大肠癌雌激素受体与孕激素受体表达及临床病理学分析

应用石蜡切片免疫组织化学ＢＡ法回顾性观察了６８例大肠癌组织雌激素受体（ＥＲ）与孕激素受体（ＰＲ）的表达。结果大肠癌ＥＲ／ＰＲ阳性率为４５．６％和３８．３％，表明癌组织具有ＥＲ／ＰＲ依赖性。其阳性率与患者的年龄、组织学类型有关，年龄越大肿瘤分化程度越高，阳性率越高，与患者性别无关。认为ＥＲ／ＰＲ可作为判别肿瘤的恶性程度及选择内分泌治疗的指标。

Estrogen and progesterone receptor profile patterns in primary breast cancer

Summary Estrogen (ER) and progesterone receptor (PgR) analyses have been performed in 884 primary, malignant human breast tumor biopsies. Receptor contents were evaluated with respect to age and menopausal status. The frequency of ER + tumors was found to be significantly higher in postmenopausal than in pre/perimenopausal women. Age rather than menopausal status was found to be associated with this difference. The significant association with age was found in the post- but not the pre/perimenopausal women.The frequency of PgR + tumors was found to be significantly lower in the postmenopausal than in the pre/perimenopausal women. Neither age nor menopausal status alone could account for this difference, which appears to be due to a compound effect of the two factors.The distribution of receptor profile patterns is described according to menopausal status. The patterns differ significantly in pre- and postmenopausal women. PgR dominates in the premenopausal tumor while ER dominates in the postmenopausal tumor. This difference is apparent within the subgroup of ER + PgR + patients as well.The current tenets for prediction of recurrent disease utilizing steroid hormone receptor determinations are discussed for the group of ER + PgR + patients.sponsored by The Danish Cancer Society

肝细胞癌患者外周血性激素受体和糖皮质激素受体的含量

为探讨性激素受体(Sex Hormone Receptor)和糖皮质激素受体(Glucocorticoid Receptor.GR)与肝细胞癌(Hepa- tocelular carcinoma.HCC)的关系及其意义,应用放射配体测定13例HCC患者及23例正常人外周血淋巴细胞雌激素受体(Es- trogen Receptor.ER)和雄激素受体(Androgen Receptor.AR)及外周血细胞GR水平.正常人ER和AR分别为616±106和687±109位点/细胞;GR为5360±1684位点/细胞.HCC患者ER和AR分别为968±120和2903±860位点/细胞.HCC伴肝硬化GR为3112±1130位点/细胞、不伴肝硬化为4536±1201位点/细胞.AR水平明显高于对照组,提示HCC可能为雄激素依赖性肿瘤;GR水平与肝硬化负相关,提示GR下降反映肝硬化的程度.     

子宫肌瘤与腺肌瘤组织及患者外周血白细胞ER、PR测定

乳腺癌激素受体测定—直接荧光法与DCC法比较

本文对52例乳腺癌标本中ER和PR进行了直接荧光法(FHC法)及葡聚糖包埋活性碳吸附法(DCC法)的配对分析,二种方法在检测ER和PR以及预测内分泌疗效方面有较好的一致性,结果无统计学差异(P>0.5)。对二种方法结果不一致的原因进行了客观分析。由于直接荧光法可进行受体的细胞定位,可检测胞浆、胞核和胞膜受体,不受癌细胞构成比例的影响,且具有操作简便、设备简单、费用较少的优越性,是一种值得推广运用的方法。     

Gender-related invasion differences associated with mRNA expression levels of melatonin membrane receptors in colorectal cancer

Melatonin inhibits growth and invasive capacity of colon cancer cells in vitro through its membrane (MT1 and MT2) and/or nuclear receptors (RORα). Previous studies showed that this indoleamine is present in both the normal and colon cancer at similar levels. Therefore, we analyzed MT1, MT2, and RORα expression in tumor samples versus normal mucosa (NM) from patients suffering from colorectal cancer (CRC). Given the existence of sex differences in the incidence and pathology of CRC and the involvement of steroid receptors in the oncostatic actions of melatonin in some types of cancer, we also analyzed the expression of androgen (AR) and estrogen receptor (ER) α and ERβ. Finally, we conducted some experiments in colon cancer cell lines to corroborate the experiments carried out in human tumors. We found a decreased expression of MT1, MT2, AR, ERα, and ERβ in tumor samples versus NM, but no changes in RORα expression in the whole cohort of patients. Classifying tumors by stage and gender, MT1, MT2, AR, ERα, and ERβ expression decreased in both early stage and advanced tumors, but only in male patients. On the other hand, MT1 and MT2 expression correlated positively with AR, ERα, and ERβ expression in male patients and with ERα or ERβ in female patients. In vitro, the invasive capacity was higher in cells with the least expression of MT1, MT2, and AR, and nonselective MT1/MT2 agonists inhibited cell growth and invasion. These results could indicate a possible interaction of these pathways.     

100例甲状腺癌中ER,PR表达及分析

目的检测甲状腺癌中ER、PR的表达,并且探讨它们的表达与肿瘤浸润转移的关系。方法应用SABC免疫组化方法,检测100例甲状腺癌中ER、PR的表达。结果甲状腺癌中ER、PR阳性表达分别为67.0％和62．0％,均与细胞分化程度、组织学类型有关,但其阳性表达与年龄、性别无关。无淋巴结转移组的甲状腺癌中ER、PR阳性率为75.4％和70．5％,显著高于有转移组的53．8％和48．7％（P＜0．05）、结论ER、PR可作为肿瘤分化及恶性程度的评价指标,并且能反映预后。     

人胃癌NKM—45细胞株胞浆,胞核性激素受体含量测定及分析

中枢神经系统肿瘤的雌孕激素受体

本文报告了42例中枢神经系统肿瘤的ER、PR状况。其中脑膜瘤10例,胶质瘤15例,神经纤维瘤8例,其他肿瘤9例。42例中,ER阳性者仅3例,占7.1％。PR阳性率:脑膜瘤组为60.0％,胶质瘤组为13.3％,神经纤维瘤组为37.5％,其他肿瘤组为11.1％。脑膜瘤PR含量明显高于胶质瘤、神经纤维瘤以及其他肿瘤。在脑膜瘤组,PR含量明显高于ER含量,提示脑膜瘤可能是孕激素的靶组织。神经纤维瘤组PR阳性率仅次于脑膜瘤,其PR含量也高于ER含量,与脑膜瘤类似。     

Steroid receptor expression in thymomas and thymic carcinomas

BACKGROUND:

Although protein expressions of glucocorticoid receptor (GR), estrogen receptors (ERα and ERβ), progesterone receptor A (PgR‐A), and androgen receptor (AR) were shown to play roles in the growth and differentiation of normal thymus and thymic tumors, to the authors' knowledge their association with patient characteristics and prognosis has yet to be determined.

METHODS:

A series of 140 thymic epithelial tumors (57 type A + AB thymomas, 40 type B1 + B2 thymomas, 6 type B3 thymomas, and 37 thymic carcinomas) were examined for GR, ERα, ERβ, PgR‐A, and AR expression using immunohistochemistry. In addition, the correlation between expression of these hormone receptors and clinicopathologic factors and overall survival (OS) was assessed.

RESULTS:

GR and ERβ demonstrated a high rate of expression in thymomas and thymic carcinomas (82.9% and 76.4%, respectively), whereas rates of ERα, PgR‐A, and AR expression were low (13.6%, 0.71%, and 23.6%, respectively). A significant correlation (P < .05) was found between ERα expression and tumor size and between ERβ expression and tumor stage. Multivariate analyses revealed that histologic subtype (P = .0039), tumor stage (P = .0012), and GR expression (P = .0025) were significantly correlated with the 10‐year OS rate.

CONCLUSIONS:

GR and ERβ demonstrated high rates of expression in thymomas and thymic carcinomas. Furthermore, multivariate analysis revealed that GR expression was associated with better prognosis in patients with surgically resected thymomas and thymic carcinomas. Cancer 2011;. © 2011 American Cancer Society.
