摘要
目的:Leksell伽玛刀(LGK)是目前最精确的放射外科工具之一。然而,韩国各机构的LGK质量保证(QA)实践差异很大。在本研究中,我们的目标是识别和标准化关键的QA项目,分类为每日,每月,两年一次和年度协议,基于在全国16个医疗中心进行的调查。此外,对每个QA项目的公差值进行了审查,将其与美国医学物理学家协会工作组(TG-178)进行比较,并根据当地标准和监管要求进行调整,以建立独特的韩国伽玛刀放射外科(GKRS)公差。方法:调查集中于LGK Icon™/Esprit™和Perfexion™系统的QA实践。根据TG-178的指导方针,将QA项目分为每日任务、每月任务、两年任务和年度任务。16个参与调查的机构被要求对每个QA项目的重要性进行评分,从0(不重要)到5(非常重要)。4级或5级的项目被选出来创建一个国家优先列表。结果:11个每日、6个月、3个年度的QA项目被确定为高优先级。每日QA任务主要集中于辐射和患者安全,而每月的任务主要与剂量学验证有关。年度质量保证强调机械和剂量学检查。一年两次的评估没有被优先考虑,因为它们是由制造商的维护服务(Elekta AB, Stockholm, Sweden)常规执行的。结论:成功地为国内伽玛刀QA标准化提出了建议。持续的质量保证更新对于确保治疗安全性至关重要,特别是随着新的LGK模型的引入。这些发现可能有助于制定统一的GKRS国家质量保证指南。
Recommendations for Quality Assurance Guidelines for Gamma Knife Radiosurgery in Republic of Korea : A Multi-institutional Survey.
Objective: The Leksell Gamma Knife (LGK) is one of the most precise radiosurgical tools available. However, the quality assurance (QA) practices for LGK vary considerably across institutions in Korea. In this study, we aim to identify and standardize key QA items, categorized into daily, monthly, biannual, and annual protocols, based on a nationwide survey conducted at 16 medical centers. Additionally, the tolerance values for each QA items were reviewed, comparing them with the American Association of Physicists in Medicine Task Group (TG-178), and tailored to establish distinct Korean Gamma Knife Radiosurgery (GKRS) tolerances reflecting local standards and regulatory requirements.
Methods: The survey focused on QA practices for the LGK Icon™/Esprit™ and Perfexion™ systems. The QA items were categorized into daily, monthly, biannual, and annual tasks in accordance with the guidelines set by TG-178. Sixteen participating institutions were asked to rate the importance of each QA item on a scale of 0 (not important) to 5 (extremely important). Items rated 4 or 5 were selected to create a national priority list.
Results: Eleven daily, six monthly, and three annual QA items were identified as high priority. Daily QA tasks primarily focused on radiation and patient safety, whereas the monthly tasks were largely related to dosimetric validation. Annual QA emphasizes mechanical and dosimetric checks. Biannual evaluations were not prioritized as they were routinely performed by the manufacturer's maintenance service (Elekta AB, Stockholm, Sweden).
Conclusion: We succeeded in making recommendations for Gamma Knife QA standardization in Korea. Continuous QA updates are essential to ensure treatment safety, particularly with the introduction of new LGK models. These findings may contribute to the development of unified national QA guidelines for GKRS.
期刊介绍:
The Journal of Korean Neurosurgical Society (J Korean Neurosurg Soc) is the official journal of the Korean Neurosurgical Society, and published bimonthly (1st day of January, March, May, July, September, and November). It launched in October 31, 1972 with Volume 1 and Number 1. J Korean Neurosurg Soc aims to allow neurosurgeons from around the world to enrich their knowledge of patient management, education, and clinical or experimental research, and hence their professionalism. This journal publishes Laboratory Investigations, Clinical Articles, Review Articles, Case Reports, Technical Notes, and Letters to the Editor. Our field of interest involves clinical neurosurgery (cerebrovascular disease, neuro-oncology, skull base neurosurgery, spine, pediatric neurosurgery, functional neurosurgery, epilepsy, neuro-trauma, and peripheral nerve disease) and laboratory work in neuroscience.
