NF2 Vestibular Schwannoma Radiosurgery Outcomes for Hearing Preservation, 16 Cases

16 vestibular schwannoma cases in 13 patients with neurofibromatosis type 2 were treated with microanatomy-based low-dose stereotactic radiosurgery between 2002 and 2022. The dataset, shared by figshare admin karger, includes actuarial hearing preservation rates at 3, 5, and 10 years, with a median follow-up of 88 months. Key factors like Gardner-Robertson hearing class and prescription isodose are analyzed for their association with long-term serviceable hearing outcomes.

Use Cases

• Analyze the association between pre-treatment hearing class (Gardner-Robertson) and long-term hearing preservation rates based on the reported actuarial proportions.
• Evaluate the impact of specific radiosurgery parameters, such as prescription dose and isodose line, on treatment effectiveness mentioned in the results.
• Model long-term outcomes for serviceable hearing preservation based on the reported 3, 5, and 10-year actuarial data.
• Study the relationship between cochlear dose (median 5.8 Gy) and hearing deterioration in a low-dose radiosurgery protocol.

Strengths

• Median post-treatment follow-up of 88 months provides long-term outcome data.
• Actuarial proportions for hearing preservation are reported with standard errors at 3, 5, and 10-year intervals.
• Statistical significance (P-values) is provided for associations between treatment factors and hearing outcomes.

Limitations

• The dataset is small, comprising only 16 tumor cases from 13 patients.
• Row count and column-level documentation are unknown, limiting assessment of data structure.
• Data reflects a single-center retrospective analysis, which may limit generalizability.
