SERPINA1 and neoplasm: On multivariate analyses adjusting patient age at diagnosis, initial serum CA-125 level, FIGO stage, residual tumor after surgery, and germline BRCA1/2 mutational status, high expression of AAT, NFKB, and PMVK were identified as independent favorable prognostic biomarkers for PFS (AAT (adjusted hazard ratio (aHR), 0.398; 95% confidence interval (CI), 0.207–0.768; p = 0.006), NFKB (aHR, 0.424; 95% CI, 0.196–0.920; p = 0.030), and PMVK (aHR, 0.430; 95% CI, 0.228–0.809; p = 0.009)).
