The Cox proportional hazards model also showed that high ALDH1A2 expression (hazard ratio = 0.42, 95% confidence interval (CI) = 0.20–0.85, p = 0.016), high tumor stage (hazard ratio = 3.06, 95% CI = 1.18–7.93, p = 0.021), serous cell type (hazard ratio = 2.63, 95% CI = 1.03–6.73, p = 0.042), and old age (hazard ratio = 1.94, 95% CI = 1.06–3.53, p = 0.030) were independent prognostic factors of overall survival. The gene discussed is ALDH1A2; the disease is neoplasm.
