The incidence of a certain type of gastric cancer has declined in the last 30 years for all age groups and races, except for whites aged 25 to 39 years of age, according to a new study.
Researchers analysed US population-based age-specific data for noncardia gastric cancer, using data from the National Cancer Institute’s Surveillance, Epidemiology, and End Results (SEER) programme, which covers approximately 26 per cent of the US population. From 1977 to 2006, there were 83,225 adults with new primary gastric cancer, including 39,003 noncardia cases.
The overall age-standardised annual incidence per 100,000 of population declined during the period from 5.9 to 4.0 in whites, from 13.7 to 9.5 in blacks, and from 17.8 to 11.7 in other races.
“The large-scale SEER database is broadly repre¬sentative of cancer incidence in the United States as a whole,” the authors concluded.
