Meningiomas are common brain tumors that show a predilection for female and
become more aggressive during pregnancy and menses. Clinical and epidemiological
servations regarding meningiomas suggest a sex hormone dependency of these tumors.
We reviewed the 47 intracranial meningiomas to examine the presence of the
progesterone receptor(PR) by immunohistochemical methods and the relationships
between the PR immunostaining status and other parameters, such as age, sex, tumor
grade, mitotic index, and Ki-67 staining index.
The PR staining status in these tumors was analyzed by immunohistochemistry on
formalin-fixed paraffin-embedded archival tissue sections utilizing the monoclonal
antibody. The results are summarized as follows : 1) fifteen tumors(31.9%) tested were
positive for the PR. 2) patients age and sex had significant relationship with the PR
positive rate of meningiomas(p=0.680, and 0.968, respectively). 3) although the positive
immunostaining rate for the PR in bengin meningiomas (37%) was higher than that in
atypical and mailignant meningiomas(25%). There was no statistically significant
difference between these two groups(p=0.381), and 4) proliferative potentials such as the
Ki 67 staining index and the mitotic index were not correlated with the PR staining
status(p=0.4578 and 0.1981. respectively). We believe that further studies using large
series of patients are needed to elucidate the role of the PR in meningiomas.
