UNASSIGNED: To analyze the clinical characters, prognostic factors, patterns of relapse and treatment outcomes for @entity2946 in adults. The clinical materials of 73 consecutive adult @entity1 (age, >= 16  years) with @entity2946 were analyzed retrospectively. Follow-up data were available in 62 @entity1 , ranging from 10 to 142  months (median, 78.4  months). Outcome in survival was assessed by the progression-free survival (PFS) and @entity1349 ( @entity1349 ). Univariate and multivariate analysis were performed to determine the prognostic factors. Total or near-total @entity5 resection was achieved in 37 cases (59.7  %), subtotal in 19 cases (30.6  %), and partial resection in 6 cases (9.7  %).Twenty-two @entity1 experienced recurrences, and 45  % percent of all recurrences occurred more than 4  years after initial surgery. The PFS rates at 5 and 8  years were 60.1 and 37.0  %, respectively. The @entity1349 rates at 5 and 8  years were 82.6 and 57.3  %, respectively. In univariate analysis, less @entity5 resection, non-desmoplastic pathology, and brainstem involvement were risk factors for worse PFS and @entity1349 (P  <  0.05). High-risk category was associated with just lower PFS, but not @entity1349 . In multivariate analysis, complete resection and desmoplastic pathology were independently predictive factors of improved PFS and @entity1349 . In @entity2946 , late relapse is common and therefore long-term follow-up is important for evaluating the real impact of treatments. Risk category had prognostic value just for PFS, but not for @entity1349 . Complete resection and desmoplastic histology are independently predictive factors for favorable outcomes.
