(A) IHC score 1+—barely perceptible at low magnification (original magnification, x20). (B) IHC score 2+—faint at low magnification (original magnification, x20). (C) IHC score 3+—easily recognizable at low magnification (original magnification, x10). (D) IHC score 1+ (original magnification, x40). (E) IHC score 2+ (original magnification, x40). (F) IHC score 3+ (original magnification, x40). (G) No amplification by FISH. (H) LGA by FISH. (I) HGA by FISH.
