Clinical Trial Summary

The aim of the study is to evaluate the most appropriate management of sporadic asymptomatic non-functioning pancreatic neuroendocrine neoplasms (NF-PNEN) ≤ 2 cm. P NF-PNEN management will be decided at the hospital and all therapeutics decision will be decided/coordinated by the treating physician. Patients will be either submitted to surgical resection or to active surveillance.


Clinical Trial Description

In the last decade a dramatic increase in diagnosis of small, incidentally discovered, NF-PNEN was observed. Various study indicates the safety of a conservative management for this lesion and the The European Neuroendocrine Tumor Society (ENETS) proposed a "wait and see" approach for small NF-PNEN. Indications for surgery include the presence of a localized NF-PNEN in the absence of distant metastases as curative resection of these tumors is associated with favourable prognosis especially for low grade. In the last decade a dramatic increase in diagnosis of small, incidentally discovered, NF-PNEN was observed.Moreover, other investigators observed a clear relationship between the tumor diameter and low risk of malignancy and systemic progression. In particular, a tumor size ≤ 2 cm seems to be associated with a negligible risk of disease recurrence and with a very low incidence of aggressive features such as lymph node involvement.On this basis, the European Neuroendocrine Tumor Society (ENETS) proposed a "wait and see" approach for small NF-PNEN when incidentally discovered. Since then, various series evaluated the safety of a conservative management for small, sporadic, incidentally diagnosed, NF-PNEN. After a median follow-up of 28-45 months, all the studies confirmed that an intensive surveillance for incidental and small NF-PNEN is safe in selected cases. Nevertheless, available data are based only on retrospective series with a significant heterogeneity of inclusion criteria and different tumor diameter cut-off and the appropriate management of this entities (surveillance versus surgery) is still a matter of debate. ;
