药物治疗抵抗在临床实践中成为肿瘤治疗失败的主因。最近的研究指出,肿瘤细胞的耐药性可能源于其内部高度的细胞异质性,而这种异质性的基础则是肿瘤可塑性。肿瘤细胞可塑性可能引发一系列反应,包括对治疗的耐药性发展、免疫系统逃逸以及对周围组织和血管系统的侵袭和转移等。本文简要介绍肿瘤细胞可塑性的表现形式以及其在药物治疗抵抗的非遗传适应性机制与靶向治疗新策略。

Drug therapy resistance has emerged as a primary cause of treatment failure in cancer management．Recent research indicates that the resistance of tumor cells may stem from their high degree of intracellular heterogeneity,with the underlying basis being tumor plasticity．Tumor cell plasticity can trigger a cascade of responses,including the development of resistance to treatment,evasion of the immune system,and invasion and metastasis into surrounding tissues and the vascular system．This article provides a brief overview of the manifestations of tumor cell plasticity and its non-genetic adaptive mechanisms in drug therapy resistance,along with novel strategies for targeted treatment．
