| Abstract |
The objective of this work was to apply the two-stage clonal expansion model, with the intention to expand the literature on epidemiological applications of the model and demonstrate the feasibility of incorporating biologically based modelling methods into the widely used retrospective cohort study. The two-stage clonal expansion model was fitted to three occupational cohorts: textile workers exposed to asbestos and followed for lung cancer mortality; diatomaceous earth workers exposed to silica and also followed for lung cancer mortality; automotive manufacturing workers exposed to straight metalworking fluid (MWF) and followed for larynx cancer incidence. The model allowed estimating exposure effects in three stages: cancer initiation (early effects), promotion or malignant transformation (late effects). The findings for asbestos and silica were essentially confirmatory, supporting evidence for their early effects on lung cancer from a large body of literature. The effect of straight MWF on laryngeal cancer was less clear. |
