  1. ER, estrogen receptor; PR, progesterone receptor; HER2, Her2/neu receptor status; IDC, invasive ductal carcinoma; ILC, invasive lobular carcinoma.*ER, PR, and HER2 status as reported on standard surgical pathology reports were determined by immunohistochemistry, or by fluorescent in situ hybridization (FISH) for HER2 according to our institutional standard of practice. ** Cytology from FNABs of patient 5 POST and 12 PRE could not be determined due to low cellularity in the cytologic fractions.
