Endocrine status in stage II vs. advanced premenopausal and postmenopausal breast cancer patients

Abstract

Circulating preoperative levels of DHEA-S, androstenedione and SHBG were measured in 40 premenopausal and 49 postmenopausal breast cancer patients, and in 30 and 15 age-matched healthy controls, respectively. Moreover, the levels of LH, FSH, prolactin, estradiol, progesterone, testosterone, DHEA-S, androstenedione and SHBG of Stage II breast cancer patients were compared with advanced patients and also with controls. In premenopausal patients the levels of steroid hormones were significantly low whereas those of peptide hormones were significantly high. On the contrary, in postmenopausal patients, except DHEA-S, all other hormones were significantly elevated in comparison with controls. In premenopausal patients, DHEA-S, androstenedione, estradiol, progesterone, and testosterone decreased as stage advanced with concomitant increase of SHBG, LH, FSH and prolactin when compared with hormone levels of Stage II patients. In postmenopausal advanced breast cancer patients, when compared with Stage II patients, the levels of SHBG, LH, FSH, and prolactin increased significantly, while DHEA-S, androstenedione, estradiol, and progesterone decreased as stage advanced.
