
Stereotactic radiotherapy was applied to 12 patients for primary
treatment, 6 patients for residual tumors, and 10 patients for recurrent
tumors. The median follow-up duration after SRT was
24 (12-40) months. Radiological follow up was obtained in
partial response (12 patients), stable response (15 patients) and
progressive response (1 patient). The local control was 96%.
CONCLUSION
The results show that stereotactic radiotherapy with a CyberKnife
is a highly effective and safe treatment option in
menengiomas. SRT is especially more effective for small volume
tumors.
