At the 'Outcomes Research—Lymphoid Malignancies: Poster II' session, Yoona Choi, serving as the first author and representing the entire research team, presented a study titled 'Evaluating the Effectiveness and Safety of Prephase Steroid Treatment before Remission Induction Chemotherapy in Pediatric Acute Lymphoblastic Leukemia: A Common Data Model-Based Real-World Data Approach.' This study investigated steroid pretreatment in pediatric acute lymphoblastic leukemia (ALL) patients undergoing remission induction chemotherapy (RIC), with the aim of reducing complications such as tumor lysis syndrome (TLS). Analyzing data from Seoul National University Hospital and Catholic University Seoul St. Mary’s Hospital, the study compared patients who received steroid pretreatment at least seven days before RIC with those who did not. The findings indicated a significant reduction in TLS incidence in the pretreated group. While overall survival rates were higher in this group, the difference was not statistically significant. These results provide important real-world evidence for the effectiveness of steroid pretreatment in reducing TLS risk in pediatric ALL patients.

This study was part of a larger project, funded by a grant from the Ministry of Health and Welfare, aiming to develop a disease registry database for pediatric ALL using real-world data in the clinical data warehouse (CDW) of Seoul National University Hospital and Catholic University Seoul St. Mary’s Hospital, thereby generating real-world evidence for pediatric ALL.
