Evaluation of multiparameter histologic diagnosis of gastric cancer

Table 1 Distributions of MG-3c7 and CerbB-2 in gastric cancer tissues

Type	n	MG-3c7				n	cerbB-2
		+++	++	+	-		+++	++	+	-
TACN	30	12	13	5		23	5	7	1	10
AC	12	3	2	2	5	6		1	2	3
SRCC	2				2	3				3
MAC	7				7	2			1	1
GS	4				3	4			2	2
NGM	10				8	6			2	4

TACN: Tubular adenocarcinoma of nipple; AC: Adenocarcinoma; SRCC: Signet-ring cell carcinoma; MAC: Mucous adenocarcinoma; GS: Gastritis; NGM: Normal gastric mucosa.
