title: [Multidisciplinary management of malignant hepatic tumors in children: a recent national experience].
abstract: BACKGROUND
  Malignant hepatic tumors (Mht) are rare in children. Among them hepatoblastoma (HB) is the most common.
  
  
  OBJECTIVE
  To report the results of the multidisciplinary management in 6 consecutive children: five HB and one metastatic Wilms tumor (MWT).
  
  
  METHODS
  The mean age of patients was 42 months. All HB patients had elevated serum alfafetoprotein (median 150,000 ng/ml). All patients received preoperative chemotherapy: HB patients received carboplatin/doxorubicin alternating with cisplatin, and the MWT patient, vincristine alone. Surgery included two formal right and two formal left hepatectomies, one extensive central resection with partial left segmentectomy, and one lateral segmentectomy. Extracorporeal circulation was used in the child with atrial involvement. All patients received postoperative chemotherapy.
  
  
  RESULTS
  All tumors had variable regresion on preoperative chemotherapy. Complete resection with negative margins was achieved in all patients. The degree of tumor necrosis on histology ranged from 60% to 90%. Alfafetoprotein levels fell to under 10 ng/ml in all HB cases, one to three months after surgery. All patients survive free of disease at a median follow up of 19 months.
  
  
  CONCLUSIONS
  A multidisciplinary approach including the well timed used of chemotherapy and surgery is highly effective in the management of pediatric malignant tumors.
