The relation between coffee and alcohol intake and ovarian cancer risk was analyzed in a case-control study conducted in Italy between 1992 and 1999. Cases were 1,031 women, aged 18-79 years, with incident, histologically confirmed invasive epithelial ovarian cancer, and controls were 2,411 women, aged 17-79 years, admitted to the hospital for acute nonneoplastic non-hormone-related diseases. Coffee intake (mostly espresso and mocha) was not associated with ovarian cancer risk, with an odds ratio (OR) of 0.93 [95% confidence interval (CI) = 0.69-1.27] in drinkers of > or = 4 cups/day compared with drinkers of < 1 cup/day. No meaningful relation was observed with cappuccino (OR = 1.06, 95% CI = 0.85-1.32 for drinkers compared with nondrinkers), decaffeinated coffee (OR = 0.64, 95% CI 0.42-0.96), and tea intake (OR = 0.90, 95% CI = 0.75-1.08). Total alcohol intake was not associated with ovarian cancer risk (OR = 1.09, 95% CI = 0.76-1.57 in drinkers of > or = 36 g/day compared with never drinkers). No relationship was found with wine (OR = 1.03, 95% CI = 0.70-1.50 for > 39 g/day compared with never drinkers), beer, amari, grappa, and spirits. No significant heterogeneity was found for coffee or total alcohol intake across strata of age, education, parity, oral contraceptive use, family history of ovarian/breast cancer, body mass index, and calorie intake. This study, based on a large data set; provides no support for a causal association between invasive epithelial ovarian cancer risk and coffee and alcohol intake.

    • "Three epidemiologic studies were excluded because there was no direct assessment of tea intake [41], there was no assessment of the relationship between tea intake and EOC [42] or no confidence intervals were provided [43]. Other epidemiologic studies were excluded because green tea intake was not specifically measured [47] [48] [49] [50] [51] [52] [53] [54] [55] [56] [57] [58] [59]. One study was reported twice [18] [19], and one study was first reported in an abstract form [16] and then as a peer-reviewed article [17]. "

    ABSTRACT: This systematic review was conducted to examine the effects of green tea or green tea components on the prevention and progression of epithelial ovarian cancer. Using Medline, EMBASE and SciVerse (last researched: July 2011), we retrieved 22 articles including 5 epidemiological studies. In epithelial ovarian cancer cell lines, green tea and green tea components have been shown to downregulate the expression of proteins involved in inflammation, cell signalization, cell motility and angiogenesis. Green tea and green tea components would induce apoptosis and could potentiate the effects of cisplatin, a chemotherapeutic agent. In human observational studies, significant associations between green tea intake and both decreased ovarian cancer occurrence and better prognosis were reported. Available literature suggests potential molecular targets for green tea in ovarian cancer treatment and also provides data supporting the clinical evaluation of the role of green tea or green tea components in ovarian cancer prevention and treatment.

    • "In contrast, two case–control studies [14, 24] and one cohort study (among women with high dietary folate intake) [17] found an inverse association between wine consumption and ovarian cancer risk. However, there was no association with wine (or total alcohol) consumption in other studies [13, 18, 19]. "

    ABSTRACT: Whether alcohol consumption influences ovarian cancer risk is unclear. Therefore, we investigated the association between alcohol intake at various ages and risk of ovarian cancer. Among 90,371 eligible members of the California Teachers Study cohort who completed a baseline alcohol assessment in 1995-1996, 253 women were diagnosed with epithelial ovarian cancer by the end of 2003. Multivariate Cox proportional hazards regression analysis was performed to estimate relative risks (RRs) and 95% confidence intervals (CIs). Consumption of total alcohol, beer, or liquor in the year prior to baseline, at ages 30-35 years, or at ages 18-22 years was not associated with risk of ovarian cancer. Consumption of at least one glass per day of wine, compared to no wine, in the year before baseline was associated with increased risk of developing ovarian cancer: RR = 1.57 (95% CI 1.11-2.22), P (trend) = 0.01. The association with wine intake at baseline was particularly strong among peri-/post-menopausal women who used estrogen-only hormone therapy and women of high socioeconomic status. Alcohol intake does not appear to affect ovarian cancer risk. Constituents of wine other than alcohol or, more likely, unmeasured determinants of wine drinking were associated with increased risk of ovarian cancer.

    ABSTRACT: Laboratory data suggest that caffeine or some components of coffee may cause DNA mutations and inhibit tumor suppressor mechanisms, leading to neoplastic growth. However, coffee consumption has not been clearly implicated in the etiology of human postmenopausal ovarian cancer. This study evaluated the relationship of coffee and caffeine intake with risk of epithelial ovarian cancer in a prospective cohort study of 29,060 postmenopausal women. The participants completed a mailed questionnaire that assessed diet and health history and were followed for ovarian cancer incidence from 1986 to 2004. Age-adjusted and multivariate-adjusted hazard ratios were calculated for four exposure variables: caffeinated coffee, decaffeinated coffee, total coffee, and total caffeine to assess whether or not coffee or caffeine influences the risk of ovarian cancer. An increased risk was observed in the multivariate model for women who reported drinking five or more cups/day of caffeinated coffee compared to women who reported drinking none (HR=1.81, 95% CI: 1.10–2.95). Decaffeinated coffee, total coffee, and caffeine were not statistically significantly associated with ovarian cancer incidence. Our results suggest that a component of coffee other than caffeine, or in combination with caffeine, may be associated with increased risk of ovarian cancer in postmenopausal women who drink five or more cups of coffee a day.
