Join us as we count down to 2021 with a SANS question every day this month. Test your knowledge and learn something new each day as you participate. Questions will be posted to Twitter daily.
What is the best estimate of 5-year actuarial tumor control after single-session radiosurgery for skull base meningioma WHO grade I?
The correct answer is 91-95%.
A recent multicenter consortium study reviewed outcomes in 675 cases of posterior fossa meningioma, half of which underwent surgery before radiation, and half of which did not. After treatment to a mean margin dose of 13.6 Gy, at 5 years, tumor control was achieved in 91.2%.
The SANS Lifelong Learning Exams was designed to enhance medical knowledge and self-assessment in neurosurgery, reinforce practice patterns, and recognize knowledge gaps. SANS exams offer 250 questions across specialties worth up to 24 CME.
