Cytokines most influential in separating the cancer types (F to remove ≥ 10) included FLT3L (highest in BrCA), GM-CSF (lowest in Eso), TNF-β (highest in Eso), EGF (lowest in NSCLC), IL-3 (lowest in NSCLC), CXCL10/IP10 (lowest in NSCLC), CCL22/MDC (lowest in Eso), IFNα2 (lowest in NSCLC, highest in BrCA), and VEGF (highest in BrCA), highest in BrCA). This evidence concerns the gene FLT3LG and cancer.
