Sensitivity, specificity and accuracy of single and joint detections of serum CEA, SCCA, bFGF levels

Index	Sensitivity (%)	Specificity (%)	Accuracy (%)
CEA	49.6	89.6	75.9
SCCA	51.9	88.1	75.7
bFGF	62.2a	87.3	78.7
CEA+SCCA+bFGF	88.1a,b,c	77.7a,b,c	81.3

^a P < 0.05 compared with CEA;

^b P < 0.05 compared with SCCA;

^c P < 0.05 compared with bFGF.
