      Risk of Gastric Cancer Unrelated to Green Tea

      WESTPORT, CT (Reuters Health) Feb 28 - Consumption
      of green tea is not associated, inversely or
      otherwise, with the risk of gastric cancer,
      according to the results of a prospective cohort
      study conducted in Japan.
      The researchers observed that the relationship was
      not substantially modified by other variables,
      including smoking, current use of alcohol, and
      daily dietary consumption. After adjustment for
      these factors, the relative risk of gastric cancer
      associated with drinking five or more cups of
      green tea per day versus less than one cup per day
      was 1.2.
      Dr. Yoshitaka Tsubono, of the Tohoku University
      Graduate School of Medicine in Sendai, and
      associates conducted their study in Miyagi
      Prefecture, a region with a high incidence of
      gastric cancer and large variation in the
      consumption of green tea. Included were 26,311
      individuals, followed between 1984 and 1992. The
      results appear in the New England Journal of
      Medicine for March 1.
      In an accompanying editorial, Dr. Takeshi Sano and
      Dr. Mitsuru Sasako of the National Cancer Center
      Hospital in Tokyo write, "The results of this
      study constitute the strongest epidemiologic
      evidence to date on the relation between the
      consumption of green tea and the risk of gastric
      They suggest that, while there is no reason to
      discontinue drinking green tea, "there should be
      no expectation that this practice will reduce the
      risk of gastric cancer."
