Notes de l'éditeur

  1. Ovarian production of oestrogen is under the influence of the gonadotrophins, follicle stimulating hormone (FSH) and luteinising hormone (LH), both produced by the pituitary gland Goserelin binds to LHRH receptors in the pituitary cell. Following an initial LH surge, there is ‘internalisation’ (or down-regulation) of LHRH receptors and LH synthesis is inhibited The reduction in LH production achieves suppression of oestradiol to levels comparable to those observed in postmenopausal women
  2. Tamoxifen has i) an antioestrogenic effect via blockade of oestrogen receptors and ii) a local antitumour effect, independent of its effect upon oestrogen receptors Locally, tamoxifen decreases the secretion of stimulatory growth factors, such as transforming growth factor alpha (TGF α ). It also increases the secretion of an inhibitory growth factor, such as transforming growth factor (TGF β ) TGF β is also known to inhibit the growth of oestrogen-receptor-negative cells. It is believed that this is how tamoxifen can be effective in oestrogen-receptor-poor tumours Tamoxifen is thought to increase TGF β production in stromal cells in the tumour Tamoxifen may also act by other mechanisms including: i) affecting levels of sex hormones binding globulin ((SHBG) ii) preventing angiogenesis Reference Jordan VC. Tamoxifen. A guide for clinicians and patients. 1996. PPR, Inc. New York
  3. Inhibition of aromatase activity can reduce the growth-stimulatory effects of oestrogens on tumours Whilst aromatase inhibitors are known to be effective in advanced breast cancer, the role of intra-tumoural aromatase activity still remains to be clarified
