Expression of the biomarkers in normal, dysplastic, and malignant esophageal tissues
| Biomarker |
% (positive/total) |
||
| Normal | dysplasia | tumor | |
| RAR-β | 94.3 (33/35) | 62.7 (37/59)a | 53.2 (116/218)b |
| P53 | 5.7 (2/35) | 32.2 (19/59)c | 57.8 (126/218) |
| Ki67 | 5.9 (2/34) | 40.7 (24/59)d | 61.9 (135/218) |
a
P = 0.016 vs χ² test between normal tissues and dysplastic tissues.
b
P < 0.0003 vs χ² test between normal tissues and tumor tissues.
c
P = 0.006 vs χ² test between normal tissues and dysplastic tissues.
d
P < 0.0008 vs χ² test between normal tissues and dysplastic tissues.
