Progression-Free Survival (PFS) and Tumor Growth with Lanreotide Autogel (LAN) in Patients (Pts) with Enteropancreatic NETs: Results from CLARINET, a Randomized, Double-Blind, Placebo (Pbo)-Controlled Study Abstract #970

Introduction: Prospective data on antiproliferative effects of somatostatin analogs are lacking in grade 2 and non-midgut tumors.
Aim(s): CLARINET prospectively evaluated the antiproliferative activity of LAN in both intestinal and pancreatic NET (grade 1/2).
Materials and methods: CLARINET was a randomized, double-blind, Pbo-controlled study. Pts who had well/moderately differentiated, with Ki-67<10%, non-functioning enteropancreatic NETs, and no SSA or other medical therapy within last 6 mo, received LAN 120mg (n=101) or Pbo (n=103) every 4 wks for 96 wks or until PD/ death. Primary endpoint PFS and tumor response were evaluated based on centrally assessed CT scans.

#898 Evaluation of Tumor Response to Targeted Therapies in Precision-Cut Slices of Human Pancreatic Neuroendocrine Tumors
Introduction: Patients with PNET might benefit from new therapeutic approaches acting on the mTOR signaling pathway. Culture of precision-cut slices could allow testing these molecules in human tumors, allowing personalized treatments.

#62 Genome-wide DNA methylation profiling of pancreatic neuroendocrine tumors identifies distinct methylation profiles and differentially methylated gene promoter regions associated with low, medium and high grade tumors
Introduction: Integration of genetics and epigenetics has emerged as a powerful approach to studying cellular differentiation (Mikkelsen et al, 2009) and tumorigenesis (Shen et al, 2007). The study of DNA methylation is of particular importance in cancer, as causal involvement has been demonstrated and it is the most stable of all epigenetic modifications, making it a desirable marker for both early detection and treatment of tumors. Hypermethylation of CpG sites in gene promoter regions leads to decreased gene expression; if such a gene is a tumor suppressor, this leads to carcinogenesis. To date, there have been no studies of genome-wide DNA methylation profiling of NETs. This study sets out to determine the DNA methylation profiles of low, intermediate and high grade pancreatic NET liver metastases with the intention of identifying dysregulated biological pathways in the development of these tumors. A protocol for the analysis formalin-fixed paraffin embedded tissue (FFPE) has also been developed in order to study these tumors in significant numbers following this pilot study.
