Table 2 Shows methodology of scoring of immunohistochemistry for various proteins expressed in normal and renal cancer
Cytoplasm staining | Score | Interpretation |
X | Core loss | |
N | Normal renal tissue | |
0 | No uptake of stain | |
1 | Diffusely or focally weak uptake of the stain | |
2 | Diffusely or focally moderate uptake or focally intense | |
3 | Diffusely intense | |
Nuclear staining | Score | Percentage Nuclei Stained % |
1 | 0–10 % | |
2 | >10 but <50 % | |
3 | ≥50 % |
