原发性三叉神经痛靶区勾画和计划设计指南

Guideline of target delineation and treatment planning for primary trigeminal neuralgia

立体定向放射外科是原发性三叉神经痛的重要治疗方式。规范开展放射外科治疗对患者疼痛的控制和生活质量的提高具有重要意义。本指南涵盖了基于伽玛刀、射波刀等不同系统下原发性三叉神经痛放射外科治疗过程的全流程质量标准,包括靶区定位和勾画、计划设计与优化、危及器官剂量限制和疼痛复发的影响因素及处理方式。以期基于不同单位实际条件及患者治疗情况,提高各级放疗单位针对原发性三叉神经痛放射外科治疗的规范化水平。

Stereotactic radiosurgery stands as a pivotal therapeutic modality for primary trigeminal neuralgia.Standardized implementation of radiosurgical intervention holds paramount significance in alleviating patients'pain and enhancing their quality of life.This guideline encompasses comprehensive quality standards throughout the process of radiosurgical treatment for primary trigeminal neuralgia using various systems such as Gamma Knife and CyberKnife,including target localization and delineation,plan design and optimization,constraints on doses to organs at risk,and factors influencing pain recurrence along with their management.The aim is to elevate the standardization level of radiosurgical treatment for primary trigeminal neuralgia across all levels of radiation therapy units,considering the practical conditions of different facilities and treatment circumstances of individual patients.
