#3031 Primitive Peripheral Neuroectodermal Tumor: Case Report

Introduction: Primitive neuroectodermal tumors belong to the family of Ewing sarcomatous tumors, all derived from the same stem cell. The cells of the neural crest are believed to be at the origin of these tumors. The predilection sites of these sarcomas are para-vertebral region, chest wall and the distal ends. The positive diagnosis of primary neuroectodermal tumors requires the contribution of histopathology, immunohistochemistry and cytogenetics.

#2869 Sunitinib in Combination with Lanreotide for the Treatment of Pancreatic Neuroendocrine Tumors

Introduction: A 33-year-old patient with pancreatic neuroendocrine tumor (NET) G2 revealed progression of the disease in the form of multiple metastases to the liver, lymph nodes of the hepatoduodenal ligament and retroperitoneal space 1.5 months after surgical treatment.

#2739 Epigenetic Landscape of Pancreatic Neuro-Endocrine Tumors Reveals Distinct Cells of Origin and Means of Tumor Progression

Introduction: Pancreatic Neuroendocrine Tumors (PanNETs) arise from cells of the Islets of Langerhans. The majority of PanNETs are non-functional and their cell of origin cannot be defined analysing specific hormone production. Cell of origin assessment has proven importance to identify risk factors, prevent tumour development, and tailor treatment in many malignancies. Recent data on super-enhancer signatures has suggested a potential origin of PanNET from α- or β-cells. We and others have shown that distinct epigenetic profiles assessed by DNA methylation (DNAme) characterize genomic and prognostic groups of PanNET.

#2171 A Matched-Pair Analysis of Conventional Surgical Methods versus Enucleation for Pancreatic Neuroendocrine Tumors

Introduction: Pancreatoduodenectomy and distal pancreatectomy are still main therapy for pancreatic neuroendocrine tumours (pNETs).Recently enucleation has also been increasingly used to treat pNETs.
