               [摘   要] 抗体偶联药物(antibody⁃drug conjugate,ADC)作为一类创新疗法,在乳腺癌治疗中展现出显著效果。ADC由单克隆
                抗体、连接子、细胞毒性有效载荷偶联而成,综合了抗体的高特异性靶向能力和细胞毒性药物的高效杀伤力。然而,随着ADC
                在临床的广泛应用,乳腺癌患者中ADC的耐药性问题逐渐显露。文章概述ADC在乳腺癌领域的应用现状,并将ADC耐药机
                制归类为:靶抗原⁃抗体结合不足、ADC药物内化和转运途径受损、溶酶体功能受损、载荷释放异常、肿瘤对载荷缺乏敏感性以
                及细胞周期蛋白缺陷等。并且进一步汇总目前为克服ADC耐药性而研发的应对策略,包括ADC与其他药物(如化疗药物、靶
                向药物和免疫检查点抑制剂等药物)联合应用方案以及新型药物研发的进展,以求为ADC耐药的乳腺癌患者的治疗提供参考

               [Abstract] Antibody⁃drug conjugates(ADC),as a class of innovative therapies,have shown significant activity in breast cancer.
                ADCs are conjugated from monoclonal antibodies,linkers and cytotoxic payloads,which harnesses the highly specific targeting
                capabilities of antibodies along with the potent cancer killing effects of the cytotoxic drugs,demonstrating significant efficacy in the
                treatment of breast cancer. Nonetheless,as ADCs have been widely used in clinical practice,resistance to ADCs has been observed in
                breast cancer patients. In this review,we summarized ADCs’current applications in the treatment of breast cancer and classified the
                mechanisms underlying ADC resistance into several distinct categories as follows:inadequate antigen ⁃ antibody binding,impaired
                internalization and trafficking pathways of ADCs,defective lysosomal function,aberrant payload release,tumor insensitivity to the
                payloads,and cyclin deficiency. Furthermore,we summarized the contemporary strategies designed to address ADC resistance,such as
                the combined use of ADCs with other therapeutic agents,including chemotherapeutic agents,targeted therapies,and immune
                checkpoint inhibitors,as well as the development of new drugs. This review aims to offer reference options for the treatment of patients
                with ADC⁃resistant breast cancer.
