Veno-Occlusive Disease-Like Hepatotoxicity in two Children Receiving Chemotherapy for Wilms' Tumor and Clear Cell Sarcoma of Kidney

Abstract

We report two pediatric cases who developed veno-occlusive disease—like hepatotoxicity while receiving chemotherapy for Wilms' tumor and clear cell sarcoma of kidney. The chemotherapeutics, including vincristine, actinomycin D, and epirubicin in case 1 and vincristine and actinomycin D in case 2, were given before the hepatotoxicity developed. Other possible causes of hepatotoxicity were excluded. Recovery was observed with supportive therapy after 2 and 1 weeks, respectively. After recovery, the children tolerated continued chemotherapy without any decrease in the doses of drugs. We conclude that vincristine and actinomycin D were the cause of this rare form of hepatotoxicity and that chemotherapy for the underlying malignant disease could be given safely after clinical recovery.
