In breast cyst fluid obtained from 50 patients age (47.1 +/- 2.3) sodium, potassium, oestrone (E1), oestradiol (E2) androgens, progesterone, (P) and Epidermal Growth Factor--EGF were determined. Markedly higher oestrogens, progesterone, testosterone, and EGF-levels were detected in cyst fluid than
The relationship between intracystic levels of epidermal growth factor (EGF) and those of dehydroepiandrosterone sulphate (DHEA-S), delta-4-androstenedione (delta-4-A), 17-beta-estradiol (17-beta-E) and progesterone (PROG) have been studied in 77 breast cyst fluid (BCF) samples. EGF and all tested
Circulating levels and cyst fluid concentrations of human chorionic gonadotropin, progesterone and testosterone were measured in 30 premenopausal women with gross cystic breast disease. Specific radioimmunoassay procedures were used. Amounts of human chorionic gonadotropin exceeding 5.0 mIU/ml were
We have previously demonstrated that androgens are potent inhibitors of breast cancer cell proliferation under both basal and estrogen-induced incubation conditions, while they suppress expression of the estrogen and progesterone receptors. To better understand the mechanisms responsible for the
BACKGROUND
Elevated plasma homocysteine concentrations have been reported in a variety of carcinoma, including those of the breast. The risk of breast cancer is higher in patients suffering from gross cystic disease. The breast cyst fluid contains unusual amounts of low- and high- molecular
By applying capillary gas chromatography (GC) and gas chromatography mass spectrometry (GC-MS), a simultaneous quantitation of all important steroid sulfates present in a number of breast cyst fluids, has been obtained. The fact that prevailing androgen sulfate structures in the cyst fluids are
Circulating levels and cyst fluid concentrations of beta-endorphin (beta-EP), estradiol, progesterone, and prolactin were measured by radioimmunoassays in 10 premenopausal women with gross breast cysts. In addition, aspirates and frozen tissue sections from cystic lesions were investigated
The occurrence of a specific glucocorticoid binding activity was investigated in breast cyst fluid (BCF) samples aspirated from 481 women under treatment for breast cystic disease. [3H]cortisol was incubated with BCF at 4 degrees C with and without 100-fold molar excess of non-radioactive steroid in
Gross cystic breast disease (GCBD) is common in women, especially in the age range between 35 and the menopausal years. The present study examined the possible role of progesterone (Pg) in the chorionic gonadotropin (hCG) concentration in GCBD. The breast cyst fluids (BCFs) were drawn by fine needle
Objective. The aim of the study was to analyze the association between levels of adipokines in the breast cyst fluid and in the circulation in relation to the type of cysts. Material and Measurements. A cross-sectional study involved 86 women with breast cysts (42 with simple cysts and 44 with
OBJECTIVE
Increased estrogen activity and prolactin hypersecretion is a hormonal reason for Benign Breast Diseases.
METHODS
To evaluate hormonal disorders in women with gross breast cysts.
METHODS
30 women with gross breast cysts (over 10 mm in diameter) have been investigated. Cytohormonal vaginal
