title: Differential survival improvement for patients 20-29 years of age with acute lymphoblastic leukemia.
abstract: OBJECTIVE
  To compare improvement in survival from 1986 to 2009 for acute lymphoblastic leukemia (ALL) patients 1-14, 15-19 and 20-29 years in Ontario and United States.
  
  
  METHODS
  This population-based analysis used data from Ontario Cancer Registry (OCR) and Surveillance Epidemiology and End Results (SEER).
  
  
  RESULTS
  In OCR, there was steady improvement in survival by period of diagnosis in all three age groups. In SEER, there was no improvement in survival for patients aged 20-29 years.
  
  
  CONCLUSIONS
  Survival in Ontario and the United States has improved for patients with ALL aged 1-19 years. However, survival has improved among patients aged 20-29 years only in Ontario.
