Univariate survival analyses indicated that chromosomal instability (CIN), which was determined by parallel SNP6.0 array analyses15, and CDH1 mutation were significant prognostic genomic alterations in our DGCs, consistent with our previous report15 (HRs, 2.3 [95% CI, 1.3‒3.9] and 1.8 [95% CI, 1.1‒3.0], respectively), whereas TP53 mutations were not (P = 0.80, log rank). Here, CDH1 is linked to cervical squamous intraepithelial neoplasia.
