Manton K G (Duke University, Center for Demographic Studies, Box 4732, Duke Station, Durham, North Carolina 27706, USA) and Stallard E. A cohort analysis of U.S. stomach cancer mortality 19501977 International Journal of Epidemiology 1982, 11: 4961.
Models of human carcinogenesis, such as the multi-stage model of Armitage and Doll, are designed to explain the age increase in the incidence of cancers in individuals. As a consequence, analyses of population level age-specific death rates via such models are appropriately applied to cohort data where such data are available. In this study a multi-stage model is applied to cohort data for stomach cancer death rates in the U.S. population for nine distinct cohorts observed over a recent 28-year period (19501977). The multi-stage model parameters obtained from the analysis of the cohort data show significant differences from the parameters obtained from analyses of cross-sectional mortality data under the assumption of no cohort differences in age-specific stomach cancer death rates.
