摘要:

西妥昔单抗是治疗转移性结直肠癌(mCRC)重要的分子靶向药物,可增加化疗疗效并延长患者生存期,但是部分患者对该类药物存在不敏感或耐药现象,其分子机制尚未完全揭示。随着表皮生长因子受体(EGFR)信号通路研究的深入,KRAS、BRAF、PTEN、PIK3CA等基因的改变以及微小RNA(miRNA)的多态性逐渐被证实与西妥昔单抗耐药相关,最新的研究亦表明Wnt信号通路及其负性调控因子RNF43可能与西妥昔单抗耐药相关。总结mCRC西妥昔单抗耐药分子机制的研究进展,可为后续寻找治疗药物奠定理论基础。

Abstract:

Cetuximab has become an important molecular targeted drug for the treatment of metastatic colorectal cancer (mCRC), which increases the curative effect of chemotherapy and prolongs the survival time. However, some patients develop insensitiveness or resistance to cetuximab, while the complicated molecular mechanisms are not quite clear. With the deep research in epidermal growth factor receptor (EGFR) signaling pathway, the genetic alteration of KRAS, BRAF, PTEN and PIK3CA and polymorphism of microRNA (miRNA) have been proved to associated with cetuximab resistance. Wnt signaling pathway with its negative regulator RNF43 is also considered to be related with cetuximab resistance in recent studies. The review of the progress on molecular mechanisms of cetuximab resistance in mCRC can establish theoretical basis for finding out reasonable drugs to overcome the resistance.
