Inorder to determine the rate of expression of ER/PR in invasive breast cancer we have reviewed the results of invasive breast cancer cases. A total of 456 breast cancer cases were tested for ER and PR at Tikur Anbessa specialized Hospital, Addis Ababa, from 2008 – sept.,2010G.C.

63.7% were ER positive and 49.2% were PR positive.

The expression of both ER and PR is seen in higher rates with male breast cancer than with female breast cancer. Disease progression was seen with higher frequency with lymph node involvement and it is statistically significant (p=0.118), increasing tumor stage statistically significant (p=0.018), invasive lobular carcinoma not statistically significant (p=0.211), surgical margin involvement not statistically significant (p=0.06), and higher tumor histologic grade statistically significant (p=0.045) and with ER positivity statistically significant (p=0.015).

Large number of female breast cancer patients had history of hormonal contraceptive use. (42.6%)
