Table 2. Crosstabulated EGFR immunostaining location classes vs Fuhrman nuclear grades.
|
Fuhrman nuclear grade |
||||
|---|---|---|---|---|
| EGFR staining location | 1 | 2 | 3 | 4 |
| No staining | 0 | 11 | 15 | 5 |
| 0.0% | 18.6% | 26.3% | 35.7% | |
| Membranous staining | 3 | 25 | 6 | 2 |
| 75.0% | 42.4% | 10.5% | 14.3% | |
| Cytoplasmic staining | 1 | 23 | 36 | 7 |
| 25.0% | 39.0% | 63.2% | 50.0% | |
| 100% | 100% | 100% | 100% | |
The membranous immunostaining has a statistically significant association with low Fuhrman grades, P=0.001, Fisher's exact test.
