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: Bone metastases have been described in up to 15% of patients with NETs and are associated with a worse clinical outcome. Here we investigate the role of CTCs as a marker of bone metastases in a large cohort of patients with gastroenteropancreatic NETs.Methods: To be eligible for the study, patients were required to be ≥ 18 years old, have histologically confirmed midgut or pancreatic NET (pNET) and metastatic disease measurable by RECIS...
