Abstract:

Objective To investigate the correlation between baseline data, early treatment response and prognosis in children with acute lymphoblastic leukemia (ALL). Methods Ninety-two children with ALL were divided into the endpoint event group (19 cases) and the event-free survival group (73 cases) according to whether there was an endpoint event (recurrence or death). The age and gender at initial diagnosis were recorded. Initial white blood cell count (WBC), platelet count (PLT), immunophenotype, chromosome karyotype, fusion gene, prednisone test, bone marrow remission status on the 15th day of induction chemotherapy and minimal residual disease (MRD) on the 15th, 33rd and 55th day of induction chemotherapy were detected. The correlation between the above baseline data and early treatment response and the occurrence of endpoint event in children with ALL was analyzed. Logistic regression was used to analyze influencing factors of endpoint events in children with ALL. Receiver operating characteristic (ROC) curve was plotted to evaluate the predictive value of baseline data and early treatment response to endpoint events in children with ALL. Results The proportion of WBC ≥100×109/L at first diagnosis, prednisone poor reaction and positive MRD on the 33rd day of induction chemotherapy were higher in the endpoint event group than those in the event-free survival group (P < 0.05), and there were no significance differences in remaining indicators (P > 0.05). Logistic regression analysis showed that prednisone poor reaction and positive MRD on the 33rd day of induction chemotherapy were risk factors for endpoint event in children with ALL (P < 0.05), and the combined value of the two indicators was better than that of a single indicator in predicting endpoint events in children with ALL. Conclusion Prednisone poor reaction and positive MRD on the 33rd day of induction chemotherapy are associated with recurrence and death in children with ALL.
