Recurrence After Subtotal Resection of NF‐2‐Associated Versus Sporadic Vestibular Schwannomas: A Matched‐Cohort Analysis

Key Points

This analysis aims to understand tumor recurrence differences between NF-2-associated and sporadic vestibular schwannomas after subtotal resection.
Conducted matched-cohort analysis
Controlled for key confounders
Compared recurrence rates between NF-2 and sporadic cases
NF-2 tumors demonstrate a higher recurrence rate than sporadic tumors
Findings indicate genetic factors significantly influence recurrence risk
Supports lifelong surveillance for NF-2 patients due to elevated risks

Abstract

In this matched-cohort analysis, the intrinsic biology of germline NF2 is a powerful, independent driver of tumor recurrence following STR. This finding, unmasked by controlling for key confounders, suggests that the elevated recurrence risk in NF-2 patients is a direct consequence of the underlying genetic disorder. These results underscore the distinct natural history of NF-2-associated tumors and support the need for lifelong surveillance.
