The aim of the study to evaluate the prognostic significance of vascular endothelial growth factor receptor 1 and 2 (VEGFR1/2) expression levels and to correlate these levels with clinicopathological parameters in patients with cervical cancer.Forty-two patients with International Federation of Gynecology and Obstetrics Stage IIB-IVB cervical cancer were analyzed between January 2011 and December 2012. RNA expression levels of VEGFR1/2 were assessed by branched DNA-liquidchip technology and immunohistochemistry. Associations between RNA expression levels, important clinicopathological parameters, and patient survival were statistically evaluated.Higher VEGFR1/2 expression levels were predictive of poor overall survival (P = 0.009 and P = 0.024, respectively). Patients with higher VEGFR1 expression levels were associated with poorer progression-free survival than those with lower VEGFR1 expression levels (P = 0.043). In addition, patients with higher VEGFR1 expression levels were more likely to develop distant metastases than those with lower VEGFR1 expression levels (P = 0.049). Higher VEGFR2 expression levels were associated with larger tumor size (P = 0.037).VEGFR1/2 expression levels were prognostic factors for patients with cervical cancer. Higher VEGFR1/2 expression levels were also predictive of poor overall survival.
本研究旨在评估血管内皮生长因子受体1和2(VEGFR1/2)表达水平的预后意义,并将这些水平与宫颈癌患者的临床病理参数相关联。对2011年1月至2012年12月期间的42例国际妇产科联盟(FIGO)IIB-IVB期宫颈癌患者进行了分析。采用分支DNA液相芯片技术和免疫组织化学方法评估VEGFR1/2的RNA表达水平。对RNA表达水平、重要临床病理参数与患者生存率之间的关联进行统计学评估。较高的VEGFR1/2表达水平预示着总体生存率较差(分别为P = 0.009和P = 0.024)。VEGFR1表达水平较高的患者与VEGFR1表达水平较低的患者相比,无进展生存期较差(P = 0.043)。此外,VEGFR1表达水平较高的患者比VEGFR1表达水平较低的患者更易发生远处转移(P = 0.049)。较高的VEGFR2表达水平与肿瘤较大有关(P = 0.037)。VEGFR1/2表达水平是宫颈癌患者的预后因素。较高的VEGFR1/2表达水平也预示着总体生存率较差。
