鼻咽癌患者在长达 6-7 周的放疗过程中通常会出现体重减轻和肿瘤消退的情况。适应性放疗是一种基于图像引导技术的系统反馈控制方法，可根据治疗过程中新的影像学发现调整这些变化并优化放疗计划。越来越多的证据表明适应性放射治疗可以减少副作用、改善生活质量并加强疾病控制。然而，鼻咽适应性放疗的常规应用仍然相对有限。本综述讨论了适应性放疗的必要性、临床益处和局限性，并介绍了鼻咽癌适应性放疗策略的现状、挑战和未来前景。版权所有 © 2024。由 Elsevier Ltd 出版。

Patients with nasopharyngeal carcinoma often experience weight loss and tumor regression during the course of radiotherapy that lasts for up to 6-7 weeks. Adaptive radiotherapy is a systematic feedback control approach based on image-guided technology that adjusts these changes and optimizes the radiotherapy plans according to new imaging findings during treatment. There is growing evidence that adaptive radiotherapy can reduce side effects, improve the quality of life, and enhance disease control. However, the routine application of adaptive radiotherapy for nasopharyngeal remains relatively limited. This review discusses the necessity, clinical benefits, and limitations of adaptive radiotherapy, and presents the current state, challenges, and future perspective of adaptive radiotherapy strategies for nasopharyngeal carcinoma.Copyright © 2024.
