Background: Immunohistochemistry (IHC) is used to assess hormone receptor status evaluating hormone receptors (estrogen receptor and progesterone receptor [ER/PR]) in infiltrating ductal carcinoma of breast and determined by scoring systems: Allred (quick) and H scoring system. The present study intended to evaluate the values of these score systems in terms of correlation with Bloom-Richardson grading system of breast carcinoma. Aim: To compare Allred and H scoring systems for evaluating hormone receptors in carcinoma of breast by IHC with modified Bloom-Richardson's grading system. Objective: (1) To confirm and classify histopathology of breast tissue by routine hematoxylin and eosin staining. (2) To obtain grading by Bloom-Richardson grading system. (3) To evaluate breast carcinoma by IHC and assess by Allred and H scoring system of hormone receptors. (4) To compare these scoring systems with Bloom-Richardson grading system. Study Design: Observational, cross-sectional, and comparative. Materials and Methods: BR grade and HR status of 65 surgically resected specimens of carcinoma breast were determined by routine histopathological examination and IHC. Allred and H scoring systems were employed to evaluate HR status. Statistical Analysis: Using Chi-square test and P < 0.05 considered as level of significance. Results: The common grade was Grade II accounting to 73.85% followed by Grade I and Grade III, i.e., 16.92% and 9.23%, respectively. Immunohistochemical analysis was done and most cases belonged to ER(−)/PR(−) category, i.e., 30 cases (46.16%). Allred and H scores were analyzed and compared these scores with Bloom-Richardson Grading system. According to Pearson's correlation matrix, it was observed that a statistical significant correlation was found between Allred and H score system and had an equivalent value for ER and PR (P < 0.0001). Conclusion: The present study had shown that there was no difference between Allred and H score system and had a good correlation with BR grading system as both being semi-quantitative methods and can be practiced regularly for assessment of HR.
