چکیده انگلیسی:
Background: Squamous cell carcinoma (SCC) is the most frequent malignancy of the head and neck (HN) region. We here evaluated associations of stromal cell derived factor-1 (SDF-1or CXCL12) and its receptor, CXCR4, with HNSCCs. Materials and Methods: Sixty newly diagnosed HNSCC patients were enrolled in the patient group, and 28 healthy individuals in the control group. Plasma levels of CXCL12 and CXCR4 were measured using ELISA kits. Results: There was a significant difference in mean CXCL12, but not CXCR4, plasma levels between the patient and control groups (P=0.0001). No significant associations were found between mean plasma levels of either CXCL12 or CXCR4 with age, gender, tumor site, tumor size, lymph-node involvement or tumor stage. Conclusion: For the first time, our findings demonstrate a significant association between serum CXCL12 but not CXCR4 levels and HNSCCs.
