Treatment of Hepatocellular Carcinoma
Treatment Options for Presurgically Staged (PRETEXT) Stage 4
- Chemotherapy followed by reassessment of surgical resectability followed by complete surgical resection of primary tumor.
The use of neoadjuvant chemotherapy followed by complete gross surgical resection of the primary tumor is necessary for cure.
- Chemotherapy followed by reassessment of surgical resectability. If the primary tumor remains unresectable, an orthotopic liver transplantation may be performed.
Liver transplantation has been successful therapy for children with unresectable hepatocellular carcinoma; survival is about 60% with most deaths resulting from tumor recurrence.[5,6,7]
- Chemotherapy followed by reassessment of surgical resectability. If the primary tumor remains unresectable, alternative treatment approaches may include the following:
- Intratumoral injection of alcohol.
- Transarterial chemoembolization.
- Radiation therapy.
No specific treatment has proven effective for unresectable hepatocellular carcinoma in the pediatric age group. A prospective study of 41 patients who were to receive preoperative cisplatin/doxorubicin chemotherapy resulted in some degree of decrease in tumor size with a decrease in AFP level in about 50% of patients. The responders had a superior tumor resectability and survival, although the OS was 28% and only those undergoing complete resection survived. The 5-year OS for PRETEXT stage 4 patients, including those with metastasis and/or extrahepatic disease, was 1 in 13. Cryosurgery, intratumoral injection of alcohol, and radiofrequency ablation can successfully treat small (<5 cm) tumors in adults with cirrhotic livers.[4,9,10] Some local approaches such as cryosurgery, radiofrequency ablation, and transarterial chemoembolization that suppress hepatocellular carcinoma tumor progression are used as bridging therapy in adults to delay tumor growth while on a waiting list for cadaveric liver transplant.[6,11,13] Transarterial chemoembolization has been used in a few children to successfully shrink tumor size to permit resection.[4,12] (Refer to the PDQ summary on Adult Primary Liver Cancer Treatment for more information.)
Treatment Options for Postsurgically Staged Stage IV
No particular treatment has proven effective for metastatic hepatocellular carcinoma in the pediatric age group. In two prospective trials, cisplatin plus either vincristine/fluorouracil or continuous infusion doxorubicin was ineffective in adequately treating 25 patients with metastatic hepatocellular carcinoma.[1,3] Occasional patients may benefit from treatment with cisplatin/doxorubicin therapy, especially if localized hepatic tumor shrinks adequately to allow resection of disease.
