N2 - BACKGROUND: Hepatoblastoma (HB) is the most common liver tumor of childhood, and comprises approximately 1% of all pediatric malignancies. Although recent data from multicenter trials of GPOH, SIOP, CCG and POG indicate a remarkable improvement of therapy results, the prognosis of advanced or recurrent HB is still not satisfying. PATIENTS AND METHODS: During 1989 and 1997, the German Cooperative Pediatric Liver Tumor Studies HB 89 and HB 94 registered 141 patients with HB, who were treated according to the study protocols. These patients received standard chemotherapy with ifosfamide, cisplatin and doxorubicin (IPA) pre-operatively and/or post-operatively. Fourteen children with recurrent or advanced HB were additionally treated with carboplatin and etoposide (CARBO/VP 16), the reason being observations of drug resistance in children with HB after four or more courses of IPA-therapy in the HB 89 study. The clinical data and course of these patients were evaluated to investigate the efficiency of CARBO/VP 16 chemotherapy and for analyzing the role of surgery. RESULTS: Mean follow-up for survivors was 4.3 years (range 13 months-8 years). Tumor resection was attempted in 13 children but, in only 3 cases, was a complete tumor resection achieved in one operation. There was no perioperative death, and 7 of the patients (50%) are in remission. Two patients underwent adjuvant chemotherapy with CARBO/VP 16 for advanced HB at first operation: all are alive and well. Five patients with local relapse and/or distant metastases responded partially to CARBO/VP 16 therapy, and a complete remission was achieved in one patient. In five patients, progressive disease was observed during therapy with CARBO/VP 16. One patient, stable while on chemotherapy, had a successful resection. Acute toxicity of chemotherapy was observed in 7 patients (50%). CONCLUSION: An aggressive approach using IPA and CARBO/VP 16 chemotherapy and highly developed surgical techniques may improve the prognosis of advanced or recurrent HBs.
