Median receptor expression for the histological subtype (a), grade (b) and stage (c). a: Receptor expression and histological subtype. Significant differences were observed for * ER-β: serous vs. endometrioid (p=0.024), # PR-A: serous vs. mucinous (p=0.049) [Mann–Whitney U] and ER-β (all subtypes): p=0.041 [Kryskal Wallis]. b: Receptor expression and tumor grade. Significant differences were observed for * ER-α: G1 vs. G2 (p=0.028), # ER-β: G1 vs. G2 (p=0.002), ° PR-A: G1 vs. G2 (p=0.048), ^ PR-B: G1 vs. G2 (p=0.038) [Mann–Whitney U] and ER-β (G1-G3): p=0.011 [Kruskal Wallis]. c: Receptor expression and tumor stage. Significant differences were observed for * ER-β: FIGO I vs. II (p=0.005), # ER-β: FIGO I vs. III (p=0.001), ° PR-A: FIGO I vs. II (p=0.019), ^ PR-A: FIGO II vs. III (p=0.017), x PR-A: FIGO II vs. IV (p=0.036), “ PR-B: FIGO II vs. III (p=0.017), ~ PR-B: FIGO II vs. IV (p=0.034) [Mann–Whitney U] and ER-β (FIGO I-IV): p=0.011 and PR-A (FIGO I-IV): p=0.030 [Kruskal Wallis].
