FRIDAY, Aug. 18 (HealthDay News) -- Drinking carbonated soft drinks is not associated with esophageal adenocarcinoma, according to the results of a population-based study published in the Aug. 16 issue of the Journal of the National Cancer Institute.
Because carbonated soft drinks can stimulate acid secretion and trigger symptomatic reflux, it has been suggested that increased consumption may be the cause for a rise in esophageal adenocarcinoma. Jesper Lagergren, M.D., and colleagues from Karolinska University Hospital in Stockholm, Sweden, analyzed data from a nationwide Swedish case-control study to examine the association between the two.
After interviewing and reviewing data from 189 patients with esophageal adenocarcinoma, 262 patients with cardia adenocarcinoma and 820 controls, the investigators found no link between carbonated soft drink consumption and cancer. In fact, those who consumed a high amount of soft drinks -- six or more per week -- had a slightly reduced risk for adenocarcinoma although the association was not statistically significant.
"This study gives no support for the hypothesis that the use of carbonated soft drinks contributes to the increasing incidence of this cancer," the authors conclude.
