Etiologic heterogeneity for cervical carcinoma by histopathologic type, using comparative age-period-cohort models.
BACKGROUND Cervical carcinomas comprise two main histopathologic types, squamous cell carcinomas and adenocarcinomas. Human papillomavirus (HPV) infections are causative for both types but the respective tumors may have different carcinogenic pathways. METHODS To assess potential etiologic heterogeneity of cervical cancer by histopathologic type, we examined invasive squamous cell carcinomas ...

Age-period-cohort (APC) models are used to analyse age-specific disease or mortality rates provided for several periods in time with respect to three time scales: age, period (calendar period during which the incidence or mortality rates were observed) and cohort (time of birth).

متن کاملDescription of cervical cancer mortality in Belgium using Bayesian age-period-cohort models
Different ICD (International Classification of Diseases) were used over time for death cause certification. In the Netherlands, the proportion of not-otherwise specified uterine cancer deaths was small over large periods and therefore internal reallocation could be used to estimate the corrected rates cervical cancer mortality. In Belgium, the proportion of improperly defined uterus deaths was ...
متن کاملDeviance analysis of age-period-cohort models
Age-period-cohort models for Lexis diagrams are considered. The identification problem is addressed by reparametrizing the models in terms of freely varying parameters. The reparametrisation covers all three Lexis diagrams. A new plot of the unidentified time effects is suggested and interpreted. Deviance analysis covering a wide range of sub-models is presented. The methods are applied to Belg...
متن کاملAge-period-cohort effect on mortality from cervical cancer.
OBJECTIVE To estimate the effect of age, period and birth cohort on mortality from cancer of the cervix. METHODS Mortality data for cervical cancer in women aged over 30, between 1980 and 2009, for the municipalities of Rio de Janeiro and Sao Paulo, Southeastern Brazil,were extracted from the Mortality Information System. The estimated annual percentage change was calculated for the periods 1...
