Abstract

PURPOSE: Pancreatic tumors are relatively rare in children. Until now more than 150 cases have been reported in the English literature. In this paper, the authors report the tumors clinical characteristics and the results of surgery in eleven children.
MATERIALS AND METHODS
Eleven cases of pancreatic tumor pathologically verified at Seoul National University Children's Hospital between 1984 to 1998 were retrospectively analyzed. Four were boys and seven were girls, and their mean age at diagnosis was 7.7 (range, 2 13) years.
RESULTS
There were six solid and papillary epithelial neoplasms of the pancreas (SPENP) and five pancreatoblastomas. All children came to medical attention because of abdominal masses. Tumors ranged in size from 6.0X 5.0 cm to 10.5 x 8.0 cm. Eight tumors were located in head and three in tail. Complete excision was performed in eight cases (six in SPENP and two in pancreatoblastoma). Incomplete excision was performed in two cases of pancreatoblastoma. One patient with pancreatoblastoma had an unresectable tumor at the time of diagnosis and needle aspiration biopsy was done under the ultrasound guidance. No patient died during surgery. After a mean follow-up period of 4.1 years, all patients with SPENP were alive and there had been no recurrence. However, of two patients who received complete excision in pancreatoblastoma, one presented with liver metastasis at 4 months after operation and received chemotherapy, but died 6 months after operation. The other patient had local recurrence 1 year after operation. Reoperation and chemotherapy were performed and the child is now alive without evidence of disease montbs after the initial operation. All three patients with unresectable tumor died in spite of adjuvant radiotherapy and chemotherapy.
CONCLUSION
Pediatric pancreatic tumors comprise rare heterogenous groups of malignancies with their prognosis dependent upon adequate resection and pathologic classification. Complete resection of pancreatic tumors arising anywhere in the pancreas was recommended.
