SADA-21 EXTENT OF RESECTION REMAINS A KEY DETERMINANT OF ONCOLOGIC OUTCOMES IN MINIMALLY INVASIVE TUBULAR RETRACTOR-BASED RESECTION OF BRAIN METASTASES
Abstract Background Minimally invasive tubular retractor systems are increasingly used for resection of brain metastases, but oncologic efficacy remains poorly defined. This technique typically requires piecemeal rather than en bloc resection, which has been associated with increased local recurrence (LR) and leptomeni...
