Diagnostic efficacy of STMN1, MKI67 as biomarker for STMN1, MKI67.

Gene	Expression	Benign	Malignant	SEN (%)	SPE (%)	PPV (%)	NPV (%)
STMN1				100.00	31.48	32.73	100.00
	Positive	37	18
	Negative	17	0
MKI67				77.78	87.04	66.67	92.16
	Positive	7	14
	Negative	47	4
STMN1+ MKI67				77.78	90.74	73.68	92.45
	Positive	5	14
	Negative*	49	4

^*Either STMN1 negative or MKI67 negative.

SEN – sensitivity; SEP – specificity; PPV – positive predictive value; NPV – negative predictive value.
