Data source: Surveillance, Epidemiology, and End Results. Of the cancer sites considered, cigarette smoking has the strongest impact on lung cancer. Figure 1 shows trends in invasive lung cancer prevalence rates per 100,000 for white men in Utah and SEER (with Utah removed) by year. Because SEER began collecting and reporting data in 1973, prevalence trends composed of cases diagnosed from 0-1 year previously are plotted from 1974 through 1995, from 0-5 years previously are plotted from 1978 through 1995, and so on. Lung cancer prevalence rates in Utah are distinct from those in the United States in trend and magnitude. They remain comparatively flat and the magnitude in prevalence rates based on 0-20 years of diagnosed cases remains much lower than the United States prevalence rates. Figure 2 shows trends in age-specific invasive lung cancer prevalence rates per 100,000 for white men in Utah and SEER (with Utah removed) among cases 0-5 years from diagnosis. The age categories reflect ages at the time of diagnosis. For the United States, the initial increase in overall trends is seen in each age group. However, the age group 50-59 is distinct in that a steady decline in rates begins in 1986. This decline is not observed until 1994-1995 for the older three age categories. For Utah, the relatively small increase in overall trend in the 1980s is largely explained by cases 60-69 and 70-79. Unlike the United States where the magnitude of the rates for each age group is distinct, Utah lung cancer prevalence rates are very similar between age groups 50-59 and 80+ and between age groups 60-69 and 70-79. 13 |
