  1. 31 patient blood samples and 10 healthy donor samples were processed through Vortex technology. These 31 samples were collected from 22 different NSCLC patients: 5 squamous, 17 adenocarcinoma, with 17 blood samples collected pre-treatment, 2 after the first cycle, and 11 during the treatment. 15 samples had ≥10 CTCs and were considered for further study, with 4 of them having a biopsy of the primary tumor available. (PDL1+), (PDL1−) and (UD) respectively indicate the number of CTCs per mL that are either identified as PD-L1 positive, PD-L1 negative or undetermined.
