  • Relative cancer survival is defined as the ratio of the observed all-cause survival in a group of individuals with cancer to the expected all-cause survival of a similar group of individuals who do not have cancer. (cdc.gov)
  • Thus, the relative cancer survival is calculated as the observed all-cause survival in a group of individuals with cancer divided by the expected all-cause survival of the general population. (cdc.gov)
  • Observed all-cause survival by sex, race, and ethnicity (all races, non-Hispanic White, non-Hispanic Black, non-Hispanic American Indian and Alaska Native, non-Hispanic Asian and Pacific Islander, and Hispanic) for individuals with any cancer and for individuals with 25 common cancer sites was then calculated using the actuarial life table method.
