Among the females, CRC patients showed significantly lower levels of serum iron (p = 0.0016), transferrin (p = 0.024), % transferrin saturation (p = 0.0019), and ceruloplasmin/transferrin ratio (p = 0.024), while no difference was observed in ceruloplasmin levels (p = 0.1059). The gene discussed is TF; the disease is colorectal carcinoma.
