Tumour lysis syndrome and congestive heartfailure: case report
A 17-year-old girl with metastatic choriocarcinomadeveloped tumour lysis syndrome and congestive heartfailure during chemotherapy with etoposide, methotrexate,dactinomycin, cyclophosphamide and vincristine (EMA-CO).
The girl, whose disease was complicated bythyrotoxicosis and sepsis, started receiving multiagentEMA-CO chemotherapy [dosages, routes and treatmentdurations not stated]. Two days before treatment cycle 2,she presented with severe dehydration secondary tointractable nausea and vomiting. Laboratory investigationsrevealed acute renal failure with elevated potassium andphosphorus levels. Findings were consistent with tumourlysis syndrome, and she was admitted to an ICU.
Despite receiving 6 days of aggressive hydration therapyand allopurinol, the girl’s uric acid level remained elevated.She then received a dose of rasburicase. Her uric acid levelbecame undetectable in 3 days.
Due to multiple complications, including tumour lysissyndrome, deep vein thrombosis, oesophagitis andfungaemia, the girl’s second therapy cycle was delayed by3 weeks. Her EMA-CO chemotherapy dosages weredecreased by 50%, and aggressive hydration andrasburicase were administered as prophylaxis for tumourlysis syndrome. Her third cycle of EMA-CO chemotherapywas administered without delay (at a 25% dose reduction).Pulmonary oedema necessitated intubation on days 2–8 ofcycle 3; however, day 8 doses were administered withoutdelay following extubation. At this point echocardiographyrevealed congestive heart failure and an ejection fraction of20%; these findings were confirmed on repeatechocardiography 1 week later. Cycle 4 was administeredas scheduled. However, pulse dactinomycin wasadministered on day 8 instead of cyclophosphamide andvincristine.
The girl received a total of five cycles of pulsedactinomycin, with two further cycles after testing wasnegative for serum β-human chorionic gonadotropin. Atlast observation, her ejection fraction had improved to45%.Schuman S, et al.
