In 25 cases of breast cancer occurring in perimenopausal age, estrogen receptor (ER) content was determined by the dextran-coated charcoal (DCC) assay and both endogenous-bound estradiol and nuclear DNA concentrations were measured by computerized quantitative analysis on formalin-fixed paraffin-embedded tissue samples. No statistically significant relationship (p greater than 0.05) was found within these parameters. The high incidence (64%) of ER-negative cases in this menopausal age was mainly due (62.5%) to interference of high levels of endogenous estradiol occupying the receptor sites in-vivo. The prevalence of hormone-insensitive and aneuploid cell clones accounted for the remaining true ER-negative tumours (37.5%).
