#4657 Should we use the growth modulation index (GMI) in response assessment in G2 neuroendocrine tumours (NETs)?

Introduction: Grade 2 (G2) neuroendocrine tumours (NETs) exhibit diverse behaviours ranging from indolent to aggressive malignancies. Growth Modulation Index (GMI) is the ratio between time to progression (TTP) with a line of therapy (TTPn) and that of the previous line of therapy (TTPn-1). A GMI value equal to or greater than 1,33 has been suggested as an indicator of clinical effectiveness beyond traditional metrics.

#4497 Complex management of a long-term gastrinoma survivor with multimodal treatment approaches

Introduction: The prognosis of pancreatic gastrinomas is influenced by tumour burden, extent of metastasis, and treatment response, with 5-year survival rates ranging from 20% to 40%. Treatment for well-differentiated tumours typically include locoregional therapies, long-acting somatostatin analogues, molecular targeted agents, radionuclides, and chemotherapy.

#4481 Predicting peptide receptor radionuclide therapy (PRRT) response through the landscape of the immune microenvironment in neuroendocrine tumours

Introduction: Neuroendocrine tumours (NETs) often have poor prognosis upon metastasis. Peptide receptor radionuclide therapy (PRRT) is a novel treatment leveraging targeted cytotoxicity of radionuclides to efficiently address primary and metastatic tumours of NETs.

#4333 Clinical efficacy of peptide receptor radionuclide therapy with radiolabelled somatostatin analogues (PRRT) of metastatic neuroendocrine tumours (NETs) – A single-centre cohort study

Introduction: PRRT is indicated for disease progression in patients with disseminated or unresectable NETs, especially those originating from the midgut. Up to date clinical trials have proven the efficacy of PRRT in gastrointestinal NETs, while data on other localisations are limited.
