Purpose : The purpose of this study was to evaluate the efficacy of curative radiotherapy in the management of supralottic cancer. Materials and Methods : Twenty-one Patients with squamous cell carcinoma of the supra1ottis were treated with radiotherapy at Gyeongsang National University Hospital between 1590 and 1994. Median follow-up period was 36 months and $95\%$ were observed for at least 2 years. Results : Actuarial survival rate at 5 years was $39.3\%$ for 21 patients. The 5-rear actuarial survival rate was $75.0\%$ in Stage I, $42.9\%$ in Stage II, $33.3\%$ in Stage III and $28.6\%$ in Stage IV(p=0.54), The 5-year local control rate was $52.0\%$ for 21 patients. The 5-rear local control rate was $75.0\%$ in Stage I, $57.1\%$ in Stage II, $66.7\%$ in Stage III, and $28.6\%$ in Stage IV(p=0.33). Double primary cancer was developed in 3 patients and those were all esophageal cancers. Conclusion : In early stage(Stage I and II) supralottic cancer, curative radiotherapy would be a treatment of choice and surgery would be better to be reserved for salvage of radiotherapy failure. In advanced stage(Stage III and IV), radiotherapy alone is inadequate for curative therapy and combination with surgery should be done in operable patients. This report emphasizes the importance of esophagoscopy and esophagogram at the follow-up of patients with supra1ottic cancer.
