At least 90% of human ovarian cancers may originate in the OSE. Most studies indicate that EOC is oestrogen responsive. Paradoxically, ovarian cancer generally occurs after the menopause, so the question arises if oestrogen is involved, where does it come from? We hypothesise that the high circulating concentrations of conjugated (inactive) oestrogens in post-menopausal women are substrates for formation of active oestrogen in the OSE through the hydrolytic enzyme activity of ...
