title: A retrospective study of clinico-pathological spectrum of carcinoma breast in a West Delhi, India.
abstract: BACKGROUND
  Data on the demographic profile of breast cancer patients from Delhi is scarce and whatever is available is from higher referral center. Our hospital caters to patients from an urban population of the lower socioeconomic strata and is a representation of cases at a tertiary care hospital in west Delhi. In Delhi, breast cancer (26.8%) is commonest cancer among the female followed by cervix (12.5%), gallbladder (7.2%), ovary (7.1%), and uterus (3.3%).
  
  
  OBJECTIVE
  A retrospective audit of breast cancer patients presenting at a tertiary referral center from 2004 to 2011.
  
  
  METHODS
  A total of 328 cases diagnosed as carcinoma breast on histopathology from year 2004 to 2011 were retrieved and studied retrospectively with regards to demographic profile and their histological features with estrogen receptor (ER), progesterone receptor (PR), and Her2neu status.
  
  
  RESULTS
  The median age of presentation was 49 years of age. Infiltrating ductal carcinoma (IDC, not otherwise specified (NOS)) was the commonest histopathological variant (81.40%) followed by medullary carcinoma (10.36%) and mucinous carcinoma (2.74%). Triple negative were found to be the commonest group comprising 39.4% of all the cases followed by ER and PR both positive. Pathological tumor, node, and metastasis (TNM) staging showed most common group was T2N0M0 (19.5%) followed by T2N1M0 (17.1%) and T2N2M0 (14%).
  
  
  CONCLUSIONS
  The incidence of breast cancer in the India and include a higher incidence of ER, PR, and Her2neu negative disease in west Delhi.
