Fig. 4From: Possible significance of degeneration and decreased expression of progesterone receptor in postmenopausal uterine leiomyomaExpression of hormone receptors in leiomyomas of each group. Hormone receptor expression in leiomyomas showed no significant difference in the Allred score of ER, PRAB, and PRB between groups A and B. Groups A and B had lower expression of PRAB compared to that in group C. Group A: postmenopausal women who underwent surgery for leiomyoma; group B: postmenopausal women incidentally complicated with leiomyoma who underwent hysterectomy; group C: premenopausal women who underwent hysterectomy for leiomyoma without hormonal treatment.
