Background: The identification and characterization of CTCs as part of a minimally invasive “liquid biopsy” has potential as a real-time biomarker in cancer patients. Using blood samples from NET patients, we evaluate the epitope-independent Parsortix, which enriches CTCs based on size and rigidity, and compare to the EpCAM-dependent CellSearch platform.Methods: About 10 patients with histologically confirmed metastatic NET had synchronous 7.5 ...

Background: Immunotherapy is currently being explored in many tumour types with encouraging results, but has not yet been evaluated in neuroendocrine tumours (NET). Our aim is to characterise the immune landscape of NET and determine which immune-modulatory pathways control the tumour infiltrating lymphocytes (TILs) in order to develop a rational approach for immunotherapy in this tumour type.Methods: Peripheral blood and fresh tissue was obtained from c...
