women (Table 3). Expanding those age limits from 50 to 75 would correspond
to more than half of the CRC cases in Belgium.
Age-specific incidence rate is the number of new cases per year in a specific 5year
age group per 100.000 inhabitants in the same age group. Age-specific
incidence rates by gender for colorectal cancer in Flanders, years 2000 - 2001,
are presented in Figure 3. Incidence data were calculated on the basis of the
annual absolute incidence and age-specific population data from the National
Institute of Statistics (NIS).

The Flemish registration also provides data on primary tumor localisations, and,
especially in view of the different options for screening, this is important to
consider, since not all techniques are equally able to detect abnormalities in all
parts of the colon.
Distribution by localisation in Flanders 2000 - 2001 is shown in Figure 4.
However, it should be recognised that the exact primary localisation was
unknown in 17% (colon, not otherwise specified).
