Considering the squamous cell carcinoma group, AUC of all the tested parameters was significantly larger in comparison to AUC = 0.5 (borderline of the diagnostic usefulness of the test) (p < 0.001 in all cases), instead of adenocarcinoma group where the AUC of M-CSF did not reach statistical significance comparing to AUC = 0.5 (p = 0.0762). The gene discussed is CSF1; the disease is squamous cell carcinoma.
