The MPA test: a reevaluation.

M Dei·G Lippi·M G Pasquini·A Guerrera·V Bruni

Abstract

The response to the administration of Medroxy-progesterone Acetate (MPA) is nowadays widely employed as an indirect index of oestrogen level in women with secondary amenorrhea. The Authors studied the relationship between the response to the MPA test and the activity of the Hypothalamic-pituitary-ovarian axis: they also compared the MPA test with other endocrinological investigations, such as the GnRH and Clomiphene citrate tests. Furthermore, MPA was compared to Noretisterone acetate and to rectally administered pure Progesterone in order to ascertain their pharmacodynamic features.

[Psychogenic amenorrhea].

Any amenorrhoea noticed outside pregnancy, lactation and menopause periods might be of organic or functional origin. Today, non organic amenorrhoea are either called hypothalamic amenorrhoea, more exactly supra hypothalamic amenorrhoea; functional amenorrhoea--this definition being characterized by its lack of any anatomic substratum; or, psychogenic amenorrhoea--an etiologic definition. Like any amenorrhoea, functional or psychogenic amenorrhoea is the consequence of either anovulation or endometrial hypotrophy. Neuroendocrine sciences do open new exciting research perspectives but other ways all the more promising since hormonal mechanics would not be the explanation. Work on the unconscious is indeed the other road leading to these psychogenic amenorrhoea. The term "psychogenic"--of psychological origin--does not mean of unknown origin, provided we recognize the strong link between psyche and soma. Treatment for this kind of amenorrhoea is twofold: medical and psychotherapeutic. Even though psychological etiology is obvious, clinical examination must be rigorous and completed by complementary exams which will guide the therapeutics. This is reassuring to the patient for the gynaecologist she chose to consult is implied, and not the psychotherapist. This reassures us too, because what we care for, as doctors, is first of all the body. Psychotherapeutic support can be provided by the general practitioner or the gynaecologist, both with psychosomatics training, but a multidisciplinary approach must often be worked out.

Amenorrhea in premenopausal women after adjuvant chemotherapy for breast cancer.

Chemotherapy and ovarian ablation both independently improve survival in premenopausal women with hormone-sensitive breast cancer. Amenorrhea is a well-recognized occurrence after chemotherapy. The rate of chemotherapy-induced amenorrhea varies with patient age and chemotherapy regimens administered. However, the impact of chemotherapy-induced amenorrhea on prognosis is still being defined. Older studies in premenopausal women argue that the benefit with chemotherapy is a result of direct cytotoxicity alone. However, studies that restrict outcome analysis to hormone receptor-positive tumors suggest that chemotherapy has a dual mechanism in women with hormone-responsive tumors; indirect endocrine manipulation secondary to chemotherapy-induced ovarian suppression and direct cytotoxicity. The significant health ramifications involved with the induction of premature menopause as well as potential benefits necessitate a comprehensive evaluation of chemotherapy-induced amenorrhea. This review will discuss the incidence of amenorrhea with commonly-used adjuvant chemotherapeutic regimens, the possible benefits of chemotherapy-induced amenorrhea, and the challenges of interpreting the existing data in breast cancer trials.
