"In daily clinical practice, 2022 ELN guidelines were used to predict response to conventional treatment and to guide the need for allogenic stem cell transplantation. But, the team has to underline that ELN guidelines are mainly reflective of relatively young Caucasian patients. Few studies have compared 2017 and 2022 ELN in ethnicity cohorts to evaluate the potential prognostic value of this new criteria in these types of population. For example, with the 2022 ELN guidelines, the disease-free surviva) and the overall survival of African American \< 60 y.o were not statistically different between intermediate and adverse groups (p=0.30, p=0,46). There were not a significant difference between favorable and intermediate groups in DFS (p=0.42, p=0.42) respectively in African American and Hispanic patients or in OS (p=0.67) in Hispanic patients. Is the 2022 ELN applicable to all ethnic subgroups? To date, no studies have examined and validated its applicability in Middle Eastern or North Coast of Africa (MENAFC) patients."

"Number of chemotherapy-related adverse events. Adverse events (AEs) were evaluated according to Common Terminology Criteria for Adverse Events classification: CTCAE (Version 4.0). Grade 1 = Mild - transient or mild discomfort; no limitation in activity; no medical intervention/therapy required * Grade 2 = Moderate - mild to moderate limitation in activity, some assistance may be needed; no or minimal medical intervention/therapy required * Grade 3 = Severe - marked limitation in activity, some assistance usually required; medical intervention/therapy required, hospitalization is possible * Grade 4 = Life threatening - extreme limitation in activity, significant assistance required; significant medical intervention/therapy required, hospitalization or hospice care probable * Grade 5 = Death "
