Correlation of combined protein expression scores of SOX2 and nuclear β-catenin expression with lymph-node metastases and distant spread. Percent-values are given in parentheses.

	Nodal status			Distant metastases
Protein expression profile	N0	N+	p	M0	M1	p
SOX2 and β-catenin low	32 (28.1)	28 (24.6)	0.02	40 (35.1)	20 (17.5)	0.001
SOX2 low and β-catenin high	15 (13.2)	15 (13.2)		10 (8.8)	20 (17.5)
SOX2 high and β-catenin low	5 (4.4)	11 (9.6)		6 (5.3)	10 (8.8)
SOX2 and β-catenin high	0 (0)	8 (7.0)		1 (0.9)	7 (6.1)
