A: Staining intensity | B: Precentage of positive Tumor cells | C: score |
|---|---|---|
0 = no staining | 0 = 0% positive cells | Â |
1 = weak staining | 1 =< 10% positive cells | Â |
2 = moderate staining | 2 = 10 - 50% positive cells | A × B = C |
3 = strong staining | 3 = 51 - 80% positive cells | Â |
| Â | 4 => 80% positive cells | Â |
