| HER2 score | Amplified (Amp) group (n-18) | Nonamplified (Nonamp) group (n-19) |
|---|---|---|
| Negative (0 or 1+) | 11% (2/18) | 42% (8/19) |
| Equivocal (2+) | 28% (5/18) | 37% (7/19) |
| Strongly positive (3+) | 56% (11/18) | 0% (0/19) |
| Heterogeneous (1+, 2+, 3+) | 5.6% (1/18) | 11% (4/19) |
