Abstract/OtherAbstract:
The influence of host age on estrogen (ER) and progesterone (PR) receptor status was studied in 603 tumors obtained from women with confirmed diagnosis of breast carcinoma. Both ER and PR analysis were performed in our own laboratory using standard techniques. Tumors were classified as positive if minimum receptor contents were greater than 10 fmol/mg cytosol protein and if dissociation constants were 1-9 x 10(-10) M or lower. Data from our study indicate that the incidence of receptor negative (ER-PR-) tumors was higher in women from 21 to 40 years of age than in women from 41 to 60 years of age. In women over 60 years of age, the incidence of ER+PR+ tumors was higher than in women under 40 years of age. Interestingly, women from 51 to 60 years of age had a significantly lower incidence (P less than 0.06, 0.0001) of ER+PR+ but higher incidence (P less than 0.01) of ER-PR- tumors than women 41-50 or greater than 60 years of age. Analysis of steroid receptor distribution in relation to host age and obesity showed a definite tendency: in obese women over 60 years of age, frequency of ER+PR+ was significantly greater than in non-obese women of similar age groups. This altered ER and PR distribution in tumors is probably a result of difference in the hormonal milieu associated with host menopausal status and obesity.
