Changes in pathological markers at three time points during treatment. A Representative IHC images of ER, PR, PRB and Ki67 in sequential endometrial biopsy samples at baseline (T0), at 3–6 months' treatment (T1) and at the end of treatment (T2) from one patient. B IHC scores of above markers at T0, T1 and T2, are presented as scatter plots using paired data. C Median IHC score values at three time points based on data in panels A. * p < 0.05, ** p < 0.01
