    Medical ovariectomy in menopausal breast cancer patients with high testosterone levels : a further step toward tailored therapy

    No full text
    Five years of adjuvant therapy with anti-estrogens reduce the incidence of disease progression by about 50% in estrogen receptor-positive breast cancer patients, but late relapse can still occur after anti-estrogens have been discontinued. In these patients, excessive androgen production may account for renewed excessive estrogen formation and increased risks of late relapse. In the 50% of patients who do not benefit with anti-estrogens, the effect of therapy is limited by de novo or acquired resistance to treatment. Androgen receptor and epidermal growth factor receptor overexpression are recognized mechanisms of endocrine resistance suggesting the involvement of androgens as activators of the androgen receptor pathway and as stimulators of epidermal growth factor synthesis and function. Data from a series of prospective studies on operable breast cancer patients, showing high serum testosterone levels are associated to increased risk of recurrence, provide further support to a role for androgens in breast cancer progression. According to the above reported evidence, we proposed to counteract excessive androgen production in the adjuvant setting of estrogen receptor-positive patients and suggested selecting postmenopausal patients with elevated levels of serum testosterone, marker of ovarian hyperandrogenemia, for adjuvant treatment with a gonadotropins-releasing hormone analogue (medical oophorectomy) in addition to standard therapy with anti-estrogens. The proposed approach provides an attempt of personalized medicine that needs to be further investigated in clinical trials

    Increased androgenic activity and breast cancer risk in premenopausal women

    Blood and urine specimens from 27 premenopausal breast cancer patients and 62 healthy controls have been compared with respect to concentration of testosterone and progesterone in blood and of testosterone and androstanediol in urine, measured in the luteal phase of the menstrual cycle. There was a strong positive association between the concentration of the two androgens, either in blood or urine, and breast cancer risk. A strong association was also observed with decreasing levels of progesterone. The association was statistically significant (p for trend less than 0.01) for each hormone; the rate ratios were 10.2 for serum testosterone (highest category), 5.6 for serum progesterone (lowest category), 8.4 for urinary testosterone (highest category), and 5.2 for androstanediol (highest category). The rate ratio for women presenting both high serum testosterone and low progesterone was 21.8 (4.1 to 116.1). Considering the exposure to at least one of three androgens at the highest level and low progesterone, the rate ratio was as high as 90.2 (8.2 to 989.7). This study provides evidence for the hypothesis that increased androgenic activity is an important risk indicator for breast cancer, particularly when associated with anovulation, as indicated by low serum progesterone level
