Rthp-13. secondary malignancy rates and adverse radiation effects after stereotactic radiosurgery for benign acoustic neuroma: an institutional experience

CONCLUSION:Including L2-L3 patients, 2.2% of patients may develop a secondary neoplasm due to GKRS after 3-year follow-up. 2.9% may develop adverse effects. No secondary neoplasms found in our cohort were malignant, and most were slow-growing, benign neoplasms posing little neurologic threat. Our data suggest that patients may be re-assured that any post-treatment de novo neoplasms are likely to be benign. Our findings are consistent with estimated secondary malignancy rates of .01 to .1% at ten years.
