#2817 METNET: A Phase II Trial of Metformin in Patients with Well Differentiated Neuroendocrine Tumors

Introduction: Preclinical studies have suggested that metformin has antitumor effects, likely due to blockage of mTOR pathway through AMPK and decreased insulin levels. A retrospective study showed that metformin combined with everolimus to treat related hyperglycemia offered longer progression-free survival (PFS) in patients (pts) with pancreatic neuroendocrine tumors (NET).

#2001 The Anticancer Mechanism of Metformin in Pancreatic Neuroendocrine Tumor Cells

Introduction: Metformin, a widely used antidiabetic drug, has been reported to display potent anticancer properties in various types of cancers. In P-NETs, aryl hydrocarbon receptor-interacting protein (AIP) acts as a tumor suppressor and is up-regulated by the somatostatin analog octreotide.

#1725 Safety of Lanreotide 120 mg ATG (LAN) in Combination with Metformin (MET) in Patients (pts) with Progressive Advanced Well-Differentiated (WD) Gastro-Intestinal (GI) or Lung Carcinoids. A Pilot, One-Arm, Open-Label, Prospective Study: The MetNET-2 Trial

Introduction: Anti proliferative effect of LAN ATG 120 mg has been investigated in 204 GI-NET pts in Clarinet study with a 53% reduction in risk of death/progression vs placebo. An increasing number of trials have associated MET with better outcome in cancer pts due to a reduction of insulin/IGF1 levels and modulation of AMPK and TSC1-2/mTOR. The retrospective PRIME-net study conducted on 445 Italian pts, suggest that addition of MET to everolimus and/or SSA provides clinical benefit in diabetic pancreatic NETs.

#1153 Prognostic Role of Diabetes Mellitus (DM) and Metformin (MET) Therapy in Patients (pts) with Advanced G1-G2 Neuroendocrine Tumors (NETs) Treated with Everolimus (EVE)

Introduction: MET has shown antitumorigenic effects on DM cancer pts, which are mediated by decrease of insulin/IGF-1 levels and activation of the AMPK pathway leading to mTOR inactivation.

#904 Role of Metformin on Recurrence-Free Survival (RFS) in Neuroendocrine Tumors (NET)

Introduction: Recent data suggest metformin (Met) has antineoplastic properties in different type of cancer. Effects of Met have never been investigated in NET.
