摘要: 调强放疗逐渐成为鼻咽癌的主要治疗方式。其疗程一般为7~8周,随着治疗进行,患者口咽反应逐渐加重,体重下降,肿瘤组织退缩,靶区周围组织发生变化。这些变化将影响靶区及危及器官的剂量分布,因此调强放疗期间复位进行靶区修正是很有必要的。

Abstract: 【Abstract】Intensity modulated radiation therapy (IMRT) has become the mainstay of treatment modality for nasopharyngeal carcinoma (NPC). The whole treatment course generally continues 7 to 8 weeks. With the radiotherapy proceeding, the patients exhibit oropharyngeal reaction aggravating, weight losing and tumor shrinking, resulting in the changes of tumor target and surrounding tissue. Those changes may influence the dose distribution of tumor and organ at risk. It is necessary to modulate target volume during radiotherapy of NPC.
