New Zealand has among the highest rates of colorectal cancer in the world and is an unscreened population. The aim of this study was to determine the trends in incidence and tumour location in the New Zealand population before the introduction of national colorectal cancer screening.
Data were obtained from the national cancer registry and linked to population data from 1995 to 2012. Incidence rates for colorectal cancer by sex, age (less than 50 years, 50–79 years, 80 years or more) and location (proximal colon, distal colon and rectum) were assessed by linear regression.
Among patients aged under 50 years, the incidence of distal colonic cancer in men increased by 14 per cent per decade (incidence rate ratio (
The increasing incidence of rectal cancer among younger patients needs to be considered when implementing screening strategies.Full text
