title: [Trends of cancer mortality rates in children and adolescents by level of marginalization in Mexico (1990-2009)].
abstract: OBJECTIVE
  To determine childhood and adolescent cancer mortality by the level of marginalization in Mexico.
  
  
  METHODS
  We used 1990-2009 death certificates estimating age-standardized rates. We calculated the Average Annual Percent Change (AAPC) using the Joinpoint Regression program available at the National Cancer Institute to assess tendency.
  
  
  RESULTS
  Cancer mortality rates increased. AAPC were 0.87% male and 0.96% female children, and for adolescents were: males 1.22% and females 0.63%. The neoplasm pattern in infants was leukemia -central nervous system- lymphomas; and in adolescents it was leukemia -bone and articulation- lymphomas. The increase in cancer mortality corresponded to the high and highest marginated areas of each state.
  
  
  CONCLUSIONS
  The increase in highly marginated areas may be partly explained by well-documented local registration of deaths. Further studies focusing on survival are required in order to better assess the effectiveness of cancer detection and medical treatment in our country.
