贝伐珠单抗联合化疗对转移性结直肠癌患者血清EGFR及HER表达的影响研究

目的 探讨贝伐珠单抗联合化疗对转移性结直肠癌患者血清表皮生长因子受体(EGFR)及人表皮及不良反应生长因子受体(HER)表达的影响.方法 选取2013年1月至2016年10月在该院接受治疗的转移性结直肠癌患者60例为研究对象,分为试验组(贝伐珠单抗联合mFOLFOX-6化疗方案)和对照组(mFOLFOX-6化疗方案),每组30例.观察两组患者的疗效及不良反应,采用ELISA检测患者血清中HER、EGFR的水平.结果 治疗后试验组患者治疗总有效率为53.33%,对照组33.33%,差异有统计学意义(P<0.05).治疗后两组患者血清中HER和EGFR水平均有不同程度的降低,试验组比对照组降低的更多,差异有统计学意义(P<0.05).两组患者不良反应发生率比较差异无统计学意义(P>0.05).结论 贝伐珠单抗联合化疗对转移性结直肠癌患者有较好的疗效.

Study on effect of bevacizumab combined with chemotherapy on expression of serum EGFR and HER in patients with metastatic colorectal cancer

Objective To investigate the effect of bevacizumab combined with chemotherapy on the expression of EGFR and HER in the patients with metastatic colorectal cancer .Methods Sixty patients with metastatic colorectal cancer treated in this hos-pital from January 2013 to October 2016 were selected and randomly divided into the experiment group (bevacizumab combined with FOLFOX-6 chemotherapy regimen) and control group (FOLFOX-6 chemotherapy regimen) 30 cases in each group .The curative effects were observed in the two groups .The levels of serum HER and EGFR were detected by enzyme-linked immunosorbent assay (ELISA) .Results The total effective rate after treatment in the experiment group was 53 .33% ,which in the control group was 33 .33% ,the difference was statistically significant (P< 0 .05) .After treatment ,the levels of serum HER and EGHR in the two groups were decreased to some extent ,moreover the experiment group had more decrease than the control group ,the difference be-tween the two groups was statistically significant (P<0 .05) .The occurrence rate of adverse reactions had no statistical difference between the two groups (P>0 .05) .Conclusion Bevacizumab combined with chemotherapy has good effect in the patients with metastatic colorectal cancer .
