Sixty-seven patients with squamous cell carcinoma of the hypopharynx were treated at the Kochi Medical School from 1983 to 1999. Of the 67 patients, 63 were male and 4 were female, and the mean age was 62 years. The locations of primary lesion were the pyriform sinus (45 cases), the posterior pharyngeal wall (11 cases) and the postcricoid (11 cases). Three cases were in stage I, 9 in stage II, 17 in stage III, 38 in stage IV.
As for the primary treatment, 50 of 67 patients were treated with preoperative irradiation of 20-30 Gy followed by surgery, and 16 patients were treated with irradiation alone. One patient had no treatment because of poor general condition.
The cause-specific survival rate (Kaplan-Meier method) of all patients was 43.5％ at 5 years. In patients receiving the definitive treatment, N stage was significant for overall survival, but T stage was not.
