Treatment ofhematological malignancy is mainly chemotherapy and furthermore it is necessary to keep its dose intensity. In the elderly, adverse events may be strong due to deterioration oforgan function, comorbidity, etc., and it is difficult for individual differences to decide chemotherapy regimen and dose. Geriatric assessment(GA)used in the field of geriatric medicine is reported to be useful for risk assessment of chemotherapy. The usefulness of GA is also shown in hematological malignancy.
