EGFR FISH findings in primary gastric cancers and their metastases in 7 cancers with EGFR amplification.^a“Tumor” indicates the cases number referred to in the text. ^bThe FISH results of individual tissue spots are indicated by integers reflecting the copy numbers of centromere 7/EGFR (i.e. 2/20, black face) in the primary and metastases spots. Green color in the primary/metastases spots area indicates high-level EGFR amplification, and blue color indicates negative IHC findings. ^cBold black outline in the “metastases spots” highlights spots that were derived from the same metastasis.
