Assessing changes in the impact of cancer on population survival without considering cause of death.
We have previously argued against the calculation of cancer-specific death rates as philosophically undefined and biased.
Deaths attributed to cancer during a particular year occur in patients diagnosed during an unknown distribution of past times, so cancer-specific death rates cannot be used to assess changes in the impact of cancer on survival of the population at specific periods of diagnosis.
Our goal was to develop and analyze three measures of the impact of cancer on population survival that do not use the attributed cause of death : 1) the age-adjusted proportion of the population diagnosed with cancer in a particular year and projected to be dead of any cause by a particular age ; 2) the same measure corrected for population mortality ; and 3) the expected years of life lost to a 20-year-old individual because of the possibility of a diagnosis of cancer.
Data on all adults diagnosed with any cancer during the period from January 1973 through December 1990 were obtained from the Surveillance, Epidemiology, and End Results (SEER) Program of the National Cancer Institute.
The measures were calculated separately for various combined sex and race groups.
Three 2-year diagnosis periods spaced 5 years apart were considered : 1975-1976,1980-1981, and 1985-1986. (...)
