Discrepancies seen when scoring the HercepTest by eye or using the MDS system
| Sample | HercepTest score | FISH result | Comments | |
|---|---|---|---|---|
| By eye | MDS | |||
| FISH, fluorescence in situ hybridisation; MDS, Micrometastasis Detection System. | ||||
| a | 2 | 3 | Amplified | Would analyse by FISH routinely but MDS accurate |
| b | 2 | 1 | Non-amplified | MDS accurate |
| c | 0 | 1 | Amplified | 2 tumour populations seen: 1 amplified |
| d | 3 | 2 | Non-amplified | MDS accurate |
| e | 2 | 3 | Amplified | Would analyse by FISH routinely but MDS accurate |
| f | 2 | 1 | Non-amplified | MDS accurate |
| g | 2 | 1 | Non-amplified | MDS accurate |
| h | 2 | 1 | Non-amplified | MDS accurate |
| i | 3 | 3 | Non-amplified | HercepTest staining inaccurate |
| j | 3 | 3 | Non-amplified | HercepTest staining inaccurate |
| k | 2 | 1 | Non-amplified | MDS accurate |
| l | 2 | 1 | Non-amplified | MDS accurate |
| m | 2 | 1 | Non-amplified | MDS accurate |
| n | 2 | 1 | Amplified | MDS does not correspond to FISH |
| o | 1 | 2 | Non-amplified | MDS accurate |
| p | 2 | 1 | Non-amplified | MDS accurate |
| q | 2 | 3 | Amplified | Would analyse by FISH routinely but MDS accurate |
| r | 2 | 3 | Amplified | Would analyse by FISH routinely but MDS accurate |
| s | 1 | 2 | Amplified | MDS accurate. Would not analyse by FISH routinely |
| t | 2 | 1 | Non-amplified | MDS accurate |
| u | 1 | 3 | Amplified | 2 tumour populations seen: 1 amplified |
