Research output: Contribution to journalArticlepeer-review


Sixty nine patients with carcinoma of the oral cavity, especially those treated by radiotherapy during the 5 year period from 1982 through 1987 were reviewed. Sixty three of 67 patients (94%) had received radiation therapy with curative, adjunctive or palliative intent. In the cases when external irradiation was applied, the antitumor agents were combined in most cases. As the curative therapy for tongue cancer, 23 of 33 patients were treated with radiotherapy alone, i.e., interstitial implants alone or in combination with external irradiation. The 5-year cumulative survival rate for all cases was 55.4%; for stage I and II was 84%, and for stage III and IV it was 22.7%.
