Detection of Circulating and Disseminated Neuroblastoma Cells Using the ImageStream Flow Cytometer for Use as Predictive and Pharmacodynamic Biomarkers.

This is the first study to show that CTCs and DTCs are detectable in neuroblastoma using the ISx, with concurrently extracted cfDNA used for copy number profiling, and may be useful as pharmacodynamic biomarkers in early-phase clinical trials. Further investigation is required to determine whether CTC numbers are predictive biomarkers of BM response to first-line induction chemotherapy.
