鼻咽癌是发生于鼻咽腔顶部和侧壁的恶性肿瘤,在我国南方较为常见,严重威胁着患者的健康。近年来,随着鼻咽癌的诊断和治疗方法的不断改进,局部病灶控制率得到了大大提高,而远处转移甚至骨转移常常成为鼻咽癌患者治疗失败的首要原因[1]。 Nasopharyngeal carcinoma is a malignant tumor that occurs in the top and side of the nasopharyngeal cavity, which is more common in the south of our country and seriously threatens the health of patients. In recent years, with the continuous improvement of the diagnosis and treatment of nasopharyngeal carcinoma, the control rate of local lesions has been greatly improved, and distant metastases and even bone metastases are often the primary cause of treatment failure in patients with nasopharyngeal carcinoma [1].
