BACKGROUND: Meningiomas are common slow-growing primary intracranial neoplasms attached to the dura mater and are composed of neoplastic meningothelial cells. Increased incidence of meningiomas in women with an increased tumor growth during pregnancy and a possible association with breast cancer suggested that female sex hormones have been involved in the growth of meningiomas. Antihormonal-targeted therapy would be beneficial in such patients. AIM: The aim of this study is to correlate the expression of estrogen receptor (ER) and progesterone receptor (PR) in meningiomas with gender, location, histological subtypes, and grade. MATERIALS AND METHODS: This is a 3½-year prospective and retrospective study of intracranial and intraspinal meningiomas. Clinical details of all the patients were noted from the computerized hospital information system. Immunohistochemistry for ER and PR was performed. Statistical analysis was performed using Chi-square test. RESULTS: During the study period, there were 80 Grade I, 18 Grade II, and 2 Grade III meningiomas categorized as per the World Health Organization 2007 classification. The female-to-male ratio was 1.9:1 and the mean age was 47.8 years. ER was expressed in 2% of meningiomas. PR was expressed in 67.5% of Grade I and 66.6% of Grade II and none of Grade III meningiomas. Brain-invasive meningiomas showed 54.5% PR immunopositivity and negative for ER. CONCLUSION: ER and PR were expressed in 2% and 66% of meningiomas, respectively. Statistically significant relationship was not found between the positivity of PR in females and males of Grade I and Grade II/III meningiomas, intracranial and spinal tumors, Grade I and Grade II/III cases, and various histological subtypes of meningiomas.
背景:脑膜瘤是一种常见的生长缓慢的原发性颅内肿瘤,附着在硬脑膜上,由肿瘤性脑膜内皮细胞组成。女性脑膜瘤的发病率增加,怀孕期间肿瘤生长加快,且可能与乳腺癌有关,这表明女性性激素可能参与了脑膜瘤的生长。抗激素靶向治疗对这类患者有益。
目的:本研究旨在探讨脑膜瘤中雌激素受体(ER)和孕激素受体(PR)的表达与性别、部位、组织学亚型和分级的关系。
材料和方法:这是一项为期 3 年半的颅内和脊髓脑膜瘤前瞻性和回顾性研究。从计算机化医院信息系统中记录所有患者的临床详细信息。对 ER 和 PR 进行免疫组织化学染色。采用卡方检验进行统计学分析。
结果:在研究期间,根据 2007 年世界卫生组织分类,有 80 例Ⅰ级、18 例Ⅱ级和 2 例Ⅲ级脑膜瘤。女性与男性的比例为 1.9:1,平均年龄为 47.8 岁。有 2%的脑膜瘤表达 ER,67.5%的Ⅰ级和 66.6%的Ⅱ级脑膜瘤表达 PR,而Ⅲ级脑膜瘤均不表达。侵袭性脑内脑膜瘤的 PR 免疫阳性率为 54.5%,而 ER 阴性。
结论:脑膜瘤中 ER 和 PR 的表达率分别为 2%和 66%。女性和男性Ⅰ级和Ⅱ/Ⅲ级脑膜瘤、颅内和脊髓肿瘤、Ⅰ级和Ⅱ/Ⅲ级病例以及各种组织学亚型的脑膜瘤中,PR 阳性率与性别之间未发现统计学显著关系。
