Comparison between positivity impact of Estrogen receptors and Progesterone receptors in treatment of early Breast Cancer patients

ABSTRACT

Background:Estrogen [ER] and progesterone [PR] are important factors in prognosis and treatment of breast cancer patients. Many studies suggest that disease free survival [DFS] differs when one of these receptors is positive and the other is negative. We aim to study the impact of positivity of estrogen receptors comparing with progesterone receptors on DFS in early breast cancer
