In multivariable analysis, it has been found that pathology (adenosquamous carcinoma/others vs. squamous carcinoma and adenocarcinoma, HR: 7.56; 95% CI [3.49–16.37], p < 0.001), FIGO staging (III–IV vs. I and II, HR: 6.03; 95% CI [3.52–10.34], p < 0.001), chemotherapy (HR: 0.30; 95% CI [0.17–0.52], p < 0.001), β2-microglobulin (HR: 1.25; 95% CI [1.10–1.41], p < 0.001), NLR (HR: 1.17; 95% CI [1.10–1.24], p < 0.001), and Alb (HR: 0.91; 95% CI [0.87–0.96], p < 0.001) were significant independent predictors in multivariable analysis. This evidence concerns the gene HLA-G and adenosquamous carcinoma.
