title: Pancreatoblastoma in children. Case report and review of the literature.
abstract: Pancreatolblastomas are rare embryonal malignancies in childhood. We report a 3-year-old girl with a tumor of the head of pancreas. Staging by bone scintigraphy and CT scans of abdomen and chest did not show evidence of metastatic disease. Tumor markers showed elevated levels of alpha-1 fetoprotein (64 ng/ml; normal 0-10 ng/ml) and lactate dehydrogenase (423 U/l; normal range below 300 U/l). The tumor was macroscopically completely removed by local resection. Postoperative tumor grading was pT1, NO, MO. The child recovered very soon after surgery without severe complications. Tumor markers dropped to normal values, indicating complete remission (follow-up time 12 months). According to the biological growth characteristics of pancreatoblastomas and to the literature, localized and non-metastatic tumors should be completely resected without radical pancreatoduodenectomy and without adjuvant chemotherapy. This is the most conservative therapy with a good prognosis. However, metastatic disease, primarily inoperable conditions or local relapses are indications for chemotherapy combined with radiotherapy and followed by resection of the tumor. At present, the prognosis of such cases is rather poor.
