调强放疗剂量验证实践指南

调强放疗剂量验证是放疗质量保证的重要组成部分,对保证调强放疗的安全和质量非常重要。我国尚无调强放疗剂量验证的系统指南和验证工具方法的具体推荐,验证结果的解读及其临床意义、验证不通过的原因分析及处理措施,不同机构使用的工具方法和实施细节差异很大。在国家肿瘤诊疗质控中心放疗质控专家委员会的组织领导下,经过现状调查、多中心测试、专家研讨、咨询、审定等方式完成了该指南。指南规定了开展调强放疗剂量验证的机构、组织、人员、设备、技术流程,及文档记录等方面的要求,以期改进调强放疗剂量验证工作的规范化开展。

Practice guideline of patient-specific dosimetric verification for intensity-modulated radiotherapy

Patient-specific dosimetric verification is an important component of quality assurance processes for intensity-modulated radiotherapy (IMRT), which plays a critical role in ensuring the safety and quality of IMRT. There has been no national practice guideline or explicit recommendations for tools and methods for patient-specific IMRT dosimetric verification in China. Interpretation and clinical significance of verification results, causes and management interventions for IMRT dosimetric verification failure, tools and methods and implementation details significantly differ among different institutions. Under the guidance and organization of Radiation Oncology Quality Control Committee, National Quality Control Center of Cancer Theranostics, this guideline was formulated based on the results of national survey, multi-center validation test, expert discussion, consultation and review. This guideline specifies the requirement of institution, organization, personnel, tools and device, technical workflow, and documentation,aiming to improve the standardized implementation of IMRT dosimetric verification procedures.
