CXC chemokine ligand 4 (CXCL4) is predictor of tumour angiogenic activity and prognostic biomarker in non-small cell lung cancer (NSCLC) patients undergoing surgical treatment.
Biomarkers : Biochemical Indicators of Exposure, Response, and Susceptibility to Chemicals 2016 July
OBJECTIVE: To evaluate the association of CXC chemokine ligand 4 (CXCL4) plasma levels with tumour angiogenesis in non-small cell lung cancer (NSCLC) and to assess association of CXCL4 with clinical outcomes.
PATIENTS AND METHODS: Fifty patients with early stage NSCLC who underwent pulmonary resection. CXCL4 levels were analysed by ELISA. Angiogenesis was assessed by immunohistochemistry, and microvessel density (MVD) count.
RESULTS: There was positive correlation between MVD and CXCL4 levels. Patients with higher CXCL4 levels had worse overall and disease-free survival.
CONCLUSIONS: Plasma levels of CXCL4 are associated with tumour vascularity. Increased CXCL4 levels in NSCLC patients undergoing treatment may indicate active cancer-induced angiogenesis associated with relapse and worse outcome.
