Hormone replacement therapy regimens in chemotherapy-induced premature ovarian failure and the subsequent correction of hormone levels.

OBJECTIVES: Premature ovarian failure (POF) is a consequence of gonadotoxic chemoradiotherapy given in antyneoplasia treatment. In young women it will correlate with menopausal symptoms which tend to appear due to depleted ovarian follicle reserve. DESIGN: It was a case series study that included women 18-50 years old who were treated for malignancy with gonadotoxic chemioradiotherapy. We have measured blood hormonal levels of follicle stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E2) and progesterone within one month of various hormone replacement therapy (HRT). RESULTS: We have observed different kind of hormonal reaction according to FSH, LH, estradiol and progesterone levels due to various hormonal replacement therapy. The administration of various HRT regimens presented with a decrease in the blood concentration of estradiol E2 and progesterone and a concomitant increase of FSH and LH. These findings demonstrate a shift to physiological ranges and a simultaneous improvement of symptoms associated with CI-POF. CONCLUSIONS: The most appropriate therapy needs to be selected according to the patient's alleviation of symptoms and correction of blood hormone levels.

Results in treatment of early breast cancers and the level of selected metalloproteinases.

BACKGROUND: Breast cancer is the most common malignancy in women in the U.S. and Europe. In the early stages of the disease, women are treated surgically, which is supplemented with hormonal therapy, immuno-, chemo- or radiotherapy. Postoperative qualification for further treatment is based on clinical stage, the pathology of the tumor and classic prognostic factors. Despite that, among patients with breast cancer in early stages of clinical advancement, there is a relatively large proportion of observed tumor recurrence. These observations oblige the search for additional prognostic factors that determine the progression of the disease faster, according to which, could emerge a group of women at increased risk of recurrence of the disease. AIM: The aim of this paper is to determine the meaning of the expression of selected metalloproteinases as prognostic factors in breast cancer. METHODS: The study group consisted of 108 patients ages 26 to 86 years treated surgically from 1994 to 2000 because of primary breast cancer in the early clinical stage, ie stage I and II according to TNM classification. RESULTS: Between two of the tested metalloproteinases (MMP-2 and MMP-11) only MMP-2 appears to have prognostic significance in early forms of breast cancer, and its strong expression is associated with shorter survival.
