摘要
目的:探讨VEGFD/VEGFR3信号通路在声门上型喉癌淋巴结转移过程中所起的调控作用。方法:应用RTPCR方法检测VEGFD及其受体VEGFR3在声门上型喉癌交界区癌组织、癌旁组织及正常喉黏膜组织的表达水平。结果:有淋巴转移组VEGFD及其受体VEGFR3癌组织表达分别为2.070±0.074和2.022±0.061,癌旁组织分别为1.129±0.067和1.131±0.068,正常喉黏膜组织分别为0.450±0.048和0.478±0.064;无淋巴转移组VEGFD及其受体VEGFR3癌组织表达分别为1.327±0.060和1.328±0.054,癌旁组织分别为0.927±0.052和0.917±0.061,正常喉黏膜分别为0.385±0.033和0.335±0.040;两组VEGFD及其受体VEGFR3表达均为癌组织高于癌旁组织高于正常喉黏膜组织,差异有统计学意义,t≥5.651,P<0.001。有淋巴转移组癌、癌旁组织二因子表达均高于无转移组,差异有统计学意义,t≥2.388,P<0.05;两组正常组织二因子表达差异无统计学意义,t≤1.873,P>0.05。结论:VEGFD/VEGFR3信号通路与声门上型喉癌淋巴结转移密切相关,二者在癌组织、癌旁组织的高表达有可能作为预测淋巴结转移的指标。VEGFD/VEGFR3通路将有望成为声门上型喉癌淋巴结转移预防和治疗的新靶点。
OBJECTIVE:To investigate the control effect of VEGF-D/VEGFR-3 signal pathway during the process of lymph metastasis. METHODS: The VEGF-D/VEGFR-3 level in carcinoma tissue, para-tumor tissue and normal tissue of 50 supraglottic carcinoma patients (25N0 cases, 25N+ cases) was detected with reverse transcription polymerase chain reaction (RTPCR), then analyze the law. RESULTS: In lymph metastasis group, the levels of VEGF-D and VEGFR-3 are 2.070± 0.074, 2. 022±0. 061 in carcinoma area, 1. 129±0. 067, 1. 131±0. 068 in para-tumor area, 0. 450±0. 048, 0. 478±0. 064 in normal area respectively. In non-lymph metastasis group, the levels of VEGF-D and VEGFR-3 are 1. 327 ±0. 060, 1. 328± 0. 054 in carcinoma area, 0. 927 ± 0. 052, 0. 917 ± 0. 061 in para-tumor area, 0. 385±0. 033, 0. 335± 0. 040 in normal area respectively. In the 2 groups, The highest level of VEGF-D and VEGFR- 3 is carcinoma tissue, then is para-tumor, then is normal tissue; the differences are significant, t≥5. 651, P〈0. 001. The differences of VEGF-D and VEGFR-3 level in carcinoma and paratumor areas between the 2 groups are significant, t≥2. 388,P〈 0. 05; in normal tissue are insignificant, t≤1. 873, P〉0.05. CONCLUSIOS: The VEGF-D/VEGFR-3 signal pathway is correlated with supraglottic carcinoma lymph metastasis. Their high expression in carcinoma and para-tumor may predict supraglottic carcinoma lymph metastasis. The pathway may become a new target of preventing and treating supraglottic carcinoma lymph metastasis.
