摘要:

肿瘤再增殖是指癌症治疗后残存肿瘤细胞的增殖现象,是导致治疗失败和肿瘤复发的重要原因。放化疗后肿瘤的再增殖机制极为复杂,通常与放化疗诱导的肿瘤细胞死亡有关。放疗或化疗后,肿瘤细胞可能通过凋亡、坏死、自噬或焦亡等多种方式死亡。研究表明,这些不同的死亡方式可能与残存肿瘤细胞的再增殖相关。一方面,它们可能通过调节下游特定的信号通路直接影响残存肿瘤细胞的增殖;另一方面,它们可能通过改变肿瘤微环境中的肿瘤相关成纤维细胞、免疫细胞、内皮细胞等多种细胞的功能,进而重塑肿瘤微环境,为残存肿瘤细胞的增殖和转移创造条件。本文综述了放化疗后肿瘤细胞的死亡与残存肿瘤细胞再增殖之间的关系,并从细胞死亡方式与肿瘤微环境等多个角度分析治疗后肿瘤再增殖的可能机制,以期为预防癌症复发提供策略。

Abstract:

Tumor repopulation is the phenomenon of proliferation of residual tumor cells after cancer treatment, which is an important cause of treatment failure and tumor recurrence. The mechanism of tumor repopulation after radiotherapy or chemotherapy is extremely complex and is usually related to chemoradiotherapy-induced tumor cell death. After radiotherapy or chemotherapy, tumor cells may die in a variety of ways, including apoptosis, necrosis, autophagy, or pyroptosis. Studies have shown that tumor cell death may be associated with the tumor repopulation. On the one hand, they may directly affect the proliferation of residual tumor cells by regulating specific downstream signaling pathways. On the other hand, they may alter the functions of cancer-associated fibroblasts, immune cells, endothelial cells and other cells in the tumor microenvironment, then remodeling the tumor microenvironment in order to create conditions for the proliferation and metastasis of residual tumor cells. In this paper, we reviewed the relationship between tumor cell death and the repopulation of residual tumor cells after radiotherapy or chemotherapy, and analyzed the possible mechanisms of tumor repopulation from multiple perspectives, such as the mode of cell death and the tumor microenvironment, which is expected to provide a strategy for the prevention of cancer recurrence.
