BACKGROUND: To study improvements in outcomes after surgery for intracranial meningiomas.

METHODS: We performed a longitudinal observational study comparing 1469 patients operated on for intracranial meningioma in 4 consecutive time frames (1990-1994, 1995-1999, 2000-2004, and 2005-2010).

RESULTS: Median age at surgery was 58.3 years. Median follow-up was 7 years. Patients in later periods were older than in the earlier ones (odds ratio [OR], 1.19 [1.09-1.32]; P < 0.0005), indicating a trend toward operating on more elderly patients. Before 2000, 42%, 32%, 6%, 19%, and 0.3% achieved Simpson grade (SG) I, II, III, IV, and V, respectively, whereas the SG rates were 35%, 37%, 4%, 23%, and 0.9% after 2000 (OR, 1.18 [1.06-1.30]; P < 0.005). The perioperative mortality (OR, 0.65 [0.46-0.91]; P < 0.05) and worsened neurologic outcome rate (OR, 0.70 [0.60-0.83]; P < 0.0001) were significantly lower in later decades, but the 4 surgical periods were similar regarding postoperative infections and hematomas. Retreatment-free survival (RFS) and overall survival (OS) increased significantly over the 4 time frames (P < 0.05 and P < 0.0001, respectively). Multivariate analysis confirmed the improvement of surgical radicality, neurologic outcome, perioperative mortality, OS, and RFS.

CONCLUSIONS: Meningioma surgery as well as patient population changed over the 2 decades considered in this study. We observed higher rates of gross total resection in the later period and the perioperative outcomes improved or were unchanged, which signifies better long-term outcomes, RFS, and OS.
