ST14 and benign neoplasm: The positive expression and high expression rates of ST14 in ovarian cancer were 93.4% (85/91) and 73.6% (67/91), respectively, which were significantly higher than those in normal ovarian epithelial tissue, specifically 21.4% (3/14) and 14.3% (2/14) (P < 0.001, 0.001), respectively; moreover, the high expression rate was higher than that in benign tumors, (38.5%; 5/13; P = 0.01).
