Biopsy specimens from 106 women with primary operable, recurrent or metastatic breast cancer were analyzed in a double blind study designed to compare the results of a new fluorescent antibody method for detection of estrogen receptors with estrogen receptors measured biochemically with
This study investigated the influence of the degree of concentration of breast tumor cytosols on the apparent estrogen receptor content as measured by the Dextran-charcoal assay. It was found that the dilution of cytosols to 1-2 mg protein/ml frequently but not always causes highly underestimated
Estrogen receptors (ER) were analyzed in 63 human breast cancers by immunocytochemical assay, and by enzyme-immunoassay, using monoclonal antibodies against human ER protein, and also by the dextran-coated charcoal method. The specific staining was observed only in the nucleus of cancer cells by the
Estrogen receptor determination was performed on 120 breast cancer cytosols, using the dextran-coated charcoal method (DCC) and an enzyme immunoassay (EIA) to compare the efficiency of the two techniques. A strong correlation was noted between ER concentrations determined by DCC and EIA (P less than
Samples of human breast cancer tissue were analyzed for estrogen receptor content (ER) with a hydroxylapatite method (HAP) as well as a dextran-coated charcoal method (DCC). It was found that both methods revealed artificially low ER concentrations in cytosols with low protein concentration. It was
Estrogen receptor (ER) was estimated immunohistochemically in formalin-fixed and paraffin-embedded tissue from the primary breast cancer in 349 postmenopausal patients with a high risk of recurrence and compared with the results of dextran-coated charcoal assay. There was a highly significant
Misclassification of the oestrogen status of a human breast tumour cytosol, arising from different sources and magnitudes of error in the dextran-coated charcoal (DCC) method, have been investigated using both practical and computer simulated data analysed by Scatchard and Mass Action models. The
The use of preoperative localization procedures for non-palpable breast lesions (NPBL) is becoming more and more widespread, increasing the detection of early breast cancers. From October 1987 to July 1992, at our Institution, 253 patients (pts) with clinically non-palpable lesions underwent
A simplified method for determination of the binding capacity of the sex hormone binding globulin (SHBG-BC) in human serum and its clinical application are described. This method is based on the estimation of the amount of estradiol (E2) bound with SHBG which possessed binding sites with it. After
Estrogen receptor (ER) concentrations have been determined in 191 freshly prepared cytosols from breast cancer biopsies using both the monoclonal enzyme immunoassay (ER-EIA) and the dextran-coated charcoal (ER-DCC) methods in a single laboratory. The concentrations of the ER detected using the two
A new enzyme immunoassay (EIA) for progesterone receptor (PR) has been developed by Abbott Laboratories. To study the correlation of the results from this new technique with the currently existing tritiated-ligand binding assay [dextran-coated charcoal (DCC) method], cytosols from 70 human breast
A commercial preparation of charcoal-stripped adult bovine serum was used to culture MCF-7 cells in estrogen-free media. Use of this stripped adult bovine serum represents an alternative to calf serum which is in more limited supply, and saves charcoal-stripping of serum in the laboratory, which can
The measurement of E2 receptor (E2R) in human breast cancer cytosol is significantly influenced by conditions usually employed in the dextran-coated charcoal assay. The incubation time and temperature have an influence on the rate of binding and stability of the receptor. Since lower temperatures
Surgical specimens from 60 Japanese women with breast cancer were studied histochemically to detect estrogen receptors (ER). Forty-six were analyzed in a double blind study designed to compare the histochemical method using fluorescent estradiol conjugate for detection of ER (FITC method) with
OBJECTIVE
To investigate the effect of activated charcoal-epirubicin suspension (Epi-CH) for treatment of breast cancer and clearance of axillary lymph node metastasis.
METHODS
Sixty patients with breast cancer of stages II-III were randomized into Epi-CH group (n=40) receiving injection with 10 mg
