Estrogen and progesterone receptor status and Her-2/Neu over expression in breast carcinoma with relation to age

ABSTRACT

Carcinoma of the breast is the common malignancy in Pakistani females. The study was conducted to assess estrogen receptor [ER], progesterone receptor [PR] and Her-2/neu over-expression in females with relation to age. Institution based prospective study. This study was carried out at the Histopathology section in the Department of Pathology, LUMHS, Jamshoro from March 2010 to December 2011. Fifty cases of breast carcinoma were selected to evaluate ER, PR and Her-2/neu over-expression by Immunohistochemistry [IHC]. The predominant histologic morphology was Infiltrating duct cell carcinoma. Majority of the cases presented with grade-II [78.7%] with a mean age of 46.5 years. IHC performed on 50 cases revealed ER +ve in 34 [68%] cases with a mean age of 47.5 years and ER -ve in 16 [32%] cases with a mean age of 44.5 years while PR +ve in 30 [60%] cases with mean age of 44.1 years and PR -ve in 20 [40%] cases with a mean age of 50.1 years. Her-2/neu over-expression was found in 15 [30%] cases with a mean age of 41.6 years and Her-2/neu -ve in 35 [70%] cases with a mean age of 48.6 years. ER and PR expression was found at a significant level reflecting a good therapeutic and prognostic value but the frequency of Her-2/neu over-expression was high reflecting a bad prognosis
