Abstract

Biomarkers are useful for early detection of breast cancer by screening and for monitoring cancer status in patients during and after anticancer treatment as tumor markers. Especially Her-2/neu, Ki-67, p53 and the steroid receptors (estrogen receptor ER, progesterone receptor PR), have gained increasing interest.

To find ER, PR, Her2neu, expression and correlation

100 histologically confirmed female breast cancer patients in the age group of 18–80 years were recruited. Information on patient's age, menopausal status, disease stage, clinical nodes were noted from the case files.

The histopathological grading of the breast carcinoma was done according to the Nottingham modification of the Bloom Richardson grading system. IHC was performed by using antibodies against the ER, PR, Her2neu,

52 patients belonged to the molecular class Luminal A and were ER+ve and Her-2/neu negative, 22 patients belonged to the molecular class Luminal B and were ER +ve and showed overexpression of Her-2/neu. 16 patients were triple negative and did not express ER, PR and Her-2/neu. 10 patients overexpressed Her-2/neu and did not express ER. No significant correlation was seen between ER and Her-2/neu, and PR and Her-2/neu expression.
