Treating octogenarian and nonagenarian acute myeloid leukemia patients--predictive prognostic models.

ABSTRACT: Treating the octogenarian and nonagenarian patients who have acute myeloid leukemia (AML) with intensive chemotherapy is controversial. Several models to predict outcome were proposed, including the use of a comorbidity index. However, it is unclear whether the Charlson comorbidity index (CCI) or the hematopoietic cell transplant comorbidity index (HCTCI) is more sensitive.The authors analyzed their experience with 92 patients aged >or=80 years who had AML. Patients' pretreatment characteristics and their treatment outcomes were recorded.All patients were offered intensive treatment; 59 patients (64%) were treated intensively with a variety of regimens, whereas 33 patients (36%) elected to receive supportive care. The CCI and the HCTCI had similar predictive ability for outcome in both groups. A multivariate analyses of prognostic factors identified near-normal albumin (48% of patients; 1-year survival rate, >27%) as a favorable factor for the whole cohort, age <83 years (47% of patients; 1-year survival rate, >25%) and nonmonocytic morphology (75% of patients; 1-year survival rate, >26%) as favorable factors for the intensively treated cohort, and bone marrow blasts <46% (50% of patients; 1-year survival rate, >19%) as a favorable factor for patients who received supportive care.This retrospective analysis was developed to assist in treatment decisions for octogenarian and nonagenarian patients with AML. The findings will need validation in a prospective study.
