Methods: The specimens of 56 patients with lung cancer treated with surgerywere collected. Anti-Von Willebrand factor antibody was used to measure microvascular density (MVD)by means of SABC immunohistochemical technique, and antibody to basic fibroblast growth factor(bFGF) and its receptor (FGFR-1) to detect the expression of these three proteins in the tumortissues. The survival time was compared between low MVD and high MVD groups by the Kaplan-Meiermethod. Results: (1) The expression of MVD showed no significant difference in some clinicalcharacteristics, including sex, age, T stage, M stage and pathologic type, but significantdifference in N stage (P 【 0.01) and clinical stage (P 【 0.05). (2) Survival analysis showed thathigh MVD group was associated with a risk of death (P 【 0.01). (3) The expression of bFGF and FGFR-1were both related to lymphatic metastasis and clinical staging (P 【 0.05). (4) Significantdifference was seen between low MVD and high MVD groups in the bFGF expression in lung cancer (P 【0.01), whereas no correlation in FGFR-1. (5) High co-expression of bFGF and FGFR-1 was consistent intumor cells. Conclusion: (1) MVD is a good prognostic factor for patients of lung cancer, and thesame as bFGF. (2) The angiogenesis may be induced after bFGF binding to FGFR-1.展开更多
