Trends in Management of Intracranial Meningiomas: Analysis of 49,921 Cases from Modern Cohort

摘要

Objective We sought to characterize patterns and treatment for intracranial meningiomas in the Surveillance, Epidemiology, and End Results set of cancer registries. Methods SEER data was queried from 2004–2012 for cases of intracranial meningioma using appropriate topography and histology codes. Results A total of 49,921 patients with intracranial meningioma were identified. The vast majority of cases were associated with a benign histology ( n ?= 47,047, 94.2%). There were 21,145 patients (42.4%) who underwent surgical management, 2783 who received radiation alone (5.6%), and 25,993 who underwent surveillance only (52.1%). Surgical management decreased in frequency from 48.8% of all cases in 2004 to 38.3% of cases in 2012 ( P P P Conclusion The incidence of intracranial meningiomas increased, while tumor size at the time of diagnosis decreased. Moreover, the number undergoing no treatment increased as a treatment strategy and was more likely employed for older patients, those of African-American race, and those with smaller tumors.
