11q23 translocation in children with acute lymphocytic leukemia following primary response to chemotherapy: prognostic significance and diagnostic accuracy

Background: Cytogenetic abnormalities in leukemia cells have strong prognostic values for different clinical subgroups, clinical features, and therapeutic outcomes. Patients and Methods: This study was conducted on 100 children with acute lymphocytic leukemia referred to Ahvaz Shafa Hospital during 2012–2017. The patients were diagnosed by a specialist through examination of morphology and flow cytometry, testing bone marrow specimen on the 7^th day of treatment, and a karyotype and cytogenetic test are performed. Results: There was no relationship between the t(11q23) and gender nor age of children. Besides, the mean white blood cell (WBC) counts in patients who were negative for 11q23 and those positive revealed a statistically significant relationship between WBC count and 11q23 (P = 0.022). Conclusion: A significant association between the 11q23 translocation and primary response to chemotherapy is existed. Diagnostic accuracy of these tests for detecting t(11q23) is generally high, as well as sensitivity and specificity are optimal for all anomalies.
