The Use of Single Dose of Rasburicase for the Prophylaxis and Treatment of Tumor Lysis Syndrome in Pediatric Patients: A Narrative Review

Year: 2025
Type: review
Abstract: Background/Objectives: Rasburicase is licensed for the management of tumor lysis syndrome (TLS) at a daily dose of 0.2 mg/kg intravenously for five days. The use of a single-dose treatment is popular in adult oncology but information in pediatric use is limited. Methods: From a literature search, all case reports and series, and comparative studies in which pediatric oncology patients received a single dose of rasburicase were selected for further analysis. Treatment success was determined by normalization of serum uric acid in the absence of serious complications. Results: Twelve articles with a total of 243 children were included. A fixed-dose regimen was used in 195, while 153 received weight-based dosing. With fixed dosing, successful treatment was seen in 91.8% and 82.9% at rasburicase doses ≥3 mg and 1.5 mg, respectively (p = 0.23). However, there were four mortalities in the lower-dose group. For weight-based dosing, success was observed in 89.2% and 66.7% at doses ≥0.15 mg/kg and <0.15 mg/kg, respectively (p = 0.0029). One child required dialysis in the lower-dose group. Conclusions: Single dose of rasburicase for the prophylaxis and treatment of TLS in pediatric oncology is an appealing approach with potentially less financial impact and drug toxicity. A fixed dose of at least 3 mg or 0.15 mg/kg by body weight is recommended.
