Cruciferous vegetables and esophageal cancer.

Esophageal cancer risk: Data about the relation with esophageal cancer risk was provided by 3 cohorts, including a total of 493 cases. A significant protective effect was found in one cohort (8), and a nonsignificant protective effect was found in another cohort against EAC, but not ESCC risk (7).

Esophageal cancer mortality: No data was found.

Conclusion: Protective effects were found in 2 cohorts, but these were significant only once. Inconclusive evidence was found for an association between cruciferous vegetables and esophageal cancer risk.
