Abstract

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 < 0.001). Radiation alone remained stable over time with a range of 4.8%−6.3% of cases. Observation increased from 45.0% of cases in 2004 to 56.7% of cases in 2012 (P < 0.001). On unadjusted analysis, surgical management was associated with younger age and larger tumor size. The incidence of tumors <2 cm in size increased significantly over the study period from 29.7% in 2004 to 41.7% in 2012 (P < 0.001). After adjusting for tumor size, multivariable analysis demonstrated that the odds of observation as a primary management strategy were greater in 2012 relative to 2004 (odds ratio 1.33, 95% confidence interval 1.21–1.45). 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.
