Stage IV hepatoblastoma

The outcome for hepatoblastoma that is metastatic at diagnosis is not good, but cure is possible in 25% to 30% of patients.[1-4] In a study employing a well-tolerated regimen of doxorubicin/cisplatin chemotherapy, over 50% of patients with metastases at presentation survived 5 years from diagnosis. Half of these survivors developed progressive disease that was successfully treated with surgery and other interventions.[1-5] If possible, stage IV patients with resected primary tumor should have any remaining pulmonary metastases surgically removed. A randomized clinical trial has demonstrated equal efficacy with cisplatin/vincristine/fluorouracil and cisplatin/doxorubicin in the treatment of hepatoblastoma; the combination of cisplatin/vincristine/fluorouracil, however, resulted in considerably less toxicity.[3] A combination of ifosfamide, cisplatin, and doxorubicin has also been successfully used in the treatment of advanced-stage disease.[6] Patients whose tumors remain unresectable should be considered for alternative chemotherapy, such as high-dose cisplatin with etoposide,[7] radiation therapy,[2,8] direct hepatic infusion of chemotherapeutic agents,[9,10] or, if metastatic disease is controlled, orthotopic liver transplantation.[4,11-13]

Standard treatment options
Four courses of cisplatin/vincristine/fluorouracil [3] or doxorubicin/cisplatin combination chemotherapy followed by attempted complete tumor resection. If the tumor is completely removed, 2 postoperative courses of the same chemotherapy should be given. If the tumor is not resectable after 4 courses of chemotherapy, alternative therapies should be considered.

Alternative therapies
Chemotherapy with high-dose cisplatin/etoposide or continuous infusion of doxorubicin.


Radiation therapy followed by re-exploration if metastatic disease is controlled.


Chemoembolization by hepatic arterial infusion.


Orthotopic liver transplantation if metastatic disease is controlled.


Phase I or II clinical trials of chemotherapy.


Stage IV hepatocellular carcinoma
In a randomized trial, cisplatin plus either vincristine/fluorouracil or doxorubicin given by continuous infusion was ineffective in adequately treating unresectable hepatocellular carcinoma. Therapy failed in 13 of 13 patients with stage IV disease.[14] No particular treatment for unresectable hepatocellular carcinoma has proved especially effective in the pediatric age group. Occasional patients may benefit from treatment with cisplatin/doxorubicin therapy, especially if localized hepatic tumor shrinks adequately to allow resection of disease. (Refer to the PDQ summary on Adult Primary Liver Cancer Treatment for more information.)
