causes as censoring events, the concept of relative survival was developed by comparing the observed survival probability of a group of cancer patients with the survival of a âsimilarâ cancer-free group. Relative survival is defined as the ratio of the observed survival (all cause survival) of a cohort of cancer patients to the expected survival of a comparable set of cancer free individuals.
The relative survival rate measures the survival of patients with brain cancer in comparison to the general population to estimate the effect of cancer. The overall 5-year relative brain cancer survival rate for 1995-2001 was 33.3 percent.The 5-year relative survival rates for brain cancer by race and sex were as follows: 1  32.1 percent for Caucasian men. 2  33.5 percent for Caucasian women. 3  37.7 percent for African-American men. 4  37.5 percent for African-American women.he overall 5-year relative brain cancer survival rate for 1995-2001 was 33.3 percent.
