Incidence of colorectal cancer in Bas-Rhin, trend and prediction in 2009

The colorectal cancer is one of the three most frequent cancers. It concern s more and more men and women and is a of heavy consequence for mortality a nd treatment. This stud attempted to predict the incidence and the number o d incident cases of colorectal cancer The analysis is a Poisson regression based on an age-period-cohort model. The predicted value of the incidence o f colon cancer, standardized on the world population (25-89 years old), is increasing with time: it is, in 2005-2009, 41.5 for 100,000 for the women a nd 104.9 for 100,000 for the men. For rectum cancer, the predicted value of incidence is, in 2005-2009, 22.9 for 100,000 for the women and 37.2 for 10 0,000 for the men. During the period 2005-2009, the number of incident case s is, for colon, 1,195 women (the mean increase, every ten years, is 31%) a nd 2,254 men (the mean increase, every ten years, is 65%). During the same period, the number of incident cases is, for rectum, 640 women (the mean in crease, ever ten years, is 24%) and 807 men (the mean increase every ten ye ars is 14%). These results are similar to those of other studies in Europe and in the World.
