Operable benign meningioma patients appear to have expected survival that is equivalent to a normal United States population

1543 Background: To compare survival from benign meningioma undergoing resection, with the expected survival from a normal United States population. Materials and Methods: Our patient series consisted of 92 patients with histologically verified benign meningioma (WHO grade I) operated on The University of Texas M. D. Anderson Cancer Center between March 1953 and January 2001. The median age was 48 years (range, 17–93 years), and there was a 2.2 (63/29) preponderance of female patients. The 5 most common tumor sites in descending order was convexity, falx, sphenoid wing, cavernous sinus, and clivus. . Forty-eight patients underwent gross total resection, and 44 patients underwent subtotal resection. Forty patients underwent adjuvant (n=12) or salvage radiotherapy (n=28). The endpoints analyzed were progression-free survival (PFS) and overall survival (OS). PFS and OS rates were calculated using the Kaplan-Meier method. Overall survival curve of the study population is compared with the age, race, and sex-a...
