Table 4.

Comparison of E-cadherin and N-cadherin expression depending on the tissue location (tumor vs. the endocervix) and histological type of endometrial cancer (type I vs. II). Data are presented as n (%). * χ² test, p-values < 0.05 were considered statistically significant; p1—p-value for cadherin expression depending on the location; p2—p-value for cadherin expression in the endocervix depending on the type of endometrial cancer; p3—p-value for cadherin expression in the tumor depending on the type of endometrial cancer.

Endometrial Cancer	Expression in the Tumor	Expression in the Endocervix
		E-Cadherin					N-Cadherin
		Low	High	p1 *	p2 *	p3 *	Low	High	p1 *	p2 *	p3 *
Type I	Low	28 (55)	3 (6)	0.29	<0.001	0.001	4 (8)	4 (8)	0.59	0.19	0.29
	High	16 (31)	4 (8)				26 (51)	17 (33)
Type II	Low	13 (26)	2 (4)	0.01			11 (22)	1 (2)	<0.001
	High	13 (26)	22 (44)				12 (24)	26 (52)
