#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.

#4649 Claudin 18.2 overexpression in gastric neuroendocrine tumours

Introduction: Claudin 18.2, is a tissue biomarker physiologically expressed in both healthy gastric mucosa and gastric adenocarcinoma which represents a novel therapeutic target advanced gastric cancer. Various other cancers showed some overexpression of claudin 18.2 opening potential opportunities to agnostic targeted therapy. However, data about claudin 18.2 expression in NENs are poor with only an Eastern study showing higher rate of claudin 18.2 positivity in GEP-NENs, mainly from gastric primary site (27.8%).

#4633 Mini invasive pancreatectomy for pancreatic neuroendocrine tumours: Current state of management in France

Introduction: Pancreatic neuroendocrine tumours (NETs) accounts for 2% of pancreatic tumours and their management is challenging. Surgery is the most radical treatment, but for small lesions, parenchyma sparing techniques are also used.

#4620 Impact of the extent of surgical resection on the development of post-operative diabetes in patients undergoing distal pancreatectomy for non-functioning pancreatic neuroendocrine tumours (NF-PanNET)

Introduction: Pancreatic neuroendocrine tumours (PanNETs) are often indolent neoplasms. Surgery is the primary curative approach for localised non-functioning (NF) PanNETs, but it poses a risk of long-term complications, such as diabetes, impacting quality of life.

#4612 Intraoperative beta-probe for pathological tissue detection in GEP-NET patients: A prospective phase II trial

Introduction: Accurate localisation of gastroenteropancreatic neuroendocrine tumours (GEP-NET) is essential for successful radical surgery. Radio guided surgery (RGS) is an innovative technique that may enhance lesion detection.
