Recurrence in craniopharyngiomas: analysis of clinical and histological features

J Clin Neurosci. 2006 May;13(4):438-42. doi: 10.1016/j.jocn.2005.05.013.

Abstract

The aim of this study was to investigate the recurrence patterns and significance of various clinical and histological features as predictors of recurrence in craniopharyngiomas. A series of 234 craniopharyngiomas (156 males, 78 females; age range 1.6-65 years) was reviewed. The mean follow-up period was 18.53 months (range 1-120 months). Peri-operative mortality was 7.4% and tumor recurrence was observed in 26 patients (20.3%). Of the patients with recurrence, one had total tumor excision (recurrence-free survival (RFS) 14 months), four had near-total excision (mean RFS 18.2 months) and 21 had subtotal tumor excision (RFS for symptomatic recurrence 7.1 months). Histologically, an adamantinous pattern was seen in 81.4% of cases and a papillary pattern was seen in 18.6%. Brain tissue was included in 67 cases and brain invasion was noted in 44 (all were of adamantinous histology). No correlation was noted between histopathological subtyping or brain invasion and recurrence. The significant clinical factors predictive of recurrence included the extent of resection, tumor size greater than 4 cm and cystic tumors.
