Using the CyTOF data from Figures 1A, B, which was generated from melanoma subjects, we examined the importance of CD79b compared to CD117, a marker previously reported to be elevated on neutrophils in the blood of melanoma subjects (38), HLA-DR, a marker that appears on neutrophils in early-stage lung cancer patients (11), and CD19 and CD66b, as controls markers for B cells and neutrophils, respectively. This evidence concerns the gene CEACAM8 and lung cancer.
