RESUMEN
Daunorubicin and Cytarabine (DA; 3 + 7) has been the standard frontline Acute Myeloid Leukemia (AML) induction regimen resulting in Complete Remission (CR) rates of 50-70%. It is associated with induction mortality of 15-30%. We report a comparative analysis of DA versus fludarabine, cytarabine, G-CSF (FLAG) + /- Venetoclax in resource constrained settings. We conducted a single center, retrospective analysis of 37 treatment naïve fit AML patients from May 2021 to December 2022 who received either standard DA regimen (Group 1) or FLAG + /- Venetoclax (Group 2). The median patient age was 36.6 years in DA arm (n = 18) as compared to 40.1 years in FLAG arm (n = 19). CR rates at day 28 were 55.5% in group 1 and 89.4% in group 2 (odds ratio [OR], 7.20; 95% confidence interval [CI], 1.274 -40.678; P = 0.012). Patients in FLAG based therapy arm had shorter duration of neutropenia (P = 0.003), fewer episodes of grade 3 febrile neutropenia (P = 0.0228), shorter duration of antibiotic therapy (P = 0.03), lesser need of 3rd line antibiotic therapy (P = 0.0228). Mortality rates were 16.6% (n = 3) in (group 1) and 0% (n = 0) in (group 2) (p = 0.105). Our analysis supports that FLAG based induction regimen is an effective and well-tolerated therapy in treatment naïve fit AML patients.
