Abstract
The relationship between alcohol drinking (mainly wine) and risk of colon and rectal cancer was considered in a case‐control study conducted between 1991 and 1996 in six Italian centers. Cases were 1,225 patients 51.82 g ethanol/day) were 1.01 for colon cancer and 0.90 for rectal cancer, and those for ex‐drinkers were 1.20 and 1.07, respectively. The OR for wine drinkers in the highest quartile of intake were 1.07 for colon cancer and 0.97 for rectal cancer. No association was found with duration of the habit, time since starting, or age at starting. Among ex‐drinkers, no association appeared with time since stopping. No significant heterogeneity was found across strata of age at diagnosis, sex, education, smoking status, physical activity, family history of colorectal cancer, β‐carotene, vitamin C, coffee, total fiber and folate intake, and number of meals per day. No significant association appeared for various intestinal subsites.
