#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.

#546 Treatment of Malignant Neuroendocrine Tumors of the Hepatopancreatododenal Region
Introduction: The incidence of malignant NETs of the hepatopancreatoduodenal region is currently set at 10-15 cases per 100,000 people. Patient treatment and prognosis differ from those with adenocarcinoma.

#646 Immunohistochemical (IHC) and Cytogenetic Approach for Improving Diagnosis and Therapy of Ewing Sarcoma (ES)/pPNET Arising in the Ileocecal Region
Introduction: ES/pPNET primary to the ileocecal region (IpPNET) have been rarely reported on and show close similarities in histology and clinical presentation with small round blue cell tumors. The EWS gene is fused to four members of the ETS family.

#1896 Launching NETwerk: Diagnosis and Treatment of Neuroendocrine Tumors within a Multi-Institutional Collaboration in the Region of Antwerp-Waasland in Belgium
Introduction: Centralizing cancer services is one way to improve global outcome for cancer patients but brings along that patients must be motivated to travel and that doctors of local hospitals get deprived of the diagnostic and treatment skills. The alternative way is to centrally coordinate cancer services across different hospitals. In this scenario, local multidisciplinary teams refer all patients to be discussed among cancer specialists. This continuous feed-back system also creates the opportunity to propose additional more specific and sensitive examinations for individual patients which would introduce the end of local substandard treatment.

#232 Prognostic Factors and Survival in 481 Patients with Pancreatic and Peripancreatic Endocrine Tumors: Results from the National Cancer Registry of Spain (RGETNE)
Introduction: Duodenopancreatic neuroendocrine tumors (NETs) are uncommon neoplasms with a wide spectrum of clinical presentation. The infrequent occurrence of these tumors makes large experiences very scarce.

#248 Difficulties in Differential Diagnostics of Neuroendocrine Tumors
Introduction: Primary neuroendocrine tumors (NET) of soft tissues and soft tissue metastases are seen rarely and need differentiation from other types of tumors (as chemodecroma or paraganglioma).

#1098 177Lu Dotatate vs Sequential 177Lu Dotatate and 90Y Dotatate: Treatment Outcomes for PRRT Patients at the Christie - A Clinical Audit
Introduction: The traditional treatment regime of somatostatin receptor positive NETs by molecular radiotherapy was based on single radionuclides (e.g. 90Y Dotatate or 177Lu Dotatate), delivered as multiple cycles to allow normal tissue recovery. However a newer practice of alternating tcycles of 177Lu and Y90 Dotatate was implemented at the Christie following introduction of this regime in some European centres. Subsequent follow up studies have indicated that longer overall survival and reduced loss of kidney function is found in patient cohorts treated with combined 177Lu and 90Y regimes to either 177Lu or 90Y alone.

#1100 Cyclin-Dependent Kinase Inhibitor 2A (CDKN2A/P16) Polymorphisms and Risk of Pancreatic Neuroendocrine Tumors
Introduction: Pancreatic neuroendocrine tumors (PNETs) represent only 1% of all pancreatic neoplasms by incidence, but 10% by prevalence. Family history of cancer is the only established risk factor so far. The impact of germline genetic variability on PNET risk is poorly understood.

#65 Deletions of 11q21-q25 are associated with atypical lung carcinoids and a poor clinical outcome
Introduction: Lung carcinoids comprise a group of smoking-unrelated neuroendocrine tumors, which can be classified in typical (TC) and atypical (AC) carcinoids. Classification is complex and its accuracy to predict disease outcome is variable. In a previous array comparative genomic hybridization (arrayCGH) study, we showed that the average number of chromosomal alterations (≥ 1Mb) was significantly higher in ACs than in TCs (512 v. 226 per tumor) and that the most common region of chromosome loss was 11q21-q25 (Neuroendocrinology 2009;90:136-137).
