Background: Breast carcinoma is a leading cause of death among women. Factors such as estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor (HER-2/neu) have important prognostic and predictive value. Aim: The aim of the study is to demonstrate ER, PR, and HER-2/neu expression in breast cancer specimens and to correlate these expressions with other prognostic factors such as tumor size, type, grade, and lymph node status. Methods: This prospective study included 70 cases of female breast carcinoma. Histopathological evaluation of all cases done and tumor size, site, presence, or absence of lymph node was recorded. Typing of tumor, grade, and lymph node status were determined. Immunohistochemical staining for ER, PR, and HER-2/neu of breast lesions was done, and the data were analyzed to find out any correlation of expression of ER, PR, HER-2/neu with the above prognostic factors. Results: The majority of patients were in 41–50 years (44.29%). Most of tumors were 2–5 cm in size and the infiltrating duct carcinoma-not otherwise specified was the commonest type. ER and PR expression decreases (P = 0.02340 and P = 0.02413 respectively), while HER-2/neu expression increases with increase tumor size (P = 0.02289). ER and PR expression were low while Her-2/neu expression was more in higher tumor grade (P = 0.022472, P = 0.04149 and P = 0.03339 respectively). No significant association was identified between ER, PR, HER-2/neu and number of metastatic lymph node. Conclusion: ER, PR, and HER-2/neu status correlates well with histopathological grading and tumor size. However, no significant association is seen with cancer type and lymph node status.
