摘要

To estimate the population attributable fractions (PAFs), de Mattel and colleagues used data on cancer incidence from the GLOBOCAN project, along with the most recent epidemiological evidence on the causal effect of each infection on cancer and the most reliable data on prevalence of infection among cases. For HBV and HCV, where reliable data on prevalence were not available for many countries, logistic regression models were fitted using data on cancer incidence to estimate prevalence of infection in cancer cases. This method might have led to overestimation of prevalence when cross-country variations are due to other causes of cancer (eg, alcohol use for liver cancer). Future investigations might benefit from collating all available evidence on exposure to infection, including cancer registry data and population surveys.
