Evaluation of randomized preoperative and postoperative radiation therapy for supraglottic carcinoma. Preliminary report.

One hundred and ten patients with supraglottic squamous cell carcinoma have been randomized for preoperative radiation therapy and surgery versus surgery and postoperative radiation therapy. Data have been analyzed on 94 patients in this preliminary report. The differences between the two groups with respect to local control and survival are not statistically significant at this time. Additional accrual and continued follow-up are necessary in order to make a more definite treatment comparison.
