目的:检测基质金属蛋白酶-7(MMP-7)和碱性成纤维细胞生长因子(bFGF)在非小细胞肺癌(NSCLC)组织中的表达情况,探讨 MMP-7、bFGF 与肿瘤内间质微血管密度(MVD)的关系及MMP-7、bFGF、MVD 与肿瘤转移的关系。方法采用免疫组织化学 SP 法检测原发性 NSCLC 石蜡包埋组织80例、正常肺组织40例中 MMP-7和 bFGF 蛋白的表达水平,比较 MMP-7、bFGF 在 NSCLC、正常肺组织中的表达情况及在 NSCLC 中的表达与淋巴结转移的关系;在 CD34染色切片上检测 MVD,检测NSCLC 中的 MVD 与 MMP-7、bFGF 表达的关系及与组织学类型、分化程度、淋巴结转移、TNM分期的关系。。结果MMP-7和 bFGF 在 NSCLC 组的阳性率分别为70.0%、65.0%,均高于正常肺组织组的12.5%和10.0%,差异有统计学意义(χ2=35.276,P =0.000;χ2=32.411,P =0.000);有淋巴结转移组MMP-7和 bFGF 的阳性表达率分别为83.0%、80.9%,无淋巴结转移组的表达率分别为51.5%和42.4%,差异有统计学意义(χ2=9.139,P =0.003;χ2=12.584,P =0.000);NSCLC 中 MMP-7和 bFGF 阳性病例组的 MVD 分别为46.78±11.11、45.05±10.97,高于阴性病例组的31.12±7.62、34.77±8.56,差异有统计学意义(t =5.831,P =0.000;t =5.364,P =0.000);有淋巴结转移组的 MVD 为61.32±21.61,高于无淋巴结转移组的40.52±18.31,差异有统计学意义(t =3.865,P =0.008);TNM分期中Ⅰ~Ⅱ期 MVD 为41.73±16.48,Ⅲ~Ⅳ期 MVD 为55.28±15.64,差异有统计学意义(t =2.531,P =0.013)。结论MMP-7与 bFGF 在 NSCLC组织中高表达,其表达的阳性率与淋巴结转移有相关性,且阳性病例组的 MVD 均显著高于阴性病例组,MVD 与淋巴结转移及 TNM分期有相关性,提示三者在 NSCLC侵袭转移过程中可能起到了重要的作用。

Objective To investigate the expressions of matrix metallopro-teinase-7 (MMP-7),basic fibroblast growth factor (bFGF)in NSCLC,and to elucidate the correlations among MMP-7,bFGF and MVD, as well as their relationships with cancer metastasis in NSCLC.Methods The expressions of MMP-7,bFGF and MVD were detected by immunohistochemical SP method in 80 cases of NSCLC and 40 cases of normal lung tissue,compare the expression of MMP-7 and bFGF in NSCLC and normal lung tissue,and then invest the rela-tionship between their expression and lymph node metastasis in NSCLC.The MVD was investigated within the CD34 positive slides,check the relationship between MVD and the expression of MMP-7 ,bFGF in NSCLC, and also its relationship with histology type,differentiation degree,lymph node metastasis and TNM stage. Results The positive ratesof MMP-7 and bFGF were significantly higher in NSCLC than those in normal lung tissue (70.0% vs 1 2.5%,χ2 =35.276,P =0.000;65.0% vs 1 0.0%,χ2 =32.41 1 ,P =0.000).The posi-tive rates of MMP-7 and bFGF were also significantly higher in group with lymph node metastasis compared to those group without lymph node metastasis (83.0% vs 51 .5%,χ2 =9.1 39,P =0.003;80.9% vs 42.4%,χ2 =1 2.584,P =0.000).The numbers of MVD were significantly higher in cases with MMP-7 and bFGF posi-tive expressions than those in cases with MMP-7 and bFGF negative expressions (46.78 ±1 1 .1 1 vs 31 .1 2 ± 7.62,t =5.831 ,P =0.000;45.05 ±1 0.97 vs 34.77 ±8.56,t =5.364,P =0.000).The number of MVD in group with lymph node metastasis was also significantly higher than that in group without lymph node metasta-sis (61 .32 ±21 .61 vs 40.52 ±1 8.31 ,t =3.865,P =0.008).The number of MVD in staging Ⅲ-Ⅳ group was significantly higher than that in stagingⅠ-Ⅱgroup (55.28 ±1 5.64 vs 41 .73 ±1 6.48,t =2.531 ,P =0.01 3).Conclusion The expression levels of MMP-7 and bFGF in NSCLC are high,and the positive rates of MMP-7 and bFGF are correlated with the lymphnode metastasis.The numbers of MVD are significantly higher in cases with MMP-7 and bFGF positive expressions than those in cases with MMP-7 and bFGF negative expre-ssions.MVD is correlated with lymph node metastasis and the TNM stage.It suggests that the expressions of MMP-7,bFGF and MVD may involve in the invasion and metastasis of NSCLC.
