Official title
Somatostatin Receptor Antagonist PET/CT for Pre-operative N Stage Evaluation in Patients With Gastro-entero-pancreatic Neuroendocrine Tumors
Overview
The research aims to prospectively include patients with GEP-NENs, undergo preoperative imaging assessment (including PET/CT and contrast-enhanced CT), and accurately delineate lymph node regions. Through postoperative pathological reports, the diagnostic performance of lymph node metastasis (LNM) in GEP-NENs is evaluated. Factors influencing the diagnostic accuracy of SSTR-PET/CT and contrast-enhanced CT are also investigated.
Primary outcome measures
- lymph node metastasis status [Time frame: 2024.04.01~2030.03.01]
Eligibility criteria

Exclusion criteria
- Presence of concomitant malignancies;
- Cases diagnosed pathologically as non-GEP-NEN.
Criteria are shown verbatim from the registry (in English). Final eligibility is always assessed by the study center.
