BACKGROUND & AIMS: Metformin seems to have anti-cancer effects. However, it is not clear whether use of glycemia and metformin affect outcomes of patients with advanced pancreatic neuroendocrine tumors (pNETs). We investigated the association between glycemia and progression-free survival (PFS) of patients with NETs treated with everolimus and/or somatostatin analogues, as well as the association between metformin use and PFS time. METHODS: We performed a retrospective analysis of 445 patients with advanced pNET treated at 24 medical centers in Italy, from 1999 through 2015...

Somatostatin analogs have an important role in the medical therapy of neuroendocrine tumors (NETs). Octreotide and lanreotide, both somatostatin analogs binding with high affinity for the somatostatin receptor (SSTR)2, can control symptoms in functional NETs. In addition, these compounds, because of their antiproliferative effects, can stabilize growth of well-differentiated NETs. Pasireotide is a novel multireceptor-targeted somatostatin analog with high affinity for SSTR1, 2, 3, and 5. This review provides an overview of the state of the art of pasireotide in the treatment of NETs, with the aim of addressing clinical relevance and future perspectives for this molecule in the management of NETs...

Introduction: Somatostatin analogs (SSAs) effectivelycontrol growth hormone secretion in first and second line treatmentof acromegaly. Their effect onglucose metabolism is still debated. Aim: to address the following questions: 1) Do SSAs affect fasting plasma glucose (FPG), fasting plasma insulin (FPI), glycosylated hemoglobin (HbA1c), glucose load (2h-OGTT), HOMA-I, HOMA-β, triglycerides (TGD), weight (W) or body mass index (BMI)? 2) Do lanreotide (LAN) and octreotide LAR (OCT) affect metabolism differently? 3)Does their effect depend on disease control? Methods: We performed a meta-analysis of prospective interventional trialstreating acromegaly with SSAs...

Surgery is considered the treatment of choice in acromegaly, but patients with persistent disease after surgery or in whom surgery cannot be considered require medical therapy. Somatostatin receptor ligands (SRLs) octreotide (OCT), lanreotide, and the more recently approved pasireotide, characterized by a broader receptor ligand binding profile, are considered the mainstay in the medical management of acromegaly. However, in the attempt to offer a more efficacious and better tolerated medical approach, recent research has been aimed to override some limitations related to the use of currently approved drugs and novel SRLs therapies, with potential attractive features, have been proposed...

OBJECTIVE: Neuroendocrine tumors (NETs) are being seen increasingly frequently, and recent data show that long-acting somatostatin analogues have become a major initial treatment, regardless of whether the tumors are functioning or not. However, test dosing with subcutaneous (sc) octreotide is usually advised to assess longer-term tolerability, although this advice is mainly based on results with functioning tumors. The aim of the study was to assess the value of an initiating test dose of sc octreotide on the prediction of subsequent adverse events after treatment with the long-acting analogue...

The antiproliferative treatment options for neuroendocrine tumors (NET)/neuroendocrine carcinomas of the gastrointestinal tract critically depend on the proliferation rate, evaluated by immunohistochemical staining for Ki-67. According to their grading, tumors are treated with somatostatin analogs, mTOR inhibitors, or cytotoxic substances. This case illustrates downgrading of a primarily highly proliferative NET achieved by a variation of cytotoxic chemotherapy regimens, followed by a combination therapy using everolimus together with lanreotide...

Gastrinomas are functionally active pancreatic neuroendocrine tumors (NETs) secreting gastrin and are associated with local or regional metastases in 60% of the cases. Somatostatin analogs (SSAs) are currently recommended as a first-line treatment for the symptomatic treatment of NETs. Although antiproliferative activity of SSAs has been demonstrated in various cancer types in several in vivo and in vitro studies, clinical benefits with SSAs have been only achieved in a small proportion of patients. We report a disease control on a long-acting SSA lanreotide in a patient with metastatic gastrinoma...

PURPOSE: In clinical research involving acromegalic patients naïve to somatostatin-receptor ligands (SRLs), 19 and 31% of those receiving the SRLs octreotide LAR and pasireotide LAR, respectively, achieved GH < 2.5 ng/mL + normalized IGF-1 concentrations. The proportions achieving control appeared higher in the post-surgery compared with the de-novo setting with pasireotide, but more similar with octreotide. Using pooled data from multicenter clinical trials, we examined the biochemical efficacy of lanreotide depot/Autogel in similar settings...

Lung neuroendocrine tumors (NETs) comprise typical (TC) and atypical carcinoids (AC). They represent the well differentiated (WD) or low/intermediate grade forms of lung neuroendocrine neoplasms (NENs). Unlike the lung poorly differentiated NENs, that are usually treated with chemotherapy, lung NETs can be managed with several different therapies, making a multidisciplinary interaction a key point. We critically discussed the multimodal clinical management of patients with advanced lung NETs. Provided that no therapeutic algorithm has been validate so far, each clinical case should be discussed within a NEN-dedicated multidisciplinary team...

Gastroenteropancreatic neuroendocrine tumors (GEP-NETs) are a large and very diverse group of neoplasms. Clinical presentation of NETs depends on the site of the primary tumor and whether the tumor is functioning (i.e., secreting peptides or neuroamines that produce symptoms). The diagnosis of GEP-NET is further complicated by symptomatic differences that occur depending on the type of secreted peptide or neuroamine. Due to their heterogeneity and unique characteristics, early diagnosis of GEP-NETs is difficult, which increases the likelihood of metastatic disease and reduces the scope of therapeutic possibilities...

A 14 amino acid cystin bridge containing neuropeptide was discovered in 1973 and designated as growth hormone-inhibiting hormone, in other words, somatostatin. Its discovery led to the synthesis of three analogs which were licensed for the treatment of acromegaly: octreotide, lanreotide and pasireotide. Somatostatin analogs are currently approved only as either subcutaneous or intramuscular long-acting injections. We examine the challenges that must be overcome to create oral formulations of somatostatin analogs and examine selected clinical trial data...

Neuroendocrine tumors (NETs) are a relatively rare and heterogeneous group of neoplasms with an annual incidence of ~35 cases per 100,000 people in the United States. The updated World Health Organization (WHO) classification system of gastroenteropancreatic (GEP)-NETs categorizes these tumors according to site of origin, clinical syndrome, and degree of differentiation. Well-differentiated NETs arising from the gastrointestinal tract or lungs (formerly known as carcinoid tumors) are often indolent and slow-growing...

Neuroendocrine tumors (NETs) of the lung are divided into 4 major types: small cell lung cancer (SCLC), large cell neuroendocrine carcinoma (LCNEC), atypical carcinoid (AC) or typical carcinoid (TC). Each classification has distinctly different treatment paradigms, making an accurate initial diagnosis essential. The inconsistent clinical presentation of this disease, however, makes this difficult. The objective of this manuscript is to detail the diagnosis and management of the well differentiated pulmonary carcinoid (PC) tumors...
