鼻咽癌(NPC)是我国常见的鼻咽部恶性肿瘤,放疗是目前治疗NPC的主要方法,而放疗前对病变向周围浸润、扩散和转移与否的估计是决定放疗照射范围、剂量的重要依据。对于估计NPC的病变范围,CT已成为最可靠的方法之一,本文拟就此问题加以讨论。 材料和方法 搜集我院1990年-1993年行CT检查并经病理证实的NPC病人17例,男13例,女4例,年龄36-68岁。其中NPC伴颈部淋巴结转移者5例,NPC伴颅底转移者3例,同时伴颈部淋巴结和颅底转移者7例,累及鼻窦者2例(其中1例同时伴胸壁、胸骨及胸膜转移)。
Nasopharyngeal carcinoma (NPC) is a common malignant tumor of the nasopharynx in our country. Radiotherapy is the main method to treat NPC. However, the evaluation of the infiltration, diffusion and metastasis of the lesions before radiotherapy is to decide the scope of radiation exposure and the dose in accordance with. CT has become one of the most reliable methods for estimating the extent of NPC lesions and this article is intended to address this issue. Materials and Methods In our hospital from 1990 to 1993 collected 17 cases of pathologically confirmed CT and pathologically confirmed NPC patients, 13 males and 4 females, aged 36-68 years old. Among them, 5 cases were NPC with neck lymph node metastasis, 3 cases were NPC with skull base metastasis, 7 cases were accompanied by cervical lymph node and skull base metastasis, 2 cases involved sinuses (1 case was accompanied by chest wall, sternum and pleural metastasis ).
