Primary hepatocellular carcinoma in Australia, 1978-1997: increasing incidence and mortality.
OBJECTIVE
To describe trends in primary hepatocellular carcinoma (HCC) incidence and mortality in Australia between 1978 and 1997, and to delineate the effects of hepatitis B virus (HBV) and hepatitis C virus (HCV) infection by examining cases of HCC in Australian-born and overseas-born people separately.


METHODS
Retrospective analysis of national incidence and mortality data in which the underlying cause was coded as HCC (International classification of diseases, ninth revision [ICD-9] code 155.0).


METHODS
Changes in age-standardised HCC incidence rates in men and women between 1983 and 1996; age-standardised HCC death rates in Australian-born and overseas-born men and women between 1978 and 1997.


RESULTS
Age-standardised incidence rates increased in men and women (from 2.06 and 0.57 per 100,000 respectively in 1983-1985 to 3.97 and 0.99 respectively in 1995-1996). Age-standardised death rates increased in Australian-born and overseas-born men and overseas-born women (from 1.43, 2.35 and 0.62 respectively per 100,000 in 1978-1982 to 2.50, 4.41 and 1.36 respectively in 1993-1997). However, death rates in Australian-born women did not increase (0.58 per 100,000 in 1978-1982 and 0.63 in 1993-1997).


CONCLUSIONS
HCC incidence and death rates in Australia have increased over the past two decades, except in Australian-born women. A likely explanation for at least a portion of this increase is increased prevalences of HBV and HCV infection in Australia.
