A Novel In Vitro Model of a Highly Proliferative Pancreatic Neuroendocrine Neoplasia Abstract #1553

Introduction: Transformation of well-differentiated neuroendocrine tumors into highly proliferative neuroendocrine neoplasms is a rare, but clinical relevant phenomenon. So far, it is unclear whether these tumors should be treated in analogy to neuroendocrine tumors or as bona fide neuroendocrine carcinoma.
Aim(s): To develope a new in vitro model to study treatment responses in tumor cells.
Materials and methods: We here report the establishment of a pair of neuroendocrine cell lines from the primary site and and from a liver metastasis of a patient with a neuroendocrine neoplasm. The patient was initially diagnosed with a G2 pancreatic neuroendocrine tumor. After several lines of treatment the tumor eventually transformed into a G3 (Ki-67 60%) neuroendocrine neoplasm.

#1183 Establishment of a New Human Pancreatic Neuroendocrine Tumour Cell Line
Introduction: The development of new therapeutic strategies for patients with pancreatic neuroendocrine tumours is impaired by the paucity of suitable pre-clinical models. Although the two available tumour cell lines BON and QGP have a neuroendocrine phenotype, the proliferation rate is too high for a well differentiated neuroendocrine tumour.

#1573 Regulation of Neuroendocrine Differentiation by Growth Factor Induced Proliferation in a Well-differentiated Pancreatic Neuroendocrine Tumor Cell Line
Introduction: The regulation of neuroendocrine differentiation in NET tumor cells is poorly understood. Clinical experience suggests a correlation between proliferation and neuroendocrine de-differentiation.

#1528 Medullary Thyroid Carcinoma Cell Lines – An Update
Introduction: Medullary Thyroid Carcinoma (MTC) originates from calcitonin-producing neuroendocrine C-cells of the thyroid gland. Mutations in the RET-proto-oncogene are associated with both sporadic and familial MTC. As MTC are poorly responsive to chemo- and radiation- therapy, surgery is the only curative treatment at the moment. The cytogenetics of MTC have been sparsely investigated because the cells are very difficult to cultivate. In the last three decades our research group has established 10 continues cell lines derived from primary tumor and lymph node metastasis of patients with either sporadic or hereditary MTC.

#1115 Cancer Stem Cells in Small Intestine Neuroendocrine Cell Line P-STS: Isolation and Molecular Characterisation
Introduction: Cancer stem cells (CSCs) represent a small subpopulation of tumour cells responsible for invasive tumour growth. Even though the presence of CSCs in neuroendocrine tumours is documented, their role in neuroendocrine tumourigenesis and metastasis is not defined as yet.

#1867 Establishment of the First Well-Differentiated in Vivo Human Pancreatic Neuroendocrine Tumor Model
Introduction: The development of new therapeutic strategies for cancer patients relies on the in vitro and in vivo testing of novel substances in the pre-clinical setting. So far, this has not been possible for pancreatic neuroendocrine tumors (pNET) due to lack of suitable animal models resembling the disease course in human patients.
