The effect of age on estrogen and progesterone receptor in primary breast cancer

Abstract

We evaluated the estrogen receptors (Er) and progesterone receptors (Pr) in 228 female patients with primary breast cancer by Dextran-Charcol method. Their ages vary from 30 to 91 years. Mean age 60.7 years. (SD: 13.6 years). Er mean was 70.31. (SD:103); there exists a statistically significant correlation between age and Er at p less than .001; older patients have higher Er. Pr mean was 60.73, (SD:128). There is statistically significant correlation between age and Pr at .01 less than p less than .025; older patients have higher Pr. There is also very statistical significant correlation between Er and Pr at p less than 0.1; when Er is high Pr is high.
