FDG-PET is Superior to WHO Grading in Predicting Overall Survival of Patients with Neuroendocrine Tumors: A Prospective Study of 172 Patients Abstract #1789

Introduction: Accurate grading of patients with neuroendocrine tumors (NETs) is essential for risk stratification and optimal choice of therapy. Currently, WHO grading is based on histo-pathologically assessed degree of tumor proliferation.
Aim(s): To assess the prognostic value of FDG-PET imaging for risk stratification of NETs and compare it with WHO grading.
Materials and methods: We conducted a prospective, single-center cohort study evaluating the prognostic value of FDG-PET imaging and compared it to the current WHO grading. Patients (n = 172) of all grades and with histologically confirmed NETs of gastroenteropancreatic or pulmonary origin were enrolled. The primary end point was overall survival (OS). Progression-free survival (PFS) was a secondary end point.

#2717 64Cu-DOTATATE PET/CT Predicts Progression-Free Survival in Patients with Neuroendocrine Neoplasms
Introduction: The degree of overexpression of somatostatin receptors in patients with neuroendocrine neoplasms (NEN) may reflect tumor differentiation and thus be associated with prognosis. Non-invasive quantification of receptor density is possible by somatostatin receptor imaging (SRI) using positron emission tomography (PET).

Introduction: Practical and economic challenges limit the widespread use of 68Ga-labeled somatostatin analog (SSA) PET, the current standard for somatostatin receptor imaging. A promising 18F-labeled SSA, Al18F-NOTA-octreotide (Al18F-OC), has recently been introduced.
