Brachytherapy is an essential component of the treatment of locally advanced cervical cancers. It enables the dose to the tumor to be boosted whilst allowing relative sparing of the normal tissues. Traditionally, cervical brachytherapy was prescribed to point A but since the GEC-ESTRO guidelines were published in 2005, there has been a move towards prescribing the dose to a 3D volume. Image guided brachytherapy has been shown to reduce local recurrence, and improve survival and is optimally predicated on magnetic resonance imaging. Radiological studies, patient workflow, operative parameters, and intensive therapy planning can represent a challenge to clinical resources. This article explores the ways, in which 3D conformal brachytherapy can be implemented and draws findings from recent literature and a well-developed hospital practice in order to suggest ways to improve the efficiency and efficacy of a brachytherapy service. Finally, we discuss relatively underexploited translational research opportunities.
近距离放射治疗是局部晚期宫颈癌治疗的重要组成部分。它能在提高肿瘤剂量的同时,使正常组织得到相对保护。传统上,宫颈癌近距离放射治疗的剂量是针对A点设定的,但自2005年GEC-ESTRO指南发布以来,已逐渐转向针对三维体积设定剂量。影像引导近距离放射治疗已被证明可降低局部复发率、提高生存率,并且以磁共振成像为最佳依据。放射学研究、患者工作流程、手术参数以及精确的治疗计划对临床资源而言可能是一项挑战。本文探讨了实施三维适形近距离放射治疗的方法,并借鉴近期文献和成熟的医院实践经验,以提出提高近距离放射治疗服务效率和效果的方法。最后,我们讨论了相对未得到充分利用的转化研究机会。
