60例上皮源性鼻腔癌的临床疗效分析

目的：评价上皮源性鼻腔癌的临床疗效及影响预后的因素。方法：回顾性分析1995－1992年收治的60例上皮源性鼻腔癌。其中单纯放射治疗34例,手术＋放射治疗26例。生存统计采用Kaplan-Meier法,组间比较采用Log-rank检验,多因素分析采用Cox模型。结果：总5年生存率为55．9％,10年生存率为36．9％。早期患者（I、Ⅱ期）的5,10年生存率分别为79．0％和57．9％,晚期患者（Ⅲ、Ⅳ期）的5,10年生存率则分别为44．1％和26．0％,二者差异有显著性（P＝0.005)。手术＋放射治疗与单纯放疗的生存率差异无显著性（P＝0．33）,鳞癌的生存率明显低于腺癌（P＝0．04）,初诊时颈部有淋巴结转移者的5,10年生存率低于无颈部淋巴结转移者（P＝0.09).结论:治疗方式`颈部淋巴结转移对预后无明显影响,而病理类型`临床分期对预后有显著影响.

Prognostic factors of 60 nasal cavity carcinoma patients

OBJECTIVE: To evaluate the treatment modalities and the prognostic factors of nasal cavity carcinoma. METHODS: A retrospective study was done on 60 nasal cavity carcinoma patients treated from 1985 to 1992. Thirty-four patients received radiotherapy alone and 26 patients received surgery plus radiotherapy. Kaplan-Meier method was used to evaluate the survival, Log-rank test to assess the difference between these two groups and Cox proportional hazard model by multivariate analysis. RESULTS: The overall 5- and 10-year survival rates were 55.9% and 36.9% respectively. The 5- and 10-year survival rates were 79.0% and 57.9% in patients with early lesions (stage I, II) and 44.1% and 26.0% in patients with advanced lesions (stage III, IV) (P = 0.005). There was no significant difference in the survival rate between radiotherapy alone and radiotherapy plus surgery (P = 0.33). Patients with squamous cell carcinoma had obviously poorer survival rate than patients with adenocarcinoma (P = 0.04). Patients with positive nodes had a lower survival rate compared with negative node patients (P = 0.09). CONCLUSION: Histological type and clinical stage, but not method of treatment or neck node metastasis, are the important prognostic factors.
