HISTOPATOLOGICAL SPECTRUM OF BREAST CARCINOMAS AND CORRELATION OF HISTOLOGICAL GRADE WITH ER, PR, HER2NEU STATUS IN A TERTIARY CARE CENTRE OF EASTERN INDIA

Background: Carcinoma of the breast is a truly complex disease with a large intratumoral heterogeneity, leading to markedly variable clinical
course and response to treatment modalities.
Prognosis and management of breast cancer are influenced by variables such as stage, grade, hormone receptor status of estrogen(ER),
progesterone(PR) and Human epidermal growth factor receptor2 (HER2/neu) over expression.
Aims and Objectives:To highlight the histomorphological spectrum of breast carcinomas and their ER,PR, HER2NEU status. And also to find out
correlation between their histological grade and the hormone status .
Materials and Methods - 115 breast carcinomas were clinicopathologically and immunohistochemically analyzed in which assessment of Her2/neu, ER, PR had been performed prospectively. Statistical analysis was then used to correlate the above observation.
Conclusion: This study highlights the importance of histopathology and immunohistochemistry in breast cancers not only in diagnosing the lesion
but also in predicting the prognosis and target therapy.
