[摘要] 在我国,结直肠癌患者正呈现逐年上升的趋势,其治疗方法以手术为主,辅以放化疗,但效果却不甚理想。对于晚期结直肠癌的患者,已无法进行根治性手术切除,而放、化疗本身带来的毒副作用也严重影响患者的生活质量。近10年来,随着人们对西妥昔单抗和贝伐单抗等靶向药物的研究越来越深入,晚期结直肠癌患者再次迎来的新的曙光。在原有化疗药物的基础上使用靶向药物以进一步提高疗效也成为晚期结直肠癌一二线治疗新的发展趋势。此外,随着研究的不断深入,原发瘤部位的不同对靶向药物疗效的影响也成为医学界关注的焦点话题之一。本文就西妥昔单抗和贝伐单抗在晚期结直肠癌一二线治疗的研究进展以及左、右半结肠对靶向药物疗效的影响进行综述。

[Abstract] In China, the incidence of CRC is reportedly increasing over time. The treatment options including surgery, chemotherapy and radiotherapy, which are available depending mostly on disease stage. However, patients with advanced CRC have lost the chance of surgery,may also have a worse life because of chemotherapy and radiotherapy. With more and more studies on targeted therapy, such as Bevacizumab and Cetuximab, may shines a light for the patients with CRC. Chemotherapy combined with targeted therapy has become a new direction for the treatment of advanced CRC. Moreover, the association between tumor location and targeted therapy has become a hot topic. This review focuses on the progress of monoclonal antibody in the first-and second-tier treatment of advanced CRC and the effect of the left and right half colon on the efficacy of targeted drugs.

根據最近的数据,我国结直肠癌(CRC)发病率较以往有显著提高,年发病增长率为4.2%,已远远超过发达国家的平均水平,并呈现逐年增长的趋势,且发病患者趋于年轻化[1-2]。目前,CRC患者的治疗方式依然是以手术切除为主,但晚期CRC患者往往已出现远处转移,无法进行根治性手术切除,其治疗主要以化疗为主[3]。近年来,随着靶向药物的研究与发展,晚期CRC患者的寿命得到明显的延长,生活质量也得到相应的改善[4]。目前临床应用较多的分子靶向药物主要有两种:①针对表皮生长因子受体(EGFR)的西妥昔单抗;……
