The expression of DBC1 predicted a 4.031-fold (P = 0.008, 95% CI; 1.427-11.382) greater risk of death and a 2.540-fold (P = 0.005, 95% CI; 1.135-5.684) greater risk of relapse or death of high-grade serous carcinoma patients (Table 2). This evidence concerns the gene CCAR2 and serous adenocarcinoma.
