Male lung cancer average person-years of life lost (PYLL) by year, and its changes and decomposition over 5-year intervals showing large reductions in male lung cancer burden as a result of declines in lung cancer mortality rates since 1985. (A) Male lung cancer PYLL by year. (B) Decomposition of male lung cancer PYLL over 5-year intervals. Gold bars indicate the change in PYLL, gray bars indicate the change in PYLL as a result of changes in lung cancer mortality rates, and blue bars indicate the change in PYLL as a result of changes in other-cause mortality rates. We do not report any sampling uncertainty in PYLL or in the decomposition of PYLL because our calculations use registry and vital statistics data that fully capture the mortality experience of defined populations. Note that PYLL, the average years of life lost per US adult, equals the gain in life expectancy in the absence of deaths resulting from cancer.
