Significantly lower serum iron (11μmol/l vs. 19μmol/l, p<0.05) and transferrin saturation (21% vs. 30%, p<0.01) but higher ferritin level (314μg/l vs. 150/107μg/l, p<0.01) was detected in a small retrospective study of 34 consecutive patients with small cell carcinoma of the lung and 103 healthy subjects [13]. This evidence concerns the gene TF and small cell lung carcinoma.
