Background  The search of useful serum biomarkers for the early detection of cervical cancers has been of a high priority. The activation of Macrophage-Colony Stimulating Factor (M-CSF) and Vascular Endothelial Growth Factor (VEGF) is likely involved in the pathogenesis and spread of cancer. We compared the plasma levels of M-CSF and VEGF to the ones of commonly accepted tumor markers CA 125and SCC-Ag in three groups of patients: 1. the cervical cancer group (patients with either squamous cell carcinoma or adenocarcinoma); 2. the cervical dysplasia group; 3. the control group.    Methods  This cohort study included 100 patients with cervical cancer and 55 patients with cervical dysplasia. The control group consisted of 50 healthy volunteers. The plasma levels of VEGF and M-CSF were determined using ELISA, while CA 125 and SCC-Ag concentrations were obtained by the chemiluminescent microparticle immunoassay (CMIA).    Results  The median levels of M-CSF and VEGF as well as CA 125 and SCC-Ag in the entire group of cervical cancer patients, were significantly different compared to the healthy women group. In case of both the squamous cell carcinoma and the adenocarcinoma groups, plasma levels of M-CSF and VEGF were higher compared to the control group. No significant differences in the studied parameters between the squamous cell carcinoma and the adenocarcinoma group were observed. The highest sensitivity and specificity were obtained for VEGF (81.18 and 76.00%, respectively) and SCC-Ag (81.18%; 74.00%) in the squamous cell carcinoma group and for VEGF (86.67%; 76.00%) in the adenocarcinoma group. The area under the ROC curve for VEGF was the largest in the adenocarcinoma group followed by the squamous cell carcinoma group (0.9082 and 0.8566 respectively).    Conclusions  Obtained results indicate a possible clinical applicability and a high diagnostic power for the combination of MSC-F, VEGF, CA 125 and SCC-Ag in the diagnosis of both studied types of cervical cancer.
