BACKGROUND: The long-term prognosis of @entity76 needs to be reviewed. OBJECTIVE: To elucidate the factors influencing @entity5 recurrence or progression and to determine how long these @entity1 with @entity76 require surveillance with neuroimaging. METHODS: A retrospective review of 101 @entity1 surgically treated for a @entity76 and followed up for > 10 years was performed. RESULTS: Mean follow-up was 18.4 years. Total resection confirmed by postoperative imaging was performed in 51 @entity1 (50.5%; group A). Twenty-three @entity1 (22.8%) had surgical total resection; however, equivocal @entity41 was found on postoperative imaging (group B). Subtotal resection leaving a portion of brainstem or cerebellar peduncle was performed in 27 @entity1 (26.7; group C). Of these 50 @entity41 , 16 (32%) showed spontaneous regression and 8 (16%) showed arrested growth. Radiographic recurrence or progression was noted in 29 @entity1 (28.7%). Only 3 of 51 @entity1 (5.9%) of group A with total resection had recurrence, whereas 26 of 50 @entity41 (52%; groups B and C) progressed. The only factor affecting recurrence or progression by multivariate analysis was the extent of surgical resection. All @entity5 recurrence or progression except for 1 (96.6%) occurred within 8 years from the original surgery (range, 2-132 months). CONCLUSIONS: Overall prognosis of @entity76 is good; the 10-year survival rate was 100% and recurrence- or progression-free rate was 71.3% in our cohort. Almost @entity41 showed spontaneous regression or arrested growth in the long term. Eight to 10 years is considered to be a reasonable follow-up period by neuroimaging.
