About this trial

The aim of this observational multicenter retrospective cohort study is to evaluate the differences in risk factors, prognosis, clinicopathological and metabolic characteristics between early-onset pancreatic neuroendocrine tumors (EO-PanNETs) and late-onset pancreatic neuroendocrine tumors (LO-PanNETs).

The main questions it aims to answer are:

Are there distinct clinical, pathological, and metabolic profiles in EO-PanNETs compared with LO-PanNETs? Do EO-PanNETs have different prognostic outcomes compared with LO-PanNETs? Researchers will compare EO-PanNET patients with LO-PanNET patients and with matched nonmalignant controls to assess differences in tumor characteristics and associated metabolic conditions.

Participants will:

Provide retrospective clinical, pathological, and metabolic data from hospital records.

Have survival and recurrence outcomes assessed through follow-up data review.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

18 years or older; histopathologically confirmed pancreatic neuroendocrine tumor by surgical resection or biopsy.

Disqualifiers

Pancreatic neuroendocrine carcinoma; incomplete pathological data; received antitumor treatment prior to presentation; with other malignanies or malignant history.

Trial population

The study population comprised adult patients (≥18 years) diagnosed with pancreatic neuroendocrine tumors (PanNETs) between 2013 and 2024. All cases had a histopathologically confirmed diagnosis and received treatment at one of the participating centers. Patients were excluded if they had poorly differentiated neuroendocrine carcinoma, mixed neuroendocrine-non-neuroendocrine neoplasm, undefined tumor differentiation, recurrent disease, non-initial treatment, or a history of other malignancies.
