Abstract
Sixteen children, aged 16 days to 13 years with hepatoblastoma (HB) (13 patients) or hepatocellular carcinoma (HCC) (3 patients), were given a total of 89 courses of cisplatin and doxorubicin (PLADO) as IV continuous infusion. All tumors were confined to the liver except for 1 hepatoblastoma patient with pulmonary metastases at presentation. Tumor response to PLADO was evaluable in 10 children (8 HB, 2 HCC) treated with preoperative chemotherapy and in another 2 HB patients treated when they developed pulmonary metastases after initial treatment with surgery alone. There were 2 complete responses (2 HB with pulmonary recurrences), 7 very good partial responses (6 HB and 1 HCC), 2 partial responses (1 HB, 1 HCC), and 1 stable disease (HB). The last patient underwent orthotopic liver transplantation whereas all the other patients had their tumor completely excised at delayed surgery. Documented toxicity was BM depression (16 patients), infection (11), vomiting (11), mucositis (3), hearing loss (1), and cardiotoxicity (1). These data indicate that PLADO in continuous infusion is effective in the treatment of malignant epithelial liver tumors with acceptable toxicity.
