1/5. hepatoblastoma associated with beckwith-wiedemann syndrome and hemihypertrophy.Both beckwith-wiedemann syndrome (BWS) and hemihypertrophy (HH) have been recognized to be overgrowth syndromes associated with an increased risk of cancer. We report an infant with hepatoblastoma associated with both BWS and HH in whom high serum alpha-fetoprotein (AFP) levels persisted even after complete tumor resection with no tumor recurrence. This phenomenon might be partly due to the nature of the proliferative disease. It is important to recognize that in some infants with BWS prolonged high serum AFP levels mimic the existence of a tumor, and that treatment should be based not only on AFP measurement, but also on repeated radiologic imaging.- - - - - - - - - - ranking = 1keywords = life (Clic here for more details about this article) |
2/5. Unresectable hepatic tumors in childhood and the role of liver transplantation.liver transplantation has been performed in five children with unresectable hepatic tumors who did not have extrahepatic metastases at the time of surgery. Two of the children had hepatoblastomas, one had an infantile hemangioendothelioma, and two had a hepatoma. The two children who had hepatoblastoma are well (37 and 25 months posttransplant) and have no evidence of recurrence. The child with infantile hemangioendothelioma had a successful operation, with good quality of life, but died of tumor recurrence 41 months after transplantation. Both children with hepatomas died, one of graft failure owing to chronic rejection and the other of tumor recurrence 5 months posttransplant. These results suggest that liver transplantation may be successful in children with unresectable hepatic tumors without extrahepatic spread and should be considered particularly for the treatment of hepatoblastoma.- - - - - - - - - - ranking = 1keywords = life (Clic here for more details about this article) |
3/5. hepatoblastoma in an infant with beckwith-wiedemann syndrome.A 3-month-old Chinese male infant with typical manifestations of beckwith-wiedemann syndrome (BWS), such as macroglossia, hepatomegaly, umbilical hernia and hypoglycemia, presented with a large hepatic tumor. The tumor measured 7.6 x 8.0 x 7.5 cm. An open biopsy of the tumor revealed hepatoblastoma. The family refused chemotherapy, so only supportive care was given. The tumor grew very rapidly and the infant died 17 days after admission due to respiratory failure. To our knowledge, this is the first report of BWS associated with hepatoblastoma in a Chinese infant. This patient was a typical example of the association of BWS and hepatoblastoma, and the possible effect of growth factors on the rapid proliferation of the neoplasm in BWS.- - - - - - - - - - ranking = 1keywords = life (Clic here for more details about this article) |
4/5. Mixed hepatoblastoma in an adult--a case report and literature review.hepatoblastoma is thought to originate from embryonal hepatic tissue, and most of these tumors occur in children under the age of 2 years. hepatoblastoma in adults is extremely rare, and the prognosis is much worse than the mixed hepatoblastoma of childhood. We experienced a case of mixed hepatoblastoma in a 51 year old female patient. She had been suffering from a mild pain and a palpable lump in the epigastric area. serum AFP was 43,850 ng/ml. Computerized tomography and selective abdominal angiography showed a large low-density mass. With a suspicion of hepatocellular carcinoma of the left lobe, a left lateral segmentectomy was performed. The external surface showed a huge protruding mass and the capsule was previously ruptured. On section, the tumor was a 11 x 7 cm sized expanding mass which had a variegated surface composed of yellow-white friable tissue with multifocal hemorrhagic areas. Microscopic examination revealed a tumor consisted of epithelial and mesenchymal elements. The mesenchymal cells were spindle in shape and proliferated over the whole tumor with focal osteosarcomatous differentiation. The epithelial components showed well-differentiated hepatocellular carcinoma-like areas, poorly differentiated acinar or tubular structures.- - - - - - - - - - ranking = 1keywords = life (Clic here for more details about this article) |
5/5. "Emergency hepatectomy" in a 16-month-old boy with a hepatoblastoma, severe cytomegalovirus-induced pancytopenia, and intractable diarrhea.A 16-month-old boy presented with massive abdominal enlargement. magnetic resonance imaging (MRI) revealed a liver tumor measuring 11 x 11 x 10 cm. Pulmonary metastases were detected by chest computed tomography. The diagnosis of a hepatoblastoma was made from the patient's age, the location of the tumor, and marked elevation of alpha1-fetoprotein (AFP). Chemotherapy according to the German Cooperative Pediatric Liver Tumor Study HB-94 was started, leading to a rapid and dramatic decrease in AFP levels. Despite an excellent response to chemotherapy, however, the abdominal distension increased. On a second MRI scan the tumor was unchanged in size, showing large areas of necrosis and cystic transformation. In addition, the patient acquired a cytomegalovirus infection with intractable diarrhea and severe pancytopenia. Since the patient's clinical course had worsened, the decision was made to alleviate the life-threatening tumor compression by an extended right hepatic lobectomy despite platelet-transfusion dependence and a white blood cell (WBC) count of only 300/microliter. Postoperative necrosis of the common bile duct necessitated a secondary resection with Roux-en-Y hepaticojejunostomy. The boy recovered quickly, and the white blood and platelet counts increased to normal values immediately after the first surgery so that chemotherapy could be finished after the postoperative recovery period. He is now in good condition without evidence of local or metastatic disease 1 year after the primary diagnosis.- - - - - - - - - - ranking = 1keywords = life (Clic here for more details about this article) |
