Abstract PDF: Radiotherapeutically, nasopharyngeal caner is an important disease in Korea. Because of its blind anatomic location, early detection is relatively uncommon. Clinically, most of cases are locally advanced and nodal involvements are common. Recently better understanding of nature of the disease and improvement of radio – therapy technique permit better treatment result, including locoregional control and survival rate, and minimal normal tissue damages comparing with previously published date. We analyzed 31 patients of pathologically proven and previously untreated naso – pharyngeal carcinoma with different treatment techniques, retrospectively. Minimal and maximal follow up period of the survivor is 6 months and 68 months, respectively. Thirteen patients with squamous cell carcinoma are included in this analysis. The median age is 49 years (range from 20 to 64 years). Twenty two patients are stage III. Eleven patients are treated with radiotherapy alone and 20 are treated with combined modalities treatment. The degree of response after radiotherapy are categorized by 3-classes, i,e. complete response, partial response. In spite of similarities of complete response rate and 1-year survival rate between two different treatment techniques, those patients with undifferentiated carcinoma appear to benefit from the adjuvant chemotherapy. In addition, systemic failure is more suggest that adjuvant therapy in the radiotherapeutic management of nasopharyngeal cancer needs additional research according to histologic types and future extensive clinical trials.

Abstract PDF: The primary treatment modality of malignant tumors of the nasopharynx is radiation therapy owing to its inaccessibility to surgical intervention. Over the last two decades there were many changes in techniques of delivery, which include the use of higher doses of radiotherapy, the use of wide radiation field, including the elective radiation of the whole neck, the combined use of brachy- and teletherapy, and the use of split-course therapy. In spite of these advances local and regional recurrences remain the major cause of death. As a boost therapy after external irradiation, high-dose-rate intracavitary irradiation using remote control afterloading system (RALS) was used in two patients. Our results were satisfactory, however, this procedure should only be performed by those who have developed enough expertise in the use of intracavitary techniques for the treatment of nasopharyngeal cancer and have a supportive team including a physicist, dosimetrist, nurse, and trained technologist.
