#88 EpCam expression and detection of circulating tumor cells in neuroendocrine tumors
Introduction: Using the CellSearchTM system, circulating tumor cells (CTCs) can be reproducibly enumerated according to expression of EpCAM and cytokeratins 8, 18 or 19 and the absence of the haemopoietic marker CD45. The number of CTCs detected in 7.5 mls blood has been shown to correlate with prognosis in breast, colon and prostate cancer and can predict response to therapy. Neuroendocrine tumors (NETs) have not previously been reported to express EpCAM and have not been systematically assessed for presence of CTCs. We have therefore explored the expression of EpCAM in NETs and the detection of NET cells in the circulation.

#453 Activation of Hedgehog Pathway in Neuroendocrine Tumor
Introduction: Neuroendocrine tumors (NETs) are rare tumors and often follow an indolent course, especially the tumors of low-to-intermediate grade. The genetic etiology of sporadic NET is largely unknown. It is well-known that a significant number of patients with NETs may have harbored the slow-growing lesions since very a young age, suggesting it could result from alterations of pathways involved in development. Hedgehog (Hh) signaling has been found to be important in embryonic patterning, stem cell maintenance and tissue repair; and is normally silenced in most mature adult tissue. However, it frequently undergoes gain-of-function mutations or reactivation due to ligand overproduction and has been linked to the etiology of a variety of tumors.
