Cancer mortality in Italian migrants to Canada.
The present study reports on the analysis of cancer mortality in Italian first-generation migrants resident in Canada, deceased in the period between 1964-1985 (5,801 males: 3,267 females). Mortality in migrants is compared to that of the host population as well as to that in the migrants' country of origin. This is carried out both on a national level (Italy), and on a regional level with those regions that have made the greatest contribution to the Italian migratory flow (Southern Italy). Compared with the Canada-born population, significantly higher risks were evident for nasopharynx, stomach, liver and gallbladder tumors in migrants. Lower risks were observed for the oral cavity, esophagus, colon, rectum, pancreas (females), larynx, lung, melanoma, breast, ovary, prostate, bladder (females), and non-Hodgkin's lymphoma in migrants. This is consistent with that evidenced in the comparison between Italy and Canada. The data are discussed in relation to the results of other studies on Italian migrants and the prevalence of main risk factors.
