title: The effect of tumor size and axillary lymph node metastasis on estrogen and progesterone receptors in primary breast cancer.
abstract: We evaluated the estrogen receptors (Er) and the progesterone receptors (Pr) in 209 female patients with primary breast cancer. There is statistically a very highly significant negative correlation between the size of the tumor and the Pr (p = 0.007); large tumor contains low Pr. The same correlation was found with Er, but it was not statistically significant (p = 0.40). There is also a negative correlation between the number of axillary metastatic lymph nodes and Er and Pr, but this was not statistically significant.
