HER2阳性结直肠癌研究进展

表皮生长因子受体2（HER2）是肿瘤发生、发展过程中的癌基因,在7%的结直肠癌患者中表达,与表皮生长因子受体单克隆抗体的耐药相关。随着CRC治疗困境的出现,以及靶向HER2为乳腺癌、胃癌患者带来生存获益,HER2在CRC中的意义及抗HER2治疗的预后价值被广泛关注,围绕HER2阳性CRC的临床研究亦不断开展。目前,CRC中HER2阳性的诊断标准已逐渐统一,HER2靶向治疗如单克隆抗体、酪氨酸激酶抑制剂、抗体-药物耦联物及HER2相关免疫治疗的单独或联合治疗策略在HER2阳性CRC中显示出较好的疗效,能为患者带来生存获益,本文就此方面的研究进展作一综述。

Research Progress of HER2 Positive Colorectal Cancer

Epidermal growth factor receptor 2 (HER2) is an oncogene involved in tumour genesis and progression. It is expressed in 7% of patients with colorectal cancer (CRC) and is associated with drug resistance of epidermal growth factor receptor monoclonal antibodies. With the emergence of the therapeutic dilemma of CRC and the survival benefits of targeting HER2 for patients with breast cancer and gastric cancer, the significance of HER2 in CRC and the prognostic value of anti-HER2 therapy have been widely concerned, clinical researches on HER2-positive CRC have been continuously carried out. Currently, the diagnostic criteria for HER2 positive CRC have gradually been unified. HER2-targeting therapies such as monoclonal antibodies, tyrosine kinase inhibitors, antibody-drug coupling and HER2-related immunotherapy alone or in combination have shown good efficacy and brought significant survival benefits for HER2 positive CRC. This paper reviews the research progress of HER2 in CRC.
