har vært økende helt siden registreringen startet tidlig på 1950-tallet. Data fra Oslo har i denne statistikken
alltid vært presentert samlet som et fylke. I denne artikkelen vises hyppighet av kolorektal kreft fordelt på
kjønn og 25 bydeler samt for fire regioner i Oslo. Utviklingen over tid fra 1956 til 1995 er vist for Oslo og Norge.
Den økende hyppighet av både tykktarm- og endetarmkreft gjennom flere tiår ser ut til å avta noe. Dette gjelder
særlig for tykktarmkreft for kvinner og endetarmkreft for menn i hele landet. Det er store variasjoner mellom
bydelene i Oslo for begge krefttyper og kjønn. Det er ingen signifikant samvariasjon på bydelsnivå mellom menn
og kvinner for hver av de to kreftformene. Det er heller ingen samvariasjon mellom sosioøkonomiske faktorer i
bydelene og hyppighet av kolorektal kreft.
Sykdommens utvikling fra adenomatøs polypp til adenocarcinom over en lang periode på 10-15 år gjør den velegnet
til screening. En planlagt screeningundersøkelse for kolorektal kreft i Telemark og Oslo er nærmere beskrevet.
Resultatene av prosjektet forventes å danne grunnlaget for en samlet nasjonal strategi mot kolorektal kreft.

Colorectal cancer – secular trend from 1956 through 1995: Results from
Telemark and Oslo and new screening for colorectal cancer prevention.

ENGLISH SUMMARY
Colorectal cancer is the most common cancer form in Norway for both genders combined. The incidence rate has
been increasing ever since the registration started in the early 1950s. Data from Oslo have always been presented
as one county in the registry. This paper presents the incidence rates for colorectal cancer split by genders and the
25 areas in Oslo. In addition, the secular trend from 1956 through 1995 is shown for both Oslo and Telemark
counties as well as for the whole country. The increasing incidence rates of both colon and rectal carcinomas have
apparently levelled off over the last 10 years. This applies particularly to colon carcinoma in women and rectal
carcinoma in men for the whole country.
There was a large variation between the 25 areas of Oslo for both cancer forms and between genders. There
was no significant correlation between men and women for either of the two cancer forms at the area level in
Oslo. Nor was there any correlation between socioeconomic factors in areas of Oslo and the incidence rate of
colorectal cancer.
The vast majority of colorectal carcinomas develop from an adenomatous polyp over a period of 10 to 15 years.
This long time span makes the disease well suited for screening. A prospective, randomized sigmoidoscopy
screening for colorectal cancer prevention in Telemark and Oslo is being planned, and the present data from these
counties serve as important background information before the screening is scheduled to start in January 1999.
