#4660 Clinical significance of interval imaging in patients with well-differentiated neuroendocrine neoplasms (NENs) receiving peptide receptor radionuclide therapy (PRRT)

Introduction: PRRT is an effective therapy for advanced NENs with SSTR-avid disease, however, the role of interval imaging in between PRRT cycles and its benefit is unknown.

#3627 Early prediction of the efficacy of 177Lu-DOTATATE in patients with metastatic neuroendocrine tumors

Introduction: PRRT has a major place in the therapeutic strategy of metastatic NETs. Its efficacy is generally evaluated after four cycles, with no early predictor identified to date. During each PRRT cycle, 177Lu-related gamma emissions can be measured by post-PRRT scintigraphy.

#3563 Can tumor absorbed dose predict response to Peptide Receptor Radionuclide Therapy (PRRT) in patients with gastroenteropancreatic neuroendocrine tumors (GEP-NETs)?

Introduction: Tumor dosimetry protocols following Peptide Receptor Radionuclide Therapy (PRRT) have not yet been standardised and tumor absorbed dose does not hold clear value in predicting response to treatment.
