#4645 Radio-guided surgery in use for treatment of early relapse in small intestine neuroendocrine tumours

Introduction: Surgery is the only definitive therapy for neuroendocrine tumours (NET). In number of small intestine NET first symptom is ileus or perforation, lifesaving surgical procedures applied. Such cases have significant risk of recurrence.

#4187 Psychiatric and cognitive function in patients with serotonin producing neuroendocrine tumors

Introduction: Cognitive and psychiatric problems are common in cancer patients, but literature in patients with neuroendocrine tumors (NET) is scarce. Peripheral serotonin overproduction by the tumor, clinically manifesting as carcinoid syndrome, is hypothesized to be related to cognitive and psychiatric problems, through depletion of serotonin’s precursor tryptophan.

#3752 Loss of protein expression of tumor suppressor genes in neuroendocrine tumors – A tissue microarray analysis of 201 tumors from various organ sites

Introduction: Neuroendocrine tumors (NET) are a heterogenous group of tumors which differ in outcome based on their primary site. So far, data on inactivation of tumor suppressor genes in NET are mainly based on pancreatic and small intestine NET (pNET, siNET), whereas NET from other organ sites have not rigorously been analysed.
