CCAR2 and reproductive system cancer: The findings indicated that patients with reproductive system cancers and DBC1 overexpression were more likely to present with advanced TNM stage (n = 4, RR = 1.760, 95%CI: [1.180-2.627], P = 0.006, I2 = 0.0), distant metastasis (n = 3, RR = 3.918, 95%CI: [1.801-8.522], P = 0.001, I2 = 48.5), and poor histologic grade (n = 3, RR = 1.751, 95%CI: [1.000-3.065], P = 0.050, I2 = 69.9).
