摘要随着肿瘤近距离治疗和消融治疗技术的发展，临床疗效可以达到消融治疗的目的。本文首次提出立体定向近距离消融(stereotactic ablation brachytherapy，SABT)概念，同时将SABT分为两类：H-SABT和L-SABT。H-SABT是指高剂量率后装近距离消融治疗，L-SABT是指低剂量率近距离消融治疗，也就是临床常用的放射性粒子植入治疗。SABT具有大分割，短疗程；影像引导，精确性高；疗效确切，可以达到手术切除式的疗效；器官功能保留的特点。立体定向近距离消融治疗已逐渐形成了独立的微创治疗技术体系，未来在肿瘤治疗领域将占有一席之地。

abstractsThe development of tumor brachytherapy and ablation therapy leads to the concept of stereotactic ablation brachytherapy(SABT). It is categorized into H-SABT (high dose rate brachytherapy) and L-SABT (low dose rate brachy therapy). L-SABT is clinically used as radioactive seed implantation therapy. SABT is characterized with the following: hypofraction and short course of treatment, Image-guidance and precision ablation, exact curative effect and preserved organic functions. SABT has gradually become a new disciplinary system and will play an important role in cancer treatments.
