Table 2: HER2 status and PID nanoparticle counts.
Among HER2 positive cases diagnosed according to ASCO/CAP 2007, seven cases (with 〇) received anti-HER2 therapy and six cases (with ×) did not. The sign of (*) of cases 29 and 37 next to 〇 means that these cases had recurrence of breast cancer within three years after surgery.
Italics applied to cases 28 and 35 means that PIDs/cell were very low considering their IHC score (3+ according to ASCO/CAP 2013) and ISH (> 2.0); The cells applied with grey means that PIDs/cell varied among the spots.
