Case Report of Recurrent VIPoma Abstract #1248

Introduction: 51yr presented with 7 month diarrhoea&2 stone weight loss. All tests negative, only abnormality hypokalaemia. FGH profile: VIP raised>400, peptide histidine methionine>1000, GAWK of 250. Diagnosis of VIPoma. CT: 5cm mass tail & body of pancreas, no hepatic or adrenal lesions. Octreotide treatment started. Bowel frequency improved, hypokalaemia corrected. Octreotide scan showed uptake only in pancreas. Patient readmitted 5 months later hypokalaemic myopathy, K 1.7, surgical distal pancreatectomy & splenectomy completed. Histology: NET within pancreas, moderate cellular differentiation, variable mitotic rate.
Aim(s): Tumour enclosed in capsule, showed capsular invasion. Patient discharged, followed-up 9yr, no signs of recurrence.
Materials and methods: 11yr on patient referred on cancer pathway with diarrhoea, no electrolyte changes. Colonoscopy: normal. CT: tumour recurrence in pancreatic bed. CgA120, CgB89, VIP130, other FGH normal. Ocreotide scan: uptake left upper quadrant & epigastrium. USS biopsy: NET minimal cellular differentiation, no evidence mitotic activity, positive chromogranin & synaptophysin, low Ki67 <5%.

#2955 Development of an EORTC Quality of Life Questionnaire for Patients with Pancreatic Neuroendocrine Tumours: Phases 1-3
Introduction: Measuring quality of life (QoL) in Pancreatic Neuroendocrine Tumours (pNET) involves assessing issues from symptoms, disease and treatment. The validated gastrointestinal NETs module (EORTC QLQ-GINET21) is used with EORTC QLQ-C30 but there are concerns it inadequately measures QoL in pNET.

#106 Gastroenteropancreatic neuroendocrine tumors: single institution clinicopathological study
Introduction: Neuroendocrine cells are widely distributed throughout the body, and neoplasms from these dispersed cells can arise at many sites. They are distinguished into two broad categories: 1) Tumors identified as small cell lung carcinomas with biology and natural history of a high-grade malignancy and characteristics of small cell undifferentiated or anaplastic appearance by light microscopy. The WHO categorizes these tumors as poorly-differentiated neuroendocrine carcinomas; 2) Well-defined neuroendocrine tumors (NETs) with variable, but most lyindolent biologic behavior and characteristic well-differentiated histologic features. The majority arise in the gastrointestinal tract and collectively they are referred as gastroenteropancreatic neuroendocrine tumors (GEP/NETs). They include carcinoid tumors, pancreatic islet cell tumors (gastrinoma, insulinoma, glucagonoma, VIPoma, somatostatinoma), paragangliomas, pheochromocytomas, and medullary thyroid carcinomas. The WHO classifies the GEP/NETs as well-differentiated NETs (carcinoid tumors) if they are noninvasive and have benign behavior or uncertain malignant potential. In contrast, GEP/NETs with characteristics of low-grade malignancy with invasion of the muscularis propria or beyond, or metastases, are characterized as well-differentiated neuroendocrine carcinomas (malignant carcinoids). Pancreatic islet cell tumors, whether functioning or not, are classified as well-differentiated NETs or well-differentiated neuroendocrine carcinomas, due to the (depending on) histologic characteristics. The WHO classification for gastroenteropancreatic NETs based on stage (ie size and presence of metastases) and grade (mitotic rate, perineural and lymphovascular invasion, Ki-67 proliferative index) categorizes them as well-differentiated NETs, e.g., carcinoid tumors, or as well-differentiated neuroendocrine carcinomas.

#134 Gastrointestinal neuroendocrine tumors: tumor characteristics and long-term clinical outcome in the German NET registry
Introduction: Prognosis of neuroendocrine tumors (NETs) has been difficult to predict due to heterogenous tumor biology, various classification systems, and lack of reliable and recent data due to the rarity of these tumors.
