Relationship between cytoplasmic FABP7 expression and tumor thickness in primary melanomas

Tumor type	Expression	No of patients	Average depth of growth (mm)	P
SSM	Negative*	41	1.59
	Positive	48	2.17	0.021
NM	Negative*	15	4.32
	Positive	41	4.78	0.697

* Considered negative if < 5% tumor cells showed positive immunoreactivety of FABP7
