Key clinical point: Regular tea consumption shows a weak inverse association with risk for gastric cancer.
Major finding: Regular vs. nonregular tea drinkers had a significantly lower risk for gastric cancer (pooled odds ratio [OR] 0.91; 95% CI 0.85-0.97). Compared with nonregular tea drinkers, there was no difference in risk for gastric cancer in regular tea drinkers who consumed 1 to <2, 2 to <3, ≥3 cups ( Ptrend = .27). A lower risk was observed in studies from China, Japan, and Iran (OR 0.62; 95% CI 0.48-0.81) and from China and Japan (OR 0.67; 95% CI 0.49-0.91).
Study details: A pooled analysis of 34 studies including 13,121 patients with gastric cancer and 31,420 control individuals from the StoP Project (a consortium of epidemiological studies on gastric cancer) dataset.
Disclosures: This study was supported by Associazione Italiana per la Ricerca sul Cancro and Italian League for the Fight Against Cancer. The authors declared no competing interests.
