This study included both pro‐inflammatory (IL‐1B, IL‐6, IL‐8, IL‐12 (p40, p70), TNF‐α, and IFN‐γ), and anti‐inflammatory (IL‐4, IL‐6, IL‐10, TGF‐β), peripheral cytokine blood serum markers with no significant findings evident between cancer survivors and matched controls. This evidence concerns the gene IL10 and cancer.
