BACKGROUND Breast carcinoma is the most well-known malignancy in women. Different predictive and prognostic
factors, for example, estrogen receptors (ER), progesterone receptors (PR) and human epidermal growth factor receptor
(Her2neu), and Ki67 could inuence breast carcinoma behaviour, yet to date no authoritative connection has been set up among them and breast
carcinoma subtypes. In this way present study was done to determine the interrelationships of these predictive and prognostic factors for breast
carcinoma.
METHODS In this cross sectional study, a total of 50 lumpectomy, modied radical mastectomy specimens of diagnosed carcinoma breast
were included in this study. The histopathological grading of the breast carcinoma was performed by Nottingham modication of the Bloom
Richardson grading system. All the cases went through immunohistochemistry for ER, PR, Her2neu and Ki67 expression. Association of ER,
PR, Her2neu and Ki67 with different histomorphology was established.
RESULTS The ER positivity was signicantly lower in tumors >5 cm size whereas Ki67was signicantly increased with increased tumor size.
The ER positivity was signicantly lower in high grade tumors as compared to low grade tumors. The positive ER, PR, Her2neu and Ki67 were
comparable in between premenopausal and post-menopausal age groups
CONCLUSION The present study concludes that ER, PR show inverse while ki67 showed a direct relationship with the tumor grade.
Correlation of histomorphology of breast tumor and Her2neu status could not be established.
