Breast cancer comprises a group of very diverse diseases, which can be demonstrated at the molecular, histopathological and clinical levels. Aim of the study were to evaluate Cytokeratin 5/6 (CK 5/6) and Epidermal Growth Factor Receptor (EGFR) expression and correlation with the histological grading of breast carcinoma. EGFR and CK 5/6 are easily available and specific IHC substitute for basal markers. Cytokeratin (CK) 5/6 and EGFR markers have been used in a panel format to identify “basal-like” carcinomas. Methods: The study was performed for the expression of CK 5/6 and EGFR by Immunohistochemistry (IHC) in 48 breast carcinoma patients, underwent for radical mastectomy and were correlated with the MBR histopathological tumor grades for any significance. Result: Among 48 breast carcinoma cases, majority were grade II followed by grade III and grade I. However, on statistical analysis of correlation of EGFR and CK5/6 expressions with tumor grades were found to be significant with P value (= 0.032661) with grade III tumour. The result calculated by SPSS software. Conclusions: Expressions of basal markers like CK 5/6 & EGFR were found to be statistically significantly correlated with the histological grading of breast carcinoma with majority cases having grade III tumor.
