Gastric hemangioma in the neonatal period is a very rare cause of upper gastrointestinal bleeding. We present a case of hemangioma limited to the gastric cavity in a 10-day-old infant. A huge, erythematous mass with bleeding was observed on the lesser curvature side of the upper part of the stomach. Surgical resection was ruled out because the location of the lesion was too close to the gastroesophageal junction. Medical treatment with intravenous H2 blockers, octreotide, packed red blood cell infusions, local epinephrine injection at the lesion site, application of hemoclip, and gel-form embolization of the left gastric artery did not significantly alter the transfusion requirement...

Synthetic somatostatin analogs have been posed as a potential source of error in somatostatin receptor imaging by interfering with tumor detection; however, experimental models and clinical studies have shown a complex mechanism of octreotide effect on tumors. This study aimed to assess whether (68)Ga-DOTATATE uptake differs before and after treatment with long-acting somatostatin analogs. Methods: Thirty patients with intermediate to well differentiated neuroendocrine tumors (NET) who underwent (68)Ga-DOTATATE Positron Emission Tomography/Computed Tomography (PET/CT) scanning before and after receiving long-acting repeatable (LAR) Sandostatin were included in the study...

BACKGROUND/PURPOSE: Somatostatin analogues are the cornerstone of systemic therapy for metastatic well-differentiated gastroenteropancreatic neuroendocrine tumours for both hormonal control and antiproliferative effect. Dose escalation of somatostatin analogues is often utilized in clinical practice, but small studies have yielded mixed results. The aim of this study was to systematically determine the efficacy and safety of escalated-dose somatostatin analogues in the above setting. METHODS: Eligible trials (using more than 30 mg octreotide or 120 mg lanreotide/28 days) were identified from MEDLINE, EMBASE, other databases and conference proceedings...

The granulation pattern of somatotroph adenomas is well known to be associated with differing clinical and biochemical characteristics, and it has been shown that sparsely granulated tumours respond poorly to commonly used somatostatin receptor ligands (SRLs). We report a challenging case of acromegaly with a sparsely granulated tumour resistant to multiple modalities of treatment, ultimately achieving biochemical control with pasireotide. A 26-year-old lady presented with classical features of acromegaly, which was confirmed by an oral glucose tolerance test...

Postoperative chylous fistula after neck dissection is an uncommon complication associated with significant patient morbidity. Octreotide acetate is a somatostatin analogue established in the treatment of chylothorax; however, its utility in the management of cervical chylous fistulae has not been fully evaluated. The investigators hypothesized that chylous fistula can be managed by a combination of octreotide and peripheral total parenteral nutrition (TPN). A retrospective review of cases compiled at our institution from 2009 to 2015 was conducted...

INTRODUCTION: Between 2009 and 2012, (68) Ga-somatostatin analogue PET-CT progressively replaced (111) In-octreotide scintigraphy for imaging neuroendocrine tumours in WA public hospitals due to published literature demonstrating improved diagnostic accuracy and increased availability. Despite significantly improved sensitivity and specificity, (68) Ga-somatostatin analogue PET is currently unfunded in Australia. This study sought to undertake cost analysis of the two modalities in a public hospital setting and to compare them with regard to patient factors such as imaging time and radiation dose...

Octreotide, a long-acting somatostatin analog, has been used for treating hypoglycemia caused by congenital hyperinsulinism (CHI). However, octreotide has not been evaluated in clinical trials and has not been approved in any developed country. We aimed to test the efficacy and safety of octreotide for diazoxide-unresponsive CHI through a combination of a single-arm, open-label clinical trial (SCORCH study) and an observational study to collect data on the clinical course of patients treated off-label in Japan (SCORCH registry)...

Despite all technical progress in modern diagnostic methods and treatment modalities of pheochromocytoma/paraganglioma, early consideration of the presence of these tumors remains the pivotal link towards the best possible outcome for patients. A timely diagnosis and proper treatment can prevent the wide variety of potentially catastrophic cardiovascular complications. Modern biochemical testing should include tests that offer the best available diagnostic performance, measurements of metanephrines and 3-methoxytyramine in plasma or urine...

Neuroendocrine tumors (NETs) consist of a diverse family of malignancies, which are derived from neuroendocrine cells, most commonly originating from the gastroenteropancreatic (GEP) tract or the bronchopulmonary system. In general, NETs are more indolent than epithelial tumors, with median survival rates of longer than 30 months. The upregulation of mTOR pathway has been shown to play a pivotal role in NET pathogenesis. Inhibition of mTOR protein with everolimus represents a progress in the treatment of advanced NETs...

Molecular imaging of tumors with the PET radionuclide (68)Ga has gained momentum in clinical oncology due to the expanding availability of commercial (68)Ge/(68)Ga-generators in combination with state-of-the-art PET/CT and PET/MRI hybrid imaging systems. Concurrently, interesting peptide-based or small-size vectors have been developed for theranostic use in cancer patients. Owing to the short half-life of (68)Ga (t1/2 = 67.7 min) and the sensitivity of many targeting biomolecules, labeling and kit reconstitution in mild conditions allowing for quick access to ready-for-injection PET-tracers are highly desirable...

Chylous ascites is an uncommon clinical entity, which usually results from congenital or acquired abnormality in proper lymphatic flow. While the common causes are related to trauma, malignancy or tuberculosis, pancreatic disorders can occasionally result in chylous ascites. Sporadic cases of chylous ascites due to acute or chronic pancreatitis or surgery for pancreatitis have been reported. The usual management is with medium chain triglycerides (MCT), total parenteral nutrition and octreotide. We report a case of a young male with idiopathic chronic pancreatitis who presented with chylous ascites which did not respond to MCT based diet and octreotide...
