Correlation of Clinicopathological Features of Breast Cancer with Molecular Subtypes Taking Ki-67 into Consideration: Single Institution Experience Over 5 Years.

Background: Molecular classification of breast cancer is commonly done to determine response to therapy and cancer prognosis. Aim of the study was to compare prevalence of molecular subtypes of breast cancer in our institute using immunohistochemistry, including Ki-67, and correlate it with clinical and pathological prognostic factors.
