#4665 Prognostic value of systemic inflammatory parameters in neuroendocrine tumour patients treated with peptide receptor radionuclide therapy – Preliminary results

Introduction: PRRT (177Lu-Dotatate) is a therapeutic option for advanced NETs (neuroendocrine tumours). Systemic inflammatory parameters, such as NLR, PLR, SII, and other ratios derived from complete blood counts, are considered prognostic markers in NETs and other malignancies.

#4561 Prognostic value of pre-therapeutic and interim SSTR PET in patients with GI-NET receiving peptide receptor radionuclide therapy

Introduction: Baseline and interim (after 2 cycles) somatostatin receptor (SSTR)-directed PET/CTs are essential in patients with gastrointestinal neuroendocrine tumours (GI-NET) undergoing peptide radioreceptor therapy (PRRT).

#4398 The role of chromogranin A as a biomarker in neuroendocrine tumours: Diagnostic and prognostic implications

Introduction: Chromogranin A (CgA) is a widely used serum biomarker for neuroendocrine tumours (NETs), reflecting tumour burden and secretory activity. Despite its clinical utility, the diagnostic sensitivity and prognostic value of CgA remain a subject of debate, especially given its potential for false positives and its variation across different NET subtypes.

#4324 The diagnostic and prognostic value of 68Ga-DOTANOC and 18F-FDG PET/CT for thymic carcinoids

Introduction: Thymic carcinoid (ThC) is an extremely rare type of neuroendocrine tumour. There is insufficient evidence to evaluate ThC using 68Ga-DOTANOC and 18F-FDG PET/CT.

#3984 The contribution of functional imaging in predicting the risk of recurrence after pancreatic surgery for neuroendocrine tumors

Introduction: Pancreatic neuroendocrine tumors (pNETs) are rare and heterogeneous, comprising 1 to 3% of all pancreatic neoplasms. The recurrence rate of non-metastatic pNETs varies, reaching up to 50% depending on the series, highlighting the difficulty in selecting candidates for surgery. However, there is no published data regarding the prognostic value of functional PET imaging combined with clinical and pathological characteristics.
