How do you approach conventionally fractionated radiotherapy for treatment of an acoustic neuroma?
What do you utilize for patient immobilization and what are your PTV margins? What MRI sequences do you favor for target delineation?

50.4 Gy in 28 fractions is considered if the patient has serviceable hearing.

For acoustic neuroma/vestibular schwannoma, single fraction SRS is typically used with excellent local control, and good hearing preservation.But in larger tumors, fractionated radiation therapy can be used. University of Heidelberg published on 57.6 Gy in 32 fractions (Combs et al., IJROBP 2005). T...

I used to favour fractionated radiation therapy to 45-50 Gy for acoustics with serviceable hearing based on some excellent articles from Thomas Jefferson, such as Champ C et al, Neurosurgery 2013. But then the single fraction radio surgery data came out with good hearing preservation rates with the ...
Single fraction is the best and safest.
