Introduction
Meningiomas are neoplasms which occur more frequently in women than in men. The women/men ratio is estimated as 3:2 for cases with an intracranial localization of tumors, and even 10:1 for tumors localized within the vertebral canal [8]. The majority of meningiomas show the presence of progesterone receptors (PgR). Rarely, estrogen receptors (ER) in these tumors are also revealed [3,4,11,12,14,16,22]. Some authors indicate a correlation between the rate of growth of these neoplasms and pregnancy and the luteal phase of the cycle, as well as coexistence of meningiomas and breast cancer [1,18,21]. Additionally, there is information about the relation between presence of steroid hormones receptors in meningiomas cells and proliferation index of these tumors [12,19,23,24]. These data suggest a role of sex hormons in the genesis of these neoplasms. In this study, we present results of investigations of progesterone and estrogen receptors immunoexpression in the most frequent WHO grade I histological types of meningiomas (meningothelial MM, fibrous MF and transitional MT ones) and in atypical MA, WHO grade II variant of these tumors.
Material and methods
The postoperative material of tumors was obtained from 64 patients who were operated because of meningioma (28 men and 36 women) (Table I). Histological diagnosis of tumors was formulated according to the criteria of the WHO 2000 classification [15]. The cohort consisted of 46 WHO grade I meningiomas (21 transitional MT, 13 fibrous MF and 12 meningothelial MM variants of the tumors) and 18 WHO grade II - atypical meningiomas MA (Table II). Immunohistochemistry: Immunohistochemical reactions were performed in paraffin slides (4 µm thin). Monoclonal antibodies against ER, PGR, and MIB-1 antibody produced by Novocastra have been used. The reactions were performed according to the procedures suggested by the manufacturer. The MIB-1 labeling index was calculated for every 1000 tumor cells, using a computer analysis system. The PgR immunopositivity was recognized for cells with a nuclear localization of the reaction product. The nuclear and cytoplasmic localization of reaction present at least in 5% of tumor cells was treated as positive for estrogen receptors. Intensity of the immunoreaction was estimated in 0-3 scale using the following system: less than 5% positive cells - PGR 0; 5-10% positive cells - PGR 1; 11-20% positive cells – PGR 2; more than 20% positive cells - PGR 3. Statistic analysis: Mean values and standard deviation have been calculated for each histological type of tumor, and for grade 1 and grade 2 group of meningiomas. Non-parametric tests of the Mann-Whitney U-test and Kruskall-Wallis analysis of variance ANOVA, and chi2 test have been used. For all tests p<= 0.05 was accepted.
Results
PgR positive nuclear immunoreactivity was found in 83% of the investigated tumors. PGR was shown in 100% cases of meningothelial, 95.2% transitional, 77.8% atypical and in 42.2% fibrous types of meningiomas (Table III, Fig. 1). A statistically significant relation in PGR expression was revealed between histologic types of the tumors. The number of PgR immunopositive cells in WHO grade I group of tumors was significantly higher than in the group of atypical meningiomas (Fig. 2). ER was revealed in nuclei and partly in the cytoplasm in 48% of the examined cases, and it had small intensity and focal arrangement (Fig. 3). No statistically significant relation was found between ER and grade of malignancy, nor between ER and histologic variants of tumors. There was also no relation between sex and both of the investigated types of receptors (PgR: Chi2=4.092, df=3, p>0.05; ER: Chi2=2.559, df=2, p>0.05). Additionally, it was shown that the index of proliferation in the group of atypical meningiomas (mean value = 10.8) was significantly higher than in the group of WHO grade I tumors (mean value = 3.7) (Fig. 4 and 5), and that a significant difference exists between the mean age of patients with GI (51.48±13.54), and G II (62.56±11.34) meningiomas.
Discussion

The presence of progesterone and estrogen receptors in cells of meningiomas is well known and has been described for many years [2,5,6,16,20,26]. Like in breast cancer, where the presence of steroids receptors allows to perform additional hormonal therapy, some investigators postulate the possibility of pharmacologic treatment in meningiomas, which would be useful in cases where location of tumor enables total resection, and in cases with a high risk of reccurence like G2 and G3 meningioma [10]. The results of our study confirm that in Polish population PgR immunoexpression is present in above 80% of meningiomas. Most frequently, it is present in the meningoendothelial variant of the tumors. In our study the weakest PgR expression was found in fibrous meningiomas. This might be explained by the differentiation of cells in these tumors more toward mesenchyme than epithelium-like cells [8,13]. PgR immunoexpression intensity showed a reverse relation of statistic significance with the MIB-1 proliferation index. It was lower in atypical G2 meningiomas comparing to G1 cases. These observations stay in agreement with other studies [12,16,27]. Some authors observed the total loss of PgR in the rate of progression and malignization of meningiomas in G2 and G3 cases [4,12,25]. Fewings et all [9] observed that benign meningiomas, which are PgR positive, are less likely to recur. This finding has prognostic and therapeutic implications. It would be interesting to consider if routine PgR examination in meningioma should not be performed, which might be useful in prediction of recurrence. Positive ER expression was shown in 48% of the examined tumors. The immunoreaction was focal, and had smaller intensity than reaction with PgR in every examined case. ER immunoexpression did not show any significant relation with histologic type, PgR and MIB-1 expression. It might indicate the independence of two examined receptors in meningiomas. It is possible, however, that weak immunoreaction of ER in paraffin slides may be related to low sensitivity of the method used by us. In our study we did not find any significant relation between gender and positive ER and PgR immunoreactivity. This result is not in agreement with some other data [15]. Explanation of this discrepancy is difficult, this phenomenon might be related, for example, to wide contraceptive use and hormonal replacement therapy in western population for decades. In Poland, hormonal therapy was introduced about 20 years later, and the number of women using hormones was significantly lower. There are some studies showing that the presence of ER and PgR is more frequent in breast cancer of patients who used hormonal replacement therapy for a long time [17]. Animals research investigations revealed that contraceptives and perinatal treatment with allylestrenol may influence the estrogen receptor state in the uterus [7]. Similar mechanisms may play a role in estrogen and progesterone receptors status in meningiomas. This study describes the presence and ER and PgR in meningiomas in Polish population for the first time. Results of the investigation bring us closer to answer the question what mechanisms regulate meningioma growth, and may allow pharmacologic aid in the treatment of these tumors.
