Relationship of Myoma Cell Size and Menopausal Status in Small Uterine Leiomyomas

Abstract

Reduction in myoma cell size is significantly associated with postmenopausal status in small uterine leiomyomas and may be an important mechanism for postmenopausal shrinkage of myomas. In addition, the high variability of myoma cell size and N/C ratio may further support the somatic mutation theory (ie, the theory that diverse mutations may account not only for variations in the growth potential of uterine myomas, but also for variations in their cellular details).
