This report is based on the experience of 65 consecutive patients with malignant tumor of the epipharynx seen in the Department of Otolaryngology, Mie University Hospital during the 20 years between 1961-1980.The male to female ratio was 2.4:1. Carcinoma was predominant in the 6th decade, whereas malignant lymphoma was predominant in the 2nd and 6th decades of life. Of the 65 cases, 47 (72.3%) were cancer and 17 (26.3%) were malignant lymphoma. The three most common cancer were squamous cell carcinoma (17), transitional cell carcinoma (14) and lymphoepithelioma (12). The majority of the cases have been treated by radiotherapy. The crude 3-year and 5-year survival rates were 53.7% and 45.7%, respectively. The survival rate of cancer was 52.9% and that of malignant lymphoma was 25.0%. Of 34 patients with cancer, the rate was 33.3% for squamous cell carcinoma, 71.4% for transitional cell carcinoma and 63.0% for lymphoepithelioma. The size of local tumor affected survival, but in this study the cervical lymph metastasis did not.
