#4609 External validation of Rachel score: A prognostic tool for lung neuroendocrine tumours

Introduction: Lung NETs are a heterogeneous group of tumours with variegated clinical presentation and course. The histological subtype (TC vs AC) and TNM stage are established prognostic factors. In a previous work by our group, we developed a prognostic model named Rachel score, with a satisfactory ability to predict OS and PFS in this population.

#4227 Evaluation of circulating extracellular vesicles as suitable prognostic markers in MEN1-associated non-functioning pancreatic neuroendocrine neoplasia

Introduction: Non-functioning pancreatic neuroendocrine neoplasias (NF-pNENs) significantly contribute to premature death of multiple endocrine neoplasia type 1 (MEN1) patients. Reliable prognostic markers for disease progression are lacking. Circulating liquid biomarkers, including microRNAs and Long-non-Coding (LnC) RNAs in extracellular vesicles, are emerging as new prognostic tools.

#3565 Grade 3 neuroendocrine neoplasms – Real life experience and prognostic biomarkers

Introduction: Grade 3 neuroendocrine neoplasms (G3 NEN) are a heterogeneous group, including well differentiated tumors (NET) and poorly differentiated carcinomas (NEC), whose identification can be challenging. Accessible prognostic tools are needed to individualize treatment. Data suggests neutrophil/lymphocyte ratios (NLR) and systemic inflammatory index (SII) have prognostic value in NEN.

#3468 Novel morphological tools in predicting pancreatic neuroendocrine tumors (Pan-Net) clinical outcome

Introduction: Pancreatic Neuroendocrine Tumor (Pan-NET) clinical outcome shows a high variability among patients within the same World Health Organization (WHO) category. To date, there is a lack of markers to predict recurrence after resection, which makes it difficult to identify patients with higher risk of progression.

#3446 Metabolomic profile of extra-pancreatic NET: A novel prognostic tool?

Introduction: Reprogrammed metabolism is one of the key hallmarks of cancer. Thus, metabolic profiling of cancer patients represents a promising tool. To date, metabolomics remains largely unexplored in NETs.
