Pattern of protein staining in tumour versus normal adjacent epithelium.
| Protein marker | Immunoreaction | ||
|---|---|---|---|
| Ki-67 | n | Positive n (%) | P |
| CCR | |||
| NAE | 140 | 34 (24.3) | <0.001 |
| Tumour | 506 | 345 (68.2) | |
| Lymph node | |||
| Normal | 2 | 2 (100.0) | 0.502* |
| Metastasis | 109 | 60 (55.0) | |
NAE: normal adjacent epithelium;n: total number of cases with and without expression of Ki-67; positive n (%): total number of cases with expression of Ki-67 and respective percentage.
*Comparisons were examined for statistical significance using Fisher's exact test (when n < 5).
