New Zealand’s Young Adults At Risk For Colorectal Cancer

The incidence of colorectal cancer has, in general, decreased in New Zealand. On the other hand, incidence of rectal cancer has increased in people below 50 years of age, revealed a recent study. Among individuals aged under 50 years, the //incidence of distal colonic cancer in men increased by 14% per decade. The incidence of rectal cancer in men increased by 18% and in women by 13%.

In those aged 50-79 years, there was a reduction in incidence per decade of proximal, distal, and rectal cancers in both sexes.

In individuals aged 80 years and older, proximal cancer incidence per decade increased by 19% in women and by 25% in men; among women, the incidence of distal colonic cancer decreased by 8%, as did that of rectal cancer.

The study's investigators noted that New Zealand has among the highest rates of colorectal cancer in the world, with a median annual age-standardized rate per 10,000 of 55 for men and 44 for women.

A national colorectal cancer screening programme has been piloted, but it has yet to be introduced.

The findings are published in the British Journal of Surgery.
