Targeted Medical Therapy for Vestibular Schwannomas: Evidence, Limits, and Future Directions—A Scoping Review

VSs, particularly in NF2 patients, can cause significant morbidity and are often poorly managed by surgery or radiotherapy. Consequently, targeted medical therapies, especially anti-angiogenic agents, have emerged as valuable alternatives. Bevacizumab shows the most consistent benefits in tumor control, hearing stabilization, and quality of life, despite heterogeneous responses and notable toxicity. Evidence suggests that treatment discontinuation may lead to rapid tumor rebound, highlighting the need for long-term or maintenance strategies and careful monitoring. Future studies are needed to evaluate medical therapy integration with conventional treatments.
