Radiotherapy for Growing Vestibular Schwannomas

COMMENT: This prospective international study evaluated long-term tumor control rates in patients with growing vestibular schwannomas that were treated with first-line radiotherapy. This study stands out because it only includes tumors with documented pre-treatment growth (unlike many other studies, which also include non-growing tumors) and because of the large multicenter cohort of patients analyzed. This allows for a more precise assessment of the efficacy of radiotherapy in growing tumors, including the analysis of treatment failure based on different thresholds of tumor growth and surgical conversion.—Robert Hong, MD
