Although there are reports of goblet cell carcinoid(GCC)treated by chemotherapy using the treatment protocol for colon cancer, the benefit of chemotherapy for GCC remains controversial and unclear. Herein we report 2 cases of patients with GCC who were successfully treated by surgical resection and oxaliplatin-based adjuvant chemotherapy, without evidence of recurrence. The first case was a 57-year-old man who underwent laparoscopic ileocecal resection after being diagnosed with adenocarcinoma of the appendix by biopsy via colonoscopy. Read More

Goblet cell carcinoids (GCC) are extremelyrare neuroendocrine tumours, and characterised by their unique combination of two types of cancer cells âÃÂ" neuroendocrine (carcinoid) and epithelial (adeno-carcinoma). In spite of the fact that GCC is regarded as Neuro-Endocrine Tumour (NET), it does not illicit carcinoid syndrome. GCC usually arises in the appendix and accounting for less than 14% of all appendiceal tumours. Read More

Somatostatin analogs are an invaluable therapeutic option in the diagnosis and treatment of somatotropinomas, thyrotropinomas, and functioning and non-functioning gastroenteropancreatic neuroendocrine tumors. They should also be considered an effective and safe therapeutic alternative to corticotropinomas, gonadotropinomas, and prolactinomas resistant to dopamine agonists. Somatostatin analogs have also shown to be useful in the treatment of other endocrine diseases (congenital hyperinsulinism, Graves' orbitopathy, diabetic retinopathy, diabetic macular edema), non-endocrine tumors (breast, colon, prostate, lung, and hepatocellular), and digestive diseases (chronic refractory diarrhea, hepatorenal polycystosis, gastrointestinal hemorrhage, dumping syndrome, and intestinal fistula).

The pathological features of the appendix tumors fundamentally recall those of the more frequent colorectal neoplasms, although with a higher relative incidence of carcinoids, due to the abundant presence of enteroendocrine cells in the appendix wall. Moreover, different types of lymphomas, Hodgkin and non-Hodgkin, arising from the extra-nodal mucosal-associated lymphatic tissue, can be encountered. The appendix tumor microenvironment (TME) consists of a cellular component and of a noncellular component: the former includes the immunocompetent cells, while the latter represents the support stroma.

Rationale: Peptide receptor radionuclide therapy (PRRT) with radiolabeled somatostatin analogs is a targeted internal radiotherapy method used to treat tumors expressing somatostatin receptors. Concomitant amino acids perfusion is systematically performed in order to inhibit the proximal tubular uptake of the radionuclide and thus prevent nephrotoxicity.

: Well-differentiated gastroenteropancreatic (GEP) neuroendocrine tumors (NETs) are a heterogeneous group of neoplasms with a wide range of clinical behavior. Multiple treatment modalities exist, including novel and emerging systemic options, and an understanding of the advantages and disadvantages of each is imperative for optimizing the outcomes of patients with GEP-NETs.: While surgical resection remains the preferred treatment for localized well-differentiated GEP-NETs, treatment of unresectable disease depends on its extent, location, and distribution as well as underlying aspects of tumor biology.

Current guidelines have been published for the diagnosis and therapy of neuroendocrine neoplasms of the gastroenteropancreatic (GEP) system 1. Systemic therapy of inoperable advanced neuroendocrine tumors includes biotherapy with somatostatin analogas, peptid receptor radionuclide therapy (PRRT) with 177Lutetium-DOTA-TATE, chemotherapy with steptozotocin/5-fluorouracil or capecitabine/temozolomide and molecular targeted therapy with everolimus or sunitinib 1 2. For symptom control in patients with carcinoid syndrome biotherapy with somatostatin analogs, PRRT, loco-regional and local-ablative interventional procedures of liver metastases as well as the peripheral serotonin synthesis inhibitor telotristat Ethyl 1 2 3 4 are highly effective.

Background: Small intestinal neuroendocrine tumors are the most common of small bowel malignancies with a clinical incidence of about 1 per 100,000 persons per year. There has been a threefold increase in the incidence of small intestinal neuroendocrine tumor during later decades, but there are no studies that clarify whether this is due to a true higher incidence or if the rise is a mere product of, for instance, improved diagnostic modalities. The aim of this study was to investigate the incidence of clinical as well as subclinical small intestinal neuroendocrine tumors found at autopsy as well as describing the frequency of concomitant malignancies in patients with small intestinal neuroendocrine tumor.

In recent decades, the incidence of neuroendocrine tumors (NETs) has steadily increased. Due to the slow-growing nature of these tumors and the lack of early symptoms, most cases are diagnosed at advanced stages, when curative treatment options are no longer available. Prognosis and survival of patients with NETs are determined by the location of the primary lesion, biochemical functional status, differentiation, initial staging, and response to treatment.

Background: Local endoscopic resection is an effective method for the treatment of small rectal carcinoid tumors, but remnant tumor at the margin after resection remains to be an issue.

Aim: To evaluate the efficacy and safety of resection of small rectal carcinoid tumors by endoloop ligation after cap-endoscopic mucosal resection (LC-EMR) using a transparent cap.

Carcinoid tumours have the ability to secrete various peptides and bioamines that lead to carcinoid syndrome manifested as cutaneous flushing, diarrhoea, bronchial constriction and cardiac involvement. The deficiencies of vitamins D and B have previously been reported in patients with carcinoid tumours presumably due to chronic diarrhoea associated with the carcinoid syndrome. Herein, we chronicle the case of a patient with opioid use disorder who presented with small bowel obstruction that was found to be caused by a midgut carcinoid tumour. Read More

Small bowel malignancies are extremely rare. Surgical resection is often the mainstay of treatment with the extent of the operation depending on the type of tumor. Whereas neuroendocrine tumors and adenocarcinoma require lymph node resection, gastrointestinal stromal tumors do not typically metastasize to regional nodes and therefore need resection only.

Gastroenteropancreatic neuroendocrine tumors are relatively rare neoplasms, characterized by a propensity to secrete hormones that cause distinct clinical syndromes. During the past decade, the systemic treatment landscape has improved significantly: new options include everolimus, an inhibitor of the mammalian target of rapamycin; sunitinib, an angiogenesis inhibitor; and cytotoxic regimens such as capecitabine and temozolomide. Moreover, the recent approval of the radiolabeled somatostatin analog Lu-DOTATATE has had a significant impact on management of neuroendocrine malignancies. Read More

Goblet cell carcinoid (GCC) or goblet cell carcinoma is a unique mixed endocrine-exocrine neoplasm that is almost exclusively seen in the appendix. The hallmark of GCC is the concentric infiltration of the appendiceal wall by small tight clusters, nests or cords of tumor cells that exhibit a goblet cell morphology with a small compressed nucleus and conspicuous intracytoplasmic mucin. The coexistence of high-grade adenocarcinoma with GCC has been increasingly recognized as a common finding, which has been called adenocarcinoma ex GCC or mixed GCC-adenocarcinoma. Read More

Introduction: Lanreotide autogel is a synthetic somatostatin analogue which has been FDA and EMA approved for unresectable, well to moderately differentiated, locally advanced or metastatic gastroenteropancreatic neuroendocrine tumor. Its action is mediated by its affinity to somatostatin receptors, especially sst2 and sst5 receptors. Its longer half-life offers the convenience of 4-week dosing over the need for frequent injections of short-acting somatostatin analogues. Read More
