Malignant meningioma is rare and classified as Grade III in the WHO classification of CNS tumors. However, the presence of estrogen receptor (ER) in WHO Grade III meningiomas and its correlation with patients’ outcomes are still unclear. In this single-center cohort study, the authors analyzed clinical features, treatment, and prognosis of these malignant tumors in patients with long-term follow-up.


A total of 87 patients who were pathologically diagnosed with WHO Grade III meningiomas between 2003 and 2008 were enrolled in this study and followed for at least 7 years. Clinical information was collected to analyze the factors determining the prognosis.


Twelve patients with rhabdoid, 12 with papillary, and 63 with anaplastic meningioma were included. The mean progression-free survival (PFS) and overall survival (OS) were 56.2 ± 49.8 months and 68.7 ± 47.4 months, respectively. No significant differences were observed among the 3 histological subtypes in either PFS (p = 0.929) or OS (p = 0.688). Patients who received gross-total resection had a longer PFS (p = 0.001) and OS (p = 0.027) than those who received subtotal resection. Adjuvant radiotherapy was associated with OS (p = 0.034) but not PFS (p = 0.433). Compared with primary meningiomas, patients with recurrent disease had worse PFS (p < 0.001). For patients who had malignant transformations, the prognosis was poorer than for patients without malignant transformations for both PFS (p = 0.002) and OS (p = 0.019). ER-positive patients had a significantly worse prognosis than ER-negative patients regarding both PFS (p = 0.003) and OS (p < 0.001), whereas no association between progesterone receptor and patients’ outcomes was observed. Multivariate analysis demonstrated that ER expression was an independent prognostic factor for both PFS (p = 0.008) and OS (p < 0.001).


This retrospective study showed that patients with meningioma with ER-positive expression had a much worse prognosis than those with ER weak–positive or ER-negative status. The results demonstrated that ER is an independent prognostic factor for both PFS and OS of patients with WHO Grade III meningioma. The authors also found that more radical resection of the tumor, as well as postoperative radiotherapy, may prolong patients’ survival time.
