PED expression analysed in the lung cancer tissue microarray
| Histological type | PED expression | Total | |||
|---|---|---|---|---|---|
| Negative | sssMild | Moderate | Strong | ||
| Adenocarcinoma | 1 (2.3%) | 8 (18.6%) | 10 (23.2%) | 24 (55.8%) | 43 |
| Large cell carcinoma | 1 (2.4%) | 2 (4.8%) | 15 (36.5%) | 23 (56.1%) | 41 |
| Small cell carcinoma | 2 (6.6%) | 5 (16.6%) | 7 (23.3%) | 16 (53.3%) | 30 |
| Squamous cell carcinoma | 2 (4.3%) | 11 (23.9%) | 13 (28.2%) | 20 (43.4%) | 46 |
Top number indicates number of cases present in the tissue microarray; the bottom number indicates its relative percentage. PED expression was graded: negative: no staining; mild: 0–33% positively staining cells; moderate: 34–66% positively staining cells and strong: 67–100% positively staining cells.
