Stratification Using ECOG, ADL and HCT-CI Scales, but Not CGA Enables Identifying Elderly AML Patients Fit for Intensive Chemotherapy - a Multicenter Study from Polish Adult Leukemia Group

Introduction: A key part of decision-making in older AML patients is an insightful clinical assessment before qualification for treatment with intensive chemotherapy (IC). It was demonstrated that among the patients initially deemed “fit” for IC, there are vulnerable patients who experience greater treatment toxicity and have poorer outcomes. Comprehensive geriatric assessment (CGA) is a well-recognized tool for identifying such patients. However, due to its time-consuming nature, it is not commonly used. A number of other prognostic models exist, but none of them enable fast and optimal identification of patients eligible for IC. Aim: In this prospective observational study our group aimed to I) assess clinical outcomes of elderly AML patients who were stratified by Eastern Cooperative Oncology Group Performance Status (ECOG PS), Hematopoietic Cell Transplantation Comorbidity Index (HCT-CI), Activity of Daily Living (ADL) scales and received IC and II) evaluate the predictive and prognostic value of CGA components. Material and methods: AML patients aged between 60 and 75 were considered fit for IC if they met all 3 stratification criteria: ECOG PS
