Abstract CONTEXT: The data on histological and receptor status in breast cancer in an Indian population is limited as receptor status is not routinely carried out for these patients. In the present study, receptor status was analyzed and it was correlated with morphological prognostic parameters. OBJECTIVE: To analyze the morphological prognostic parameters and its correlation with receptor status in Indian women. DESIGN: The sample consisted of 126 specimens of invasive breast cancer received in department of pathology of our institution with teaching hospital attached to it, situated in South Canara district of, Karnataka, South India between year 2009 and 2011. RESULT: Sixty-seven percent of patients were 50 years or younger. Histological types were invasive ductal carcinoma, not otherwise specified (58.7\%), and overall (15.9\%) were grade 3. Estrogen receptor was positive in 36.5\%, HER/neu was overexpressed in only three cases; 50.0\% were "triple" negative (estrogen receptor, progesterone receptor, HER/neu negative). Estrogen receptor (ER) and progesterone receptor (PR) positivity decreased with increase in tumor grade. There was significant association between tumor size and ER positivity. CONCLUSIONS: Breast carcinoma in our population presents at younger age than Western population. Our results showed very high proportion of triple-negative breast cancers. The tumor size and grade is related to expression of only ER. The findings suggest that women in our population more often have histologically aggressive breast carcinoma at young age, likely to be less susceptible to conventional hormonal and targeted antibody treatment. Detecting and treating this increasing important cause of mortality will be an enormous challenge.
