Trends in age-standardized incidence, mortality, complement to mortality-to-incidence ratio (1-M/I ratio), and net survival (NS) in England, 1981 to 2009. Four cancers for which the 1-M/I ratio for 2009 differed by 15% or more from 5-year NS for patients diagnosed in 2009: (A) stomach (men), (B) cervix, (C), colon (women), and (D) rectum (men). Solid blue lines, 1-, 5-, and 10-year NS; dashed brown line, 1-M/I; dashed teal line, incidence rate; solid brown line, mortality rate.
