A multi-institutional study investigated the accuracy of preoperative imaging in detecting lymph node metastasis (lnm) in patients with pancreatic neuroendocrine tumors (pnets). They found that traditional imaging modalities such as computed tomography (CT), magnetic resonance imaging (MRI), positron emission tomography (PET)-CT, and octreoscan had low sensitivities to determine nodal status. Preoperative imaging indicating nodal involvement (in1) was associated with a higher number of lymphadenectomies and a higher risk of recurrence compared to preoperative imaging indicating no nodal involvement (in0).
