Clinical and Cytogenetic Characteristics of Children With Leukemia 20-Year Retrospective Study

Acute leukemias are the most common malignant diseases in childhood. The aims of this retrospective cohort study were to investigate the frequency of cytogenetic abnormalities in acute pediatric leukemia ; the correlation between cytogenetic abnormalities and 5-year survival ; and the correlation between cytogenetic abnormalities and clinical and laboratory features. We included 105 patients ; acute lymphoblastic leukemia (ALL) had 80.9% patients, B-cell lineage ALL (B-ALL) 84.7% of them, and T- cell lineage (T-ALL) 15.3%. The overall 5-year survival for B-ALL was 85.9% and for T-ALL was 84.6%. The most common cytogenetic abnormalities in patients with B-ALL were t(12 ; 21)(p13.2 ; q22.1) ; ETV6-RUNX1 with 22.2% and hyperdiploidy with 19.4%. Our survival analysis showed that t(12 ; 21)(p13.2 ; q22.1) ; ETV6- RUNX1 and t(1 ; 19) (q23 ; p13.3) ; TCF3-PBX1 had the best 5-year survival with 100% of patients surviving, whereas t(v ; 11q23.3) ; KMT2A rearranged had the worst 5- year survival of just 33.3% of patients surviving after 5 years. We found no difference in 5-year survival in B-ALL when comparing clinical features. Acute myelogenous leukemia had 20 patients with 70.6% 5-year survival. The most common cytogenetic abnormality in acute myelogenous leukemia was t(8 ; 21) (q21 ; q22.1) ; RUNX1-RUNX1T1 (20%). In conclusion, this study showed the correlation of different cytogenetic abnormalities with 5-year survival in B-ALL patients. Such correlation was not found when comparing clinical features and 5-year survival of patients with B-ALL. This emphasized the significance of cytogenetic analysis in pediatric leukemia.
