Furthermore, low PgR expression levels (HR: 0.40, 95% CI: 0.24–0.68; p = 0.001), premenopausal status (HR: 2.35, 95% CI: 1.18–4.67; p = 0.015), high tumor grade (HR: 1.83, 95% CI: 1.10–3.02; p = 0.019), and the presence of liver metastasis (HR: 2.37, 95% CI: 1.33–4.21; p = 0.003) were significant independent prognostic factors for decreased OS in the multivariate analysis (Table 3). This evidence concerns the gene PGR and neoplasm.
