Abstract

OBJECTIVE
The clinical features and prognosis of intraductal papillary mucinous tumor (IPMT) of the pancreas are diverse. We reviewed the clinicopathologic features and surgical results of patients who were treated for IMPT.
METHODS
WE retrospectively reviewed seven cases that were surgically resected and pathologically diagnosed.
RESULTS
The mean patient age was 63.7 years and there were 6 (85.7%) symptomatic patients. The diagnostic accuracy of abdominal CT was 57.1% (n=4) and the was 71.4% (n=5). (Ed note: the last part made no sense. Put in the correct terms.) The final diagnosis was benign IPMT in 4 cases (57.1%), malignancy in 3 cases (42.9%, and borderline malignancy, carcinoma in situ and invasive carcinoma in one case each, respectively). Three cases each of pylorus preserving panreaticoduodectomy (42.9%) and distal pancreatectomy were performed (42.(%), respectively, and 1 pancreatic wedge resection (14.3%) was performed for 1 case. Three patients (42.9%) were found to have associated malignancies. The median follow-up duration was 10 months (range: 3-25). Four patients are still alive and 3 patients have died, but only one patient died of systemic metastasis.
CONCLUSION
The clinicopathological features, treatment, and prognosis of IPMT are still unclear, but the significant possibility of malignancy and associated malignancies should always kept in mind and further study is required
