Noninvasive test for the diagnosis of ovarian hormone-secreting-neoplasm in postmenopausal women.

CONTEXT

The diagnosis of ovarian hormone-secreting neoplasm in postmenopausal women is currently based on imaging modalities and selective venography. However, these diagnostic tests are not always accurate. In order to improve and simplify the diagnosis, we propose a noninvasive hormonal test.

OBJECTIVE

To report our experience using noninvasive hormonal test for the diagnosis of ovarian hormone producing tumor in two postmenopausal women.

DESIGN AND INTERVENTION

Evaluation of androgen and estradiol serum levels following 1. Adrenal hormonal depression, 2. ovarian hormonal depression and 3. ovarian hormonal stimulation.

SETTING

Tertiary care medical center.

MAIN OUTCOME MEASURES

Changes in androgen and estradiol levels.

RESULTS

In the first case, total testosterone, free androgen index and estradiol serum levels decreased following ovarian depression by GnRH-antagonist (6.9 nmol/L, 67 nmol/L and < 70 pmol/L, respectively) and subsequently increased after ovarian stimulation with LH (11.5 nmol/L, 117 nmol/L and 176 pmol/L, respectively). Histological evaluation revealed steroid cell tumor in one ovary. In the second case, estradiol serum levels decreased following ovarian depression by GnRH-antagonist (73 pmol/L) and subsequently increased following ovarian stimulation with FSH (118 pmol/L). Histological evaluation revealed granulosa cell tumor in one ovary.

CONCLUSIONS

To our knowledge, these are the first cases of ovarian hormone-producing tumors in postmenopausal women diagnosed by noninvasive hormonal test. The proposed test can be considered in postmenopausal women suspected of having androgen and/or estrogen producing tumors.
