This is an analysis of 74 patients with 75 squamous cell carcinomas of the pharyngeal wall treated with radical irradiation at the University of Florida between October 1964 and December 1984. All patients have a 2-year follow-up and 69% have a minimum 5-year follow-up. All patients were treated with continuous-course irradiation: 56 with once-a-day fractionation and 18 with twice-a-day fractionation. Patients treated with the split-course technique are not included in this series. Sixty-three patients were treated with external beam irradiation alone; 11 patients underwent an interstitial implant to the primary lesion following external beam irradiation. The local control rates with irradiation are as follows: T1, 3/4; T2, 12/21; T3, 12/27; and T4, 2/10. Only two patients were salvaged by operation for a local recurrence following irradiation. There was an improvement in the rate of local control with the use of twice-a-day fractionation and a decrease in the rate of local control with the combination of external beam irradiation and interstitial implant, compared with external beam irradiation alone. The 5-year determinate survival rates by AJCC stage are as follows: I, no data; II, 4/9; III, 3/16; and IV, 1/18.
