AbstractIn a continuing prospective study, uterine curettage was undertaken on sixty-four patients attending a Menopause Clinic prior to consideration of gonadal hormone therapy. Two of these patients (3.1%) were found to have endometrial hyperplasia, and subsequently they were not given gonadal hormone therapy. Sixty-two patients with normal endometrium at pre-treatment curettage received cyclical oestrogen regimens or sequential oestrogen/progestogen treatments. Four (30.8%) of the thirteen patients in receipt of cyclical 'high-dose' oestrogens developed cystic glandular hyperplasia, whereas none of the patients taking either cyclical 'low-dose' oestrogens (thirty patients) or cyclical-sequential oestrogen/progestogen regimens (nineteen patients) developed endometrial hyperplasia. Among the patients with a normal endometrium, both before and during cyclical gonadal hormone therapy, regular withdrawal bleeding was experienced by thirty-two patients (51.6%). Breakthrough bleeding occurred in nine (14.5%), while twenty-one patients (33.9%) had no vaginal bleeding. Of the four patients with normal endometrium at pre-treatment curettage who subsequently developed endometrial hyperplasia during cyclical 'high-dose' oestrogen therapy, regular withdrawal bleeding was experienced by two patients, and in one of these breakthrough bleeding also occurred. Furthermore, in the four patients who developed endometrial hyperplasia, this condition occurred within six months in two patients and within 9 and 10 months respectively in the remaining two. In the nineteen patients receiving cyclical sequential oestrogen/progestogen regimens, all had regular withdrawal bleeding, while one patient had breakthrough bleeding during sequential therapy. It is concluded that in those climacteric patients who present with severe menopausal symptoms which necessitate the administration of high-dose oestrogen regimes it is necessary either to undertake both pretreatment uterine curettage or to add a progestogen to the oestrogen in a sequential regimen.
