Analysis of ABC (D) stratification for screening patients with gastric cancer

Table 4 Histological analysis and ABC (D) stratification based on the status of endoscopic atrophic border

	All patients	Well diff	Poorly diff	P value
No. of patients	95	76	19
Male:female	72:23	58:18	14:5	NS
Age (yr, mean ± SD)	67.9 ± 8.9	70.2 ± 5.8	61.4 ± 12.9	< 0.05
ABC (D) stratification
A: H. pylori (-) PG (-)	10 (10.6%)	8 (10.5%)	2 (10.6%)	NS
B: H. pylori (+) PG (-)	27 (28.4%)	18 (23.7%)	9 (47.3%)
C: H. pylori (+) PG (+)	54 (56.8%)	47 (61.8%)	7 (36.8%)
D: H. pylori (-) PG (+)	4 (4.2%)	3 (3.9%)	1 (5.3%)
Endoscopic atrophic border
Non	2 (2.1%)	2 (2.6%)	0 (0%)	NS
Closed type	21 (22.1%)	15 (19.7%)	6 (31.6%)
Open type	72 (75.8%)	59 (77.6%)	13 (68.4%)

H. pylori: Helicobacter pylori; PG: Pepsinogen; Non: No atrophic change; Well diff: Well or moderately differentiated adenocarcinoma; Poorly diff: Poorly differentiated adenocarcinoma or signet ring cell carcinoma; NS: Not significant.
