ABSTRACT

Objective: To study angiogenesis and its influencing factors in human non-small cell lung cancer(NSCLC). Methods: The values of intratumor microvessel density(IMVD) in 95 cases of NSCLC were determined and its correlation with pathological parameters was analyzed. The relationship between IMVD and expressions of MMP-2,MMP-9,TIMP-2,VEGF,b-FGF,CD44v6,NOS2,NOS3 and E-cad in NSCLC was assessed. Results: There was active tumor angiogenesis of NSCLC, and the values of IMVD were correlated with clinicopathological stages of NSCLC and lymph nodes metastasis. The values of IMVD in positive expressions of VEGF, b-FGF, MMP-2, TIMP-2,CD44v6,NOS2 and NOS3 were significantly higher than that in negative expressions, opposed to the expression of TIMP-2 and E-cad. Conclusion:IMVD is a valuable marker for evaluating stages and metastasis of NSCLC. MMP-2, TIMP-2, VEGF, b-FGF, CD44v6, NOS2, NOS3 and E-cad may take part in the regulation of angiogenesis in NSCLC.
