CLL Epidemiology

  • Estimated new cases of CLL (male and female) in 2018 = 20,9401,2
  • It is estimated that in 2018, CLL will account for 34.73% of all leukemia diagnoses2
  • Estimated cancer deaths due to CLL in 2018 = 4,5101,2
  • From 2008 – 2014, the percentage of patients with CLL surviving 5 years = 84.2%1
  • Median age at diagnosis = 70 years of age1
  • CLL is more common in adult Caucasian men – the number of new cases in Caucasian men from 2011-2015 was 6.9 per 100,000 persons while the overall number of new CLL cases during the same time frame was 4.7 per 100,000 persons1
  • Based on data from 2011-2015, the number of deaths from CLL was 1.3 per 10,000 men and women per year
