近距离放射治疗的临床应用进展

Progress of clinical brachytherapy application

近距离放疗是现代放射肿瘤学的初始技术和不可缺少的组成部分。近年来,除了在妇科肿瘤和头颈部等肿瘤中仍继续被广泛应用外,单纯放射性粒子组织间放疗已成为早期前列腺癌的标准治疗手段之一,单纯近距离放疗可成为早期乳腺癌保乳术后放疗主要选择方法之一。本文重点介绍2005年美国放射肿瘤治疗学年会(ASTRO)中关于近距离放疗临床应用的现状,展望未来发展的方向。

Brachytherapy was the earliest technique of radiotherapy for the treatment of cancer and still is an important part of modern radiation oncology. It has been widely used as one of the modalities for gynecological cancer as well as head and neck cancer. In recent years, radioactive seed implantation has been proved to be one of the standard treatments for early stage prostate cancer, and brachytherapy alone is emerging as the major treatment for early stage breast cancer after lumpectomy. This article reviewed the current status of brachytherapy in clinical application as reported during the 2005＇annual ASTRO meeting and its prospected for future development.
