Nevertheless, there was no significant relationship between increased expression of CBX2 mRNA and OS in endometrial ovarian cancer patients (HR = 3.40×108 (0 - Inf), P = 0.1665), while overexpression of CBX2 mRNA was linked to a better PFS (HR = 0.26 (0.08 - 0.83), P = 0.0149). The gene discussed is CBX2; the disease is ovarian endometrial cancer.
