As shown in Table 2, high expression of Snail was correlated to patients age (P = 0.019), ovarian cancer stages (P < 0.001), distant metastasis (P < 0.001), peritoneal seeding (P < 0.001), ascites formation (P < 0.001), primary tumor origin (P = 0.038). The gene discussed is SNAI1; the disease is ovarian cancer.
