Introduction-Breast cancer is the most common cancer and leading cause of death in women. In India, its incidence is rapidly rising over last few decades. Present study is aimed to study the pattern of expression of hormonal receptors and Her-2/neu in invasive breast carcinoma and to correlate estrogen receptor (ER), progesterone receptor (PR) and Her-2/neu expressions with various clinicopathological parameters. Material and methods: The present study was carried out in Department of Pathology, S.C.B. Medical College, Cuttack in the year 2013 taking consecutive 100 cases. Routine H&E staining for histological diagnosis and IHC analysis for ER, PR and Her 2/ neu was carried out in all 100 cases of breast malignancies. Results: 99% of cases are invasive breast carcinoma, not otherwise specify (IDC-NOS). The age ranges from 23 years to 72 years. Majority of tumors are of grade 2 (70%) followed by grade 3 (30%). ER PR and Her-2/neu expression are seen in 45%, 35% and 30% respectively. Triple negative cases comprise 35%. Higher number of grade 2 tumor shows ER, PR positivity as compared to grade 3 tumors. Her-2/neu expression does not show any significant correlation with age or lymph node status of the patient. Conclusion: ER and PR expression in breast cancers in the current study are found to be comparable to the findings of other authors, but the frequency of HER-2/neu expression is slightly higher. Significant correlation is observed between hormonal receptor status and the grade of the tumor. Inverse relationship is found between Her-2/neu expression and ER, PR receptor status. Her-2/neu expression is increased with size and high grade of tumor.
