ALKBH5 and ovarian cancer: As shown in Table 2, high expression of ALKBH5 was positively associated with ovarian cancer stages (P = 0.019), node metastasis (P = 0.04), distant metastasis (P < 0.001), peritoneal seeding (P = 0.001), ascites formation (P < 0.001), primary tumor origin (P = 0.04), histological type (P = 0.037).
