Background: It is hypothesized that breast cancer may consist of heterogeneous diseases with different hormonal environments classified by hormone receptor status. Epidemiologic studies evaluating risk factors for breast cancer by hormone receptor status have supported the hypothesis. However, there are inconsistencies in the risk factor profiles by estrogen receptor (ER) and progesterone receptor (PR) across the studies. To clarify the heterogeneity of the disease, it is necessary to understand not only risk factor profiles but also the biologic characteristics such as the relationships among endogenous sex hormone levels and hormone receptors. Methods: We measured serum levels of estrone (E1), estradiol (E2), dehydroepiandrosterone sulfate (DHEAS), and sex hormone-binding globulin (SHBG) in 142 postmenopausal women aged 50 and over with primary breast cancer who had undergone surgical treatment, and investigated the heterogeneity in the relations of endogenous sex hormone levels to hormone receptor status, using the case-series study method. Subjects were categorized into 3 classes based on tertiles of each hormone level in receptor-negative subjects, and odds ratios (ORs) for receptor-positive status compared with receptor-negative status were computed, taking the lowest category as a reference category. Results: There were clear trends toward higher serum levels of E1, E2, and DHEAS in women with PR+ cancer. The case-series approach revealed that PR+ status might be strongly associated with serum sex hormone levels. In particular, the OR of PR+ was large for a high DHEAS level (OR for the highest category = 4.28). No significant association between serum hormone levels and ER status was observed. Conclusion: The association of serum sex hormone levels with hormone receptor status may differ by PR status, but not by ER status. This finding suggests that PR status may be related to the heterogeneity in hormonal environments associated with breast cancer risk.  相似文献

大剂量甲地孕酮治疗晚期乳腺癌的内分泌激素改变   总被引:1,自引:0,他引:1  
目的:了解大剂量甲地孕酮治疗晚期乳腺癌后体内内分泌激素水平改变可能存在的临床意义。方法:选择女性晚期乳腺癌病例共24例以大剂量甲地孕酮(HDMA)治疗(1200mg/d);并测定治疗前后尿17-羟类固醇和17-酮类固醇和血清LH、FSH、E2、PRL、TSH和孕酮(P)水平。结果:LH和FSH降低有显统计意义;E2升高一倍,但没有统计学意义,而PRL升高则有显统计学意义;孕酮轻微下降和TSH轻微升高,无统计意义;24小时尿17-羟类固醇和17-酮类固醇排出量显增加。结论:HDMA可能是通过下丘脑-垂体-肾上腺(性腺)轴的负反馈抑制作用,使LH和FSH分泌下降;体内E2和PRL升高尽管未见与HDMA的临床疗效有确切相关性,但其高泌乳素和高雌激素水平可能对患的预后不利。  相似文献

AIMS AND BACKGROUND: Hormones are considered to be an important factor in the etiology of breast cancer. Serum hormonal profiles of premenopausal and postmenopausal breast cancer patients as well as estrogen receptor (ER) concentrations in breast cancer tissues were examined in an attempt to establish a possible association between hormones and breast cancer risk and to elucidate the biological features of the disease among Egyptian female patients. METHODS: Levels of estradiol (E2), testosterone (T), progesterone (P), LH, FSH, prolactin, T3, T4 and TSH were measured by highly specific radioimmunoassays in the sera of women with breast cancer and compared to those of control subjects. ER concentrations in breast tumor tissues were measured using 125I-radioreceptor assay. RESULTS: Levels of T and prolactin showed a significant increase in both premenopausal and postmenopausal patients. E2 and P levels were significantly increased in follicular premenopausal and postmenopausal patients. Luteal E2 showed non-significant changes, whereas the luteal P level was significantly decreased. No significant alterations were found in the levels of serum LH, FSH, T3, T4 and TSH either in premenopausal or postmenopausal patients. Higher levels of ER were found in the tumors of postmenopausal than in those of premenopausal patients. A positive correlation was found between levels of ER and age of the patients (r = 0.35), whereas a negative correlation was observed between ER and serum E2 (r = -0.26). CONCLUSIONS: This study provides evidence of an association between high levels of serum E2 and T and increased risk of breast cancer in postmenopausal women. Abnormalities in serum P and prolactin are probably associated with a breast cancer risk and ER may be considered as a biochemical marker for breast cancer development.  相似文献

In order to obtain more information on the interrelationships between cytosol estrogen (ER) and progestin (PR) receptors in breast carcinoma, and their distribution according to age, menopausal status and endocrine parameters of the patients, these receptors were measured in 605 primary and 150 metastatic lesions, and correlated with serum levels of estradiol, progesterone, FSH, LH and prolactin in some of these patients. Measurable estrogen receptor (> 3 fmol/mg cytosol protein) was found in 78.0% and progestin receptor (> 10 fmol/mg cytosol protein) in 60.5% of all the samples studied. The receptors were simultaneously present in 57.2%, estrogen receptor only in 20.8%, progestin receptor only in 3.3%, while both receptors were absent in 18.7% of the whole material. In samples from 253 premenopausal patients, measurable ER was found less frequently (71.1% of cases) and its concentration was lower (39.9 ± 5.1 fmol/mg cytosol protein, mean ± SEM) than in 502 postmenopausal patients (82%; 148.2 ± 11.6 fmol/mg). The frequencies of ER-positive samples and ER concentration were rather similar in primary and metastatic lesions, whereas PR was more often present (64 versus 47%) and its concentrations significantly higher (151.2 ± 12.5 versus 102.6 ± 21.1 fmol/mg) in primary than in metastatic tumors. When present simultaneously, there was a significant correlation between ER and PR concentrations in both primary and metastatic lesions independent of the menopausal status of the patient. ER concentration correlated significantly with age in both pre- and postmenopausal patients, while PR concentration correlated with age only in postmenopausal patients. The group with the highest ER values (above 100 fmol/mg cytosol protein) had a significantly lower serum estradiol concentration that the other patients. Serum estradiol values had a significantly positive correlation with cytosol PR content in the samples with a measurable PR. Serum progesterone, FSH, LH and prolactin did not correlate with tumor ER or PR concentrations. We conclude that concomitant assays of ER and PR from a breast carcinoma specimen provide a correct picture of the endocrine characteristics of the tumor independently of the serum concentrations of estradiol, progesterone, FSH, LH and prolactin.  相似文献

BACKGROUND: In breast cancer, there is an inverse relationship between HER2/neu overexpression and receptors for estrogen (ER) or progesterone (PR). Some clinical observations such as the age-related association between hormone receptors and tumour grade, which predicts HER2/neu overexpression, suggest an age-related relationship. PATIENTS AND METHODS: Our study population consisted of 1362 consecutive women receiving primary surgery for non-metastatic invasive breast cancer. We compared the relationship between both hormone receptors and HER2/neu overexpression in different age groups taking other tumour characteristics into account. RESULTS: In a multivariate model, considering the overall group, a negative ER, a negative PR and a high tumour grade were predictive for HER2/neu overexpression (P <0.001). Considering 246 women aged < or =45 years, the only predictor for HER2/neu overexpression in this age category was a high tumour grade (P = 0.003). Considering the 1116 women aged >45 years, ER (P = 0.001), PR (P = 0.001) and tumour grade (P <0.001) were associated with HER2/neu (P <0.001). CONCLUSION: Our findings indicate that the association between ER, PR and HER2/neu overexpression varies with age. The hormone receptors are not an independent predictor for the HER2/neu status in young women while they are in elder patients.  相似文献

In the present paper we have studied the quantitative variations in estrogen (ER) and progesterone receptor (PR) content of breast cancer induced by tamoxifen. In addition to receptors, hormonal levels of estradiol, progesterone, prolactin, FSH, LH and testosterone were also measured. The cases included in our study were consecutively selected among those breast cancers in which an aliquot of the tissue sample sent for analysis of the steroid receptors was positive for cancer and also found to have at least one of the steroid receptors positive, not only in the biopsy but also in the surgical specimen. Following this criterion, we finally collected 14 cases of breast cancer treated daily with 30 mg of tamoxifen during an interval of 3 weeks from the initial biopsy to the final surgery. From our results we can conclude that tamoxifen reduced significantly the ER concentration while no changes were observed in PR values. Concerning hormones, while in premenopausal patients tamoxifen induced a rise in plasma estradiol, in postmenopausal women the only modification observed was a decrease in plasma FSH. The variation in steroid receptor content under tamoxifen therapy may also contribute to the evaluation of the hormone dependency of gynecologic malignancies.  相似文献

Cumulative exposure to estrogen (E) and progesterone (P) over the menstrual cycle significantly influences the risk of developing breast cancer. Despite the dogma that PR in the breast merely serves as a marker of an active estrogen receptor (ER), and as an inhibitor of the proliferative actions of E, it is now clear that in the breast P increases proliferation independently of E action. We show here that the progesterone receptor (PR) and ER are expressed in different epithelial populations, and target non-overlapping pathways in the normal human breast. In breast cancer, PR becomes highly correlated with ER, and this convergence is associated with signaling pathways predictive of disease metastasis. These data challenge the established paradigm that ER and PR function co-operatively in normal breast, and have significant implications not only for our understanding of normal breast biology, but also for diagnosis, prognosis and/or treatment options in breast cancer patients.  相似文献
