GKRS vs LINAC SRS for vestibular schwannoma (n=85, retrospective): LC 98.8%, no difference in new vertigo, gait disturbance or facial palsy at median f/u 27 mo.
Only CNS today: a retrospective single-institution series finds 12.5 Gy GKRS and 12 Gy LINAC SRS comparable for vestibular schwannoma tumor control and new cranial nerve symptoms. Platform is confounded by center and baseline imbalance (larger GTV, more brainstem mass effect with GKRS); hearing, the endpoint that drives the RT decision, not reported.

- Gamma Knife vs LINAC-based radiosurgery for vestibular schwannoma (retrospective review)Local control 98.8%; no difference in new vertigo, gait disturbance or facial palsy with GKRS (n=36) vs LINAC (n=49) SRS for vestibular schwannoma.
- SWOG S1827/MAVERICKRandomized phase III, LS or ES SCLC: PCI 25 Gy/10 fx + MRI vs MRI surveillance alone; no CFFS or OS results in source tweets.
