Figure 2From: Analysis of EGFR, HER2, and TOP2A gene status and chromosomal polysomy in gastric adenocarcinoma from Chinese patients A: Case 36, immunohistochemistry showed HER2 2+ in gastric adenocarcinoma, B: Immunohistochemistry showed HER2 negative control in gastric adenocarcinoma, C: Case 36, Immunohistochemistry showed TOP2A NI (nuclear index) 40% in gastric adenocarcinoma, D: Immunohistochemistry showed TOP2A NI (nuclear index) less than 1% (under expression) in gastric adenocarcinoma, E: Case 36, FISH result showed HER2 (green signal) and TOP2A (red signal) coamplification in gastric adenocarcinoma.
