Outcome of Therapies for Cerebellar Astrocytomas in Children

Outcome After Surgery

• 85%+ long-term, event-free survival: Long-term, event-free survival is achieved in the vast majority of patients after a gross total tumor resection, with previously reported 5-, 10-, and 25-year survival rates of 90%, 89%, and 85%, respectively (3, 14).   
• <10% recurrence:  Fewer than 10% of patients have a recurrence after gross total resection, but long-term follow-up is necessary, as extremely late recurrences (even 36 years postoperatively) have been reported (10, 14). 
• Normal functional status: Most patients have minimal, if any, long-term disability related to tumor resection (12).
