ABSTRACT
From 1984 to 1988, fourt two patients with nasopharyngeal cancer were treated at the Department of Radiation Oncology in Kyungpook National University Hospital. Thirteen patients refused treatment and the median survival time was 7.8 months. Twenty nine patients received a full course of radiation at least 70 gy to the primary site and 60 gy to the nodal sites. These patients were all belonged to stage III or IV. The local control rate was 75% in squamous cell carcinomas, and all the patients with lymphoepithelioma showed a complete response. Overall locoregional failure was 27.6%. Distant metastasis was the predominant pattern of failures; 4/6 in lymphoepithelioma, 4/10 in squamous cell carcinoma. The Three-year-survival rate for squamous cell carcinoma was 40.5%, and for lymphoepithelioma 25.9%, respectively. This may be due to the more frequent distant metastases in lymphoepithelioma and ineffective chemotherapy. No survival correlation was found with the level of neck node involvement. Though adjuvant chemotherapy was found to be of no benefit in overall survival, more prudent and aggressive chemotherapy would be necessary.
