Summary
Brief summary (as posted)
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.

- Active surveillance group
- description
- Advised surveillance strategy consists of imaging studies (MR or EUS or US), every 6 months for the first two years and yearly thereafter for five years in the absence of significant changes on imaging or symptoms appearance. During surveillance, a high-quality imaging technique (MRI or CT) is mandatory at least every 12 months. Determination of CgA during follow-up is at physician's discretion. During follow-up, the treating physician is responsible for patient management and decision-making.

- Surgical resection group
- description
- Timing and type of resection will be established by the treating physician. Follow up strategy after surgery consists of imaging studies (MR or CT), every 6 months for the first two years and yearly thereafter for five years. An high-quality imaging technique (MRI or CT) is mandatory at least every 12 months. Determination of CgA during follow-up is at physician's discretion. During follow-up, the treating physician is responsible for patient management and decision-making. Date of surgery does not change the timing of follow up which starts from the date of enrolment.

Inclusion Criteria: * Age \> 18 years * Individuals with asymptomatic sporadic NF-PNEN ≤ 2 cm * Diagnosis has to be proven by a positive fine-needle aspiration (FNA) or by the presence of a measurable nodule on high-quality imaging technique (CT or MR) that is positive at 68Gallium DOTATOC-PET scan or Octreoscan. * Patients who undergo surgery for NF-PNEN\<2cm within 12 months. In these cases, diagnosis has to be proven by histological confirmation of NF-PNEN * Informed consent Exclusion Criteria: * NF-PNEN \> 2 cm of maximum diameter * Presence of genetic syndrome (MEN1, VHL, NF) * Presence of symptoms (specific symptoms suspicious of a clinical syndrome related to hypersecretion of bioactive compounds) or unspecific symptoms
