细胞可塑性与肿瘤治疗耐药的研究进展

Cellular plasticity and tumor therapy resistance: research advances

肿瘤的耐药、复发和转移是肿瘤治疗的首要难题。化疗、靶向治疗和免疫治疗对肿瘤患者效果显著,但持续时间短暂。尽管不同治疗方式下耐药性产生的机制各异,但由多种治疗手段引起肿瘤组织损伤和炎症共同介导的细胞可塑性的改变是肿瘤耐药产生的主要原因。本文综述了肿瘤细胞和免疫细胞可塑性改变对肿瘤发展的影响,以及联合免疫治疗和靶向治疗逆转肿瘤耐药的研究进展。

Drug resistance,tumor relapse and metastasis remain the main obstacles to the success of cancer treatments. Chemotherapies,targeted therapies and immunotherapies can successfully achieve remissions in cancer patients,but durable responses are rare. Although the mechanisms of diverse therapies vary,plasticity alteration of tumor and immune cells in response to therapy-induced tumor tissue injury and inflammation contributes to the development of drug resistance. This review summarizes research progress in the adaptive phenotypic plasticity of tumor cells and immune cells during tumor progression as well as the successful combination of targeted therapy and immunotherapy in cancer treatment to tackle resistance.
