细胞衰老是一种稳定地阻止增殖的应激反应,它的重要性越来越被认识到。衰老在癌前肿瘤中普遍存在,而向恶性肿瘤的进展需要避免衰老。然而,由于恢复肿瘤抑制功能或使癌基因失活的干预措施,恶性肿瘤仍可能经历衰老。衰老的肿瘤细胞可以被免疫细胞清除,这可能会导致肿瘤的有效消退。标准化疗也有可能导致衰老,这可能是其治疗活性的部分原因。尽管这些概念在小鼠模型中得到了很好的支持,但将它们转化为临床肿瘤学仍然是一个挑战。
The importance of cellular senescence, which is a stress response that stably blocks proliferation, is increasingly being recognized. Senescence is prevalent in pre-malignant tumours, and progression to malignancy requires evading senescence. Malignant tumours, however, may still undergo senescence owing to interventions that restore tumour suppressor function or inactivate oncogenes. Senescent tumour cells can be cleared by immune cells, which may result in efficient tumour regression. Standard chemotherapy also has the potential to induce senescence, which may partly underlie its therapeutic activity. Although these concepts are well supported in mouse models, translating them to clinical oncology remains a challenge.
