Estrogen, Progestrone Receptor and Her2/Neu Expressions incases of Breast Cancer
To correlate ER, PR and HER2/neu expressions with established prognostic factors viz. type of tumour, tumour size, tumour grade, tumour necrosis, lymphovascular invasion (tumor emboli), and axillary lymph node metastasis status. To correlate immunehistochemical marker status ( ER, PR and HER2/neu) with clinical details (age and sex) of patients. The investigative research of Progesterone receptor (PR), Estrogen receptor (ER), as well as HER-2/neu expressions in cases of developing breast carcinoma was carried out over a period of 2 years from June 2015 to May 2017 which included 101 breast cancer cases. Palpable breast lump with or without pain were most frequent complaints. Maximum number of breast cancer cases revealed involvement of left breast. It was found that ER and PR expression was strongly correlated. No significant association was found between the presence of ER, PR expression as well as the size of the tumor. ER and PR negativity was associated with breast carcinoma cases having axillary lymph node metastasis. Out of 101 breast cancer cases tumor necrosis was present in 38.61%. However, the occurrence or absence of tumour necrosis in ER, PR expression was not strongly linked. Tumor emboli were noted in 31.68% of cases. In case of breast cancer with tumor emboli decreased ER and PR expression was observed.
