Object: To explore factors affecting the survival rate in patients with meningiomas, the authors used the National Cancer Data Base (NCDB), which includes tumors from approximately 1000 hospitals participating in the American College of Surgeons tumor registry program.
Methods: Analysis included over 9000 cases diagnosed from 1985 to 1988 and 1990 to 1992. Survival estimates were computed and prognostic factors were identified using a proportional hazards model.
