title: Relative survival analysis using the Centers for Disease Control and Prevention's National Program of Cancer Registries Surveillance System Data, 2000-2007.
abstract: BACKGROUND
  Cancer survival rates are important in evaluating cancer care, identifying disease patterns, and estimating the probability of death due to cancer. To date, survival rates have been calculated using other data sets with limited population coverage that may not be able to fully identify differences by treatment, geographic region, and racial or ethnic group. Data from the Centers for Disease Control and Prevention's (CDC's) National Program of Cancer Registries (NPCR) have not been used previously to calculate relative survival rates within the United States.
  
  
  METHODS
  Data from CDC's November 2011 submission for 21 state population-based central cancer registries, representing 50 percent of the US population, were included in this analysis. This paper presents relative survival rates for diagnosis years 2000-2007 with follow-up through 2008.
  
  
  RESULTS
  The relative survival rate for all cancers and races combined was 65.0 percent (65.3 percent for male and 64.8 percent for female patients). Black patients had a lower relative survival rate than white patients, except for lung and bronchus. For all cancers, the under 45 age groups had the highest relative survival rates, except for black males.
  
  
  CONCLUSIONS
  For all cancer primary sites combined for 2000-2007, the CDC NPCR 5-year relative survival rate is comparable to that reported by the National Cancer Institute and the Canadian Cancer Registry. This analysis presents, for the first time, relative survival rates for half of the total US population and demonstrates that reliable survival rates can be calculated using CDC's NPCR data now and in the future.
