Studying Malnutrition And Sarcopenia In Older Adults With Acute Myeloid Leukemia

This study's primary endpoint aims to measure the association of sarcopenia in study participants with their treatment-related mortality rate (how long the participant can stay alive 60 days after study treatment/registration). The incidence of sarcopenia in study participants will be measured using computed tomography-defined skeletal muscular index , hand grip strength test, and a 6-minute walk test. Treatment related mortality will be defined as the percent of patients no longer alive at 60 days after study registration.

After pre-induction assessment (including assessments for sarcopenia and malnutrition), subjects will be prospectively followed for treatment-related mortality and overall survival assessments. Overall survival will be measured from date participants start on study to either death or last follow-up in accordance with 2017 European Leukemia Net recommendations. Treatment-related mortality rates will be defined as the percent of patients no longer alive at 60 days after registration.

The incidence of malnutrition in older adults (≥60 years) with newly diagnosed AML undergoing intensive induction chemotherapy compared to the incidence of malnutrition in participants in the healthy control group. Incidence of malnutrition in both groups will be as assessed by participant questionnaires (known as subjective global assessments), blood tests , and Standardized bioelectrical impedance (BI) phase angle ( a measurement of the participant's body mass using a medical device).

Incidence of sarcopenia in both study groups will be assessed by will be assessed by using computed tomography-defined skeletal mass index at L1, hand grip strength, and a 6-minute walk test.
