A search using several electronic bibliographic databases was performed for relevant epidemiological literature between 1966 and 2006. A total of 13 unique studies including over 5,000 cases were found. Categorical and third order polynomial (cubic) regression models were fitted to estimate the temporal relationship between years of drinking cessation and risk of cancer. The risk of esophageal cancer significantly increased within the first 2 yr following cessation [odds ratios (ORs)0-2 yr: 2.50, 95% confidence intervals (CI): 2.23-2.80], then decreased rapidly and significantly after longer periods of abstention (OR15+ yr: 0.37, 95% CI: 0.33-0.41).
