Relationship between expression of laminin and pathological features in human colorectal carcinoma

Table 3 Tumor invasion depth and laminin staining pattern

Depth of invasion	n	Laminin staining pattern
		+ + to + + +	- to +
Mucosa and submucosa	4	3 (75.0%)	1 (25.0%)
Muscularis	32	17 (53.1%)	15 (46.9%)a
Serosa and subserosa	27	11 (40.7%)	16 (59.3%)a

^aP > 0.05 vs tumor not extended beyond the submucosa.
