放射性核素近距离治疗肿瘤的研究新进展

New progress in the research of radionuclides for tumor brachytherapy

放射性粒子组织间近距离治疗肿瘤虽已取得成功 ,但仍有许多问题尚未解决。该文回顾性综述了近距离治疗肿瘤的最新研究成果 ,包括放射性核素的选择、不同源的形式对剂量学分布的影响、治疗质量的保证、近距离治疗在空腔脏器肿瘤治疗中的应用以及近距离治疗的新趋势和展望。

Interstitial brachytherapy with radionuclide seeds has been successfully used for the treatment of cancer. But there are some problems remain to be solved. This review focus on some recent advances in the study of brachytherapy, including the option of radionuclides, the influence of dosage distribution by using different sources, the quality assurance, the application of brachytherapy in hollow visceral neoplasm,and new trends in brachytherapy.
