Background and aims
Intraductal tubulopapillary neoplasms (ITPNs) of the pancreas are rare. The purpose of this study was to collate and analyze published data on ITPNs of the pancreas to determine the clinicopathological features of the tumors and the surgical outcomes of patients.
Patients and methods
We searched MEDLINE and Igakuchuo-Zasshi for the period of 1980 to 2015 for case reports on surgical resection for ITPN of the pancreas. We evaluated the clinicopathological data associated with pancreatic ITPNs, the prognosis for each patient, and surgical outcomes described in the case reports.
Results
We obtained clinicopathological data for 58 patients (33 men and 25 women) with a mean age of 61 years (range, 35–84 years) who had undergone surgical resection for ITPN of the pancreas, including one patient from our clinic. Although ITPNs of the pancreas have different clinicopathological features to intraductal papillary mucinous neoplasms, the treatment strategy for patients with ITPNs is the same as for patients with other cystic neoplasms of the pancreas. The immunohistochemical features of ITPNs included testing positive for cytokeratin 7 and/or cytokeratin 19 and negative for trypsin, MUC2, MUC5AC, and fascin. The overall 1-, 3-, and 5-year survival rates after surgery for the 37 cases with available data were 97.3, 80.7, and 80.7 %, respectively.
Conclusion
Surgical treatment is the only curative management option for patients with ITPN of the pancreas. To determine the best management strategy for this tumor and improve accuracy of prognosis for patients, we will continue to collect and analyze epidemiological and pathological data.
