摘要:

周期蛋白依赖性激酶4/6(CDK)4/6抑制剂是一类新型分子靶向药物,可通过抗血管生成、抑制DNA损伤修复以及抑制哺乳动物雷帕霉素靶蛋白信号转导起到放疗增敏作用。现有临床试验证实放疗联合CDK4/6抑制剂可有效控制乳腺癌转移病灶的局部症状,延长无进展生存期,且与单独使用CDK4/6抑制剂相比,联合治疗并未明显增加不良反应的发生率及严重程度;但也有联合治疗的个例发生放射野内正常组织严重不良反应的报道,其疗效与安全性尚需更多基础研究和临床研究加以明确。

Abstract:

Cyclin-dependent kinase (CDK) 4/6 inhibitors are a new class of molecular targeted drugs, which can enhance radiotherapy sensitivity by anti angiogenesis, inhibiting DNA damage repair and inhibiting mammalian target of rapamycin signal transduction. Existing clinical trials have confirmed that radiotherapy combined with CDK4/6 inhibitors can effectively control the local symptoms of breast cancer metastases and prolong progression-free survival. Compared with CDK4/6 inhibitors alone, the combination with radiotherapy does not significantly increase the incidence and severity of adverse reactions. However, there are also reports about severe adverse reactions of normal tissue happened in the radiation field in individual cases of combined treatment, and its efficacy and safety need to be clarified by more basic and clinical observational researches.
