✓ The rates of survival, tumor recurrence, and tumor progression were analyzed in 225 patients with meningioma who underwent surgery as the only treatment modality between 1962 and 1980. Patients were considered to have a recurrence if their studies verified a mass effect in spite of a complete surgical removal, whereas they were defined as having progression if, after a subtotal excision, there was clear radiological documentation of an increase in the size of their tumor. There were 168 females and 57 males (a ratio of 2.9:1), with a peak incidence of tumor occurrence in the fifth (23%), sixth (29%), and seventh (23%) decades of life. Anatomical locations were the convexity (21%), parasagittal area (17%), sphenoid ridge (16%), posterior fossa (14%), parasellar region (12%), olfactory groove (10%), spine (8%), and orbit (2%). The absolute 5-, 10-, and 15-year survival rates were 83%, 77%, and 69%, respectively. Following a total resection, the recurrence-free rate at 5, 10, and 15 years was 93%, 80%, and 68%, respectively, at all sites. In contrast, after a subtotal resection, the progression-free rate was only 63%, 45%, and 9% during the same period (p < 0.0001). The probability of having a second operation following a total excision after 5, 10, and 15 years was 6%, 15%, and 20%, whereas after a subtotal excision the probability was 25%, 44%, and 84%, respectively (p < 0.0001). Tumor sites associated with a high percentage of total excisions had a low recurrence/progression rate. For example, 96% of convexity meningiomas were removed in toto, and the recurrence/progression rate at 5 years was only 3%. Parasellar meningiomas, with a 57% total excision rate, had a 5-year probability of recurrence/progression of 19%. Only 28% of sphenoid ridge meningiomas were totally resected, and at 5 years the probability of recurrence/progression was 34%. In patients undergoing a second resection, the probability of a third operation at 5 and 10 years was 42% and 56%, respectively. There was no difference in the recurrence/progression rates according to the patients' age or sex, or the duration of symptoms. Implications for the potential role of adjunctive medical therapy or radiation therapy for meningiomas are discussed.

Abstract OBJECTIVE Secretory meningiomas are a rare histological subtype of these benign intracranial tumors. Few reports have been published regarding their tendency to develop peritumoral edema. METHODS Between July 1994 and February 1999, 11 patients with secretory meningiomas underwent operations in the Department of Neurosurgery, University of Kiel, Kiel, Germany. The clinical notes and radiological data (computed tomographic and magnetic resonance imaging scans) were reviewed. Immunohistochemistry was used to examine the expression of carcinoembryonic antigen and epithelial membrane antigen as well as progesterone and estrogen receptors. RESULTS Secretory meningiomas were found in 11 (5%) of 214 patients with intracranial meningiomas who were operated on in that period. All 11 patients were women. These patients' mean age was 65 years (range, 51–87 yr). The localization of these tumors was at the convexity in seven patients, at the sphenoid ridge in two patients, and in the olfactory groove and petroclival region in one patient each. Two meningiomas had no edema surrounding them, two meningiomas had a small amount of edema, two had moderate edema, and five had severe edema. No recurrences were observed during the mean follow-up period of 26 months (range, 8–65 mo). Immunohistochemically, all tumors contained pseudopsammoma bodies and reacted with epithelial membrane antigen and carcinoembryonic antigen. The MIB-1 antibody staining index showed a mean of 2% (range, 0–7%). CONCLUSION Secretory meningiomas are rare tumors, and they are mainly localized at the frontal convexity and the sphenoid ridge. They are surrounded by more edema than usual. The preponderance of female patients with this presentation is striking. The expression of carcinoembryonic antigen and epithelial membrane antigen is a characteristic feature of secretory meningiomas. These meningiomas are also positive for progesterone receptors, which has been shown to be a good prognostic factor.
