鼻癌之治療結果

Purpose: To evaluate the treatment results of carcinoma of the nasal cavity in one single institution.Materials and Methods Forty patients with pathologically-proved carcinoma of nasal cavity received definite treatment such as surgery alone (4 cases, 10%), radiotherapy alone (22 cases, 55%), or post-operative radiotherapy (14 cases, 35%). Staging system of the Florida University was used in this study. Absolute survival, cause-specific survival, local control, and regional neck control were calculated.Results The 5-year local control rates for stage Ⅰ through stage Ⅲ were 76%, 84% and 55%, respectively. The overall 5-year and cause-specific survival were 54% and 64%, respectively. Overall five-year survival for stage Ⅰ through Ⅲ were 88%, 60% and 30%, respectively. Five-year survival of different treatment methods by operation and postoperative radiotherapy, radiotherapy alone, and operation alone revealed 63%, 45% and 75%, respectively.Conclusion: Initial stage and neck nodal status were significant prognostic factors. Treatment methods, age, gender, histology, and sites of tumor origin were not significant factors. Elective neck irradiation might have no significant benefit for the prevention of neck failure.
