| Outline of Final Research Achievements |
Our clinical study showed that endometrial cancer (EC) with hyperprolactinemia had higher expression of estrogen receptor (ER)-α and less PTEN mutation. High dose of medroxyprogesterone acetate (MPA) did not sufficiently effect for EC or precancerous lesion with insulin resistance (IR), but that with metformin showed more effective outcome. Continuity of cabergoline after MPA was effective for a prevention of recurrence.
Our basic research showed that prolactin (PRL) promoted higher expression of ER-αand cell proliferation of EC cells. Endometrial cancer mouse model proved that dienogest had almost same effect comparing with MPA which had more side effects.
