Incidence and mortality data from New South Wales (NSW) for 1973-82 were examined using log-linear regression to determine the temporal trends of cancers of the alimentary tract. There were significant increases in incidence of cancers of the colon (1.7%/year), rectum (2.6%/year), and liver (4.0%/year) and decreases for cancers of the oesophagus (-2.2%/year) and stomach (-1.4%/year). By contrast, the mortality decreased significantly for cancers of the colon (-1.0%/year) and pancreas (-1.4%/year) as well as for cancers of the oesophagus (-3.4%/year) and stomach (-4.1%/year). Cancers of the colon, rectum and oesophagus were generally less frequent, and cancer of the stomach was more frequent, among migrants to NSW than among the native-born Australians in NSW. This pattern was most evident in migrants from Greece, Italy, Yugoslavia and England and was absent in migrants from Scotland and New Zealand. When compared with the state as a whole, rural NSW had significantly lower incidences of cancers of the oesophagus, stomach, colon and rectum.
