摘要
近年来,放射性粒子组织间植入治疗恶性肿瘤正得到日趋广泛的应用,取得了较大进展,其植入局部放射剂量高、周围组织剂量低、局部控制率相对较高,并具有操作简单、微创等优点。103Pd是一种新型的放射性粒子,与125I粒子相比,其半衰期较短,初始剂量较高,更适用于增殖较快的肿瘤组织。本文对其治疗原理、临床应用、并发症等方面进行综述。
For recent years,implantation of radioactive seeds has been increasingly used in the treatment of malignant tumors and remarkable clinical results have been achieved. The radioactive seed can produce high radiation dose in the implanted site, while in its surrounding tissues the radiation dose is very low. The technique is minimally-invasive and easy-to-manipulate, moreover, it carries relatively high local control rate for the tmnor, 103Pd is a newly-manufactured radioactive seed, which, compared to 125I seed, has shorter half-life period and higher initial dose. Therefore, 103Pd is more suitable for the tumors with higher proliferation rate. This article aims to make a broad overview of the principle, clinical application and complications of this new therapeutic method. （J Intervent Radiol, 2009, 18： 789-792）
