Endometrial hyperplasia is a precursor lesion of endometrial carcinoma. Clinical studies of endometrial hyperplasia have shown that levonorgestrel (LNG) is more therapeutically effective than medroxyprogesterone acetate (MPA). The present pharmacological in vitro study was performed to compare progestin effects on

The development of female steroid hormone-related neoplasms such as gynaecologic and mammary cancers is influenced by hormones administered exogenously. Hormonal contraceptives and hormone replacement therapy both affect the risk of developing cancers in the endometrium, cervix, ovarium, and mammary glands.

Patients with endometrial hyperplasia representing preliminary stages of endometrial cancer have shown to respond to therapy in 100% of the cases when treated with levonorgestrel-impregnated intrauterine device. Anti-proliferative effect has also been reported after application of an anti-progestin impregnated intrauterine

About 50% of the cases with invasive carcinoma of the uterine cervix occurs before menopause. Cyclic changes of sex steroids may therefore interfere with the ratio between extracellular levels of cGMP and cAMP (cGMP(ex)/cAMP(ex)). This ratio has been proposed as
