CXCR4 Expression on Circulating Tumor Cells (CTCs) and Their Association with Bone Metastases in Patients with Neuroendocrine Tumors (NET) Abstract #2022

Introduction: Bone metastases have been described in up to 32% of NET patients and are associated with a worse clinical outcome. Overexpression of CXCR4 in primary tumors appears predictive of skeletal involvement.
Aim(s): Here we investigate the role of CTCs as a marker of bone metastases and evaluate the expression of CXCR4 on CTCs as a potential predictor for skeleton invasion.
Materials and methods: Eligible patients were required to have histologically confirmed bronchial, midgut or pancreatic NET and metastatic disease by RECIST. Clinicopathological data were collected. Patients provided 7.5 mL blood samples which were analyzed by CellSearch. CXCR4 immunohistochemistry was performed on matched FFPE samples.

#1520 Osteotropism of NETs: Role of the SDF1/CXCR4 Axis in Regulating EMT
Introduction: NETs metastasize to the bone in up to 20% of patients. The SDF1/CXCR4 axis is a key determinant of osteotropism, and we showed that NETs overexpressing CXCR4 are more likely to develop bone metastases.

#922 Comparison of the Novel Cell Detector Method with Cell Search Technology in the Isolation of Circulating Tumor Cells in Neuroendocrine Tumors
Introduction: Circulating Tumor Cells (CTCs) have been detected in patients with neuroendocrine tumors (NET) using the CellSearch platform. Their presence is associated with a worse clinical outcome but less than 50% patients have detectable cells. The GILUPI Cell Detector is an EpCAM coated wire that is inserted into a vein and has been developed to increase capture of CTCs.
