The registry of digestive tract tumours established for the department of Cote d'Or (France) was used to study the epidemiological characteristics of large bowel cancer subsites for the period 1976-1983. Age standardised incidence rates for colon cancers were 18.9/100,000 for men and 14.2/100,000 for women. The corresponding rates for rectal cancers were 18.4/100,000 and 10.2/100,000. The sex r...
