“…At the present moment the majority of authors recommend subtotal resection for old patients or when there are factors defying complete removal7,12,17). The critical factors influencing the possibility of radical and safe resection of meningiomas are tumor-vascular relationships and the integrity of the arachnoid plane between the tumor and the brainstem19). In our series, non-skull base location was a significant factor for complete resection.…”

“…The recurrence rate of infratentorial meningiomas is particularly difficult to estimate because of differences in the reported series regarding the rates of radical excision, the methods of assessment of complete removal, the follow-up periods, the average age of the patients and the percentage of patients receiving postoperative radiotherapy19). Some studies have shown that meningiomas may recur after an apparently radical excision, but it is clear that completeness of resection is the main factor preventing regrowth in all locations1,4,17).…”

ObjectiveBased on surgical outcomes of patients with infratentorial meningiomas surgically treated at our institution, we analyzed the predictors for surgical resection, recurrence, complication, and survival.MethodsOf surgically treated 782 patients with intracranial meningioma, 158 (20.2%) consecutive cases of infratentorial location operated on between April 1993 and May 2013 at out institute were reviewed retrospectively. The patients had a median age of 57.1 years (range, 16--77 years), a female predominance of 79.7%, and a mean follow-up duration of 48.4 months (range, 0.8--242.2 months).ResultsGross total resection (Simpson's grade I & II) was achieved in 81.6% (129/158) of patients. Non-skull base location was an independent factor for complete resection. The recurrence rate was 13.3% (21/158) and the 5-, 10-, and 15-year recurrence rates were 8.2%, 12.0%, and 13.3%, respectively. Benign pathology, postoperative KPS over than 90, low peritumoral edema, and complete resection were significantly associated with longer recurrence-free survival rate. The 5-, 10-, and 15-year survival rates were 96.2%, 94.9%, and 94.9%, respectively. Benign pathology, postoperative KPS over than 90 and complete resection were significantly associated with a longer survival rate. The permanent complication rate was 13% (21/158). Skull base location and postoperative KPS less than 90 were independent factors for the occurrence of permanent complication.ConclusionOur experience shows that infratentorial meningiomas represent a continuing challenge for contemporary neurosurgeons. Various factors are related with resection degree, complications, recurrence and survival.

BACKGROUND The transcription factor avian erythroblastosis virus E26 (V‐Ets) oncogene homolog 1 (Ets‐1) is involved in tumor development and progression through the transcriptional regulation of several matrix‐degrading enzyme systems, including matrix metalloproteinases (MMPs). It has been demonstrated that the MMPs are expressed strongly in high‐grade meningiomas. To determine the biologic significance of Ets‐1 in the progression of benign meningiomas, the authors investigated the expressions of Ets‐1 and its target genes MMP‐2 and MMP‐9 in primary and recurrent, Grade 1 meningiomas. METHODS The expression levels of Ets‐1, MMP‐2, and MMP‐9 were examined by immunohistochemistry in 70 Grade 1 meningiomas, including 36 primary tumors without recurrence after 5 years of follow‐up and 17 pairs of primary tumors and subsequent recurrences. RESULTS The results demonstrated higher expression of Ets‐1, MMP‐2, and MMP‐9 proteins in meningiomas with subsequent recurrences compared with meningiomas from patients who had no recurrences (P < .001). In addition, Ets‐1 expression was correlated with the expression of both MMP‐2 and MMP‐9. CONCLUSIONS Ets‐1 may be involved in meningioma recurrence by up‐regulating MMP‐2 and MMP‐9. Increased expression of these genes in World Health Organization grade 1 meningiomas may serve as an indicator for a high risk of recurrence. Cancer 2006. © 2006 American Cancer Society.
