Abstract

Introduction: Acute lymphoblastic leukemia (ALL), a hematopoietic cancer of T or B lymphoblasts, is the most prevalent cancer in children. Ongoing research aims to better understand the factors contributing to ALL and create more successful treatment options. Therefore, the current study presented cytogenetic, genetic, and hematologic features from 318 ALL patients under eighteen years of age who were referred to Ali Asghar Hospital of Tehran, Iran, from 2013 to 2023. Methods: This study was designed as a retrospective cross-sectional analysis, focusing on 318 children in Tehran, Iran, who had been newly diagnosed with ALL. All data were extracted from the patient case files that included additional information, such as clinical data, and demographic information. The Flow cytometry technique was employed to perform immunophenotyping for various markers. Moreover, the standardized protocol was carried out for conventional cytogenetic analysis. Results: Out of 318, 179 (56.3%) and 139 (43.7%) were males and females, respectively. The most common subtype of ALL was Common B Cell ALL, accounting for 182 cases (57.23%), followed by Pre B cell ALL with 74 cases (23.27%) and T cell ALL with 27 cases (8.49%). Out of 222 patients, 17 (7.7%) had genetic abnormalities, with the highest incidence of abnormalities being associated with Runx 1 (four cases). Additionally, out of 228 patients, 143 (62.7%) were identified as having cytogenetic abnormalities, with the most prevalent abnormalities being hyperdiploidy (54 cases) and t (12;21) (28 cases). Conclusion: Our findings showed that some cytogenetic abnormalities, such as t (9;22) and hyperdiploidy, were consistent with previous studies. These results offer valuable foundational insights that can help direct future research on ALL patients and inform potential treatment strategies. © 2025 Elsevier B.V., All rights reserved.
