BACKGROUND/AIMS: The authors reviewed their experience with resected IPMT (intraductal papillary-mucinous tumor) of the pancreas to clarify the characteristics and prognosis of this neoplasm. METHODOLOGY: Between 1983 and 1998, 30 consecutive patients with IPMT underwent operations at our institution. Their clinicopathological features and postoperative long-term outcomes were analyzed retrospectively. RESULTS: There were 22 males and 8 females, with a mean age of 64 years. Operations performed were duodenum-preserving pancreatic head resection in 12 patients, distal pancreatectomy in 8, segmental pancreatectomy in 6, conventional pancreaticoduodenectomy in 4. Malignancy was found in 10 of 30 (33%). Factors significantly associated with malignancy were tumor size or presence in main pancreatic duct. In 30 resected patients after a mean follow-up of 60 months, tumor recurrence had occurred in 2 cases of invasive carcinoma that infiltrated into the extrapancreatic organ. The overall actuarial 5-year and 10-year survival was 83% and 62%, respectively. CONCLUSIONS: IPMT has a favorable prognosis after adequate resection. Despite slow growth, IPMT has an obvious malignant potential and a poor prognosis when invasive carcinoma has developed. Early recognition and pancreatectomy is the mainstay of treatment for IPMT.
