Wu et al. [26] reported that in NSCLC patients who were in advanced stages, an increased serum ferritin level was more common in patients accompanied with EGFR mutation than EGFR-wild patients (the optimal critical value of serum ferritin for females was 129.0 μg/L and for males 329.0 μg/L, respectively), with a statistically significant difference. This evidence concerns the gene EGFR and non-small cell lung carcinoma.
