Differential gene expression profiling of gastric intraepithelial neoplasia and early-stage adenocarcinoma

Table 6 Statistical results of the differential expression of G₀S₂ among tissue samples in immunohistochemical staining data n (%)

	G0S2 < 5(n = 131)	G0S2≥ 5(n = 24)	Pearson χ2 of4 groups
Gastritis (n = 61)1-3	61 (100.0)	0 (0)	P < 0.001
LGIN (n = 24)	21 (87.5)	3 (12.5)
HGIN (n = 40)45	23 (57.5)	17 (42.5)
EGC (n = 30)	26 (86.7)	4 (13.3)

¹Compared with low-grade intraepithelial neoplasia (LGIN), P = 0.005;

²Compared with HGIN, P < 0.001; ³Compared with EGC, P = 0.004;

⁴Compared with LGIN, P = 0.012;

⁵Compared with EGC, P = 0.008. HGIN: High-grade intraepithelial neoplasia; EGC: Early-stage adenocarcinoma.
