Abstract

BACKGROUND: Tumor lysis syndrome (TLS) is an extremely rare complication of solid tumors and is more frequently observed in patients with hematologic alignancies. This report describes a novel approach to the management of a rare case of TLS in metastatic gestational trophoblastic neoplasia (GTN). CASE: A 17-year-old female presented 8 weeks postpartum with severe anemia, thyrotoxicosis, and elevated serum β-human chorionic gonadotropin (β-hCG). Imaging studies confirmed metastatic GTN to the lungs. The patient developed grade 4 TLS after the first cycle of etoposide, methotrexate, dactinomycin, cyclophosphamide, and vincristine (EMA-CO). She id not respond to standard treatment of aggressive hydration and allupurinol and continued to be in renal failure with elevated uric acid. A single dose of recombinant urate oxidase, rasburicase, rendered the uric acid level undetectable in 3 days and completely reversed the renal failure, avoiding hemodialysis. Three more cycles of EMA-CO were then administered. Subsequently, the patient developed congestive heart failure and was switched to single-agent actinomycin-D. β-hCG became negative after 5 cycles, and her ejection fraction returned to baseline. CONCLUSION: This is a rare case of TLS in the setting of metastatic GTN. To our knowledge this is the first reported case of utilizing rasburicase for the management of TLS in GTN.
