Epithelial ovarian cancer and coffee drinking

Area of Science:

• Epidemiology
• Oncology
• Nutritional Science

Background:

• A previous study suggested a link between coffee consumption and increased ovarian cancer risk.
• Ovarian cancer remains a significant health concern with complex risk factors.

Purpose of the Study:

• To examine the association between coffee consumption and epithelial ovarian cancer risk in a US population.
• To validate or refute findings from a prior Greek case-control study.

Main Methods:

• A hospital-based case-control study design was employed.
• Data collected from 290 incident cases of epithelial ovarian cancer and 1056 controls.
• Statistical adjustments were made for known ovarian cancer risk factors.

Main Results:

• Drinking five or more cups of coffee daily showed a relative risk of 1.1 (95% CI, 0.6-2.0) compared to controls with non-malignant conditions.
• Using controls with cancer, the relative risk for high coffee consumption was 1.0 (95% CI, 0.5-1.8).
• No significant influence on risk was observed for decaffeinated coffee or tea consumption.

Conclusions:

• The study provides evidence that coffee consumption does not significantly increase ovarian cancer risk.
• If an effect exists, the association between coffee intake and ovarian cancer is likely small.
• Further research may be warranted to fully elucidate the relationship.
