Age-specific trends in incidence of noncardia gastric cancer in US adults

Descriptive study with age-period-cohort analysis of cancer registration data from the National Cancer Institute's surveillance, epidemiology, and end results program were utilized to examine the effects of age at diagnosis on noncardia gastric cancer incidence trends in the United States. The data obtained from 1977 through 2006 which showed the declined incidence rate for noncardia gastric cancer among all race and age groups except for whites aged 25 to 39 years warranted further surveillance and analytical studies to identify the risk factors that might explain the observed unfavorable trends.
