To detect the expressions of matrix metalloproteinase-9(MMP-9), progesterone receptor(PR), Ki-67 and Survivin in the multiple meningiomas (MMs) and explore its genesis, diagnosis and bionomics features.


A total of 66 cases with histological sections of meningiomas retrieved from the archives of Department of Pathology of our hospital, including 30 cases of solitary meningiomas (SMs) and 36 cases MMs, were regrouped as benign, atypical and malignant by hematoxylin and eosin staining according to the World Health Organization classification of nervous system tumors. Immunohistochemistry was performed to detect the expressions of MMP-9, PR, Ki-67 and Survivin in 36 cases of MMs and 30 cases of SMs. And normal brain tissue was selected as a control group. The staining intensity was analyzed quantitatively for the differential expressions of MMP-9, PR, Ki-67 and Survivin between SMs and MMs.


No expression of MMP-9, PR, Ki-67 and Survivin was detected in 5 normal brain tissues, but the expression rates were 100%, 53%, 23% and 88% respectively for significant difference comparing with normal tissue. The result of statistical analysis showed that there was significant difference in the expression intensity of MMP-9 and PR between two groups. The expression intensity MMP-9 in multiple group was significantly higher in MMs than that in SMs (P < 0.01) while PR was lower in MMs than that in SMs (P < 0.05). But no significant difference was found for the expression of Ki-67 or Survivin between two groups.


The detections of MMP-9, PR, Ki-67 and Survivin are helpful in the clinical diagnosis and early detection of meningioma.
