Abstract | INTRODUCTION: MATERIALS AND METHODS: In the present study we studied the hormonal profile in 303 sporadic breast cancers and BRCA1 protein expression in these patients along with its clinico-pathological correlation. RESULTS: In our patient population, Triple negative Breast carcinoma (TNBC) (104/303; 34.3%) was the most common luminal subtype followed by Luminal A 74/303; 24.4%), Her2 enriched (65/303; 21.5%), and Luminal B (60/303; 19.8%) respectively. This contrasts with many western studies which commonly report Luminal A being the largest subgroup. BRCA1 protein loss was more prominently seen in TNBC (64/104;61.5%) highlighting the possibility that high grade tumors are more susceptible to some epigenetic modifications leading to higher likelihood of loss of BRCA1 protein. CONCLUSION: Hence, we conclude that like hereditary cases of breast carcinoma with BRCA1 mutation; BRCA1 loss is also more likely in sporadic TNBC cases.
