Items	55 cases	Positive (%)	Negative (%)	Pearson Chi square	Fisher’s Exact Test^★	P value	McNemar Test ^#
Serum	Positive (%)	28(50.9)	25(45.5)	0.432	0.605	0.515	P<0.001
Serum	Negative (%)	1(1.8)	2(3.6)	0.432	0.605	0.515	P<0.001

^★Statistical results suggest: 2 cells (50.0%) have expected count less than 5. The minimum expected count is 1.45; ^♯McNemar Test's P value is less than 0.001, indicating that EMMPRIN positive rate in cancer tissue and serum were statistically correlated
