Chronic lymphocytic leukemia (CLL) is a disease characterized by an increasing incidence with age reaching 35/100,000 in patients over 85 years. Elderly CLL patients carry several challenges, which have to be considered particularly in advanced stages including a higher risk of infections and individual differences in comorbidities and geriatric syndromes. Although no specific tool for geriatric evaluation in CLL has been developed so far, several of them (e.g. CIRS or Charlson-Score) have been tested in CLL patients.
