Conclusion: Topotecan has radiosensitization effect on cervical carcinoma HeLa cells, which shows dose dependent and treatment duration dependent characteristic. This effect is probably caused by post-injury repair, apoptosis and G_2/ M block of HeLa cells. 结论:拓扑替康对宫颈癌细胞系HeLa有放射增敏作用,且有剂量依赖性和用药时间选择性,其放射增敏机制可能与HeLa细胞放射后损伤性修复、细胞凋亡及G2/M期阻滞相关。
Conclusion Our study suggests that CMNa should enhance radiosensitivity on nasopharyngeal carcinoma, increase the short-term therapeutic response and decrease the radiotherapy dose without obvious toxicity. 结论CMNa合并放疗对鼻咽癌有增敏作用,可提高近期疗效,降低疗效达CR时所需的放射剂量,无明显毒副反应。
