Concomitant Detection of HER2 Protein and Gene Alterations by Immunohistochemistry (IHC) and Silver Enhanced In Situ Hybridization (SISH) Identifies HER2 Positive Breast Cancer with and without Gene Amplification
Figure 6
Correlation of HER2 amplification status by SISH in IHC score 3+ tumors with overall survival.
Overall survival of IHC score 3+ tumors was independent from amplification status by SISH in this cohort (Kaplan Meier curves).
