Surgical resection and chemotherapy improve survival rate for patients with hepatoblastoma

Background: The authors reviewed retrospectively their experience in 30 children with hepatoblastoma (HB), Despite an increased trend in the incidence of HB during the last 2 decades, an encouraging cure rate has been achieved with complete resection of the tu mor a nd chemotherapy before or after surgery with cisplatin plus doxorubicin (Adriamycin) or cisplatin plus vincristine plus 5-Fluorouracil. Results: There were 10 female and 20 male patients. For the period from 1963 to 1980 there were 8 patients, and for the period from 1981 to 1998 there were 22 patients. Their mean age at surgery was 16 months (range, 3.5 months to 5.5 years). Tumors were localized to the right lobe in 10 (42%), to the left lobe in 7 (29%), and in both lobes in 7 (29%) of the resected patients. Tumors were greater than 10 cm in size in 16 (67%) of these patients, Twenty-four patients (80%), underwent liver resection before or after chemotherapy. One patient (3%) with an unresectable tumor received chemotherapy and a liver transplant. In 5 patients (17%) the hepatic involvement was too extensive for resection. The types of resection performed were right lobectomy in 7, left lobectomy in 6, right trisegmentectomy in 8, left trisegmentectomy in 2, and middle hepatectomy in 1. The overall survival rate for 35 years of the study was 60% (18 of 30). With the association of surgery and chemotherapy (1981 through 1998) survival rate is 82% (14 of 17). Overall median follow-up in our study is 8 years (range, 2.5 to 24 years). Conclusions: There has been a dramatic improvement in the results of treatment of hepatoblastoma. Formerly, only 25% to 30% of patients were cured, whereas today, with combination of chemotherapy and surgery, 75% to 80% may be cured. J Pediatr Surg 36:755-759. Copyright (C) 2001 by W.B.
