The changing incidence of cancer in adults in New South Wales.
Data from the New South Wales (NSW) Central Cancer Registry comprising all new cases of cancer registered in persons aged 15 years and over for the 10-year period 1973 to 1982 were examined using log-linear regression to determine whether the incidence of cancer had been changing in NSW. Allowing for the altered age and sex structure of the population over this period, the annual incidence rate for all sites combined increased significantly by 1.7% in men and 1.0% in women. Cancers which had increased at a rate significantly greater than that for all sites combined were those of unknown primary site (8.7% per year), lung (in women only, 5.6%), kidney (4.5%), bladder (2.7%) and rectum (2.6%) and lymphomas (2.6%). Other cancers which showed a significantly increased incidence rate per se were testis (3.5%), larynx (3.2%), prostate (2.1%), colon (1.7%), brain (1.6%), leukaemias (1.3%) and lung (in men only, 0.7%). Cancers which had decreased significantly in incidence were those of oesophagus (-2.2%), cervix uteri (-2.0%) and stomach (-1.4%). No significant change in incidence over the 10 years had occurred for cancers of the corpus uteri, breast, ovary or pancreas.
