Table 2.

Intensity of EphA2 Antibody Staining of Cells in Prostate Tissues in 93 Radical Prostatectomy Specimens

Cell type	Staining Intensity Grade
Cell type	0	1	2	3
Benign epithelium	31 (33%)	61 (66%)	1 (1%)	0 (0%)
High-Grade PIN^*	0 (0%)	20 (22%)	68 (73%)	5 (5%)
Adenocarcinoma^{* †}	0 (0%)	12 (13%)	47 (50%)	34 (37%)

*Indicates percentage of staining intensity was statistically higher compared to that of the normal cells with a P value <0.001 using a Wilcoxon paired signed rank test.

^†The staining intensity was significantly higher compared to high-grade PIN (P < 0.001, Cochran-Mantel-Henszel test).
