As shown in Figure 7 and Supplementary Figure 3, except DSS for tumor invasion less than 50% of the muscular layer subgroup, the RPP40 expression level exhibited a significantly prognostic value in different clinicopathological subgroups, including clinical stage III–IV, histological grade G3, the histological type of endometrioid, the primary therapy outcome of CR, residual tumor R0, tumor invasion over 50% of the muscular layer, tumor invasion less than 50% of the muscular layer, age below 60 years old, a BMI less than 30 kg/m2, and postmenopause status. Here, RPP40 is linked to neoplasm.
