Residual tumor volume guides post-surgical treatment paradigm and need for salvage radiotherapy in vestibular schwannoma management

AND OBJECTIVES: Vestibular schwannomas (VS) are slow-growing tumors of the vestibular nerve. Gross total resection (GTR) is recommended for large tumors (> 4 cm), brainstem compression, cranial neuropathy, and hydrocephalus. In select complex cases at our high-volume skull base center, subtotal resection (STR) is pursued for various clinical factors....

Residual tumor volume after vestibular schwannoma surgery may serve as a useful metric for deciding who needs salvage radiotherapy, but the study's design and sample details are not yet fully available; await peer review details before adjusting post-surgical decision protocols.

Optimising the threshold for salvage radiotherapy in vestibular schwannoma could reduce unnecessary treatment exposure while preventing tumor regrowth, directly affecting surgical and neuro-oncology practice.
