#4614 Rare diagnosis of intrapancreatic accessory spleen mimicking PanNET

Introduction: A 44-year-old woman with hypertension and an autoimmune thyroid disease. With a positive family history of pancreatic and oesophageal cancer. Referred to our clinic for an incidental finding of a tumour in the tail of the pancreas on abdominal ultrasound by a surgeon.

#4523 Preoperative evaluation of tumour border using radiomics and its surgical guidance in pancreatic neuroendocrine tumours

Introduction: Pancreatic neuroendocrine tumours are a heterogeneous group of tumours originating from peptidergic neurons and neuroendocrine cells with variable survival outcomes. Surgical resection is the mainstay of treatment. However, there is an ambiguous insight into the real need to execute the standard surgery in small pancreatic neuroendocrine tumours. The tumour border is a powerful determinant of survival prognosis in many tumours and is often used as a safety guarantee for parenchyma-sparing resections. However, there are no studies evaluating tumour border with or without preoperative imaging in pNETs.

#4143 Portal vein resection in pancreatic neuroendocrine neoplasms

Introduction: Surgery offers the only cure in borderline resectable or locally advanced neuroendocrine neoplasms of the pancreas (pNEN). Data on incidence and postresection outcome of portal vein resection (PVR) for pNEN are scarce.

#4115 Neoadjuvant PRRT with 90Y-DOTATOC: Preliminary results from a monocentric perspective study

Introduction: Surgery is considered the only curative treatment for pancreatic neuroendocrine tumors (pNETs), but it is feasible only in a few patients. A new possible strategy in pNETs is preoperative PRRT, as its cytoreductive effect could increase the efficacy of surgery.

#4031 68-Gallium DOTANOC PET/CT pitfall in adnexal tumor

Introduction: PET/CT with 68Ga-DOTA is a commonly used tool in the baseline evaluation and follow-up of NETs due to its high specificity and sensitivity, showing better performance than CT in detecting primary and metastatic disease. However, we must know more about its normal physiological distribution, its variation in pathologies, and the possibility of confusion with benign processes to optimize its interpretation.
