The incidence of neuroendocrine tumours of the gastroenteropancreatic system seems to have increased during the past decade. New diagnostic and therapeutic procedures have aroused the interest of physicians, though most see very few cases of such diseases. A group of members of the Nordic Neuroendocrine Tumour Group decided to compile some guidelines to facilitate the diagnosis and treatment of...
Functional imaging of neuroendocrine tumours with Octreoscan and I123-metaiodobenzylguanidine (MIBG) is important for assessment prior to various therapies and assessing response. The two imaging methods have not been directly compared in hepatic neuroendocrine tumours. Patients (n = 18) were studied with both imaging techniques. The sensitivity of Octreoscan was 94%, and that of MIBG 39%. No p...
I-131 MIBG scintigraphy is routinely used in the diagnosis of neuroendocrine tumours with high specificity. The radiopharmaceutical is taken up via uptake mechanism and actively transported into storage vesicules. The organs with dense sympathetic innervation such as salivary glands, heart, lachrymal glands, spleen and rarely adrenal medulla are normally visualized with I-131 MIBG. Asymetrical ...
Gastrointestinal neuroendocrine tumours are classified as functioning or non-functioning according to the presence or absence of a clinically evident hypersecretion syndrome. In foregut tumours the presence of autonomous hormone secretion and the respective hypersecretion syndrome indicate functionality. Abdominal ultrasound (US), computed tomography (CT), magnetic resonance tomography (MRT) an...
As incidence data on gastroenteropancreatic neuroendocrine tumours (GEP-NETs) have so far only been retrospectively obtained and based on inhomogeneous material, we conducted a prospective study in Austria collecting all newly diagnosed GEP-NETs during 1 year. Using the current WHO classification, the tumor, nodes, metastases (TNM) staging and Ki67 grading and the standard diagnostic procedure ...
The system of classification and terminology neuroendocrine neoplasms (NENs), updated in 2017 by AJCC 2019 WHO, is now recommended for general use. This article a review this with respect to NENs the digestive tract. Within new system, two categories were introduced, differing morphology, clinical course treatment, as based on differentiation histological maturity grading (G). Among tract, wel...
Nordic Guidelines 2010 for diagnosis and treatment of gastroenteropancreatic neuroendocrine tumours.
The diagnostic work-up and treatment of patients with neuroendocrine tumours has undergone a major change during the last decade. New diagnostic possibilities and treatment options have been developed. These Nordic guidelines, written by a group with a major interest in the subject, summarises our current view on how to diagnose and treat these patients. The guidelines are meant to be useful in...
