#4377 Characteristics of endoscopic ultrasonography in patients with gastrointestinal and pancreatic neuroendocrine tumours

Introduction: Neuroendocrine tumours are most commonly found in the gastrointestinal tract. With the development of endoscopic ultrasound, the incidence of GEP-NENs has increased year by year.

#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.

#3855 Contrast-enhanced and tissue harmonic endoscopic ultrasound for pancreatic neuroendocrine tumor diagnostic

Introduction: Endoscopic ultrasonography (EUS) is an examination using ultrasound and an endoscopic device, designed to image digestive tract and adjacent organs. The combination of tissue harmonic endoscopic imaging (THI) and contrast enhancement (CE) expands its diagnostic and imaging capabilities.

#3551 Endoscopic ultrasonography and elastography in pancreatic and gastrointestinal neuroendocrine tumors diagnostic

Introduction: Endoscopic ultrasonography (EUS) is an examination using ultrasound and an endoscopic device, designed to image digestive tract and adjacent organs. The combination of EUS and elastography (EG) expands diagnostic and imaging capabilities.

#3482 PANDORA-2 protocol - Intervention study to improve quality of life in patients with small (≤2 cm) non-functional pancreatic neuroendocrine tumors

Introduction: Current guidelines changed the treatment strategy for small (≤2cm) non-functioning pancreatic neuroendocrine tumors (NF-pNET) from tumor resection to an active surveillance strategy. The previous PANDORA-1 (2021) study showed excellent clinical outcomes after a median follow-up of 17 months, where 89% of patients had pNETs without any tumor growth and only 3% of patients had tumor growth leading to a resection. Despite these results, the quality of life (QoL) was decreased at baseline and during follow-up. Furthermore, there was suboptimal adherence to the advised surveillance protocol.
