连续抽取中山医科大学肿瘤医院CT室1984年4月至1987年7月所有经病理证实,放射治疗前CT扫描的鼻咽癌572例,以CT显示肿瘤原发灶的准确范围为基础,采用多因素Cox模型,分析各受侵部位对预后的意义,探讨提高鼻咽癌生存率的关键因素。结果表明,正确的T分期是影响生存的最主要因素,其次是N分期。通过对原发病灶15个因素的筛选,按比例危险度的大小列出了主要影响生存的受侵部位。强调加强对颈动脉鞘区的完全控制是提高鼻咽癌生存率的关键因素之一。
Continuously extracted CT room of Tumor Hospital of Sun Yat-sen University of Medical Sciences. All pathologically confirmed from April 1984 to July 1987. 572 cases of nasopharyngeal carcinoma with CT scan before radiotherapy. Based on the exact range of CT primary tumor, based on multiple Factor Cox model was used to analyze the significance of each affected site for prognosis and to explore the key factors to improve the survival rate of nasopharyngeal carcinoma. The results show that the correct T staging is the most important factor affecting survival, followed by N staging. Through the screening of fifteen factors of the primary lesions, the affected areas that mainly affect the survival were listed according to the proportion of the proportional hazards. It is emphasized that the enhancement of complete control of the carotid sheath area is one of the key factors to improve the survival rate of nasopharyngeal carcinoma.
