- Neuroendocrine tumors of the small intestine are the most common causes of the carcinoid syndrome. Carcinoid heart disease occurs in more than half of the patients with the carcinoid syndrome. Patients with carcinoid heart disease who need to undergo surgery should also undergo preoperative evaluation by an expert cardiologist. Treatment with longacting somatostatin analogs aims at controlling the excessive hormonal output and symptoms related to the carcinoid syndrome and at preventing a carcinoid crisis during interventions. Patients with a gastrinoma require pre- and postoperative treatment with high doses of proton pump inhibitors. Patients with a glucagonoma require somatostatin analog treatment and nutritional supplementation. Patients with a VIPoma also require somatostatin analog treatment and intravenous fluid and electrolyte therapy. Insulinoma patients generally require intravenous glucose infusion prior to operation. In patients with localized operable insulinoma, somatostatin analog infusion should only be considered after the effect of this therapy has been electively studied.

- Guidelines recommend adults with pituitary disease in whom GH therapy is contemplated, to be tested for GH deficiency (AGHD); however, clinical practice is not uniform.1) To record current practice of AGHD management throughout Europe and benchmark it against guidelines; 2) To evaluate educational status of healthcare professionals about AGHD.On-line survey in endocrine centres throughout Europe.Endocrinologists voluntarily completed an electronic questionnaire regarding AGHD patients diagnosed or treated in 2017-2018.Twenty-eight centres from 17 European countries participated, including 2139 AGHD patients, 28% of childhood-onset GHD. Aetiology was most frequently non-functioning pituitary adenoma (26%), craniopharyngioma (13%) and genetic/congenital mid-line malformations (13%). Diagnosis of GHD was confirmed by a stimulation test in 52% (GHRH+arginine, 45%; insulin-tolerance, 42%, glucagon, 6%; GHRH alone and clonidine tests, 7%); in the remaining, ≥3 pituitary deficiencies and low serum IGF-I were diagnostic. Initial GH dose was lower in older patients, but only women <26 years were prescribed a higher dose than men; dose titration was based on normal serum IGF-I, tolerance and side-effects. In one country, AGHD treatment was not approved. Full public reimbursement was not available in four countries and only in childhood-onset GHD in another. AGHD awareness was low among non-endocrine professionals and healthcare administrators. Postgraduate AGHD curriculum training deserves being improved.Despite guideline recommendations, GH replacement in AGHD is still not available or reimbursed in all European countries. Knowledge among professionals and health administrators needs improvement to optimize care of adults with GHD.

- Purpose: Octreotide SC depot is a novel, ready-to-use formulation administered via a thin needle. In a phase 1 study in healthy volunteers, this formulation provided higher bioavailability of octreotide with faster onset and stronger suppression of IGF-1 in healthy volunteers versus long-acting intramuscular (IM) octreotide. This phase 2 study evaluated the pharmacokinetics, efficacy, and safety of octreotide SC depot in patients with acromegaly and functioning NETs, previously treated with octreotide IM. Methods: Adult patients with acromegaly or functioning NETs treated for ≥ 2 months with octreotide IM [10/20/30 mg every 4 weeks (q4w)] received the last dose of octreotide IM treatment in study period 0 and were randomized 28 days later to receive octreotide SC depot 10 mg q2w, or 20 mg q4w for 3 months (period 1). The primary objective was to characterize the PK profile of octreotide SC depot after each injection vs PK for octreotide IM (period 0). Results: Twelve patients were randomized to receive octreotide SC depot 10 mg q2w (acromegaly n = 3; NET n = 1) or 20 mg q4w (acromegaly n = 4; NET n = 4). Plasma levels of octreotide were higher with octreotide SC depot as compared to octreotide IM. Adverse events were reported in 6 and 8 patients during period 0 and period 1, respectively; most common in period 1 were gastrointestinal disorders. Conclusion: Octreotide SC depot provided higher exposure (AUC) than octreotide IM, maintained biochemical control in patients with acromegaly and symptom control in patients with functioning NETs, and was well tolerated with a safety profile consistent with octreotide IM. ClinicalTrials.gov identifier: NCT02299089.

Forskningsöversikt (refereegranskat)abstract
- Neuroendocrine neoplasms (NENs) are a heterogeneous family of uncommon tumours with challenging diagnosis, clinical management and unique needs that almost always requires a multidisciplinary approach. In the absence of guidance from the scientific literature, along with the rapidly changing data available on the effect of COVID-19, we report how 12 high-volume NEN centres of expertise in 10 countries at different stages of the evolving COVID-19 global pandemic along with members of international neuroendocrine cancer patient societies have suggested to preserve high standards of care for patients with NENs. We review the multidisciplinary management of neuroendocrine neoplasms during the COVID-19 pandemic, and we suggest potential strategies to reduce risk and aid multidisciplinary treatment decision-making. By sharing our joint experiences, we aim to generate recommendations for proceeding to other institutions facing the same challenges. (C) 2020 Elsevier Ltd. All rights reserved.

ENETS Consensus Guidelines for the Standards of Care in Neuroendocrine Tumors : Biochemical Markers

- Biomarkers have been the mainstay in the diagnosis and follow-up of patients with neuroendocrine tumors (NETs) over the last few decades. In the beginning, secretory products from a variety of subtypes of NETs were regarded as biomarkers to follow during diagnosis and treatment: serotonin for small intestinal (SI) NETs, and gastrin and insulin for pancreatic NETs. However, it became evident that a large number of NETs were so-called nonfunctioning tumors without secreting substances that caused hormone-related symptoms. Therefore, it was necessary to develop so-called "general tumor markers." The most important ones so far have been chromogranin A and neuron-specific enolase (NSE). Chromogranin A is the most important general biomarker for most NETs with a sensitivity and specificity somewhere between 60 and 90%. NSE has been a relevant biomarker for patients with high-grade tumors, particularly lung and gastrointestinal tract tumors. Serotonin and the breakdown product urinary 5-hydroxyindoleacetic acid (U-5-HIAA) is still an important marker for diagnosing and follow-up of SI NETs. Recently, 5-HIAA in plasma has been analyzed by highperformance liquid chromatography and fluorometric detection and has shown good agreement with U-5-HIAA anal ysis. In the future, we will see new tests including circulating tumor cells, circulating DNA and mRNA. Recently, a NET test has been developed analyzing gene transcripts in circulating blood. Preliminary data indicate high sensitivity and specificity for NETs. However, its precise role has to be validated in prospective randomized controlled trials which are ongoing right now.
