title: 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.
