The effect of tumor size and axillary lymph node metastasis on estrogen and progesterone receptors in primary breast cancer.
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.
