비인강암에서 방사선치료와 항암화학요법의 병행요법의 예후인자로서의 의의 및 치료성적 = Prognostic Significance and Treatment Outcomes of Combination of Radiotherapy and Chemotherapy in Nasopharyngeal Cancer

다국어 초록 (Multilingual Abstract)

Background and Objectives：The diagnosis of a nasopharyngeal carcinoma is frequently made at an advanced stage. The anatomic complexicity of the nasopharynx makes a surgical approach difficult, so the radiation therapy is traditionally used as a primary option. Because of the high incidence of a locoregional failure folowing the radiotherapy and the distant metastasis, the combined treatment modality with the chemotherapy has been applied. The author attempted to investigate the clinical characteristics and the treatment outcomes of nasopharyngeal cancer patients treated with the combination of the radiotherapy and the chemotherapy. Subjects and Method：We retrospectively analyzed 82 patients who were diagnosed with the naso-pharyngeal carcinoma in Chonnam National University Hospital. Results：The cumulative survival rates for a 5-year period were 42%. The pathologic type, the clinical stage, the cranial nerve invasion, and the response to the radiotherapy were related to the survival rate of the Kaplan-Meier test (p<0.05). In the Cox proportional hazard model, only the response to radiotherapy was related to the survival rate (p＝0.05), as the clinical stage wasnt (p＝0.06). In the multivariate analysis betwen the responses to radiation and the clinical factor, the histological type (p＝0.018) and the response to the chemotherapy (p＝0.021) was statisticaly significant. Conclusion：The response to radiation is the most important in the patients survival. The cli-nical stage is a probable prognostic factor. Factors affecting the response to radiation are the histological type and the response to chemotherapy. (Korean J Otolaryngol 2002;45:897-901))
