neuroendocrine tumors/구역질

OBJECTIVE Small intestinal neuroendocrine tumours (SI-NETs) are derived from enterochromaffin cells. After demonstrating melatonin in enterochromaffin cells, we hypothesized that SI-NETs may express and secrete melatonin, which may have an impact on clinical factors and treatment

The coexistence of signet-ring cell carcinoma and neuroendocrine tumors is very rare. We report a 57-year-old man who presented with a history of weight loss and nausea. Gastric mucosal biopsies obtained during gastrointestinal endoscopy revealed a gastric signet-ring cell carcinoma. The patient

Neuroendocrine tumours of the colon and rectum are infrequent. Clinical manifestations are not different from standard adenocarcinoma. Symptoms are non specific; the most common are abdominal pain, nausea and vomiting, weight loss and gastrointestinal blood loss. We report an advanced case of

Pasireotide (SOM-230) is a small somatostatin (SST) analog that is being developed by Novartis Pharma AG for the potential treatment of acromegaly, Cushing's disease and neuroendocrine tumors; the compound is currently in phase III clinical trials for Cushing's disease. Pasireotide exhibits high

BACKGROUND Previous experiences in the treatment of neuroendocrine tumours have demonstrated some activity of single agents such as adriamycin, fluorouracil (FU), streptozotocin and dacarbazine (DTIC). Opinions concerning the usefulness of polychemotherapy in carcinoid tumours are discordant,

Metaiodobenzylguanidine (MIBG), radioiodinated with (131)I, has been available for 25 years. Its role in the United States is limited to diagnostic imaging, whereas its therapeutic application in patients with neuroendocrine tumors for whom surgical treatment would not lead to a cure, has been

Pancreatic neuroendocrine tumors (PNETs) are uncommon malignancies. The purpose of this study was to identify the prognostic factors of pancreatic neuroendocrine tumors at a single center in China. Clinical data of 27 patients with PNETs treated at the Sun Yat-sen University Cancer Center between

Neuroendocrine tumors (NETs) are neoplasms that arise from neural crest argyrophil cells, and often occur to the elderly, female and patients with cholelithiasis. In this case, the female patient was 38 years old and admitted into the hospital for interrupted right upward abdominal pain for 2 years

OBJECTIVE To review the clinical features associated with hyperglucagonemia in malignant neuroendocrine tumors. METHODS We retrospectively reviewed the medical records of patients with hyperglucagonemia encountered at our institution from Oct. 17, 1988, through February 1993 who had a fasting serum

Objectives: A prospective clinical trial evaluated the effect of Ga-DOTATOC positron emission tomography-computerized axial tomography (PET-CT) on change in management of patients with lung, pancreatic, and small bowel neuroendocrine

Gastroenteropancreatic (GEP) neuroendocrine tumors are rare neoplasm and have proved to be slow growing malignancies which involve many organs and most frequently the gastrointestinal tract. They have a peculiary biological behaviour: most of them have endocrine function (carcinoid syndrome); many

BACKGROUND High-administered activity In-111 octreotide (HA-Oc) therapy has been used for patients with disseminated neuroendocrine tumors (NET) with high somatostatin receptor (SSR) expression. Combining HA-Oc with radiosensitizing 5-fluorouracil (5FU) chemotherapy could enhance efficacy. Our other

Objective: To examine patients with metastatic gastroenteropancreatic neuroendocrine tumors (GEP-NETs) who receive sequential treatment with somatostatin analogs. Materials and Methods: This retrospective chart review examined lanreotide depot/autogel tolerability and efficacy among

CONCLUSIONS Rate of progression-free survival at a particular point in time, i.e., a landmark analysis, is a difficult endpoint for a heterogenous malignancy such as neuroendocrine cancer.Landmark analyses can also be complicated by evolution in the standard of care during the conduct of a clinical

OBJECTIVE To compare the effect of octreotide with f placebo on symptoms, tumour marker and quality of life in patients with gastrointestinal neuroendocrine tumours and liver metastases. METHODS A blinded, placebo-controlled, cross-over study was performed. The number of flushing epidodes and
