本文收集我院1971年住院放疗鼻咽癌796例进行分析,讨论影响鼻咽癌预后的有关因素。年轻者预后较好,随年龄的增长,逐渐变差;病理分型的五年生存率以泡状核细胞癌高于低分化鳞癌;临床分期Ⅰ期的五年生存率最好,以Ⅰ至Ⅳ期逐渐下降;临床分型上行型与下行型五年生存率无差异,但上下行型最差;原发灶局限于鼻咽腔的五年生存率较好,超出鼻咽腔越广泛者越差;单侧颈淋巴结转移者预后优于双侧者;颈淋巴结转移N_1、N_2和N_3的五年生存率依次降低;肿瘤放射剂量以鼻咽5000—7000rad、颈淋巴结转移以4000—6000rad较好。
This article collected 796 cases of nasopharyngeal carcinoma hospitalized in our hospital in 1971 for analysis to discuss the factors that affect the prognosis of nasopharyngeal carcinoma. Young people have a better prognosis, and gradually worsen with age; the five-year survival rate of pathological type is higher in vesicular nucleus cell carcinoma than in poorly differentiated squamous cell carcinoma; the five-year survival rate of clinical stage I is the best. Phase IV gradually decreased; there was no difference in the five-year survival rate between ascending and descending clinical types, but the worst was the up-down type; the five-year survival rate of the primary lesion confined to the nasopharyngeal cavity was better, beyond the scope of the nasopharyngeal cavity The worse the patient, the better prognosis of patients with unilateral cervical lymph node metastasis, and the five-year survival rate of cervical lymph node metastases N_1, N_2, and N_3 decreased in turn; the tumor radiation dose was 5000-7000rad for nasopharyngeal and 4000-6000rad for cervical lymph node metastasis. better.
