[Gastrointestinal system tumors in Italian emigrants]

In this paper we present the risk of death for stomach, colon, rectum and pancreas cancers in Italian migrants to Canada, Argentina, Australia, France and England and Wales. Estimations of relative risks (RR) in Italian migrants, in residents in Italy and in Southern Italy relative to the local born in the host country are shown. Relative risks in Italian migrants to Australia were analysed also by duration of stay in the host country. The Italian migrants' cancer profile in intermediate between the origin and the host population: a reduction of risk of death for stomach cancer and an increase of risk for colorectal cancers are the main results. The results are discussed taking into account the analysis by duration of residence and the pattern of food prevalent in the different countries considered.
