Abstract

Overall, our findings provide some support for the hypothesis that tea consumption reduces the risk of ovarian cancer.

Green tea for ovarian cancer prevention and treatment: A systematic review of the in vitro, in vivo and epidemiological studies

“…Four case-control studies measuring the effects of green tea on EOC incidence were reported [44][45][46]61].…”

“…Consumption of at least one cup of tea daily was inversely associated with the occurrence of EOC (OR: 0. 46 These four observational studies [44][45][46]61] contain several limitations. It is first difficult to compare them because different definitions of tea intake have been used throughout the studies (e.g.…”

“…Also, the total amount of catechins in green tea will vary according to the type of green tea, and then according to the amount of leaves used and to the duration of infusion, making it even more difficult to compare real catechin intake [73,74]. Green tea intake as reported in the four studies varied widely between the regions of the world [44][45][46]61]. Most women included in the Chinese study were tea drinker but most women included in the Western/ Australian studies were not.…”

Cancer Preventive Effects of Green Tea Polyphenols

“…The same authors conducted a meta-analysis and found a non-significant inverse association between green tea intake of $ 1 cup/day and ovarian cancer (OR 5 0.58). 61 The protective effect of green tea intake against ovarian cancer may be stronger in post-diagnosed women. Zhang et al 62 conducted a prospective cohort, following postdiagnosed women for at least 3 years.…”

The qualitative analysis of the green tea extract using ESI-MS method

“…in the initiation phase and the promotion phase. The consumption of green tea reduces the risk of development of several cancers including colon, breast, ovarian, prostate and lung cancer [14][15][16][17][18][19][20].…”
